This is my seedlings second day above soil. It is 1.25" tall right now. I had my HLG 260W QB V2 rspec dimmed all the way down but now I have it turned halfway up. The potentiometer has a detent in the middle. You can feel it as you rotate the knob. The light is 24" above the top of the pot. The stem is nice and straight and strong looking. I also see fine white hairs on the stem when I look with a magnifying glass. I turned up the light because I don’t want the plant to get too tall because it is reaching for more light. I am doing 18/6. Thoughts?
