4x8 LED Setup

Hello,

I am a first time grower looking to setup a grow in a 4x8 space.
The initial setup consists of a six pot ebb and flow system which will be expanded to a twelve pot configuration.
I am thinking two sufficiently powerful LEDs would look and function nicely.
What wattage should I be looking into?

Thank you,
Currently two 432 watt LEDs from HTG seem appropriate.

I would supplement with more light, I think 864watts for such a big space with LEDs is a bit short, I have the same power in 4x5, everything is looking great but I could use some more.

My final setup may well end up being more your size.
Here is my space and the potential shopping cart.

What do you think would be an appropriate pot number here?

I grow 12/12 from seed, and I am new at this. Most would say I use too big of containers but I believe the plants love it this way with the supersoil. I am experimenting with 7-10gallons containers right now with the 12/12 from seed and supersoil... If you were to go this route, I would say 10-12 plants in that space would be great, watering would be a bitch. You could grow less plant, veg em a while, grow them tall so that you can crawl under for watering ... but I really like the way I do it right now, so little maintenance and I am smokin the best weed, it's a great way to grow for impatient people like me. you can look at my journal in my signature, them plants grow to a decent size 12/12 from seed with LEDs/big containers/supersoil

no need for reverse osmosis water filter with supersoil ... I think it's even bad for it, just tap water that sat for 24hours unless the water in your city is shitty.

EDIT: my bad I just realised you do hydroponic!! I can't really help you here!

you'll want to run those LED's in the space, start with two, if u need a third then do it.
try to get your leds to run at 90 degrees without ventilation.
this way you can exhaust about three times and hour, maintain about 85 degree temps (if this is a soil setup, because soil temps will be optimal), and make best use of co2.

two of these LED's should be enough for heat that area up to previous temperatures stated.

if you find the temps are too low you could get another, althought i doubt that small space will need another one (heat based).

i think you could manage it more efficiently with the two lights places length-wise together [ ] [ ] (in the center to allow growth to stretch to the edges of the room), covering about a 3.5 x 6 feet.

this can cover the whole, but you'd probably want three to cover the whole 4x8 room, side by side.

for hydro you'll want lower temps to keep the nutes cooler around 72 without air stones, 78 with air stones.
two lights max in that room for hydro, although brown roots still produce bud...

control the temps.

Are you going to use co2? Personally I like to have my fan blower on 24hrs, always fresh air coming in, I tried homemade co2 before with a fan that would go on a few times every hours but it was a tiny dresser and I was dealing with heat spikes and humidity spikes... don't think the plants liked it.

Thanks for the input.
It is appreciated.
Here is a to scale idea I was playing around with.
The two smallest circles represent an 8' inline/muffler/carb and a CO2 tank.
Not for the claustrophobic but I have a petite girlfriend. Haha
I prefer to stick with LED due to heat/energy signatures.
Think two 432W LED would do the trick here?

Also, saw the Solarstorm 800 in another thread.
Thinking two Solarstorm 400 would do nicely.

How are your going to top off your resevoir?? or are you going to drill a hole and run it outside the room??? yes two 400w solarstorms will kill it in that setup IMO

Running it outside the room seems the way to go here.
A replacement door would be one of the lessee expenses here.

If you happen to know of a good drain/pump solution I am all ears though.

Strain selection fever is creeping again...

Haha,

Thanks!

Everyone know what I am going to recommend. Starting to feel like a broken record. Have you seen my current grow with my Black Dogs? I would say to BD700 and keep your temps below 82 degrees. 85 causes stretchy air buds even with CO2

It's curious you say that because pro source had a promo video of that guy who had thousands of 180W ufos in a factory who said 80-85 to get the photosynthesis up, the light spectrum requires it or something....

PS. I think most LED's work good, your'e just being biased now sidd..

where did you get this info sidd? My room is at 30degrees right now with summer temps,. ... I hope you are wrong! anyhow, if that's the case I guess my winter crop will be better.

Do you own Blackdog?

I'm starting to think so, you're the only one talking about them, and mentioning them many, many times plus also recommending them to people too much.

You do sound like a broken record btw. An annoying record at that.

don't be so anal bud, He likes his toys can you blame him? I dont work for FERO, I have talk to the guy once on the phone, yet I own a few FEROs and I like them and when people ask for opinions I tell them what I like... Own a BMW and you will tell people to get a BMW, own a VOLVO and you will tell people to get a VOLVO . You just gotta go with what make sense for you, as far as I am concern I wouldnt mind owning a BD, only in my opinion FERO has better price for the power/quality/warranty. If the guy was working for BD I doubt that he would have HIDs next to his LEDs

Being I've owned Blackdog, Blackstar, HTG, HGL, and FERO LEDs, I like Fero the best.

My BD LED yielded me crap not to mention some rows of LEDs stopped working, the BS and HTG was no better though the only issue with BS, the purple LED in the middle is making the mylar surface a brown burnt looking color, I'm 1 month past warranty, BS told me I can have $5 USD off "my next purchase" . Fero and HGL are the ones that stood out for me.

Fero was the only LED light I hit 1 gram per watt with.

I like Fero's customer service, Brent is always willing to answer questions and help if he can. He answers emails pretty fast.

I talked to BD on the phone and said "he'd call back", I have some burnt out rows of LEDs on my 288x3 that Cory has yet to acknowledge even after 6 emails and 2 months time. My BD LED is only 9 months old.

Lifetime warranty my ass....

yo so ive been looking into investing in some leds that can cover up to 10x10 area, after doing mad calculations with my personal experience and also based off of other journals ive roamed thru, U WILL NOT BE ABLE TO properly cover a 4x8 area with 864 watts, double that and your golden, MAYBE haha

so far many legit LED growers have named off some quality and some shitty led panels, now its time ffor you too experiment and learn.

i say start with 4x5 with your 864 watt then when your ready, expand.

live and learn homie

Hey EndurOxx,
I would expect your winter harvest to be better. It almost always is for everyone. Temperature effects on cannabis is well understood. Yes 85 degrees speeds up photsynthesis but it also cause stretch in the bud, most people like dense buds, so 78-82 is what many consider ideal. If it is for your own personal stash or for well informed patient you could expect higher weight overall with 85 degrees, just a bit looser bud. I don't mind loose buds the smoke is the same, everyone thinks denser is better though, so 82 degrees is what i shoot for.
