Greenhouse Growers Tell Climate Crazies More – not less – Carbon is Needed
Is more carbon dioxide in the atmosphere a bad thing? Not according to horticulturalists. They are the experts when it comes to getting the best yield on greenhouse-grown plants. For generations cultivators have filled their greenhouses with carbon dioxide (CO2), specifically to boost plant growth.
Likewise, more CO2 in the atmosphere means a greener, cleaner, healthier planet. As an example, below is an extract about the Johnson CO2 Generator, successfully used by greenhouse growers since 1901. Plant growers understand how crucial more (not less!) CO2 in our carbon-starved atmosphere is good for us all.
Are politicians willing to learn from greenhouse operators? Such knowledge will enable them to challenge the climate-change alarmist propaganda, which wrongly classifies carbon dioxide as a pollutant.
The advertisement (link here : http://www.johnsongas.com/industrial/CO2Gen.asp) for the Johnson CO2 generator reveals that:
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.
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.
Night time 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.
