Start of 3rd week and they are now in 4" rookwool blocks as of a few days ago. You can just see the first of the roots to hit the bottom of the block to start air trimming and building a rootmass in the block.
I've dipped the bottom half of the blocks in a solution of formulex
Looking good bud, have a few of these I’ve just started for an outdoor. Your girls are looking healthy. I’ll have to follow along to see how they turn out. Growers love 👊🏾
