The boxes come with lids, so from each box you get one deep tray and one shallow tray. I prefer the shallow lids for raising sprouts, such as sunflower seed sprouts and wheat grass. The deeper bottoms can be used for sprouting also, but I use them mostly for holding seedlings in cups of soil.
By hanging things up in the air, you avoid problems from rats, snails, slugs, and ground-crawling insects.
To hang the boxes I use galvanized iron wire and "S" hooks bent out of 1/4 inch rebar.
CPVC pipe goes through some of the vent holes, providing attachment points for the ends of the four wires that hold the planter.
Step 1: TOOLS AND MATERIALS
MATERIALS: Styrofoam grape box, 1/2 inch CPVC pipe, 1/2 inch PVC pipe, wire.
Step 2: CUT THE PIPE
There are some variations in the wall thickness of the PVC pipe. I use the thicker-walled pipe to make the end rings. They make a tight pressure fit over the CPVC pipe. Thin-walled PVC pipe fits too loosely for the purpose it serves in this project.
The grape boxes come in different widths sometimes. Measure and cut two pieces of the smaller diameter CPVC pipe. They should be long enough to stick out about 1 1/2 inches, or 2 inches on either side of the box.
Cut four sections of the 1/2 inch PVC that are about 3/4 inch long. These are the end rings that increase the outside diameter of the CPVC sections, thus preventing the wire used for hanging the planter from sliding off the end of the pipe.
Since you have to trim the inside of one end of the rings, and holding small objects can be dangerous while trimming them with a knife, I do the trimming of each ring before cutting it off the end of the pipe with the saw. Trim-cut, trim-cut, trim-cut, trim-cut. (See the diagram in Step 4.)
Step 3: PUSH THE CPVC PIPE THROUGH THE HOLES
Step 4: TAP THE END RINGS ON
I like the system I am demonstrating because the wires can be easily removed from the pipe ends if for some reason I want to have the box without the wires. The loops at the ends of the wire just slide over the end rings when the tension on the wires is relaxed.
Step 5: BEND THE WIRES TO MAKE a HANGING LOOP
Cut two sections of wire about 6 ft. long. Bend them both in half, run a piece of pipe through them temporarily and start twisting. Each of the wires will be about 3 ft. long. Bending the wires can be done by hand, but a pair of pliers may come in handy for getting tight bends and for cutting the excess wire off when you are done.
Step 6: BEND THE END LOOPS
After getting all four wires started together, I finish them individually, twisting the wires tightly.
After slipping the wire loops over the end rings of the pipes, I pinch them closed a little bit so that they don't come off accidentally.
Step 7: HANG IT UP
Step 8: FILL IT UP
Bring on the seeds!
