i guess i should have been more specific. the room is not vented at all..its just not 100% sealed like there is no vacuum when you open the door.
but what i mean was..my controller that reads the ppm levels..where is the best location for it in my room
just a couple questions. im adding co2 to my room and i will be using a controller
1. does my room have to be completely sealed to get the benefits of co2? or will i just be using bottles faster?
2. where is the best location for my co2 controller to get good readings?
i just flushed a few weeks ago. i was thinking maybe also salt build up,from the FF products. maybe flush with my clearex this time and start with a new line of products. or am i wrong
