Plants look stunning Dutch! I saw in some video on defoliation that when you're done, you should not be able to see the pots from above. That means no light is getting down to the soil (wasted photons) where it should be getting sucked in by a leaf.
I was going to try to run mothers but realized I just had no room for that! Now I just keep cutting clones as I go and hope a few take.I don’t think I would keep a mother very long if at all
