LEDs or traditional lighting?

[StoneMeadow]

LED in veg rocks all lighting.....a combo of HPS and LED in flower will get the best yield and quality....i've grown with about every combonation from T5/HPS...HPS alone...LED alone....and the HPS/LED will be your best bet....i use 150w LED's on either side of a 600wHPS for 900w total over a 3x3 tray and have been yielding 560-610gr dry....with HPS 600w alone the yield was 330-350 and w/1000w HPS i yielded 400-445gr....w/450w LED i yielded 330-360....those are hard numbers w/same strains and nutes...you can check out my LED runs in the link in my sig :jointsmile:

This is very interesting information...thanks!

1) 2x150w LEDs + 1 600w HPS = 900w: 585/900 = .65 gm per watt yield.

2) 600w HPS alone: 340/600 = .57 gm per watt.

3) 1000w HPS alone: 422.5/1000 = .42 gm per watt.

4) 450w LED alone: 345/450 = .77 gm per watt.

So, LEDs are most efficient, but it's also clear that the more light you throw down on a given area the better. Presumably, right up to the point where you can no longer control the temperature, right?

Thanks again...really good stuff!

StoneMeadow Reviewed by StoneMeadow on 11-07-2010. LEDs or traditional lighting? I am looking to start my first grow and am wondering what would be better to go with. I am looking to be discrete and will be growing in a room that is 12x20. I have looked at multiple light systems and am leaning towards the LEDs. What are the better LEDs on the market and the cheapest place to buy them. All help would be appreciated.:jointsmile: Rating: 5
