Hydro or Aeroponic in Greenhouse indoor?

[Colo MMJ]

Have a metal building and have added the clear polypropylene panels for sunlight to come through. the distance from roof panels to floor is 7 feet to 12 feet.

We are doing a test but it gets hot there and veg plants and clones will cook. We will add a roof fan on on of the metal panels and exhaust and maybe some for of A/C for summer.

We are working in soil but may want to move to hydro, DWC or aeroponic. I am wondering if a chiller for the reservoir would help keep the plants cool by keeping the water between 65 and 70 F. Will the chiller also keep the temp at that level in the winter if the room is below 70 deg F.

We are also not sure whether this room will be better for veg or flower.

Finally, does hydro and aero resist spider mites more versus soil? Thanks.

I would try to limit the heat gain from the structure to make it easier to cool. Simply painting the outside white will make a huge difference.Internal insulation should be on the list too.
Hydro/aero doesnt give you immunity to spider mites but its less likely to habour bugs like soil does.
Does the building have a soil or concrete floor?

Concrete. We are painting the metal roof white. Exterior is a lighter color. Also working on roof exhaust fans. Thanks.

burying the reservoirs would help to cool them in addition to chiller.

i've done hempy buckets for tomatos in our outdoors greenhouse

oops. that would be hard in a concrete flloor. cancel that

A chiller will not heat the water per say but a water to water heat pump will. So the walls are metal and your putting panels in? Are the walls going to have panels as well? It's gonna get hot I would think and yup cooling it may be tough, and yes keeping the water cool is key. If you give a bit more info it would help, like size, etc.

Would recommend isolating the buckets that way the water temp is more manageable. you could buy a heater/ cooler unit (example: resun chiller heater). I've done some research last couple of weeks and bought a Chinese ozone generator for just 10 bucks. In theory you could fix almost all diseases with ozone. If you have a problem with spider mites disable exhaust fan and pump ozone in the room this will kill them. You can also pump ozone in the water if you have root rot.

Isolating buckets like 16 buckets separately from each other but the same room? Thanks for tip on Resun.

May I ask where you found Chinese ozone generator? $10 bucks wow! I know people use them to purify water. Don't you have to be pretty careful with them? Thanks.

I found this ozone generator for $84.95? Says it will do 4,000 sq feet (!) but do not stay in the room. I guess you could put it in the room to kill spider mites then leave??

Please note I am not pimping for Amazon. I know spider mites hate high levels of CO2. $85 to have to kill any bug issues during a grow would be sweet. Thanks for the help.

Excessive amounts of ozone will make some nutrients fall out of solution. I'm no expert on it, just read that in a few places.

I'm not really familiar with anyone doing it commercially for any hydroponic crop.

I've used ozone gens in the past. They definitely didn't kill spider mites. I've used more than enough ozone to where it starts damaging plants as well.
