I do not know jack shit about LEDs, but I will comment that the grow shop I visit uses them and they keep them quite a good distance from fully mature pepper and tomato plants. (I dunno, 2 feet? three feet?)
Shovelhandle Reviewed by Shovelhandle on . Progrow 180 - Grow Box - Possible LED Burn. Help! Hi all, long time no see! Just in the middle of setting up my new led grow box. The plan: to make a very small compact unit that could easily be modified. My setup uses storage boxes that can be stacked - if i run out of head room i just add another box! The environment is controlled be by two 12v temperature thermostats - one controls a 12v pc fan, the other a 12 heater. Uber simple uber cheap! The boxes can hold 84lt, I'm currently using two stacked: 1.4ft by 2.25ft by 2.5 ft cubic Rating: 5
