What is BiO2?

BiO2 is an all natural CO2 enrichment program that has been proportioned for use within small environment grow rooms. By small we mean 10 x 5 or less. It is the perfect solution for use with all tents and grow boxes to avoid the high cost associated with bottles and meters. The deployment method works well within the grow room environments and provides many benefits. When the light(s) come on and raise the room temperatures the BiO2 reaction happens in earnest which results in optimum production levels during the day which is when the CO2 is beneficial. Then, once the light(s) go out, the reaction begins to slow which is when you do not require CO2 enhancement, thus resulting in optimum CO2 conditions. All this occurs naturally via the BiO2 System and the standard temperatures maintained in indoor garden environments.

Another benefit of the BiO2 System is the low cost and low maintenance required for installation and use. On average, one packet of BiO2 Biological CO2 Enhancement is used per week to maintain optimum levels within your 175ft3 grow room. If you purchase a BiO2 Bucket Kit everything you need, except sugar, is included and you may begin to garden with CO2 as soon as you get home. If you purchase a BiO2 Starter Kit all you will need is a sealable 20L container and sugar to begin CO2 production in your garden as soon as you get home. The ease with which you install the system makes gardening with BiO2 a breeze. Anyone can use the system following the simple instructions provided in each Kit or available online at

An optional BiO2 Accessory Kit fills out the line for the BiO2 Biological CO2 Enhancement System. This kit provides the essentials for maximizing the ease with which you may utilize the BiO2 system. The kit includes a bucket opener and a light weight rubber mallet, to minimize damage caused from weekly replacement of the BiO2 packets, a stir stick, a pre-cut PVC tape strip to make a full seal on the bucket, and a stick-on liquid crystal temperature gauge to ensure proper start up conditions. 

The greatest advantage of the BiO2 Biological CO2 Enhancement system is the harvest increases and overall health benefits to your favorite plants!
