air con and CO2 for enclosed rooms

[gggt]

Hey guys

Im not sure if anyone has any ideas for my problem...

 

Im setting up an underground (cellar) grow and have all the gear ready to go.

 

I realise one of the most important factors in a grow is fresh air. The problem i have is that i dont want to spend considerable dollars and risk potential damage to my house by getting air from outside down into my cellar and back out again. Obviously through two ducts.

 

I have been researching the internet and have noticed a few growers using sealed rooms with air conditioning and CO2 generators to cool and replenish the air.

 

Has anyone used this successfully?

What is the best gear for this situation?

 

My room is 3.5m x 4m and i will be using 3x600W in a 1m x 3m grow area.

Wouldn't you still have to duct the aircon some way? You still need fresh air, and you still have to vent the old...

As far as I know you still need to vent the room ocasionaly, it is not sealed for the entire grow just for regular periods to maximise the CO2 used.

Yeah, the root system still needs oxygen.

 

You will need to ventilate the cellar gggt, no way out of it really.

 

Obviously through two ducts.

No, you are overlooking the door, you can fit an inlet vent into that, if it is big enough and in a secluded place you could run exhaust duct through it as well.

My understanding would be that fresh air going through a cellar would be a good thing?
