I have to say that I am very happy with the progress that I am seeing, as well as how well these lights are working. The plants don’t have any major stretching and the node sections are nice and close. I just started to feed them with nutrients but I didn’t follow the instructions. It stated to use 2 Teaspoons per gallon but I went with half of the recommended amount per gallon. I also moved all plants into a double cup setup as well as have them under a 12|12 light scheduled.
