Finaly I've found a thread I can relate to, I also use the ebb n grow buckets but I haven't been able to fine tune it 100%, I drilled some more holes on the inner buckets because the roots were clogging the holes at the bottom so I made holes on the side of the inner buckets, now the roots come out of those hole too but not enough to clog them.
The only problem I have is something call the claw, I've tried diffrent nutes but always end up with the claw don''t know what causes it.
I water my plants 5 times a day, and I change the rez every 18 days and I flush for 1 day in between.
