Learning to...just completed my first grow seed to smoke...more then happy with it but I feel if the roots werent so "birds nest" I'd have better uptake...gonna attempt some root trimming this round...any tips advice or suggestions is greatly appreciated!
Sounds very similar to me. My last grow was like yours. Then I saw all these guys running RDWC and wondered how they got roots like that! If you trim the roots back while small (not more than 10% at one time) it promotes more/new side roots to form. I mainly look for the "runner" roots that are out growing the root mass. I trim 1-2 times a week depending on how the roots are growing. Most of the time its like 3-10 root tips not more than an inch or two in length.
I start plans in 4" net pots and that's where all the trimming is done. This was my first plants to trim. They got a little long before transplant to 8" meet pots. Should have kept them trimmed a little more but it's all a learning process. The single plant I posted earlier is one of these before the transplant.
These are the current ones coming up in their 4" pots. They had a bout of root rot but hydrogaurd works wonders. These will get transplanted in the next week or two. Before they flower.
These need to be trimmed in the next day or two. I'll take some before and after photos when I do.
