more efficient for u should be keeping the temps about 28C constantly to have your co2 work perfectly.
and i would also recommend u to change the soil to hydro if u want to see your co2 at real work thats the only way.
key to using co2 is right temp and right humidity. and air tight sealed room might need aiir cooled reflectors.
u can cheack out daltron's bio bucket thats a great way to start |
