Fog is an excellent alternative to mist for germination and propagation in greenhouses for many reasons. It provides a more uniform wetting across the plants in your greenhouse. It achieves deeper penetration into the foliage, it is more efficient and has lower maintenance costs. It doesn’t take much management to keep the humidity high and not saturate your growing medium. It is also excellent for cooling.
As air temperatures build in greenhouses water loss from the plants can exceed the amount of water the plants can take up. Using fog in this situation lowers air temperature, increases the humidity of the air, and does not saturate the growing mediums exposing them to fungi, moss, and gnats.
The Jain Turbo Fogger can also be used outdoors in orchards. Growers have success outdoors with foliar fertigation, pesticide and fungicide applications. There is a huge time saving because it only takes 10 -15 seconds for an application. Nozzles are flushed after every spray. Unused chemicals are captured, and there is a much lower operating cost than traditional orchard applications.

Design A Turbo Fog System
Turbo Fog systems are relatively easy to design for growers familiar with irrigation. You first need to select a nozzle size based on your droplet size requirement. Jain has excellent diagrams (Download 1) (Download 2) to help you with the process. Next, you need to determine the number of nozzles required. Calculate the air flow and water flow requirements and select a compressor that will provide the desired pressure.
Requirements For A 40’ x 30’ Greenhouse
Using a reference chart, we determine we need 30 nozzles to maintain 85% humidity. Also we need 35 psi of water pressure and 30 psi of air pressure. By also consulting our chart we see we need a compressor producing 14.42 cubic feet per minute. We built a 15% safety factor into this calculation.
