Johnson CO2 Enrichment

JOHNSON CO2 GENERATOR

Johnson CO2 Enrichment - the Nutrient of the 90's Improve plant quality - Increase Production

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 duct work is necessary and the CO2 production is diffused evenly without supplemental fans.

Join with modern growers every where use Johnson CO2 Generators the low cost way to produce CO2the nutrient of the 90's.

Why you get more rapid and efficient growth and better plant quality with a Johnson CO2 generator. 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 100 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 limiting factor in growth, users are obtaining yield and bloom quality which is normally associated with spring and summer.

The Johnson CO2 generator is perfect for greenhouse CO2 production, flower CO2 producers, agriculture CO2 enrichment, warehouse CO2 units, and vegetable CO2 units

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 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 Johnson 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 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 unit comes complete with a gas pressure gauge. Simply set the gauge to the gas pressure desired for your greenhouse area and the Johnson 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 Johnson Generator to produce the desired amount of CO2 for your greenhouse. The Johnson unit includes a 24V. gas valve. This can be activated by a timer or a combination timer thermostat, which automatically turns the units on in the morning and off in the evening as desired. (Optional).

Safe... requires no floor space... rugged construction

In case of flame failure, gas supply shuts off automatically and the Johnson 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 generator is constructed of special heavy gauge aluminized steel for maximum corrosion resistance and long life.
