Things are looking good.
Another thing I learned on this batch, SOAK the rockwool a few days before, so the water can drain out.
My problem, and did it before, but have better control this time.
The problem is I soak the rockwool, then the clones are drowning in the cubes because they are so wet, and take a week to begin to dry out.
Just gave them water, so they ben drying for over a week, with no water, thus no fresh oxygenated water.
Also as you will see in the video, I added new QB288 lights. There on a 480-1750b, so I need to start with 3 at 3000, and will be buying 2 more, 1 at 4000 and another at 3000, thus will have 5 QB 288 in a 4x4 :)
