Ive seen a grow using rubber mulch as the netpot medium. They did fine.

Goodluck with your grow!
I'm kinda using rubber mulch i made black cudes of i guess neoprene or something its like cloth&foam had sex and this is what it made but anyways...

I threw my MG all purpose in the garage cause it uses UREA for the Nitrogen and i heard that hydroponics cant access urea... so i'm gonna use the 15-30-15 MG flowering nutes cause its like 6% ammonical N which is higher than anything else... the only downside is that i'll prob have a N deficiency at the same time i'm having a P overdose is there anyway to remove the P from NPK??? lol or i could just start flowering at 2 weeks???
