I have grown trees in tiny little net pots (less the 3 inch) the key is to be ready for the net pot to break. Basically, the roots are going to get big enough to split the little holes of the net pot. As long as the net pot is "trapped" it should be fine. I just zip tie the net pot to the bucket lid and it works fine for the entire grow.

I just finished a plant that produced 12 O's in a 2 inch net pot actually.

As for hieght, I grow SCROG only. Efficiency is through the roof and I never have to tie them up, plus it keeps plant numbers way down. Check it out. If you go the way you are thinking I really don't have much advice. I have trouble getting the size right for plants done that way. Too much difference from one plant to the next. I am sure someone will have a good idea though.

Good luck
Bachelorpads Reviewed by Bachelorpads on . DWC Bucket Size- Seedlings After starting seedlings in Rapid Rooter, I can't transfer them to my 5 gallon buckets immediately can I? I seem to remember hearing you should start in a smaller bucket while the roots are small, then gradually move to your larger size. Would 3 gallons still be too big? Or should I just get an 8 gallon rubbermaid container with space for 4 net pots, and use this for seedlings, then transfer the net pots to the 5 gallon buckets? Thanks for the help. Rating: 5
