Is there a way to create fresh air in a sealed room?
Thanks

are u talking about co2 because co2 will help ya plants grow faster and yeild more only thing is your going have change it ever week or so

• 1/4" O.D. plastic tubing (ice-maker tubing)
• a 1.5L soda bottle
• one or more 500 mL soda bottles
• an inline valve for 1/4" plastic tubing
• two 1/4" tube to 3/8" M adapters
• two 3/8" F couplers
• Teflon tape
• active dry yeast
• sugar
  thats the cheapest way to make co2 u want to hang it above your plants beacause co2 is heavier than air hope this helps.

I do have forced air to the room, a vent in the room.
I can set a 24/7 fan in the duct to the room to pull the air out of the duct work with no back wash.
yes?

I think you're going to have to import the air, either through vent or with tanks of O2 and CO2.... Creating an 18-20% O2 atmosphere with enough Co2 ppm and an abundance of Nitrogen doesn't seem doable. Night time respiration of plants produces co2 but it's not feasibly a self sustaining reaction. Think you'll have to find an intake somehow, but someone else may be able to enlighten us both.

I don't see a problem there, the vent is a blower, yes?

(Any X2/X3 fans out there? :P)

My bud room is all getto and on the cheap. I do have some air flow in and out ,but alas Im sure not enuff. So I sleep with my plants and exchange gasses with them , works for us. And they like it when I read stories to them ...like Grand Canyon , Great Smoky Mountains ,Old Growth Fir Forests ect... its all good.
