We are on to week two. I started seeing roots coming through the net pots two days ago on the two plants in the front, it's harder for me to get at the back two due to the tent location and having a small basement. I can really only access the tent from the front, and the way this system works I can't unzip the right side due to the pipe that leads to the res outside of the tent, so I will just let them go for now trusting that we will have roots in the water soon if they aren't there already.
I wanted to keep it stupid simple this grow so I am just using GH Flora Trio for now, with Calimagic to be added eventually since I run RO water. I may add a bloom booster later if things are going well.
