Hi Folks! I'm glad to see the board is back online ... started to have withdrawls!

So I'm setting up my 2nd grow and I've decided to switch from Drip to E&F. I'm using a 3x3 tray and vegging in 6x6x6 rockwool block. My question is, can I grow directly in the RW without a bed of hydroton? I'm trying to avoid using the rocks because it's a pain to prepare and eventually clean.

I realize the roots need room to grow, but is a 6x6x6 RW block enough? If I *have* to use HT, what's the minimum I can get away with in a 3x3 tray? 1 50L bag?

Thanks, and it's great to have the board back!

(BTW, soon I'll finish updating my harvest from my first grow)
