Hey V, I guess you got the streach under control. Training is important with 120 degree lens on the LED's. the 90 and 60 degree have no problem with the distance with the better models. Question, when you hit the switch, does this LED shut some off some and turn others on? this is what i have seen in other models that do this including the factory I'm working with. Fan leaves? I have always pinched as nessessary to clear light to lower buds, and always off the bottom. But I can tell you that for every one that has been growing for a long time, there are that many different ideas on what is "right". Do what works for you. Its your contact with your babies.
