Test for your CO2 levels with this easy to use kit. The kit comes with 100cc syringe, 2 test tubes and instructions. Each test tube is good for 1 test. Just fill the syringe with 100cc of your grow area air, preferably taken at plant level, break off the ends of a test tube, insert test tube into the syringe and slowly force the air sample from the syringe through the test tube. This should take about 1 minute. Take your estimated ppm CO2 reading from where the tube turns from purple back to white. Optimum CO2 levels are 1200-1500ppm.
