Hi Adam

I can help but the size i give will be in metric!!

My grow boxes are 390mm x 400mm by 140mm height.

All following sizes are in millimeters
1 piece of timber 70 x 20 at 2000 (2 meters)
1 piece of timber 120 x 20 at 1500
2 bits of whatever timber you have laying around (optional - for the feet) at 350mm each
4 of 90 degree corner brackets.
1 piece of plastic netting (or flywire mesh) for the bottom

Cut the 70 x 20 timber into 5 equal 400mm lengths - this is for the bottom of the box.
Cut the 120 x 20 timber into 2 sides at 400 and two sides at 350.

Nail or screw the 120 x 20 timber sides together to form a square shape thats outter measurements are 400 x 390 (the 350mm side plus the 20mm width of the front and back pieces = 390). These are the sides of the box.

Nail the 5 pieces of 70 x 20 timber onto the bottom leaving even spaces between the slats for drainage. Then at 90 degrees from these slats, nail on the feet timber (if you are going to have feet).

Nail or screw the corner brackets onto the four corners of the sides of the box. This will help stop the timber swelling and falling apart with time as the box gets wet....

Lastly put the mesh into the bottom of the box to stop the soil falling through.

For bigger or smaller or taller boxes, or if you want to use thiner timber, just ajust the sizes of the timber that you use. But remember you will be watering these boxes alot! i made some once that fell apart after 3 years or so...now i use brackets to hold the sides together. I will post you a picture of one when i get home from work tonight....speaking of work.....back to it.

hope this helps
