How to make a co2 generator for plants

Extra bottle cap

1 tablespoon baker’s yeast
Feed enough tubing through the cap so to extend two inches into the bottle when the cap is on. Secure the tubing with a small amount of silicon sealant — allow the sealant to dry overnight.

Cover the bottle opening with an extra cap and shake the bottle to dissolve the sugar. Remove the cap and fill the bottle with more lukewarm water. The level should come to an inch below the tubing when you place the cap with the tubing on the bottle.
Aquarium line tubing
Carbon dioxide gas — CO2 — can be used for enriching the growing conditions for plants. Increasing the amount of CO2 in the growing environment produces larger plants. Plants can utilize about four times the amount of CO2 found in the atmosphere. You can make your own CO2 generator with yeast and a sugar solution. The yeast feed on the sugar and produce CO2 as a product of respiration. One bottle of yeast doesn’t produce much more CO2 than an animal does by exhaling, so if you want to fill your greenhouse, you’ll need many such generators.
Adding more sugar makes the generator produce CO2 for a longer length of time, but the process occurs more slowly. Adding more yeast, on the other hand, produces CO2 more quickly, but the generator will have a shorter life.
Add one tablespoon baker’s yeast and a pinch of baking soda to the bottle. Put on the cap and screw it on lightly. It shouldn’t be airtight, because excess gases in the bottle may need to escape.

Place the other end of the tubing near some plants in the greenhouse. It may take up to three days, but the yeast should start producing CO2 to feed the plants..

How to make a CO2 generator for your greenhouse/grow room plants

Step 3Using 1 cup measure fill about 1/3 full with lukewarm water. Add dry activated yeast and stir till dissolved. Using funnel add this to your water jug then fill to just over 1/2 way with more lukewarm but not hot water. Hot water will kill your yeast.
Step 6Cut enough airline tubing to go completely around your plants and attach both ends of the tubing to the “T”. Using plant tape or twist ties you will attach this tubing to the uprights you just made. Use the piece of airline attached to your water bottle lid to attach to the final end of your “T”

Step 4place lid onto container which is now your generator. Place generator in your greenhouse or grow room as close to your plants as possible.
Step 5take your coat hanger pieces or wooden stakes and stake 4 around the perimeter of your plants, you can put stakes in planters with the plants. These will be the uprights your airline tubing will attach to.
Things You’ll Need:
empty gallon water bottle or well washed milk jug.
1 Cup Sugar
1 heaping teaspoon of Activated Yeast.
craft iron
airline tubing or other such tubing to direct CO2 to your plants
twist ties to attach tubing to uprights
coat hanger, garden stakes or some other thing to act as a holder for your CO2 curtain
pocket knife or punch to make holes into tubing.
1 “T” connector for your tubing.

Step 1plug in craft iron, when it is hot enough you will use it to burn a hole into the lid of your gallon water bottle. The hole must be just large enough to force the tubing into it. Force end of tubing into the lid from the outside to the inside entering the jug about 1/4 inch.
If you have a greenhouse or grow room and have wanted to put in a CO2 system but couldn’t afford the expense or had difficulty with how technical one can be to set up and run, have I got the solution for you! Well it is easy for anyone to set up and use this simple CO2 generator for healthy and vibrant plants. As you know plants take in CO2 during the day and expel Oxygen, at night they do the reverse but to a lesser degree. In order for your plants to thrive they need CO2. You could leave the door open for fresh air, but in the winter your plants could freeze and opening the doors invites all sorts of plant eating pests. Making a simple generator to use solves those problems.

Step 2Fill water jug 1/3 with lukewarm water then using a funnel add 1 cup of sugar. Shake well to dissolve as much sugar as possible.
