I have a plastic walk in greenhouse in which I am attempting to grow melons, peppers and aubergines in this year. I try and leave the door open as much as possible so as to encourage some air flow, but it still get's pretty warm in there!
My problem is that over the weekend I noticed that there was some brown mould starting to grow on the surface of the compost. I assume this is due to me possibly having overwatered (although the plants themselves are thriving) and maybe not sufficient ventilation. Can anyone tell me if I'm right, and is there anything I should be doing to prevent it, can I get rid of it?
Many thanks
