Grow Box

Question

Does Grow Box have to be brought indoors when it rains in summer?

Answer 1

Only if the plants are already pretty well soaked and the risk of root-rot would be introduced by the rain. If you only expect a light shower or a very short period of light to medium rain, it should be fine and you won't have to water for a little while.
