Nabardo My brother lives in 2 miles from Warsaw 1/2 block from the Osage. Enjoyed the read about LED's, what I'm using now is a 100watt equivalent Sylvania LED 6,500 kelvin 1,600 lumen my plants seem to like it. The light is 4-1/2" from the seedlings, I've been using this light for just over a week. I was using a CFL with the same kelvin & lumen as the LED, some have said the growth I've seen in the last week was because I re-potted the plants 2 weeks ago. Maybe so but I thought it was the LED that caused the growth spurt, no matter just glad their growing well, is 4-1/2" okay distance wise? Just don't want to screw things up.
