DIY - Homemade CO2 System for Indoor Marijuana Plants - EASY

Hey guys! This is my tutorial on how to make your own homemade CO2 Redneck system. All I used was sugar and dry yiest, then I just add my water and shake it up. I use aquarium tubing and fittings to connect everything, and feed it to the fan. A good tip if your tubing is rolled up, to straighten it out put it in a pot of hot water, then remove it after a minute and stretch it out. Let me know if you have any questions! It works really great, your plants will benefit from having co2. This is what I use for my medical marijuana / cannabis closet grow.
