Over the past few days its been very damp and foggy and I walked into my greenhouse today were in growing tomatoes, lettuce etc and the humidity was 99% I opened the window and door to circulate the air and the humidity dropped to about 95% (I had to shut the window and door after 10 mins because the temperature was lowering) anyway I was wondering if there is any ways of reducing the humidity like I seen on the internet someone using a computer fan to circulate the air out the greenhouse.
thanks in advance
