Picture of Growing Square Watermelons for $8
This instructable explains my efforts to make cheap growing boxes for square watermelons. Learn from my mistakes, grow cuboid fruits, and save money at the same time! You can also read about it at my blog: GoodCleanCrazy

Supplies:
Plexiglass
Hacksaw
Drill with bits
Packing tape
Watermelon seeds
Cheap baling or fence wire.

Optional:
Holecutter bit

Step 1: Obtain Plexiglass

Commercial polycarbonate boxes for growing square watermelons run about $85 plus shipping. But you can make one for about $8 out of plexiglass. You'll need six rectangles of 1/4" or thicker plexiglass or other translucent plastic. Free and super cheap plastic pieces can be had from sign-making shops--ask for scraps! Or try to find a plastic supply warehouse that caters to farmers, these will usually be the cheapest source for plexiglass. If you buy plexiglass scraps, ask to have them cut into rectangles 8.5" x 8". If you are doing the cutting yourself, you can use a table saw, band saw, or a hand saw.

I'm not totally sure about everything you're asking, but as for the last one, the watermelon grows into the shape of the box, kinda like jello in a mold.
