Hello fellow RIU members, I am planning on setting up a 4000w setup in a 10'x10' area. The room will be sealed for climate control. There will be 36 plants total in 7 gal pots, 9 per light. I will be growing organic and will be using the mainlining technique to create a full canopy. I have created a list covering most of the materials I think I will need. Mainly wondering if this is a practical setup, constructive crticism is what I'm looking for here. Your help is much appreciated.

Lighting

(4) 1000w MH bulbs: Ushio
(4) 1000w HPS bulbs: Ushio
(4) 8" XXXL hoods: Sun System
(4) 1000w dimmable ballasts: nano?

Fans

(2) 8" inline fans: vortex? (High Cfm)
(2) blower fans: Laasko
(4) large oscilating fans: Laasko

CO2

(1) controller: Sentinel Cppm-4
(1) regulator: Titan
(1) 50 lb tank

Temp & humidity

(1) controller: Sentinel evc-2
(1) 10,000 BTU AC Unit: ?
(1) dehumidifier: ?

Nutrients, Etc.

• Supersoil mix w/ vermicrop organics
• Drain trays
• Smart Pots
• Gro-Kashi

Bug Prevention

• Imidacloprid
• Spinosad
• Neem/ Azadachtrin

( I have mixed up the supersoil recipe with roots a few times now and have had bug problems, mainly thrips. This is why I have decided to switch to vermicrop organics, which is local. Instead of buying soil that is made in another state. I have seen some good results regarding supersoil w/ vermicrops soils. If anyone has any experience using this soil please let me know.)

Sounds like a fun project. Nice list of equipment too. I'm not organic yet so can't help with that but two things caught my eye.
First are the ballasts. If you're in the valley like me there's a hydro shop in Modesto that has some Solis Tek ballasts for $155. Check out Growershouse.com They have some test videos & one is on digital ballasts. The Solis Tek beat the next best by around 10%, are dimmable and most places sell them for $220 & up. I went with Gavitas but if I was keeping my Raptors I would have bought them. Shoot me a PM if interested & I'll get you their info.
Second is the A/C. Again, if you're in the valley 10k might not cut it. With dehumidifier & a CO2 burner my 24k window banger barely kept up this summer. I'll replace it with a 36k mini split if I keep 6 lights. Can't wait to see how this comes out. Good luck!

Ya my comment was mostly on the heat output being a lot with 4000w. For a 10x10 room thats gonna create a lot of heat, as long as you can temper that hopefully it'd work though. Also I would comment, why get 4 MH and 4 HPS bulbs, instead you should just get one Ceramic Metal Halide, and then you don't have to go back and forth changing bulbs.
