New to forum and my first post.
I am a full time market farmer and will be starting a hydroponic lettuce operation soon. I am looking for advise, comments or suggestions on how to cool my 750 sq ft greehouse.
I am located in south central Kentucky where just yesterday we had outside temperature of 93 degrees. With 50% shade cloth and exhaust fan running the house was 99 degrees inside.
I am considering, misters, wet wall evaporative cooling or a chiller on the nutrient reservoir. Maybe a combination of some of these techniques.
I will be doing NFT gutters.
Any advise would be greatly appreciated!
