I have a baby tree that requires 70%+ humidity in order to thrive. Since I can't really replicate that inside the house easily, I bought a 4x6 ft greenhouse from Amazon and set it up in partial shade under a giant oak tree. I basically use the hose to spray the ceiling of the greenhouse so the water comes down like rain rather than spraying the plant directly... Then I filled up a 5 gallon bucket full of water to help provide a source to elevate the humidity.
Well, yesterday it rained all day so I never went out to check it. This morning I took a peek inside the greenhouse and was shocked to find the 5 gallon bucket completely empty! I am so surprised that entire bucket evaporated in a single rainy day!
