Too late to bump it up to 2600 watts?

[africanherbman1]

Right now I am running 2 air-cooled 1k watt hps over 2 4x4 trays lined up. I also have a 600 watt air cooled w/ elec digi ballast at my disposal. Would it be worth it to line up all 3 lights over the 4x8 space. The room is sealed w/ 2000 ppm of co2 and I'm having problems keeping it in the low 90's for accelerated growth- it stays in the mid 80's as is. I was thinking that I could put the 600 in the middle of the 2 1k watts w/ extra ducting on each side to allow me to drop it closer to the canopy. Im using a 440 cfm cam fan to bring cool air through the lights, and then duct into the attick. I'm 3 weeks into flowering right now. Do you think it's worth it? After writing all of this down, I think it is, but unbiased input is always a plus. Peace.

Ok, let me ask you this; why WOULDNT you?

your 600 will have to be closer to the canopy to get the full lumens. this will create a shadow from your 1ks. it wouldnt hurt to have in there but you would have to keep it at the same distance above the canopy as the 1ks. there will be a benefit though cuz you will have three points of light instead of just two. this helps as long as the 600 doesnt hinder the 1ks. personally i would toss it in there just to illuminate some otherwise shadowed parts of the plant. just keep em at the same height.

hang it at the side shit dont matter hang it vertical on one side it wont be the most effecient set up but it adds light...

You say you cant keep the room warm enough, so why not stop air cooling the lights? You can put them on a thermal relay so they turn on when the room gets to a certain temp. I have one from Home Depot for attic fans.

I went ahead and added the 600 watter. It is insane how much better everything is responding. Instead of having that 30+" of ducting between the 2 1k's, I have the 600 dropped 12" lower to the canopy still being aircooled perfectly. The duct had to be bent, but it wasn't too extreme. The temps are staying perfect right now. Yamaha-The reason why is because I am using an enviromental controller, and am waiting for my extra relays to come in-they're all being used for lights and co2 right now.
