Hey Dudes! Quick update on my SCROG… It looks freaking amazing!
A bit of a Ca deficiency, but super happy.
Regarding CO2 in an unsealed tent. Do it. These plants blew up when I added it. Running an Autopilot CO2 controller at 800 ppm per Scotty’s recommendation. So far my 20# tank has gone 3 weeks. I use a humidistat and thermostat to exhaust at set parameters, and use my basement as my lung room.
If you go this route, set the liters per minute on your CO2 tank really low or you’ll over shoot your goal.
I’ve tried the bags, and the controller is the only way to go when exhausting, as the controller will keep your ppm’s at your set point when the fans kick on.
Happy growing dudes!!
