Is it okay with 2000w in a 4ft x 7ft room?

[herrjostein]

As the topic say; what do you guys think of a room which is 4 by 7 ft and has 2 x 1000w LEDs? Will it get too hot? I have build a 2 pot RDWC with 8 gallon buckets, (maybe I should make a tutorial?) that i will have in a room that is hidden. (Maybe I should make a tutorial there also?) It is possible to have ventilation directly out the window in the back yard but is not ideal.
I'm also planning to scrog.
This will be my first grow... Of tomatoes...

Thanks for your inputs in advance

i run 3000 in 4x9.

Okay, is that LEDs? Do you vent the room?

Without adequate ventilation you will starve your plants of air. ALL lighting generates a fair amount of heat. Light, water, air, the three things all plants need in abundance.

I run 2x1000 in a 8x8 tent. Temps stay at a constant 78 degrees but I also run a mini split a/c.

As long as you can handle the heat.

Youll probably want to, if possible, run ducting pulling air in from the outside, through a thin duct carbon filter(end cap filter) through both your lights and out the other window/exhaust if possible.

Then run an in room ac and supplement with co2

Or if youre in a more northern state, you could do the same thing but instead of venting the air out the exhaust you can vent it into your room.

This will only work in winter but i do it and it keeps my room/bulb cold and brings in a ton of fresh air. You probably wouldnt need the AC for that but would once the seasons changed.

Ok, the space has little to do with anything. I am running 2000w HID in a 4x8 tent. Great.
However I am running 750cfm Max fan through air cooled hoods and running an AC.

NOW, just because they are LEDs doesn't mean you don't need AC. I would definitely recommend
venting the room out to the back yard. I know how much of a pain in the ass it can be, as the window
I'm venting out is ~8in wide x 21in tall. I had to build a custom manifold to dump the hood air out.

Also, curious as to where exactly you found an exact 1000W LED. I've run LEDs along with HIDs
and have never seen one that DRAWS 1000w. I know there are places that CLAIM their LED will replace
a 400/600/1000w LED but the only ones I know of that are really worth it are the Black Dog LEDs, and
even their Platinum model only DRAWS 750w. Remember, it's the ACTUAL watts drawn that matters. This
is a tricky method with LED companies to make you believe that you're getting a quality product. Even if
you have 1000w worth of LEDs, they can't be driven to their full potential, because efficiency drops off quickly
and heat increases.

If you don't want to vent it, get an AC and run CO2 sealed. Just my 2c.

It really depends on the temp of the air coming in. It's all great to vent air, as long as the air being drawn in is cool enough
to offset the BTUs of your lights. 3.414(BTUs/hour) x (600x2) = 4096.8BTUs heat per hour. The adjust a wings will make cooling
a bit harder as they're not vented hoods and they're an open design. I'd say get an AC, or for now if it's coming up on winter,
pull cool air in from outside. It's harder to control, but cheaper than running an AC, if you can get away with it.
