right now light out put is week. They are T8 non HO. I am getting only 11,000 lumen. As for Kavin, I have 2 Gro-Lux tubes and 2 4100K for now. I am upgrading to a T5HO 6 lamp in the next few weeks. Also last night before bed I hit the little guys with there first nutrient. I gave them a standard 20/20/20 and gave a half dose. Woke up to them being purple! Pics below:
