What is the best way to remove mold in the greenhouse?
Re:In a greenhouse/to get rid of mold/Sand rooting bench-Is it safe (for plants) to flush a sand rooting bench with a 50% solution of bleach followed by a flush with water?
Answer
I think you would probably be sorry that you used bleach for ridding the sand of the mold. Have you tried some of the products that are in the garden centers for getting rid of mold that are safe for plants? We do know that heavily chlorinated water is harmful to plants, thus a 50% solution would definitely be trouble!
