Customer Results of Gardening with the Groasis Waterboxx

Dew Harvest® has been selling Groasis Waterboxxes for about 18 months currently, and we feel privileged to introduce this technology to the United States, where it has so many uses.  When we ship Waterboxxes to a customer, we encourage them to email us picture results (to  We are now receiving our first testimonials, and these are very encouraging.

Below, you see a customer in Hemet, California who purchased a tomato plant at a local store and planted it with the Waterboxx.  As you can see, the tomato plant not only survived but thrived and increased greatly in size in just one week.
This customer inserted a second wick in the base of the Waterboxx (to deliver more water to the roots of the tomato), and because of this the Waterboxx may need to be refilled with water occasionally, but it will still collect dew and rainwater and store them in the reservoir.  If only one wick is inserted, the Waterboxx will never need to be refilled.  The Waterboxx's design prevents evaporation of the water that has been released.

This customer from Hemet, California did rig up a hanging trellis system above the indeterminate tomatoes because they grew so large they needed more support.  To quote him "With a good tomato harvest, a single Waterboxx has the potential to pay for itself in one growing season".

Of note, tomatoes in particular are much less likely to split because of the consistent 50 mL (10 teaspoons) of water delivered to their roots daily.  Because this customer inserted a second wick into the Waterboxx, the Waterboxx has a net outflow of around 1 gallon per week.  This means the Waterboxx needs to be refilled once a month in the absence of rain.  Of note, this is not necessary with the standard one wick as the Waterboxx will stay in water balance.

The Waterboxx is excellent for growing tomatoes, melons, pumpkins, zucchini, and of course for establishing trees.  What about growing greens.  The same Waterboxx enthusiast as above found an ingenious way to use the water from the Waterboxx for hydrating a whole raised be of greens (34 plants).  It only needed ~3 gallons (or less than one filling) per week of the Waterboxx directly and no overhead watering otherwise.  The gardener is able to enjoy fresh greens daily.

The Groasis Waterboxx was originally designed to let people grow trees, but it can also be used to garden in drought, especially like the one gripping California right now.

Crimson Sweet Watermelon growing with the Groasis Waterboxx PlantCocoon® in late June, 2015.  This Waterboxx only has 3 wicks, and only needs refilling about one a week.  The largest of these watermelon right now is almost 20 lbs and in need of picking.   
Small and large tomatoes in late June with the Waterboxx PlantCocoon®.  This customer has such a long growing season that he can except continued tomato production until early November.  The Waterboxx only needs refilling once per week in his location.
