Johnson CO2 Generator
$1,219.00
Normally there are approximately 300 parts per million (PPM) of CO2 in the atmosphere; when this level is increased to over 1000 PPM, it results in higher production and better plant quality. The Johnson Generator provides up to 1500 PPM per unit in a 4800 square foot (446 square meter) greenhouse. By adding CO2, especially during the winter months when greenhouse ventilators are closed and when low CO2 concentration becomes a limiting factor in growth, growers are obtaining yield and bloom quality similar to that which is normally associated with spring and summer conditions.

How To Use It
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 10,000 sq. ft. yields 1,000 ppm’s of CO2. 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 am to 4:30 pm.
