Johnson Gas Carbon Dioxide Generator

IMPROVE PLANT QUALITY 
INCREASE PRODUCTION
 CO₂ ENRICHMENT –THE PLANT NUTRIENT FOR THE 22nd CENTURY.

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 Gas CO₂ Generator automatically provides the carbon dioxide to meet maximum growing potentials, and operates for only pennies a day

The Johnson Gas 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 every­ where ‑ use Johnson Gas CO₂ Generators‑ the low cost way to produce C0² the nutrient of the 90's.

Johnson CO₂ Generator fertilizes greenhouse air and is easy and inexpensive to install

Why you get more rapid and efficient growth and better plant quality with the Johnson Gas 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 (PPM) of CO₂ in the atmosphere; when this level is increased to over 1,000 ppm, results are higher production and better plant quality. the AEON International Corporation vides 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 around100 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 Gas 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 C0²Generator

When there is sunlight and the vents are closed, CO₂ should be added continuously to your greenhouse. If the vents am 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 CO₂ level 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 AEON International Corporation Generator daily in winter from approximately 7:30 a.m. to 4:30 p.m.

Easy and inexpensive to install

You can install the Johnson Gas CO₂ Generator easily in any greenhouse. In fact, most growers do it themselves. No expensive duct work necessary. The CO₂ is diffused evenly throughout the greenhouse without supplemental fans.

 Automatic… fully adjustable

Completely automatic, the Johnson Gas unit comes complete with a gas pressure gauge. Simply set the gauge to the pressure desired for your greenhouse area and the Johnson Gas Generator will automatically provide the correct amount of CO₂. Just as you adjust the amount of water and fertilizer to meet the changing needs of your plants, you also set the AEON International Corporation Generator to produce the desired amount Of CO₂ for your greenhouse. The Johnson Gas unit includes a 24V. gas valve. A timer or a combination timer thermostat, which automatically turns the units on in the morning and off in the evening as desired, can activate this valve.

Safe…. requires no floor space….rugged construction

In case of flame failure, gas supply shuts off automatically and the Johnson Gas unit saves you valuable floor space. It hangs from the rafters… completely out of the way.  It's only 18" in diameter and 20" high, it weighs 21 lbs. and is easy to move.

The Johnson Gas generator is constructed of special heavy  gauge aluminized steel for maximum corrosion resist­ and long life.
