funny

Told my guy i was thinking of putting my pet mouse, with a fan fitted to the mouse's wheel to help cool down my few pathetic plants - I thought Mickey could get exercise, cool down the plants and give them a bit of CO2 - my guy laughed so hard he nearly filled his pants.........
Anyhow have put some bicarb in a bottle in with the struggling babes (im such a novice) - should I take it out during 6 hr dark cycle?

If you want to cap it off, or take it out... either way works. You plants wont use the CO2 when light is not present, so if you can save CO2 by taking it out or closing the bottle then do it.
