Ok so i have 4 plants in rockwool, I noticed good growth past week checked the base and seen really white roots about 4 sticking out visibly from just peeling back a little bit. Some even had the little ones coming out that makes it look real hairy or fluffy. Sorry dont know the proper terms. To get to the point what can I do because the plants are in 6"x6" cubes, the next is in a 3 gallon pot that i put a bunch of rockwool in and let it grow out from the smaller cubes. Do i let it go? Just curious on this find today. Any advice would be appreciated.
