When do i start to using Co2, i have a 4x8 tent. Also not sure what i set PPM at in a 4x8. How is that math figured out?

Thank You! :peace:
 
1200 min, 1500 max imo.
do you have something that can measure co2? ideally you need a regulator and a controller.
start at flower as he said, some people say it causes stretch so you can wait 1-2 weeks in if stretch will be a problem (more vigorous growth for sure).

Perhaps, but I like to give them an advantage when building plant tissue.. Silica + CO2 = stalks the width of a bic lighter and bud clusters the size of your fist.

But I can see the reason to control stretch... I just train..

when you guys use CO2, do you then have to exhaust it outside ?

Yes, my only reason for exhausting to outside is mainly to control temps when lights are on, and it helps with humidity. I'm just using a adjustable temp trigger, Its crude, but it looks like it works via observations and calcuations. I'm just saving up a few bucks for my new iponic 600

True, Co2 will push out air.

I know for a fact that my propane heater comes with a ODS, for the pilot, I assume that high levels of co2 will cause the pilots in both my co2 burner and heater to blow out because they will not be able to support combustion for the pilot, shutting down any co2 production.

Now I have a 3 gas alarm for the space, but it does not cover low o2 or elevated c02.

Co2 is best for unoccupied spaces IMHO.. I prefer more ventilation in spaces where people and plants are growing.
