I'm a big fan of LEDs. Especially given the power saving options of switching on/off many times a second. I'm not interested in proving LED's can grow the plant, people like david_zap, medved, led-exp have proven this beyond all reasonable doubt (to me) already. But it seems to me LED growing is fraught with problems and is still in its infancy. What i'm looking at is the idea of a combination of lights to maximise the available light in a small grow.. a combination of LED, HPS, MH - small HID bulbs <120w in total. Just using the LEDs to balance out a full spectrum and provide some extra light perhaps under and around a scrog canopy.. i'm thinking about 1w x 100ish or 3w x40ish high power LEDs...

You guys think it'd work? got any advice for me? it seems all the other LED people do LED solely and i want to see what it can do in combination with a reduced wattage of HID - say 120w HID + 100x1w LED, creating a power drain of about 180-200w rather than say a 250-300w HID array on its own..

supplementing HID light with leds will work. by doing so you are redirecting the energy output to a quality of light that produces sugars for the plant which will speed up growth if there wasn't enough of that quality of light to begin with. i recommend mixing the leds with HPS, since HPS results in the biggest buds which is what the led's lack.

Yeah, I'm doing a very small experiment box at the moment, more than likely will scrog it and put the LEDs under and around the canopy with a 70w HPS on top.. look out for my grow diary
