How many de 1000 watt gavitas should i run? It calls for at least 32 lights right? How much air conditioning will it require? 15 tons? Or should i run 20 tons ( 4 5ton mini splits) to account for dehumidifier and co2 generator?

Im trying to open up a medical grow in oklahoma and needing to order up the equipment.
Also what is the best rez to use with a 5 ton ×ater chiller? For sure need something insulated. What are people using?

Im trying to run 4 ucdbxl32s

I would say 32 lights is a good bet.

15 tons would do it not counting other heat factors like summer ambient and solar so you also want to account for that. With 4 x 5 ton units you would be safe indeed with the CO2 generators.

Hellz yea. I was looking at 3 5 ton mini split 5 zone heat pumps. Use 14 air handlers in the flower room and 1 in veg.

Another question i have that i came up with earlier is what kind of back up generators are people using? I freaked out when i thought about a breaker flipping while im away or power outage. Wouldnt u need an automatic switch on generator? Thats all it would take to kill em all is a non controllable electricity issue.
Also im thinking of changing to 2 dbxxl32 13 gallon systems instead of the 4 smaller ones. Less plants but bigger so easier to manage.

Natural gas or propane backup generator with an automatic transfer switch is what you want.

14 air handlers is probably overkill and a lot more costly to install.

You think? The m8ni split comes with 5 on the 5 ton unit

I have 4 ton mini's that have one air handler (wall / ceiling mount). Running 15 line sets is a lot of work and more flare fittings to leak. Also more parts to fail.

Still have to construct the flower room. After viewing cch2o specs my room is going to need to be 24x50. Talk about a bitch to build ugh. Especially when ill be doing most labor. Ill take down that far right back wall and use the corner for 2 of the walls. Use 2x6s to frame the other 2 walls at 10' high 24'x50', run 3 steel posts down the center so i can run a 50ft rafter (or whatever they're called) down the center on top of the posts so i can do 12' 2x6s on each side. Since im not sure u can even buy 24' 2x6s. Lol... I am considering changing to 2 ucdbxxl32 13gallon instead so i can do a 16x60. Still tryin to figure it all out. Inside the room will then be sprayed with insulation and install 3 5ton mini split ac units on the roof of building and run lines down into room. Ugh. Long winded reply i kno. Ceiling is 14ft to the steel cross members

Im starting to worry about a single hydro innovations cool coil in each epicenter being enough to control the temp in the systems. Any have any thoughts on that issue? Defiantly need to have everything in order enviroment controlled push button b4 i put a single plant in there.

Sure cant wait until i get to use the whole big area for flower. There is a 12x15 mother room/ clone room. Ill actually veg in the flower room and just switch the lights

How many lights are u running? I was wanting mult8ple air handlers to be able to blow between the light and plant area to cool the lights. U say u have only 2 air handlers?
I would use oscillating wall mount fans to move air between the canopy and lights, less AC handlers means less line sets and less condensate drains. Id get the tonnage with maybe 4 air handlers, one on each wall perhaps. But if you do put 14 air handlers in there I wanna see some pics, that would be freaking cool! (no pun intended)

Ha right super cool. I just thought that 32 1000 w de would be putting off major heat and i was going to have problems. But i guess if they high enough up shouldnt have to worry about burning the girls?

Yeah if you have the ceiling height you can run a commercial grid and let the light hit the plants from all angles. Perhaps even mix some 1000W DE CMH in there for a better spectrum, less heat and save some energy. The CMH will add some UV and thats good for resin production.

What you mean a commercial grid?
