I agree!!!! when I pull my plants down the root ball pretty much eats the air stone....its so deep inside the roots I have to cut them to get it out, so im sure they just love it!!!
I just got my final weight and with 18 plants I got 11.5 # ....not to bad but not as good as I was expecting. I changed the bulbs out to see if that can up the yield. ROUND 2 UNDERWAY RIGHT NOW!!
