Monitor, Control and Supplement your CO2 Supply with the EcoTechnics Evolution PPM Controller

Once you've mastered the art of indoor gardening, take the plunge into growing with supplemental CO2, using the simple yet effective EcoTechnics Evolution PPM Controller. Both smart and stylish, the EcoTechnics Evolution PPM controller can be attached to either a CO2 regulator and solenoid valve or a propane gas burner to increase the CO2 levels in your growing area. Once your growing room is totally dialled in, CO2 becomes the limiting factor, so the next logical step is to increase CO2 levels, boosting your plants' growth rates and maximizing yields beyond anything you've experienced before!

How the EcoTechnics Evolution PPM Controller Works

CO2 is a naturally occurring gas that plays an essential role in the process of photosynthesis. Typically, the atmosphere around us has CO2 present in concentrations of around 360 parts per million (ppm). Plants can use up this ambient level of CO2 within an hour, and when levels drop below 200ppm, growth will quickly start to stall. This issue can be addressed by equipping your grow room with an adequate extraction system; however, plants can use more CO2 than is generally present in the atmosphere. When used correctly, supplementary CO2 has numerous benefits, it makes plants more tolerant to higher temperatures, triggers amplified growth rates, leading to improved harvests, in terms of quality and quantity. Optimal levels of CO2 are between 1000ppm and 1200ppm; levels higher than this can be detrimental, while levels above 2000ppm actually become toxic to your plants. At 4000ppm to 5000ppm levels become toxic to humans!

The EcoTechnics Evolution PPM Controller is the perfect way to monitor, regulate and supplement CO2 in your grow area. When used in conjunction with either a CO2 tank (via a regulator) or a propane gas burner it will maintain a consistent level of CO2 in the grow area at any given time. The EcoTechnics Evolution PPM Controller initiates either the CO2 regulator or the propane burner when CO2 levels start to fall, correcting the ppm (parts per million) levels, for explosive growth and heavier blooms.

The EcoTechnics Evolution PPM Controller has built-in memory that allows it to be switched off without losing its settings. This means that you can put it on a timer and stop dosing during dark periods. When plants aren't photosynthesising they don't need a supply of CO2 - any supplementation performed at such times would only be wasteful. Ecotechnics designed the PPM in such a way that you can dose only when it's needed.

The EcoTechnics Evolution PPM Controller has 'intelligent dose' and 'learn' functions, adding extra CO2 when needed and storing that information for future use. The dose function can sense when CO2 levels are too high as well as too low. This function slows the flow of CO2, allowing your extraction system to take over and purge the excess levels from the area. This keeps your plants happy and healthy, avoiding any chance of toxic CO2 levels becoming an issue.

The automated learn function keeps information about your growing environment for future use, anticipating potential CO2 issues before they arise. Simply put, the EcoTechnics Evolution PPM Controller can monitor and regulate CO2 levels, leaving you extra time to enjoy your indoor garden and boosting your growth rate and yields beyond belief.
