All you need to do is take an empty Gallon jug and add hot water half full, then add all the sugar that will dissolve and let it cool to room temp. Add a packet of bread yeast and shake it up.
Put the jug on a shelf higher than the plants, and pour off some once a week, then add more sugar and warm water.
PamStoner Reviewed by PamStoner on . Co2 Would this work? My room isn't quite sealed so I was thinking of a new way to use co2. I was finding different ways to use co2 in a room and I came across excellofizz (see photo). I'm not sure but I heard that you only have to add co2 for about 15 minutes every 3 days or so. Anyway would it be possible to put a large bin on top of the plants and use one of these excellofizz tablets. If you think this would work please tell me. Also if my time is off could you please tell me what you think would work. Thanks for Rating: 5
