Do It Yourself CO2 Enhancer

What was that DIY CO2 recipe you did on your livestream? Hands down, this is the number one question I get asked. I got this on Instagram from @masteryoda306 and saw @namelesscults_ post this recipe on Instagram, then tried it out for myself on my Instagram livestream show. Obligatory plug: come watch me live every Saturday at 6:30pm EST. I do a lot of DIY recipes and tent maintenance.

Why do you even need a CO2 enhancer? All plants feed themselves through photosynthesis. The basic equation for photosynthesis is:

6CO2 + 6H2O + sunlight = C6H12O6 + 6O2

More simply, your plant takes in carbon dioxide and water, then uses energy from the sun to convert it into sugar and oxygen. In a tent environment, if you can increase the amount of available CO2 then your plant can take more in and create more sugar to feed itself, making bigger and better bud sites.

There are products out there available to purchase, like TNB Naturals. It’s a great solution, and we have them in some of our tents. But if you want a cheap do-it-yourself recipe, look no further.

First, you’ll need a 2 liter bottle, and you need to black it out all over. Whether you want to spray paint it, duct tape it, whatever. Just make sure there is no light penetrating the bottle. This recipe fits a 2L bottle, but you know that I value a nice aesthetic so I used a Simply Lemonade bottle instead. The shape is just chic. Plus, the cap is Chef Anna Green so I had to. I painted the lemonade bottle with white spray paint then followed up with an acrylic sealer. Then puncture the cap of your bottle cap to give the CO2 an avenue to escape.

Once your bottle is dry, you’re ready to mix up your CO2 recipe. Here’s everything you’ll be using:


2 cups sugar

1 tablespoon active dry yeast

1 tablespoon baking soda

1 Liter warm water

First mix all your dry ingredients: 2 cups of sugar, 1 tbsp active dry yeast and 1 tbsp baking soda. Stir this all together so it’s equally distributed.

Pour your dry mixture into your blacked out bottle, then add 1 Liter of warm water. If you used a container smaller that 2 Liters, like a Simply Lemonade bottle, then cut down on the sugar and water equally so that your bottle is no more than 2/3 filled. Otherwise you risk your mixture overflowing.

Put the cap of the bottle back on, and shake up your new DIY CO2 enhancer, making sure to cover your puncture hole so you don’t spray everywhere. It’ll take a few days for this mixture to start making CO2, so don’t worry if you don’t see immediate results. Hang it up in your tent and shake it up every day. After a few days you’ll notice it making the Ssssss noise that a pop bottle makes, so you’ll know it’s working.
