I am trying to figure out how to fog my 11' x 20' greenhouse. This will be a few times a year so i can control scale. If that proves too difficult I was thinking of making a fogging chamber and putting several orchids in at a time and fogging it with whatever I am using. Inside the greenhouse I can set up a 5gal bucket with a syphonex (for the insecticide mix) hooked up to the faucet and a short hose with a fogger nozzle on the end. Turn off all fans etc and let her rip!!!! Any thoughts? Most appreciated.
