LED or HPS

[Felixthecat]

(grow space is 16x16 warehouse)my friends boss wanted to do a indoor grow opt and this guy has a shit load of money and he don't care about spending the money hes had, so he tells me he wanted the most expensive shit there is in the market(he wants to use LED)
but really i dont know shit about LED but i heard it runs way cooler than hps and you need red and blue lights and all these shit, i was thinking with a fucking 16x16 warehouse it would be too cold cause winter is also coming
So can you guys tell me pros and cons bout LED
and what should i tell this guy to use or what should he use?
thank guys

i know u want people with led experience,but if he has the cash.your not going to find a led lighting system that will over power several 1000 watters and give the same amount of production.and if u have tha cash heat production from those lamps wont make much of a difference with his top of the line ventilation.weezerd has 2 really nice looking led systems that look like they have a great foot print they are the TI smart lamp.type that into your search engine and see what u come up with"not saposed to post links"

I'd search for "Indoor Agriculture"...
Just a hunch...
see my grow logs

If you want the best LED light then go with the Lumigrow ES 330 watts, it is a true 600 watt HPS replacement and can grow some fantastic plants all the way to maturity with no real disadvantages compared to HPS. Uses literally half the juice and only produces a fraction of the heat. Also lasts way way longer. You can get them for $1200 or so each from the company direct (lumigrow.com) and one will effectively cover a 4 x 4 area when they are overlapping or 3 x 3 by itself. So to cover say a 12 ft by 12 ft square area completely you would need 9 of them but potentially could easily more than pay for them with the first crop several times over. Assuming of course this is a legal grow for medical purposes only by licensed caregivers. I'm factoring in empty space for room to move around the garden or through it, airflow and equipment, that's why I'm saying 12 x 12 instead of your total room size. :hippy:

Put a General Hydroponics Eurogrower (the complete version) under each light for 8 big plants x 9 = 72 plants total. At just a mere 1 ounce per plant (plants of like 18" - 24" or so at maturity) that would be minimum 4.5 lbs of flowers per cycle WORST CASE scenario. More likely is 5 - 6 pounds per cycle with good high yielding strains and nutrients (use the 3 part GH Flora series & Lucas formula of 8 ML of micro & 16 ML of bloom during flowering) with just a total of 2,970 watts of LED going and very, very minimal heat.

If you need to ADD some heat get the biggest gas Co2 generator you can get and don't exhaust the air out but I would'nt exceed 1200 - 1500 ppm or so with it which will give you huge yields compared to without..9 of those LED lights will actually add about 15 - 20 degrees or so to the ambient temps Im guessing. Compare that to ONE HPS 1000 that would nearly do the same thing temp wise itself and heat could become a big issue really fast.

Hey there FreeDaHerb,

How good have your results been with the LumiGrow ES? I came across thier web site and was very interested in them. Thier use of 5 watt diodes is what caught my attention, plus the red/blue dials for setting the R/B ratio seems really trick. I would think that for someone using only one light for both veg and flower could find that pretty usefull, almost as good as Weezard's "dial a stretch" control.

Hey oldmac, I wish I could give you some real world results but unfortunately I do not grow and have no plans to anytime soon.
I am however a very keen researcher and have seen & heard only fantastic things about these specific led growlights. I think this is what many of us have been waiting for spectrum wise. Good luck brother, OVERGROW the world! :thumbsup: :hippy: :rastasmoke:

Maybe this will help...I think this calibuddz dude is on 5 weeks flowering here, I think they look damn good for pure LED light and he is growing in soil so with a hydro set-up it would likely be much bigger at this point. (and these plants look great for 5 weeks in soil) The 660 nm peak red with the white LED's does the trick it seems. :stoned::stoned::stoned::stoned::stoned::stoned:

what about this one TI-SmartBar 1000 ProBloom Buy LED Grow Lights, Procyon 100

[FreeDaHerb]

I think those are very good lights, but the much newer Lumigrow ES is brighter with higher power LED's and true 660 nm red...top of the food chain right now. Also, that light you mention the probloom 1000 uses 430 watts total and must be water cooled which I'm guessing is a paint in the butt, also $1900 each! I heard the company that makes them is going out of business anyways and having legal issues. (was in one of the calibuddz threads)

I did not know that thanks for the info
