I am trying create a very humid environment to help start softwood cuttings in s small greenhouse. Anyone know of a small (around 1 gal.) humidifer that does not have an automatic shutoff control on it? I have tried three different units and they will not allow the environment to get humid enough (dripping wet). Thanks.
I would check greenhouse suppliers.
You also can use plastic to tent the plants.
You also need to provide air circulation as to not cause mold and fungus growth.
