Bringing fresh air in for a co2 is actually a bad thing sort of. With co2 the room has to be sealed and levels have to saty around 15000 ppm while lights are on. You can do timed air exchanges but only like 3 in a 12 hours lights on period. I use timed fans and dampers that open and close when the fans are on or off. You want the area to keep the co2 in at all times and if you you do something like keep bringing fresh air in the whole time your wasting co2 and not benefiting as you should. You can do like I said 3-4 room clears then make sure those happen right before a new co2 fill of the room and your good.
wat about outdoor plnts ? they have fresh air and "passing" co2 i assumed that cool air with natural co2 levels constantly passing through wud mimick the ideal situ, and must surely be better than no co2 at all? am i wri
ong ?
