I thought it would be cool to have a thread where people can document their gpw using LED lighting.

I hope this doesn't turn into a huge LED vs HID debate, but I fear it will...

I realize everyone wants to achieve 1 gram per watt, but when I was growing (with HPS/scrogging) I averaged about .6 grams per watt. The best I ever did was about .85 watts per gram.

I have a WEX-C150 LED unit currently growing jalapenos. I currently can't grow, so I have no personal LED measurements yet (jalapenos it is for now). However, I really expect my 150 watt LED unit to produce about .75 gpw when I get a chance to use it. 12 plants (sog) would only need to produce about 9 grams per plant for that result. I believe that is doable.

Oh well, I do have about six different grow thread links to start the thread off. Before each link I also listed the total wattage and gpw.

So I ask you LED growers to join this thread and let everyone know how your LED grows are producing...




let's see what you all have done with LEDs...

END OF TABLE



EDIT: created table and added all grows to table...

HGL Brand LED units

3 x 5-gallon DWC buckets, 1 plant each
318w LED unit, approx 4oz
approx 0.35g/w

4 x 5-gallon DWC buckets, 1 plant each
318w LED unit, approx 4oz
approx 0.35g/w

1 3x3 ebb+flow table, 6 started, all killed except one due to males or gimps
318w LED + 345w LED (the last 4 weeks I added 2x20w 2ft Fluoros and a single 42w CFL to cover some dead areas). approx 13.5g*
approx 1.18g/w*

*OH MAN MAJOR EDIT: Rives kindly pointed out to me a few errors in my post. I put 13.5g instead of 13.5oz which it should have been. More importantly, the g/w is also wayyyy off. It should not be 1.18g/w, the real g/w would be .57 if calculated using only the LED listed wattage (LED listed power, not actual power draw. Fluoros not counted. 378 grams / 663 total watts = .57 g/w). Quite less impressive numbers, oh well. Thanks Rives!

The change in my methods and equipment, problems I faced during each run and other variables make me think these numbers are completely inconsequential. Before I ran LED I had a 400w HPS, which I also pulled approx 4 oz off of. I could have definitely done things better in every run, I'm still learning though, just trying not to make the same mistake 2 times. If I hit 1.18g/w in that last run I definitely think I could hit 1.3-1.4. I learned a lot from that last run. Pruning lower stuff early is a must for the units I have, since they don't penetrate below the canopy. I should have clipped everything below a certain level, which I didn't, and it meant I ended up with a lot of popcorn bud and sugar trim bait. The LED was able to produce sufficiently large buds on top. Maybe not 1000w or Sun big, but not small.

why do you anticipate such better results from your ebb+flow grow? the added flouros?

do you have a thread of any of these grows?

i really want to see what people are doing with just LEDs, but glad you joined the discussion...

1.13 gpw with only 60w of custom made leds

[GP73LPC]

very nice gpw

I don't think the added fluoros had much to do with it actually. That run the plant got way too big and I had to raise the lights up all the way and move them out a little bit, it left a part in the middle and a corner that were underlit. Neither of my fluoro fixtures could have really lit a significant amount of the canopy, which was probably slightly more than 4x4 in surface area. I think the significantly better yeild that run just came from experience. I was training the plant better, pruning better, being more attentive with the nutes, and it was the first time I was growing from a seed.

i agree that experience in training, pruning, etc... does make a difference.

1.18 gpw is real nice. keep up the good work.

Wet or Dry? I got 100 grams (sans main stem) under a UFO 90 from Sunshine Systems, but dry was only 9 grams. I am sure my grow method had a lot to do with it

hth

[GP73LPC]

100 wet and 9 dry???

that 9 must have been very dry...

Supposedly fluorescent lights do little or nothing for flowering, so I doubt that had much of an impact. My guess is the extra LED was the main factor, in addition to growing experience.
