Ecotechnics CO2 Regulator Solenoid Valve Manometer

This manometer measures and controls the gas pressure of your CO2 cylinder.

Works perfectly with the Ecotechnics Evolution CO2 Controller

It has a fixed flow rate of 17 liters per minute
It is very reliable and very simple to set up and use.
It connects to your CO2 cylinder and is wired to your CO2 controller
The ambient level of CO2 in the air is 300 to 400 ppm.

Plants growing in your grow room or greenhouse can use up all the available CO2 in less than an hour and cause a slowdown in photosynthesis. Therefore carbon dioxide (CO2) is one of the most important factors.
Photosynthesis is a biochemical process that allows plants, algae and some microorganisms, thanks to the energy provided by the sun's rays, to transform water and CO2 into organic matter (carbohydrates). The reaction is an oxidation of CO2 by water. The plant through photosynthesis rejects oxygen into the atmosphere. However, the plant breathes and the reverse process occurs with a release of CO2 and unlike photosynthesis which is carried out only during the day, the plant breathes day and night.

The balance in terms of capturing CO2 in the atmosphere (photosynthesis minus respiration) varies according to the plant. However, the balance is very positive since it is estimated at 50% (i.e. half of the CO2 captured is not rejected and is used for the growth of the plant).
