This thread turned into a troll-fest, unfortunately.

Haha, it's all good, it happens. Thanks for clearing things up.
Sorry man but leds are great u just gotta make sure the diode angle, band, wavelength and spectrum are correct. The cheap 14 w led panels use make just more lumens than a cfl only its 95 percent efficient. However those 1w diode do not penetrate canopy well. Use those panels as side lighting where they are within.6 in of the plant and u will see them move along. Or get a UFO. Just not a cheap Chinese one
Off my rocker? For asking a question? Did I insult the grow? Was I rude in any way? I wasn't even reffering to the lights. My question was why would any chem take 84 days? It's a 60 day plant...always has been. I'm growing some Tahoe OG X Chem Dawg right now that finishes in 56 days. My question is related to the strain. Please take your rude comments somewhere else. Many of us have worked to keep this thread polite...which can be difficult with any LED discussion. Then here you come. Thanks.
im with collective on this one, as it is a widely known fact that marijuana receiving the proper amount of light will finish in the desired time with proper dark periods and no light leaks. with marijuana receiving a high amount of light, with proper nutrient regimes, can also shorten the flowering time.My question was why would any chem take 84 days? It's a 60 day plant.
it is ALSO widely known that when a plant, any plant, does not receive the proper amount of light the development of that plant will be slowed, when a 60 day (8-9 week) Strain takes 82 Days (12 weeks....) That is usually a sure sign that the plants are light deficient.
Edit: Major stoner grammar lol.
not if i can do a 42 day flowering time, and get 1G/Watt. im a perpetual SoG Grower, more small plants> few large ones. the main strain i grow finishes in 42 days (6 weeks) 1/2 the flowring time of the 82 days. over those 82 days i Will harvest 2G/Watt compaired to the 1.32G/W you harvested......84 days isn't worth 1.32g/w?
Well I find LED grow lights very interesting. IMO they have a big future and will eventually displace both HID's and CFLs as being both the cheapest and the most effective grow lights. HID's & CFL's are improving too, but there is a limit to what you can get out of that technology. Both HID & CFLs require thin glass envelopes holding a vacum. There's a limit to how cheaply those can be made and the handling expenses reduced. Solid state technology may be expensive to set up but once you have the manufacturing set up, you can crank them out for very little cost.
Right now, it's still early days and they are damn expensive. In a couple of years there will be better units for a lot less money.

Corbat, I was thinking the same thing, but really just wanted to address the rudeness. Also, I'd like to see the pile of buds that added up to 1.34 gms/watt. I'd bet my next harvest that over 50% of those buds were too small and too fluffy to market....but they were still counted.
I used to get around 20% unmarketable buds until I started heavily pruning for quality. Canopys like the one shown in the vid will produce a pile of unmarketable buds. Since I started growing for various collectives, I've had to fine tune my canopy for bud size and density. These buyers are very finicky over what they will purchase. With proper pruning I was able to maintain my yield, but 100% of it is marketable. When I used to grow a very dense SOG ( like the one in the vid), I would end up with too much small/loose stuff...only good for hash and edibles. I'm convinced that LED's still don't have the penetration needed to pump up the lower buds. I do think that they're good enough now to get some good yields with the proper canopy. If I were using LED, I would grow 4 un-topped plants/sq ft to a finished height of around 14". I think that any taller would just produce larfy lower buds. If you look at the plants in my grow op, you'll see 36" plants with golf balls just 6" above the medium.
I guess my point is, I still would like to see a large LED grow totally. This means close up pics of the WHOLE pile. Most underlit gardens can produce some good looking tops. I believe the vid is showing the best buds, and quoting yields from the whole pile. Unfortunately, it takes more than just tops to fill those turkey bags. Your point about low light = long flowering times is well put.
I curious that none of us have brought up induction lighting. I know there are fewer producers, and thus less marketing going around. I've seen the 400's in action and was more impressed by those that any LED I've seen. Has anyone seen any links to some big induction grows????
