Can't wait to see what you come up with next. The girls love this stuff. I have only top dressed with it so far but the next homemade 18 gal. Earthbox will be started with 3.0. Keep up the good work Jerramy and don't let the wheels stop turning. I, like you, love to think of new ideas to improve my grow. One thing I will share with you grow family is, I put a 1/4" thick x2" wide board or whatever, under the outside edge of my pots trays that are on the outside edge of the tent to lean them toward the light a little. Water a bit more to the outside to compensate for the tilt. I think this helps get a little more light to those on the outside . GROW ON!
