Chilling A Concrete Slab?

[Owlfarm]

Those are some good points, maybe I'll just keep it simple and chill my nutes solution and exhaust hot air with a big fan like I have been doing.

Hey everybody, I'm in the planning stages of building a new warehouse and I'm thinking of running pex pipe through the concrete slab and running chilled water in it. It would be like a radiant heated floor but backwards. Ill be running undercurrent systems in the warehouse and I'm thinking this would be another way to keep the nute solution temps down, as well as the air temp in flower rooms. Anybody have any experience doing this? Any thoughts on it?

Here is a tried and proven way to heat a slab. Legalett Systems.

Since condensation is a big problem in cooling a slab, here is a way to do it by using washed gravels in a "heat sink" pit below the slab and using the natural 55-degree earth temperature. Slabs only know one thing and that is how to radiate. very passive, in fact the most passive, they only heat or cool what is touching them and it is totally uniform. If it takes 72 hours to heat a 55-degree slab to 75 degrees, it takes exactly 72 hours to lose it back to 55. it's psychics.
