Co2 set up

My recommendation is to do some research on why co2 is used to benefit grows. You probably don't need it and waste some bucks if you don't know how-to apply it. Don't wanna sound cocky but if you don't measure the air and co2 in your tent and know the usual size/temperature range in which co2 becomes beneficial I would not recommend to use it. Unless you got too much money 😄✌️

A proper co2 regulator will have a photo sensor in it that only activates the co2 during lights on.. And maintains a consistent steady amount. Bags and bottles or buckets.. (there are a few options now). for smaller tents.. ProC02(bucket), Exhale(bag) and Tnb naturals the enhancer(bottle). The Tnb is basically sugar and water in a 2 liter with a check valve you can make this yourself. and the ProCo2 and exhale are a mass of bio stuff that produces Co2 (slowly at first then peaking).. Bags are lower maintenance but the sugar and yeast method is easier to play with..

It really depends on the space.. Co2 dramatically improves weight when done properly in Conjunction with light... Not about outgrowing anyone it's simple really.... Co2 Regulators and tanks are for large spaces and need to be done properly and with consideration... But you need a lot of light first then Co2 makes a difference.. Without enough light adding co2 doesn't work it's magic.

co2 bag? and what u wanna spray?

I myself dont use it, never needed to, I outgrow just about everyone without ever using it but if I was to use it, it would be during the hottest times in your tent. Cheers

C02 is heavier than air, so I would assume you would have it falling over them with you extraction fan shut down while applying and a fan moving the leaves so they can breathe it up. Cheers friend
