Hey guys new indoor grower here and I decided to add co2 even tho this is my first run. I’ve poured my heart and soul into this project and have researched so much and I feel I’m nailing this first grow so I said why not add co2 since I have everything else dialed in. I’ve received my tank and regulator but don’t have my controller/monitor yet. I’ve read up some on how to use the 1200 ppm co2 chart so I think I have it figured out but if anyone had any additional tips on using it just until I get my controller that would be great!! It’s been a tad confusing to me idk why but I haven’t had a lot of time to figure it out either. Do you use a co2 controller or do you use a monitor with a timer to get the results you want?
