Should I add Co2?

Hi all!

I have been growing for a long time without co2. Should I add co2 now I have everything dialed in? or is it not worth it???

Is your room fully sealed to utilize co2 properly? Have you maxed out your growth potential? Then it may be a good idea to try out co2.

Do you have a tank or generator setup? Regulator, co2 sniffer/controller or the like?

You have to seal your room and to adjust your setup to deal with the generated heat.
You shouldnt use portable AC because it will take hot air out of the room with the co2.

AVOID AIR LEAKS, once its done correct it may be a good choice
