How to water grow bags:
Lightly.

Be careful that your soil mix has a LOT of drainage and the bags aren't sitting in trays- putting them up on a grate to ensure that runoff flows out freely is a good idea.
foxysox Reviewed by foxysox on . What's the best way to water when using grow bags? I picked up some Dirty Harry from Rushman. They are about a month old now and I did not realize how big these would get. They are getting so big. I don't have the room for a bunch of 5 gal buckets or pots so I ordered 5 gal grow bags. Buckets and pots have a lip on the bottom so the drain holes are not sitting directly on the floor which helps the water drain easier. I know grow bags have drain holes on the bottom but if they are sitting directly on the floor can they still drain properly? Is Rating: 5
