The CO2 Tester Refill Tube is an essential piece for growers to have on hand to measure the CO2 in a grow room’s air to ensure optimal CO2 levels for plant growth. The CO2 Tester Refill is a replacement detection tube. These are to be used in combination with the syringe provided in the CO2 Tester kit.
We recommend measuring CO2 periodically to ensure optimum levels for growth. The CO2 Tester Kit is an inexpensive alternative to costly electronic monitors. Use the tester kit to gauge proper CO2 level, as well as eliminate waste and optimize growth. The kit is inexpensive and easy to use, and includes instructions.
