Hello everyone, I just had a greenhouse built and am having trouble keeping the humidity up in it. The floor is just weedblock with pavers in the pathways. My husband wants to put pea gravel under the benches and I want to put cyprus mulch but am afraid that it will breakdown and turn to dirt. Every morning the humidity is about 25% and I wet down the floor and it may increase it to about 35%. The heater is probably responsible for this low humidity in the mornings. Misters are not an option at the moment because I don't have water in the greenhouse, except for the garden hose when its warm enough. I am sorry if this has been discussed before, but I kept getting the "whoops" message when I clicked on anything pertaining to this issue. Thanks for any opinions and suggestions.
