I am new to the forum, and extremely interested in growing with LEDs. I have never cultivated MJ, but plan to grow other things. I am pretty good with electronics and understanding basic electrical theory, and plan to build my own light panel using reliable parts from the net.

My question is, how much is enough?? Personally, for a small home operation, i think a 600w HPS is overkill and a waste of electricity since most of the energy is converted into both unusable spectrum of light and heat.

Leds sound like the right idea given plants only need certain spectrums of light to grow and be healthy.

How much LED power do you really need for a 3-5 plant setup??
