With summer coming to an end, I decided to start working on some indoor planters. After checking out the selection of various pots and window boxes at the home improvement store, I wound up with nothing that would work for my tiny windowsills. After wandering past some rain gutters, a plan sprang to mind. I purchased a 10′ plastic rain gutter ($6), four end caps ($4 ea) and a tube of adhesive caulk($5).
I cut the gutters down to the width of the window I wanted to use, attached the end caps with the adhesive caulk and attached them. Next, take a length of nylon webbing long enough to go from half way along the bottom of your gutter and into the window. This will serve as a stabilizer for the planter when the window is closed. For us, it also serves as a way to prevent the cats from accidentally knocking it off. Allow the caulk/glue to cure for 24 hours.
Add some gravel for drainage, I used about an inch in the bottom of the container. Add your potting soil and plants and you have a nice looking indoor planter. I used this one to transfer lettuce seedlings, hopefully we’ll have a great indoor crop.
Update: If you have a child or pet who is likely to yank this or climb on it, use screws and washers to screw down the nylon webbing for added security. I discovered this the hard way when a cat decided to pull my planter down causing dirt, gravel and seedlings to go 10′ in all directions.
