I'm thinking about getting a procyon-100 for a 4x4 veg room. How well do these work compared to a 400 watt MH in the same space? It seems like it'd be cheaper: less heat so I don't have to run my a/c, less electricity (my pge bill was 260 last month), less vents, no hood, no ballast, etc... so it looks like the room will cost about 800: 600 for the light and 200 for the closet.

i would take that 600 bucks and instead of the led, i would get a 600w or even a 400w digital switchable ballast with an aircooled hood and a nice vortex or valueline inline fan and save some money or break even but get more yield in the end.
i realize your concerned about electricity useage but a 400 watt and an inline fan wont raise the bill by that much compared to the finished product.

well if you dont want have to vent and dont mind spending the extra fro the led then i would go with the led for veg only since it uses less energy and u dont have to air cool and then you dont have to cut holes anywhere and therere isnt the loud noise of a inline fan or if you want a happy medium go with som hi t5s

hi guys, i am new in the forum but an expert in DIY. i have read many LED vs HPS . so please read carefully my calculatios. and make your own decisions
example:
ordinary 600w Max-Lumens SHP-TS HPS 600W : 90000 (lm)
25 euro ebay only the lamp
versus
one of the best brand name LED available. not some chinese ones that claim only llumens
Cree MC-E Emitter white - BIN MCE4WT-A2-0000-000KA1 Luminous flux by connecting all 4 chips in series:
min. 280 lm at 350mA
max. 490 lm at 700mA
basicaly for you to understand a 5w led emits depending from the current 100-to 240 lumens. this one is 4 leds in one
its one of the brightest available
here is link with more datahttp://www.dotlight.de/products/en/LEDs/LED-High-Power/CREE-LEDs/Cree-Emitter-LEDs/Cree-MC-E-Emitter-warmwhite-max-490-Lumen.html
and don't be fooled. power means heat and this heat should be dissipitated somwhere. this with the cool led light is a fiction.
look what they say for that led
Please ensure a sufficient cooling !
This LED can only be operated with an additional heat sink
Caution: The MCPCB can get very hot (~70 °C).
Device failure caused by overheating voids warranty
so, do you understand. if it makes real lumens it makes heat even if its LED. and if it doesnt make heat it doesnt make lumens and it is a scam
ok. lets calculate how many Leds we need to make equivalent of 90000 lumens. we asume that The brand led can make 500 lumens though it makes less. so
90000/500=180 Led x19euro=
3420euro
even if you get them at discount half price its still a lot of money and it needs to be powered by sth.
and this is the best case. the 5w Led which they have in the necessary wave spectre produces 100-250lumens
i wrote this calculation cause i did not see it any where in internet and i believe it would be usefull for you to decide Led or no
even if i am wrong and there are ssome even better Leds they would not be far more better so the answer is the same.

If you want to go with LEDs look into building your own it'll be a hell of alot cheaper and you can use newer technologies (Procyons have been around a couple years) Also don't buy into the manufacturers claims of HID equivalency, sure LEDs are more efficient in energy when used correctly, but hardly 3-4x as efficient. Maybe 2x if your using them as efficiently as possible (spaced out correctly, close as possible to your plants.)
But by all means join the rest of us in testing out LEDs for the future. There will always be naysayers no matter what you do when it comes to new ideas, they'd rather just sit back and ridicule the technology until it becomes viable and then just hop on the bandwagon. Decades ago when growers headed indoors for the 1st time, there had to be plenty of people saying the same things then. Similarly even more recently within our own decade CFL growers went through the same. Without pioneers trying out new things then nothing ever changes, so if you do decide to go with LEDs in whatever setup I commend you!

I think your math would apply more if luminosity effected plant growth that much but it really doesn't.... For example your normal 42w CFL produces 65000 lux when hung about 4-6in above your plant. Go to this link http://www.creatiesintechniek.nl/Led/test2.html his setup is 60w and he hangs it 2 feet above (very inefficient imo) and it produces only 5000 lux at the plants (as shown in the photo at bottom of page) but he still ends up producing 53g. And before you go criticizing the time period like others have read the dates accurately I know its confusing as hell but basically 2.5 weeks vegging 9 weeks flowering. That journal is a year old too, and hes only using 2w bulbs.

buy a 600 watt hps air cooled hood and fan, dont try unproven crap. If you can buy T5 for vegging, amazing resultsView attachment 354099 without hi electric bills.

LMFAO ROLF spat my stella artois an the screen! unless you know what the fuck you are talking about then please shut up!
i bet you are a paper grower in other words you look at a pice of paper and say this will be better, but never grow fuxk all in practice!
LED is a waste of time! show me one picture where a cannabis plant looks good grown under LED? there are none thats why! LED growers start serching google untill you die you wil not find onel

Like I said in the other thread where you ended up bashing me, I just link that journal because it proves LEDs can be viable and as I said its all experimental up til now and alot of the earlier applications are pieces of shit and have given the entire concept of LEDs a bad image. Up til now I have done a small indoor grow a year or so ago but a family member came to live with me for a bit and I had to shut down operations. Now that I'm able to again I want to eperiment with LEDs in different applications for growing. I have 17 LEDs coming in the mail 15 3w reds 2 3w blues 51w total, should arrive Monday. Going to try some interesting applications using those 51 watts to grow my single Super Skunk Fem seedling I have sprouting under a CFL for now until the LEDs come and I get them setup. As I said its all experimental but if you don't want any part of it just stick with your HPS and don't bash the subject everytime you can.

HAHA ROLF 51w what are you trying to grow? how much did that set you back? i could get a 2 x 20w CFL for $2 that will yeild more! look you can give a plant all the correct light spectrum of light you like it will not grow with out the light intensity!
you may as well grow outside in the shade! and that will cost you less than any bulb to run, cannabis loves strong sun light - unshaded light is the best light avalble today from a HPS light.
untill LED light can produce anywhere near the intenasty of a HID then dont buy one! no matter what the correct color spectrum!
LED is like trying to grow cannabis under a big tree that has no light geting to the plant, its just to weak! you could use 1000w of LED it will not come close to a 1000w HID!

im under a 400 hps sun supply 2 and a home depot special 100 watt hps and i dont have jack shit for heat. as a matter of fact i need a heater in there because the hps doesnt throw enough heat to keep it warm....but i heard those ufos are bad ass. they look kool too. im still a fan of the big hps though. i do have a fan blowing to strengthen stems but thats it. do some hps lamps give off a ton of heat?

rule of thumb use more light (more wattage) save on elecrtic and grow more bud after all if you need t use a heater thats wasted light that you can get from the bigger HPS. i.e if it coold use a 600w and not a 400w.
i hear a lot about cooling the grow room and how much you will save if you grow under CFL or LED's here is what works well when you grow under HPS = the air in a grow room needs to be exchanges at least 30 x per hour to keep the co2 at around the minimum to suport plant growth to the maximum, so that extra 50w of power to cool 1000w HPS is like using co2.
Co2 is no use unless you have the perfect environment i.e temps humidity and correct nutes unless everything is spot o Co2 is a waste!! sorry to all you home brewers who thing you are getting more yeild than you would with out it the truth is you aint!!!! and would do better with more air exchange than trying to keep co2 in the room!.
LED lights are a joke when it comes down to growing cannabis.
show me evidance thats all i ask????

and? its shit! the bud he is trimming is not grown under LED i can tell you that! LOL look at is plants! he is selling the clipper and trying to sell shit LED's
look if LED's work'ed i would use them they dont so i dont use them- simple as that. I hope one day they will, but wait un till then dont waste money on them.

HPS light makers have nothing to prove we can see it grows fantastick buds. LED light makers cant show anything other than what should work on a pice of paper! wake up fools!!

Have you tried growing with actual High Intensity LEDs like seriously you've made it your personal goal to spend 10 posts in each thread bashing them, we've given you 2 examples where they clearly produce just fine and you just ignore them. I spent $65 for the LEDs with shipping I sent the company an email telling them I wanted to test it out for growing applications and if I could get any kind of deal and they sold them to me 50% off. I understand since your like 12 9inch $65 might seem like alot of money but like I said I want to experiment with them because most likely in 5 years they will be replacing everyones HID lighting just because there cheaper and more cost efficient, and by that time probably a hell of alot better. Because of the way technology evolves exponentially driving down the costs of older equipment as it does so and as that evolution continues the older cheaper equipment becomes better and better so that say in 5 years from now you can get a 25w diode for only $5 you make an array of 100 of them and you have yourself 2500w of light in the perfect spectrums for growth for only $500

i have never used LED's to grow with. ive have a couple of LED flashlights, worthless pieces of junk. maybe in a few years from now they will be better. i just cant see where an LED if going to give the light penetration that an HID gives you. i paid 40 bucks or less for my 400 watt HPS fixtures brand new. they are industrial fixtures, low bay lights that i made remote. i wouldnt trade these in for anything except a 600 or 1000 watt HPS or a digital ballast. but for the price of the digital i can get a bunch of these lights.
e-bay do a search for crescent light fixture. i beleive there is only a couple of these left and the seller puts up 1 a week for auction.
the link in my sig. will show you how to make this fixture remote. it is a magnetic ballast but for under 40 bucks it was to hard to pass up.

right, that's what you can do with a 62watt LED.
