Convert vegetable scraps to wonderous worm castings
[Design by VermiTech specialist Todd Spratt of Blue Belly Farm]
Make your own VermiComposting Worm Bin
Begin with 1 pound of red worms. Allow one square foot of surface area for each pound
of worms. Red worms will consume 1/2 pound of vegetable scraps per day. Feed every 24 hours,
increasing as necessary as worms multiply. (If worms don't consume all of the scraps,
decrease the amount of food.)
The basic idea of this design is to create a raised interior floor,
thus allowing moisture to drain away from the bedding, and allow air to
circulte beneath the bedding. The nutrient rich moisture which is collected can
then be used for watering plants.

INSTRUCTIONS
1
. Drill a one inch hole in the side at one end of your storage container at the center
and as near the bottom as possible.
2
. Using a saw or knife cut the top off the water bottle just below the rim.
3
. Unscrew the cap and apply a bead of adhesive or caulk around the hole on the inside of the bin.
4
. Slip the bottle top through the hole from the inside and screw the cap back on.
This will act as your drain (body of bottle is inside the box). Note: you may have to enlarge
the hole slightly with a knife or file, so make sure the bottle top fits through the hole before
applying the adhesive.
5
. Now drill four 1 inch vent holes in the side at each end of the bin, 2 at the top and 2 at the bottom.
Note: make sure the bottom vent holes are above the drain, but below the raised floor.
6
. Apply adhesive around the vent holes on the inside of the bin and attach a 2 inch square piece of
sturdy window screen over the holes.
7
. Cut the 1x3 raised floor supports to the length of the inside of the bottom of the bin.
8
. Place the 1x3's on the edge: one on each side and one down the middle. You may want four,
depending on the strength of your flats.
9
. Cut the nursery flats with scissors or snips to fit on top of the 1x3's inside the bottom of the bin.
The flats will overlap where they meet, then screw or staple the flats to the 1x3 wood supports.
You may also replace the flats with wire mesh or plywood with holes drilled in it.
10
. Add a layer of cardboard or paper over raised floor before adding bedding.
