How to keep humidity up in 5x5x7

I have a humidifier in there I was just trying to bring in fresh air for them so it’s not hot and stale air I get the humidity up to 75% when I’m not bringing air in or out of that makes sense lol

Air exchange can be accomplished with just the extraction fan on. Air will pull in from the vents, at the same time air is taken out. No worries.
 
If you are concerned about the air content add CO2. It is actually a very cheap input (after the initial set up that is) and there are many studies recently that say it can increase yield as much as 30% even when not pushing temps and light levels.

Either a controller and a regulator and a tank or a co2 generator powered by propane. Imo tank is easier because with the propane then you have to worry about more heat and if something goes wrong it's an explosive gas where as a co2 tank is a lot less risk in that area. Just search co2 meter and regulator on Amazon and you will find exactly what you need.then find a local gas place that caters to welders they will have a tank and re fills
