It is an existing building with municipal water and wells, filtered RO. We haven't quite figured out the best option for raising an lowering the LED... Any suggestions? Growing in Cocowow! that is a definite big jump! from "new to the industry" to 6.5k sqft in a flash! looks like you have a lot of work in front of you! good luck with it all!!
are you using an existing building? you might want to have water (you may have it, i just dont see it! - but i am blind and not so bright!)
will the lights be on a mechanical device to raise and lower them? keep in mind, i know nothing, but is it going to be hydro or what?
this is a growing industry and getting in now will allow you to be involved in the forward progress of the industry, and THAT is very exciting!
Alright, I will look into that. I basically spoke with a few HVAC guys that are local and that had done grow installations before and took their advice. Looking for a reliable and cost effective HVAC system that can handle multiple rooms and the ambient temp of Oklahoma.I would probably get a second option on the HVAC. Looks like that operations could run with 40 tons of AC. Make sure he understands the heat load difference with LED's vs HPS. I believe you can get away with 3000 BTU's per light and that includes the load of a dehumidifier in there as well and fans. Also I would not run that many mini splits. I would consider other options maybe an air handler with VAV's.

Yes. We installed emAre you sure about 2700 btu/light?
Yes, that is for 626w LED and I got the info directly from the manufacturer.Are you sure about 2700 btu/light?
To clarify, there are about 170 LEDs running in this build... Along with Dehumidifiers, aux fans, and CO2 generatorsWhere are you located?
If you $ isn't an issue, get as much ac as suggested.
I would run negative pressure in my warehouse flower rooms, but through vented hoods (1k hps)
I was in Denver, and even with HPS's, i got away with 24,000 BTU's per 12 lights rather easily..
The key was getting the hot air out of the grow rooms, than sucked outside via a greenhouse fan. I'd have an 8 inch in line fan every 3 hoods. It would have been nice to have a bit more during 100 degree days, but i never got above 82, or so.
I have most of my pics on an external hard drive, but I can show you how it was done.
If I ever got less than 2 lbs a light, it was a failure.
I'd also have to see how your building looks in person. How tall are the warehouse ceelings, compared to the grow room ceiling?
It's real hard to judge w/out seeing it
I only had 2 tons for that room. It was about a week after flip

We had a load calc done, room by room. Also factoring the flower rooms on/ off every 12 hours.170x2700= 38.25 tons just for the lights if the info is correct
400sq.ft/ton= 16.5tons (rule of thumb numbers
Other equipment =?tons
53 tons is under sized for this application. You need someone to do an actual load calculation on this building with specs on all of the equipment added to it, a load calculation is way cheaper than fucking up sizing equipment and paying the price when the grow is going
