Answer for Crystalfengqian

Dear Crystal , in this way you can plant as a minimum 1 tree per year, which is around 10 trees with one waterboxx during its lifetime. This is meant for areas where there is only one planting season, like in California where this speech was. Suppose you use the box to plant corn in Kenya, then you can plant each month 4 plants during 10 years = 480 corn plants. So the numbers depend on the planting place and the seasons that occur there.

One box for one tree for a year,and then another tree.Isn't that too slow?
