How to set up co2!

How do you set up a grow room the is sealed enough for co2 supplementation? Like what exhaust/intake goes where?

anyone have any links?

intake near the bottom and exhast on top; Co2 is heavier than air so it stays close to the ground. I hope that helps bro

To get the most of your co2, you could do a sealed room. It costs more to set up, but will be much easier to dictate the environment. You would need an ac, 4000btu for each 1000w light. Co2 and a dehumidifier. The air is never exhausted, therefore, you will waste a lot less co2. If you're interested google sealed grow rooms, or closed growing environment. If I had the option, I would definetely go sealed.

Black and white poly (also known as panda film) duct tape and two long zips are all you need to create a relatively well sealed grow room.

Use the zippers for the doorway and there shouldn't be much of a problem if your ventilation is good!

I would not suggest using C02 until you know you've completely maxed out your grow room in all areas except of course the C02.

This way you will definitely know if the C02 setup is working for your particular needs.. For example if your setup is 40% of what its total potential is, adding the C02 is only going to boost it up another (say for arguments sake) 20% so that leaves your grow room at 60% efficiency.

Max everything out first and then try the C02. I'm not hating on you OP, i'm just saying don't waste money on a system before you've got everything else dialed in.

Have fun with whatever choice you make though!

ya if your gonna us co2 you def want a sealed room, I have a environmental controller with a co2 ppm meter in it, got my room up to 1500 ppm and then turned the exhaust fan on any my ppm went down to like 500 ppm, u run both at the same time and ur just wasting your co2, if you need to cool your room use a ac

and arrid makes very good sense

but co2 is know to increase everything by at least 30%, but up until i got this controller i didn't realize how much co2 i was wasting. so if your gonna use it, make sure your exhaust is OFF

and if you have an intake fan then you shouldn't need co2

thanks for the info, i have an a/c in the room but it is a portable one that exhausts thru the roof. i wonder if that will waste my co2.

You're gonna want a dual hose ac in a sealed room.

Are you talking about two hoses that blow cold or two that exhaust?

no clue what he is talking about???

Some portable air conditioners have one hot air exhaust hose, and some have two air hoses: one for air intake and one for hot air exhaust. A single-hose unit will take air from the room that it is in, cool it, and return most of that air back into the room. During this process, a small amount of that air will be used to cool the unit and will be subsequently blown out of the air conditioner's exhaust hose. This creates slightly negative pressure within the room being cooled, as a small amount of air is constantly being removed from the room. If this negative pressure is anticipated by drawing unconditioned air into the room from adjacent spaces, then the cooling efficiency is slightly affected.
A dual-hose unit works by taking in air from the outside through one hose and using that air to cool the unit. The hot exhaust air is then expelled through the second hose. This process does not create negative pressure inside the room being cooled. However, there is a tradeoff. Dual-hose units use warmer, unconditioned air to cool their compressors, which results in slightly less efficiency. They also employ two internal fans, which can mean slightly higher energy usage. At this time, we have not seen conclusive evidence that either solution, single- vs. dual-hose, is better than the other when all factors are considered.
