Black Raspberry Kush in Rockwool

It's interesting to note that I usually see light burn on my plants after 6 weeks of flowering. The first six weeks they seem to prefer high levels of light, and then as things start winding down I have to raise and dim the light. It took me a few grows to see this pattern, but I think next time after about 5 weeks of flowering I will raise my light in preparation of the plant needing less. This generation of LED technology is capable of giving plants all they need and more at very low wattages. I built this light to only pull 90 watts from the wall and it can absolutely hit the max amount of photons a plant needs on a 12 hour period in a 2x2 foot space.
