10'x10' tent - 5kw?

Thought the 4 x 1000w lights in the tent weren't enough. 40w/square ft. with the 4, seems a little low....

What are yalls' thoughts on adding a 5th 1kw dead center in the tent. This will provide 50w/sq.ft.

Air cooling is still possible, will have to upgrade to a 10" fan because of all the tees...

Aiming for full canopy, 64 plants total. Soil grow... 5 gal bags

Ambient temp outside tent is roughly 62 on average. A bit low but still thinking the heat of 5k in the tent will kick my ass without running exhaust constantly or pretty close. 10" exhaust isn't practical for this as the 8" vortex is only 50cfm less and all the flange sizes for the cool tubes are 8". 747 cfm for a 800 cubic foot room seems fine but not an hvac guy. Trying to insulate the heck out of everything with regards to ducting.

Would like to find something that insulates the metal enclosure for cool tubes.... Trying to get efficiency as high as I can.

Any thoughts on the set-up? I know I started a design for 9x9' tent but have more room than anticipated.

suggest you look at a mixed lighting solution.
Three hps in the center, vertical.
T5s with good reflectors along the walls mounted at an angle to help focus stray light back into the canopy.
Cheap LEDs on top of the plants.

I appreciate the input but hids are only going in there. I'm more concerned with the foot print of the lights providing equal amounts of light throughout. I feel it would work fine but I'm sure someone could chime in some slight modifications or recommendations. I suppose measuring the light intensity throughout the floor would be necessary to determine optimal positioning... a bit much but consistency is key.

i would rotate the intake and exhaust 90 degrees and use a bigger diameter hood in the middle. that way everything gets channeled through that middle hood.

Thanks for the suggestion thre4t2s0ciety. here is the new lay out, also included a complete birds eye view of the tent. luckily in this situation, the gorilla tents can hold all that weight.

This is a closed system. Co2 burner with ducting leading inside, forgot to add the 6" inline that will draw co2 into the room. The carbon filter is at the very top of the tent, the fan sucks air through and ducting is ran from the fan facing downward in the corner. Small oscillating fans are placed in each corner to circulate the heavy co2 off the bottom.

No dehumidifier yet, will put one in when needed. Ambient air outside the tent is relatively cool. There is a 1 ton portable ac and separate dehumidifier within the area if need be. In the winter months, it will be nice not having to use the lighting exhaust fan as much. Condensation on the inside of the tent might show up as the ambient temp drops down to 50s. That's when a dehumidifier inside the tent will have to be running.

Nothing set in stone right now but trying to have everything under controls. The lighting is all on contactors with a timer and relay. Looking for some reliable temperature controlled receptacles. Will be running air cooled lighting fans on temperature controlled receptacles to regulate the fans. Oscillating fans will be running constantly as they are just small fans. First few runs with this set up will be without co2 to get dialed in. Will be looking into co2 controls later.

ur gonna want to vent ur hoods... with a bigger fan then is needed... if u wanna go closed room style there is no way outta using a mini split ac unit...

Was looking at the 12" vortex xl, it's the 2000+ cfm. Anyways was thinking of adding 2 reducers to it. 12" flange to 10" then 10" to 8". The reflectors are all 8". Will add a speed controller if it's too fast. The room size is <800 cubic feet so if anything it will be over kill.

Thought about adding a mini split, didn't want to have to do it unless absolutely necessary. Trying to keep this somewhat stealthy.... and having another unit outside the house draws some attention from neighbors. Was hoping the cooler ambient temperature and exhausting of lights would be sufficient, although I could be wrong. The lighting exhaust fan would be connected to the return duct unless there is a better suggestion. Didn't want to fill the whole area with hot air so it has to go somewhere. There's a 1 ton portable AC in the basement if needed but the temps could be mid 50s if AC running.

What are your thoughts on a split system inside the tent? It can be mounted on the roof supports, having copper lines ran right into the tent kind of sucks.
