I am a bit skeptical. The water smart ingredient is a starch-based water absorbent particle. Made by Zeba corp
I would like to see side by side comparisons. If it was that good--they the Scotts treated lawns would not have died out during last year's drought like the rest of the grass in the country.
I don't see how you can make a teaspoon of water do more than a teaspoon of water by absorbing it on a starch granule.
Fertilizer absorbed better? I never had a problem with fertilizer not absorbing.
So it pulls water out of the soil--and then--gives it back? Fine...why is this good? Does their fertilizer contain enough to do any good?
I would like to see some university comparison trials.
