What you’re failing to understand is that you need to be able to accurately measure the amount of co2 in the air. Not just crack a valve and call it good.
But if your environment isn’t sealed, all that shits going to get sucked out of the room, by your exhaust fan.
Then you need to dial in your environment for the added co2. Which includes your lighting and feeding. Since you can run a more aggressive/powerful feed schedule and more intense lighting.
I don’t grow in a sealed environment with co2, but I’m pretty sure there’s a bunch of crap I’m forgetting.
If others felt like a reply is worth the time, they can explain more. ButI have a feeling this thread’s already dead.
Edit: you say your tent is sealed already. So absolutely sealed? No exhaust or intake? Just curious.
