Hi growers. hope everyone is doing great.
Im looking for advice about using an Air Conditioner unit. any input on this would be greatly apreciated.
Im running a 4 x 4 grow tent that is inside a huge warehouse, so cooling down the whole warehouse is not really an option. i have been using a portable AC unit inside the tent, but in my short experience this creates 2 big problems: Negative pressure and it also takes a lot of space which i need for the plants.
So to solve this, im thinking about buying a mini -split AC unit, and install it inside the tent at the top, and the second part of the unit outside of the tent (but still inside the warehouse, because of the building regulations i cant install it outside the warehouse)
I will also seal the tent and run Co2

So, do anyone of you have done this before?, is there something im not considering? any advice would be golden
Thank you!

this is a lot for just a 4x4 tent. the real question I think is, are you planning on doing a sealed grow? what temps are you hitting? why do you need a/c if you are in a warehouse? I think you can pull this off if the temps are a constant 75-85 degrees with LED lighting, without A/C ; if you can control the humidity. If humiditiy is the real issue, this is why you should go with a sealed room. In that case I'd build a room around the tent to make the area bigger and make that the lung room for the minisplit and dehumidifier and co2 setup.

As for the condenser you will need a pan that drains somewhere for if you end up using heat. The evaporator (head) will need a drain too. I'd also insulate that room

yeah this will battle heat but also raise humidity look into swamp coolers, it is great for arid environments but can cause issues in certain places where it is hot and humid

Thanks for the quick response :)
I am planning to run a sealed tent so i can run co2. The temperature where i live is crazy hot, right now the temperature is 89f for example.
Also i like to drop the temperature the last 2 weeks of flower to preserve the terpenes so definetly need help from an AC unit.

Im considering the idea you propose of building a small room around my grow tent, im gonna check how much would that cost, maybe i can build it cheap.

I know that installing a mini split in the tent is a lot, but would it still work? i mean what would the draw·backs be?
