Monitoring Carbon Dioxide CO2 Levels in Your Grow Room

If you're using CO2 enrichment in your grow room then you're going to want to make sure you've got an accurate measurements of your CO2 levels.

Typical ambient carbon dioxide levels are around 400 PPMs, but if you really want to supercharge your plant growth and increase your yields by up to 20-40% then you're going to want to target around 1500 PPMs. 

We can talk more about CO2 enrichment techniques for your indoor garden in another post, but for now I just wanted to share some good CO2 monitoring tools that I've found. These will give you accurate readings of your carbon dioxide levels so you can tell if your enrichment technique is working properly.
