CO2Boost works from a combination of all-natural ingredients from the composting arena. Those ingredients are mixed and placed in the bucket where the CO2 is then naturally created. The pump is inserted into the bucket and our all-natural CO2 is released to your plants. Use our lay flat tubing to distribute the heavy gas above your plants. This product is unique in the fact that it doesn't work by raising ppm levels, it works by distributing CO2directly to your plants.
