" do you have to lower and raise the lights" is exactly the type of insight I need, I don't know all I personally have evr used is T5, HPS, and Sun. From research it seems as though through veg stage one has light high 18-30 (depending on specific LED) then during flower light can be brought down closer, some have even claimed as low as 10 inches, however the bleaching thing I here so much about has me nervous. What I find intriguing though is they claim that with LED the plant uses much more broader range of the spectrum available to plant. On a side note here's the redo or last bean rather of the WhiteCheese I seemed to have made it over whatever hurdle killed my other 2 ;-)I have to agree, i would let them veg out for another 10-14 days and do and tucking or lst that you can to open up the lower canopy. As for led this is very new to me and something I will be looking into with great interest. The 2 lights you have ordered look great, can I ask with led do you have to lower and raise the lights or are they fixed to the top of your grow area?, its just I have seen some growers with the led stationary with others raising as needed?
All the best
