Growing Peppers Without Watering

Growing peppers in the backyard garden can be frustrating.  Even though peppers are not as prone to damage by insects as other plants like squash or eggplants, they are very finicky overall.  Pepper plants frequently fall over if not staked, required near daily watering yet produce relatively little, and many varieties don't do well with hot temperatures. Peppers also wilt in during the height of the summer.   Finally, almost all weeds grow faster than pepper plants, requiring you to constantly be looking out for soil invaders near your pepper plants. After a few years, especially in hot climates, gardeners decide it is not worth the effort and many stop attempting to grow these plants.

This is a shame, especially as a new device makes it extremely easy to grow peppers.  The device, called the Groasis Waterboxx PlantCocoon, or Waterboxx for short, collects dew and rain water, stores it, and then slowly releases it to the roots of a growing plant.  It doesn't require electricity and, after set up, may not require any manual watering, especially for peppers.

The Waterboxx: a tree or garden plant in planted in the central opening, water is collected from dew and rainfall from the corrugated tan lid, funneled through siphons (shown here in red) into the green reservoir, and then slowly released autonomously through a wick to the plant roots below.  Image from Groasis.com  


First, let's discuss bell peppers. These peppers are some of the most popular to grow because they are the most useful in the kitchen and most expensive at the store- frequently about $1 per pepper, even in season.  However, these pepper plants will drop their blooms if daytime temperatures get about 90 degrees Fahrenheit consistently.  The Waterboxx, however, stores water and keeps the base and roots of the plant cool, relieving some heat stress from this plant.  It also provides consistent moisture and prevents any weeds from growing around the pepper.  If you do live in an extremely hot climate (like the desert southwest), however, we would suggest 30% shade cloth over your pepper plants to prevent overheating.

Two bell pepper plants in the height of the summer heat - with no water at all since planting, besides rainfall and dew. The Waterboxx not only waters these plants but blocks out any competing weeds.  

So, the Waterboxx can be used to grow bell peppers well.  How about long peppers?  Yes, the Waterboxx is especially well suited to these peppers.  Below you can see long peppers thriving in the Waterboxx.  These two plants, in one Waterboxx produced over 100 peppers, with no watering after planting.


The Waterboxx growing long peppers - over 100 peppers from this plant without any watering after planting - a truly impressive feat!
How about jalapenos?  Will the Waterboxx help grow this delightful variety?  Yes, with incredible yields, as well.  Two jalapeno plants in a single Waterboxx with no watering or care after planting grew over 80 peppers!

Two jalapeno plants growing in a Waterboxx - produced over 80 peppers with no watering, no weeding, and no other care after planting.  


Finally, we come to the king of the hot peppers, the habanero.  The Waterboxx also can be used to grow this pepper, with large yields and no work after planting.


The Waterboxx growing two habanero pepper plants with yellow habaneros scattered through the upper leaves - no watering, weeding, fertilizing, muclching, or any other work since planting!

There has never been a device like the Waterboxx for growing peppers - it can completely eliminate the need for any watering after planting, completely eliminate weeding, eliminate mulching, and help produce high yields.  It also encourages tall, straight plants with its unique figure 8 central opening.

Atmosphere's Carbon Dioxide Passes Key Level

This past month, the world’s longest running carbon dioxide measurement site measured atmospheric carbon dioxide levels to be above 400 parts per million.  While this has happened before, it has never happened in the height of the northern hemisphere summer, when carbon dioxide levels reach a yearly low due to growth of vegetation.

This is a significant milestone, and it is almost certain that no one now living will see levels drop below 400 ppm during their lifetime.  When observations at this site in Hawaii started in the 1950s, the average level of carbon dioxide was 315 ppm.

From http://www.esrl.noaa.gov/gmd/obop/mlo/programs/coop/scripps/co2/co2.html, public domain
This carbon dioxide is of course the most prevalent greenhouse gas, as well as the main cause of ocean acidification.  There are some benefits to the current level of carbon dioxide (we likely have postponed the next ice age, for one).  However, clearly continued increase in carbon dioxide levels will continue to change climate, raising sea level while also making it harder for many marine organisms to flourish (due to ocean acidification).  We have reached a point where we need to stop increasing carbon in the atmosphere.

For reference, carbon dioxide hasn't been this high in the atmosphere at any time during Homo sapiens tenure on this planet.  
Carbon Dioxide levels are higher now than at any time in the last 800,000 years, at least.

Almost all proposed "solutions" to this problem have really been efforts to just decrease how much carbon dioxide we are emitting, rather than removing any carbon dioxide.  This is futile, as almost all human productive activity produces carbon dioxide (even making steel for wind turbines and mining lithium for batteries).  Also, as more of the world electrifies, energy consumption and therefore carbon dioxide emissions will continue to increase from the developing world.  You can hardly blame the people of India and Africa for wanting a standard of living we enjoyed 60 or 70 years ago in the U.S.  This standard of living, currently, is only made possible by fossil fuels.

So, what is to be done?  We cannot stop using fossil fuels, so are we just stuck with the consequences of our emissions?  The answer is a resounding no.  Fossil fuels, specifically coal, are the compressed and aged products of ancient forests of massive trees, buried before organisms evolved that could readily dissolve lignin in wood. If we could replant reasonable numbers of massive trees, we could begin counteracting this emission of carbon dioxide.  We have calculated that some single trees (for example, the General Grant Sequoia in California) have stored more than a lifetime's emissions of carbon dioxide.  Even if we didn't plant massive trees, planting large numbers of smaller trees on currently dry, barren land would make the land productive and carbon sequestering.  

How is this to be done?  Planting sequoias outside their current range and planting trees in dry, barren areas has been made entirely possible by new technology, called the Groasis Waterboxx.

A schematic cutaway view of the Groasis Waterboxx (from Groasis.com).  Water is collected on the tan lid, funneled through the siphons shown in red to the green reservoir, and slowly released to the roots of the growing tree via the white wick.

The Groasis Waterboxx acts as a self refilling water battery for trees.  It collects condensation and rain water, stores it, and slowly releases it to the roots of a growing tree sapling. The method in which the water is released forms a water column beneath the Waterboxx, inducing the tree to grow deep roots that withstand future periods of drought.  You can see Waterboxx results below.  

Thirteen months' growth of a white teak tree in the desert of Ecuador - truly incredible growth without watering and with the Waterboxx

Three years' growth of a salt cedar (invasive in the U.S.) tree with the Groasis Waterboxx in the Sahara Desert!  These trees had over 88% survival with no watering after planting when the Waterboxx was used.
Image from Groasis.com
Two years' growth of a sequoia from planting with the Waterboxx in central Indiana.  No water was given to this tree after planting with the Waterboxx, even after Waterboxx removal.  The sequoia grew surprisingly well, and could easily be planted throughout the eastern U.S. with the Waterboxx.  

If you live in a part of the U.S. with near average or above average rain (25 or more inches), have you considered planting a sequoia or other large tree on your property?  If you live in an arid part of the country, have you considered enriching your land, providing shade and sequestering carbon dioxide by planting desert-adapted trees.  This is now possible with the Waterboxx.  What is more, trees planted with the Waterboxx can be affordable, bare root trees, enabling large numbers to be planted.  The Waterboxx itself is reusable for up to 10 years.     

Wouldn't it be rewarding to leave your land better than you found it, while taking action on the biggest environmental issue of human history?

Sequoia Progress in Indiana with the Groasis Waterboxx




We have always been interested in big trees, and have planted several (4) Giant Sequoias (Sequoiadendron giganteum) outside where we live in Indiana, only to see all of them die.  When we started Dew Harvest® LLC, we decided to use one Groasis Waterboxx to plant a Giant Sequoia, hoping that the Waterboxx would overcome the dry Indiana summers that killed my previous 4 trees.  The Sequoia is very water loving, and does not tolerate long periods of drought.  Below you see pictures of both the Sequoia immediately after planting in mid May and progress since then 6 weeks later (for reference, the lid of the Waterboxx is 20 inches in diameter).

The Sequoia seen laterally at initial planting (again approximately 2 years old).  Some brown is evident from winter die back.

Sequoia after 6 weeks growth with the Waterboxx (almost doubled in size) while the grass around the Sequoia has died back from lack of rain.  No water was added to the Waterboxx except that added by dew and rain naturally.  Note: Orientation of photo is flipped 180 degrees as evidenced by blue cap in Waterboxx lid position.  The lighter blue green color is indicative of new growth.

The Sequoia after 6 weeks with the Waterboxx (approximately doubled in size in 6 weeks, after 2  years of slow growth).  Again, the  grass around the Groasis Waterboxx is dying back from lack of consistent rainfall.  Again, the lighter blue green is new growth, and no brown is evident.
The Sequoia after approximately 2 months, continues growing in height as well as width.  The large amount of light green indicates the rate at which the tree is growing.  The box will be left on over winter, as it provides a blanket of water which will only slowly change temperatures and protect the base of the Sequoia from drying out.  The design of the Waterboxx means that it will not break when the water in it freezes, but may loosen the lid (the ice will expand upward, not outward).



Sequoia after approximately 2 months of growth with the Waterboxx and no external watering (no water has been added to the box except dew and rain, which have kept the box completely full).  You can see that the surrounding grass continues to die back from lack of water, but the irrigating and cooling effects of the Waterboxx keep the sequoia growing without any browning.  This tree will soon be able to grow on its own, but we will leave the Waterboxx on it over winter to prevent the drying winter winds from killing the young tree.


The water level is only down approximately 1 cm (in a ~25 cm high basin) after one whole month with less than 1 inch of rainfall.  The morning dew is funneled into the basin, and this prevents the basin from emptying even though it continues to water the healthy growing tree (Photo from August 28,2013)



The Sequioa 3 months after initial planting with the Waterboxx.  The tree remains green even though the surrounding grass has died from lack of rainfall.  

Besides a very dry summer, we had the harshest winter in living memory.  Just as the Waterboxx provides consistent sustaining water in the summer drought, its basin protects the trunk of the tree from drying winds.  The image below shows the Waterboxx on January 10, 2014, during the Polar Vortex (with temps down to -13 degrees Fahrenheit).  




As you can see, the Waterboxx is wonderfully effective at growing water loving trees (or trees in dry areas) even if there is not enough water to sustain such plants as grass.  The Waterboxx accomplishes this by storing dew, collected almost every night, in its basin and slowly releasing it through a wick into the soil below.  The basin serves as a type of plastic mulch, preventing evaporation of the water during the day.  The Waterboxx will need to be removed before the Sequoia is too large to fit through the central opening, which will likely be next spring.  The Waterboxx can stay around the tree overwinter, and will not break if the water inside it freezes.  In this way, it will also form a blanket for the Sequoia, which is susceptible to drying winds (most experts advise burying the Sequoia in straw in the winter). 


The images above show the health, size, and continuing growth of the Sequoia in the late spring, approximately one month following removal of the Waterboxx.  The Sequoia generally browns out in early spring (see brown above) only to add significant new growth later that same season.  The Sequoia is now ~2 feet tall (23 inches) and about 20 inches wide in this photo.




This photo was taken on July 18, 2014, 3 months after Waterboxx removal.  This Sequoia has not had any irrigation or artificial watering of any type (it did have a pan around it, not shown in this picture, to funnel water to the base).  It is now almost 30 inches wide and about as tall.  It clearly will survive now due to the deep Waterboxx induced roots.  




The Sequoia is seen above on October 4, 2014.  Here you can see it is over one yard tall now (about 38 inches in total height.  It has continued to have new growth throughout the late summer. 

The tree, of course, continued to grow, all without any manual watering.  Below, we show it in September, 2016.   The browning of the lower limbs is normal - lower limbs die off as they receive less sunlight.  This tree has less sunlight than most as it has a fence immediately to its south.



Growing up in Indiana (where the tallest tree is rarely 100 feet tall), we became intrigued with the idea of Sequoias that can grow 300 feet tall and live for thousands of years.  We were disappointed with our consistent failure to establish one of these trees - until we tried the Waterboxx.  We now hope to be able to establish small woods with Sequoias, sequestering carbon and adding incredible beauty to our Hoosier landscape.  

Be the first in your area to start growing trees (including perhaps Sequoias) with the Groasis Waterboxx. As always, you can learn more about the Groasis Waterboxx and buy one (or several) at Dew Harvest® LLC.

Sequoia From Planting Through Growth

Since we were a child, giant sequoia trees have held a great fascination for us.  Several years ago, we saw some giant sequoia trees in small containers at our local botanical garden, and decided to try to grow them.  They grew fairly well potted inside our apartment, but each and every one died during transplanting outside.  Even with frequent watering, the roots seemed to dry out and we were left with a dead tree.  This continued for several unsuccessful attempts, that is until we planted our first tree with a device we read about online - the Groasis Waterboxx PlantCocoon.  We planted this tree with the Waterboxx, watered it once, and never watered it again.  The tree not only survived, but thrived, and is now growing without the Waterboxx or any other intervention.  

We wanted to make sure this success wasn't a fluke, so decided to plant another sequoia, this time somewhat farther to the south, and transplanted at an earlier age.  Below, you can see the results of this test planting.  

The following photos will document the whole growth of a sequoia from its initial planting outside to removal of the Waterboxx.

A small sequoia barely sticks out of  the central opening of the Waterboxx on July 3, 2013, the day of its planting.

The same sequoia on August 24, 2013.  Already after 6 weeks you can see significant growth with even the limited light reaching the central opening.  It has not rained for approximately 2 weeks as of this photo.   

As the sequoia was so small initially, it had a great deal of trouble getting enough sunlight for rapid growth.  However, as more of the sequoia needles reached above the Waterboxx lid, the sequoia began to grow more rapidly.  Remember, we never added any water to the sequoia or the Waterboxx after planting.

Here you see the approximately doubled in size Sequoia on September 7, 2014 (with some dried grass on the Waterboxx lid).
The same sequoia on August 13, 2015.  This tree has dramatically filled out, and we will be able to remove the Waterboxx PlantCocoon after the winter.  The tree will then be able to grow without watering due to its deep, Waterboxx induced root system.


3 Years' growth of a sequoia - from tiny sapling to 2 foot tall tree - no water was ever given to the tree and the Waterboxx was left in place over winter.  

As long as the central dumbbell shaped opening is oriented along an East-West Axis, then the seed or small tree will get enough light to grow.  The Waterboxx cost 7 million dollars to develop, and works so well because of its multiple ingenious features.  It funnels dew into the central basin, and then allows that to drip to the roots of  a growing plant.  You can buy the Groasis Waterboxx PlantCocoon here..  We buy our giant sequoias from Giant-Sequoia.com.  We would love to hear your comments below - to leave one, please click on "Comments".

Growing Melons With Almost No Watering

Home grown melons are one of nature's most delectable foods.  There is nothing quite like a cantaloupe that has gotten so ripe that it has fallen off the vine.  Homegrown watermelons too are delicious, but as all seeds are concentrated in the center of cantaloupe, they are much easier to deseed and enjoy than homegrown Watermelon.  Melons, however,  require a huge amount of watering, and therefore work - deterring most people from growing them.  This shouldn't be the case.

We must admit that after three tries at growing melons, in our raised bed/Square Foot Garden, we were about through.  We would get at most one to two melons, but this required watering every other day.  We did at least find our favorite varieties, the cantaloupe cultivars "French Hybrid" and "Ambrosia" - two melons that were so sweet right after picking you wanted to forgo all other food.

We finally decided to try growing melons one last time - but this time in a large enough quantity to ensure pollination, and with the Waterboxx to ensure watering.

Pollination is obviously vital for melons - if you don't have at least two different melon plants of each variety, it is unlikely you will get a particularly large crop.  Bees should be encouraged(we also bought blue orchard mason bees which promptly flew away but did sometimes return).

To ensure watering, we used a brilliant invention called the Waterboxx.  The Groasis Waterboxx PlantCocoon, or Waterboxx for short, is a device for watering trees and garden plants.  It collects and stores rain, dew and other condensation and slowly delivers it to the roots of a growing plant.  In many climates with regular rainfall throughout the summer, the Waterboxx never needs to be refilled.  In drier climates (of the southwest, for example), the Waterboxx needs only to be refilled every week, at most, with 4 gallons.

A cutaway schematic of the Waterboxx showing function - water is collected by the tan lid, funneled down the siphons shown in red, stored in the green reservoir, and slowly delivered via the white wick.  Soil evaporation is blocked by the Waterboxx basin, providing a consistent moist but not muddy environment for the roots of the plant.  Image from Groasis.com

We first decided which melons we wanted to plant - we chose three varieties of cantaloupe and one variety of (seeded) watermelon.  We then prepared a space for these - two full 4x4 foot raised beds, without any overlying trellis.  Melons have very large space requirements - we satisfied this by having a string trellis at the north side of our two beds for some room for growth.  In the second bed, we built an "A" frame for a string trellis.  We also cleared a large section of grass and covered it with weed cloth for the melon leaves to spread out.  This provided us sufficient room (although the melons did somewhat climb our trellis fence).

8 Melons in 4 Waterboxxes with our A Frame support - the area behind the Waterboxxes was also covered with weed cloth to allow growth..  Here you can already see the size difference between the indoor started (left) and outdoor started (right) melons.
With most cucurbits, it is better to start the seeds outside but we have a relatively short growing season, so we decided to try both indoor and outdoor starting. The indoor seeds we started in peat pots two weeks before outdoor planting.  We must say, the indoor started seeds did much better than the outdoor ones.  The outdoor started plants were quickly overrun by ants - who seemed to grow their colony (and aphid livestock) faster than our melons grew.  Our indoor started seeds, when transplanted whole with the peat pot still in place, grew much faster than the ants and were not seriously bothered by them.

Our melons growing quite well mid summer - we did refill the the two Waterboxxes on left once during a dry spell - right after which we received ~4 inches of rain which would have completely refilled them without our intervention.

We placed two plants per Waterboxx.  We then carefully placed the Waterboxx, making sure we had two wicks in each.  After that, there was little to do beside train the vines of the melons to stay off the paths and on the string trellis where we wanted them.  We did fill 2 of the 8 Waterboxxes with more water one time - and then immediately regretted this decision.  Right after the manual filling we received 4 inches of rain in just a few days - enough to refill the Waterboxxes completely.  We are based in Indiana - some areas without consistent rainfall will need periodic refilling (likely every 2-3 weeks).
Our A Frame and string trellis is completely covered with the vines of the melons.  

By mid July we knew our harvest was almost ready.  The great thing about growing cantaloupe on trellises is that they will fall off when ripe - the gardener just needs to check the ground daily for fallen melons and take them inside.

5 "French Hybrid" melons hanging on the inside of the A Frame with the Waterboxx just barely visible.  

Ripe melons will also change colors from green to tan .  It is important to check the garden every day for newly ripened melons because ants and soil organisms also want the sweet melons and can get through the outer skin in about 24 hours.

Here is a single day's harvest of melons from a 4x4 foot bed of Waterboxxes growing melons - with no water manually added for months.  

At its height, our Waterboxx melon garden was giving us 5 (5!) fresh melons per day.  We found we could only eat one to two so family and friends also received Waterboxx melons.

We didn't forget about the Watermelon - grown without any hand, can or hose watering after Waterboxx set up - the scale reads 19.8 lbs

After almost giving up on melon growing, we found that the Waterboxx brought us profound success.  We plan to continue growing melons each year with the Waterboxx - of course rotating the area where we grow them and replenishing the soil with compost yearly.  If you want to try to grow melons with the Waterboxx, you can buy the Waterboxx here or learn more on our website.  The Waterboxx can also be used to grow tomatoes, peppers, zucchini, squash, pumpkins, and eggplants.

We will be releasing our E-Book, The Waterboxx Gardener on Amazon.com February 2017 which will provide detailed instructions about how to garden with the Waterboxx.

Gardens for Elderly Family Members

One of the problems family members face when older is limited mobility and dexterity. This can lead to a large number of problems.  One of these is a decrease in the variety and health of their diet.  If people are not able to drive to get fresh vegetables, and no longer able to grow things themselves due to arthritic problems of the legs, knees, and hands.  While medicine has certainly improved over the last 20 years for older people, nutrition most definitely has not.

Is there any way for children or grandchildren to improve the nutrition of their older friends and relatives?  Yes, there is - setting up a small garden with the Groasis Waterboxx.

The Groasis Waterboxx is a self refilling water battery for plants.  It is a device that, without electricity or running water, collects dew and rainwater and funnels it to the roots of growing plants.  The Waterboxx also surrounds garden plants (and trees) and protects their root zone from competition from weeds.  In this way, the Waterboxx eliminates most of the work of gardening.




Image 1: A schematic cutaway view of the Waterboxx - rain, dew, and other condensation are captured by the tan lid, funneled to the siphons shown in red, stored by the ~4 gallon reservoir shown in green, a slowly released as needed by the white wick to the roots of the plants (shown in yellow) - photo courtesy of Groasis.com
Only small areas are needed for Waterboxx growing - the side of a deck or a few sunny feet next to the house.  It is possible to set up the Waterboxx in a few minutes, and a raised bed takes about 30 minutes to assemble, depending upon experience.  We do recommend a raised bed garden as this elminates all tilling each spring and won't be invaded by grass.

Follow our steps to setting up a small garden for a family member below:


  1. Confirm that the family member would like to have such a garden and find out if their plant selections grows well with the Waterboxx
    1. The Waterboxx can be used to grow tomatoes, peppers, zucchini, melons, squash, pumpkins, and eggplants easily, perhaps with some lettuce or other greens in the space between Waterboxxes.  The Waterboxx doesn't fit beans or peas and these would probably need to be watered like a traditional garden.
  2. In the fall or winter, find a spot in the lucky person's yard with at least 8 hours of sun per day that is large enough for at least 1 Waterboxx
    1. The Waterboxx is 16 inches in diameter at bottom - we suggest a raised bed at least 20 inches on a side.  It is best to use more than one Waterboxx (2-4) as less wood framing will be needed per plant.
  3. Get the required non-treated lumber to build a raised bed - for a 4x4 foot bed, two quantity 8 foot 2x6 inch non treated boards will be needed.  Have these cut at the lumber store to be 4 feet long each.
  4. Screw the 4 boards together at their corners, like 4 dogs all running after each other in a circle, so each edge is the same length (see image 2 below)
  5. Attach weed blocking cloth to the bottom of the wood frame - not plastic.  
  6. Fill the frame with 1/3 peat moss, 1/3 vermiculite, and 1/3 potting soil.  Each spring and fall the bed will need fertilizer, preferably in the form of compost
  7. Set empty but assembled Waterboxxes on the soil to determine spacing - snug up against each corner (see image 3 below) and one in the center (for a total of 5 Waterboxxes).  There will be space between each Waterboxx for lettuce or other greens.
    1. Note: We do recommend an extra wick in each Waterboxx for most plants - see instructions when ordering
  8. Plant pre-started plants (either grown yourself or bought) from peat pots - this works well for most plants except squash and pumpkins which need to be direct seeded (see image 4)
  9. Place the evaporation cover carefully around the plants, then place the Waterboxx and fill with water
  10. Let your family member follow the growth of their plants.  They can check the water level in the Waterboxx and add water if their is no rain, usually at most every 2-3 weeks.  In much of the country outside the Southwest, no additional water may be needed except during very dry spells.
  11. Have your family member pick fruits when ripe and enjoy all summer.
  12. At the end of the growing season, remove the wick from the Waterboxx and turn it upside down - it can be stored outside if desired, even in cold climates, if upside down.  
  13. Next spring, insert new wicks into the Waterboxx and repeat steps 7-11, after fertilizing the soil.
Image 2: Put three outdoor (deck) screws into each corner - each board should have three screws in its long end, parallel to it and three screws perpendicular to it. 


Image 3: Use an empty Waterboxx to determine spacing - press it down into moist soil to show the "Figure 8" central opening where plants will be placed.  
Image 4: Plant pre-started plants (eggplants shown here) in each end of the "figure 8" - most Waterboxxes do well with 2 plants and 2 wicks.

If you follow these instructions, and assure that the plants have sufficient room to grow and be supported (especially for vine plants like indeterminate tomatoes, cucumbers, and squash), your family member will soon be enjoying the fruits of your labor.  There are few better gifts to someone who has helped nurture and support you.  Get grandchildren involved for a special treat.

Cucumbers and tomatoes growing in a small Waterboxx garden set up for a family member - no weeding and no watering required all summer.
The Waterboxx is sold in the United States at dewharvest.com.  We recommend buying 5 Waterboxxes for a 4x4 foot garden or 10 if you want your only personal garden plot as well.

We would love to hear your comments below, especially of any family members helped by their Waterboxx garden.

Plant Transpiration

Humans have a process through which they release water in their blood vessels to the air around them - called perspiration.  Plants have a similar system, where water drawn up from the soil is released through stoma - called transpiration.

Transpiration is very important in plants, as it one of the processes that allows lifting of water from the soil up the vasculature of the plant (the xylem).  Without transpiration, neither water nor other nutrients would be lifted to the canopy of the tree where they are needed.
Clouds formed by transpiration over the Amazon Rain Forest - from Wikipedia/USGS

Transpiration is a reason why areas with heavy vegetation (forests) tend to be more humid than regions with little vegetation (deserts).  Transpiration can be significant enough to contribute to rainfall.  Transpiration is also tightly regulated, higher in low relative humidity, and higher on warmer days and in higher wind speeds.


Because transpiration is an invisible process, a simple demonstration can help convince yourself that this process is taking place.  Below you see images of an indoor jade plant (Crassula ovata).  This plant is then watered, and has one of its branches covered with a clear plastic bag.  The jade plant is then placed outside on a warm, sunny day.  The bag quickly fills with droplets of water.  This is transpiration in action.





While plants do have a system to regulate how much water they transpire, slowing of transpiration slows the growth of the plant.  This is why a consistent water supply to the roots of the plant is important.  The Groasis Waterboxx is the best way to ensure this consistent supply of water.


A cut away view of the Waterboxx - showing how water is stored, and funneled through a wick to the roots of a growing plant - from Groasis.com 

The Groasis Waterboxx is a self-refilling water battery that provides a consistent source of water to a growing plant.  The Waterboxx contains a water reservoir, filled only once (at setup).  The water is then slowly released through a wick in the base of the Waterboxx, around 50 mL (10 teaspoons) of water per day.  Daily dew and occasional rain refill the Waterboxx.  Because the Groasis Waterboxx delivers water to the growing plant every day, the plant can remain metabolically active and growing, not dependent on irregular rainfall.  The Waterboxx can be removed after about one year and used again.  The Waterboxx can be bought from Dew Harvest in the United States.
