I've seen this exact strain grown under white and deep red leds only with amazing results. Best buds I've ever seen anywhere actually. They were the size of my calf.

They guy made a led fixture using 12 neutral white 3w, 12 deep red 660nm 3w and 4 630nm red 3w. I've never seen buds this nice before. Critical is a good heavy duty strain with big yields.

@anyone,
Could someone please tell me the reason NOT to use multi-chip emitters? I see this talk on here worrying about if a led is single or multi-chip. From everything I've seen a multi-chip emitter will run more efficiently giving you more lumens/W.

There are pure white leds out there that are using 100w 100 chip single led emitters in a dense matrix. They pack a huge punch and people are growing straight up trees with them. Ya know, eventually up the chain, it would not make any sense to have single chip/die emitters in the higher wattage territory. I don't understand why this wouldn't apply for lower wattage leds as well.

Why would a person be worse off to use a 3w 3 chip led vs a single chip 3w led? I just don't get it. The datasheets say the 3w 3chip leds put out more lumens/W.

Could someone please explain what I am missing about this issue?
warrior #113 Reviewed by warrior #113 on . Calling out to Weezard for LED advice My friend, I've read your stuff here and at Steve F.'s site. I want to build a dedicated flowering lamp using Ledengin 15 watters. (4 reds, 1 blue, and possibly 1 warm white; LM 317's so I can tweak the ratios.) Essentially, a copy of your 4+1 cake pan lamp but built on a 4 x 18" finned heatsink so I can see what's going on under it.) If I were to post my picks for power supply, resistor ratings / values, etc., would you critique and perhaps offer some guidance? I have already purchased Rating: 5
