Active Air CO2 Replacement Regulator for Hydrofarm CO2 System

Description

This product is a replacement part for the old style HF COSYS, and is not a complete unit/system.

CO₂ is an odorless, invisible, and non-flammable gas. The average level of CO₂ in the atmosphere is about 300 ppmv (parts per million). If the level decreases down below 200 ppmv in an enclosed growing area, plant growth slows to a halt. Through the years of testing and research, the optimum enrichment level of CO₂ for plant growth has been established at 1500 ppmv. With CO₂ enrichment, under good conditions, plant growth rates and flowering will increase 20-100%. CO₂ can be used from seedling right through harvest.
