I am putting together a new 450 sqft GH in Santa Barbara CA, for intermediate botanical mounted species. I am thinking about maintaining rather high humidity in the GH. I see three options and wonder about pros/cons. - Ultrasonic foggers. Most likely not producing enough mist/fog even with say 4 units of 5-head foggers. - Mistking 160 PSI system. Could work, as under bench misters, but if I try place do some also under the ridge line, I am concerned about water droplets on plants and rot. - 1000 PSI system. I think this is what institutional greenhouses use. I am looking at High Pressure Misting Kit 1000 PSI - Flexible and that may work on a smaller home GH. Or is this complete overkill? Any experiences with any of those systems? Alternatives? Recommendations?
