Here's a copy and pasted of things you need to know about CO2 before splashing out!
For CO2 to work, you need....
- Bright Light - Your cannabis plants need a lot of light for CO2 to be effective at speeding up growth and increasing yields. As far as light intensity, we're talking about the kind of light produced by a 1000W HID grow light. CO2 only helps plants make more energy from bright light, so it won't help if you have low light levels.
- Enough CO2 - You must be able to maintain 1200-1500 PPM of CO2 in the grow area or it won't help your plants.
- Sealed Grow Space - You must be able to completely seal your grow space so CO2 can't get out.
- Temperature - You should maintain temperatures between 85°F (30°C) and 95°F (35°C) in your grow space for CO2 to be most effective.
- Humidity - You must keep humidity below 60-70% to prevent mold and other problems, but keeping humidity low can be difficult with a sealed room while running CO2. You may need to get a dehumidifier.
I know it may sound like a lot, but these factors are important! If you have the wrong setup, adding more CO2 isn't going to help you! Today I will share everything I wish I’d known about CO2 when I started growing, so you'll know exactly how you can use CO2 for faster growth and increased marijuana yields. Let's get started!
Beware! Some people (especially companies selling poor CO2 products) will try to trick you into thinking that CO2 is some magical supplement you add to your grow room to make plants grow better. Unfortunately this is not the case! There are good ways to add CO2... and there are ineffective ways.
