Boost CO2......the cheap and easy way?

Idea.

Place a beaker/recepticle in the center of your grow room under the plants. Fill with 20% vinegar water solution and add in 2 teaspoons of baking powder. Repeat once a week.

Vinegar and baking powder react and the bubbles are CO2.

Opinions please.

You mean vinegar and baking soda.

And you'd wanna change it every hour.

Sodium Bicarbonate.......Baking powder in the UK sometimes.

How come every hour? Theres quite a lot of gaseous CO2 locked in that solid powder.

I havnt tried it, but CO2 would get trapped under the canopy for a least a day surely.

Maybe. Baking powder in the us has some sodium bicarbonate, but much less than baking soda which is straight.

Generally, co2 is added to a sealed room, so a lot would get sucked out through the exhaust. Worth a test though.

cheers, yup 100% sodium bicarb in the cupboard.

Cant hurt, suppose it depends how long long it bubbles for and how much you use.

If the reaction yields enough to help the planties, maybe just turning of the fans for half a day when you add it.

how big is your grow room ,you might not even need it if you have fresh air coming in ,i tried those diy co2 sugar and yeast and all i did was make some stinky ass alcohol ,and didnt see any improvement ,ran fresh air intake to room from eave of house and them things took off ,matter of fact i had to supercrop the things today ,they are 2 ft tall which is what i wanted ,once in flower probally twice that.dont waste your money if you dont have to
