@dbrn I have been growing a clone under an advertised 35 watt grow light. That plant is now about 12" tall and in need of more light. Still in need of cash, and a desire to invent; I came up with the idea of adding 6 amazon 100 watt leds in a circle around said grow light.
cost lumens watts(@ the wall)
grow light $28 746 25 (advertised 35w)
6 leds $23 8400 77
The Amazon bulbs are 5000K, that’s all that was available. I cut off all but 1/2" of the protective bulb, and plan to line whats left with aluminum air conditioning tape, to act as a reflector and cut down on the annoying glare (it’s in the kitchen).
Measuring with a light meter app, the lux reading averages about 12000 lux, around an 18" concentric circle, 12" below the light.
At first look, $50 for a 100 watt light seems OK, Your thoughts?
