I am testing out how much LED light a beautiful baby can handle. I have been stepping up light over the past 2 weeks since i switched to 12/12. day 1 started with 400w cob day 4 added 200watt LED panel day 8 added 150 watt LED panel Day 13 added 120 watt LED panel so far shes thriving. Single plant in 3x3 coco drinking a gallon for breakfast and another gallon and a half for dinner. how much can she handle? I plan on slapping in another 400w cob in a few days once she adjusts to the current level of light. when does light burn set in?
