When injecting Co2?

[noobie97]

When you inject supplementary Co2 into a growbox, should it be blown into it from the intake fan? Or should there be lines going into the plants and the
Co2 pointing directly on them?

All fans are normally off and you use a air line with multiple holes ringing around the grow and raised since CO2 is heavier than air.

So when I use CO2 I have to turn the fans off? Or can I just turn them off? My box would get too hot. I heard that since their using CO2 they can stand up to 95 degrees. But it would get hotter than that.

Then you are not setup for CO2. You need the lights on and the exhaust fans off. Set up a oscillaing fan.

I leave all of my all my fans off in the grow room but my lights are cooled from outside the room. I use a cool air reflector and a cool tube reflector connected by a six inch dryerhose with a 449 cfm vortech fan. But if the room is sealed right u can use oscilating fans to circulate. Plus you can break down your dosing schedule so its not dosing for long periods.
