Johnson CO2 Generator
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 and help save the planet.
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.
Why you get more rapid and efficient growth and better plant quality with Johnson CO2.
Plants must absorb carbon dioxide (CO2) in combination with water, soil nutrients and sunlight to produce the sugars vital for growth. A shortage of any of these requirements will retard the growing process. Normally there are approximately 300 parts per million of CO2 in the atmosphere; when this level is increased to over 1 ,000 ppm, results are higher production and better plant quality. The Johnson Generator provides up to 1,500 ppm per unit in an average 24′ x 200′ greenhouse or an equivalent 50,000 cu. ft. volume based on one air change per hour.
Nighttime levels in a greenhouse range from 400 to 500 ppm due to plant respiration. Shortly after sunrise this level will drop to normal atmosphere (300 ppm) due to the plant using the early light to start photosynthesis. After 3 to 4 hours of early morning sunlight the CO2 level can drop to around l00 to 150 ppm, then growth is practically stopped. Supplemental CO2 added during this period can substantially increase your plant and flower production. By adding CO2, during winter months when greenhouse ventilators are closed and when low CO2 concentration becomes a limiting factor in growth, users are obtaining yield and bloom quality which is normally associated with spring and summer.
CO2 More Important Than Ever
The Johnson CO2 Generator is more important than ever because greenhouse growers, trying to conserve energy, are shutting out CO2. Rising fuel costs have forced many growers to use doubled-layered glass, etc., to conserve energy – as a result much less CO2 is entering the greenhouse.
How to use the Johnson CO2 Generator
When there is sunlight and the vents are closed, CO2 should be added continuously to your greenhouse. If the vents are opened because of heat build up the generator should continue to operate for about 2 hours and then be shut off. Approximately 1 Lb. of CO2 per hour per 1,000 sq. ft. yields 1,000 ppm’s of CO2. A 4,000 sq. ft. house requires at least 4 Lbs. of CO2 per hour. If CO21evel drops off from 1,000 ppm’s to 500 ppm’s on a clear sunny day, you can easily adjust to a higher burning rate to make up for the more rapid absorption of CO2 by plants. Most growers use their Johnson Generator daily in winter from approximately 7:30 a.m. to 4:30 p.m.

Would it be cheaper option lto get all tge the LIB/LAB/DEM/GREEN politicians we have in Canberra in a greenhouse and make them fatf lfor a living?
And pigs will fly, that is those without swine fever.Editor
We should run this story on the ABC – really, with their mandate ( legislated I believe ) for unbiased, even handed reporting and our 1.1Billion dollars a year they could make a feauture of it!
Our veggies are growing very poorly this year, despite water, fertiliser and loving care.Dare I say it’s because the Co2 is being depleted from the air by all that money being thrown at decreasing it?(am being very facetious here!)
