I've got no known increase from the bags and the CO2 system can kill us if we're not careful. There's usually plenty of CO2 in the air or the house you're in. I've seen some smart devices on Amazon but don't need to spend that money. I know what my tent will be at rh and temp from running it for a time. rh up after watering, water when it gets back down around 30. Exhaust and intake gets figured out with time so it can be left alone for a few days depending on water usage. Just keep at er. I've realized you don't have to throw too much money at a plant to get it to produce, unless your looking at going all out. That light is perfect for your tent. Hope this helps and welcome to the forum. Lots of great people here to help with anything.
