My office mate Chris G. and I wanted some hanging planters, but we wanted to be able to hang them higher than we could easily water them. So we made these counterweight balanced vertically adjustable hanging planters. Now we can easily reposition them based on our every whim!
Here is a vine of it: https://vine.co/v/hWDhp0tgw7Z
Step 1: Mounting Hardware
This is where the generous kind and all around cool facilities folks - the ones you have to ask if you want to, say, drill holes in your nice fancy new building, come in. Not only was Kevin cool with it, but Ryan and Cornelle actually mounted the 80/20 for us.
So: mount a rail of 80/20, or anything sufficient to carry the load, above where you want your planters. This is where you'll mount your pulleys. Set them up so each horizontal planter has:
1 pulley for each side
1 extra pulley on the side on which you plan to place your counterweight. This will become clearer in the next step....
You can use any pulley that will carry the load - but probably cheap pulleys, that add some friction, will work best. You want the planter to be able to move up and down, but not without friction. A nearly friction-free pulley would force you to adjust the counterweight whenever you changed the weight of the planter (i.e. after watering the plants). Some friction makes thing moveable, but not too easily, so they won't move on their own.
