2 hysdro stores say totally different things

Ok, so is it better to presure the room and let the air leak out, or, force the air out. I went to 2 different stores today, and one guy said for sure to keep the heat down, suck the air, the other store said,plants like fresh air fill the room and let it leak out, then you only have to run your filter when you start to really smell.

Im so confused. Thanks.

Negative air pressure is what you want, so you're sucking more air out than you blow in. I would recommend not taking anymore advice from the shop that said to use positive air pressure.

I second this advice. Not only does it make heat control easier, it's also pretty much a requirement for odour control.

I say both.

Thank you very much, this is a huge help. This is my third try, I really need to get it right this time. Next question, what about a/c, how do you run a/c if you have 12 inch fan blowing in and out, and burning co2, when does the a/c kick on. Do you shut the fans off to run a/c and co2 at the same time, and once in a while turn them on to blow in fresh air. Thanks again.

This can be correct. It is mostly choice.

People that use co2 hardly change the air at all. Some people with portable A/C put their filter on a timer to stay off every 15 minutes and run it for 5 minutes. This will change the air 3 times every hour and they wont waste the A/C.

Some people will use both at different times of the day. When lights are on they exhaust for 12 hours straight. When lights are off they do the 3 times an hour cleaning for 12 hours.

So yes it can be both. Hope I confused ya

look into the purchase of a climate control

Thanks, i have a box that shuts the fans off, at a set temp, and turns on co2, but i was not sure how to include a/c when the rooms get hot. Thanks.
