Yes, if we like plants, trees and forests we need to produce more CO2. That machine is sold to greenhouse owners so the plants grow faster…
Carbon dioxide is one of the essential ingredients in green plant growth, and is a primary environmental factor in greenhouses. CO2 enrichment at 2, 3 or 4 times natural concentration will cause plants to grow faster and improve plant quality.
Modern growers are becoming increasingly aware of the value of CO2. Particularly now that most greenhouses are purposely shutting out CO2 to conserve energy.
The Johnson CO2 Generator automatically provides the carbon dioxide to meet maximum growing potentials – and operates for only pennies a day. The Johnson Generator can easily be installed in any greenhouse. No expensive ductwork is necessary and CO2 is diffused evenly without supplemental fans.
Join with modern growers everywhere – use Johnson CO2 Generators – the low cost way to produce CO2 – the nutrient of the new millennium.
