I made these with the idea of growing carrots i wanted something i could make quick and dismantle and put away for the winter.
I've grown carrots and potatoes with good success when harvesting the potatoes i just lifted the frames of and picked the potatoes from the soil..
Step 1: Cut Side Pieces
decide how wide you want the planter and cut the side piece so it fits inside the 2 lenghts and then cut a thinner piece to match the outside width.Then screw or nail the two pieces together to look like the second picture. Make 2 of these and attach to the long lengths as in picture 3.
Repeat and add to the first layer and so on till you get the hight you want see picture 4
Step 2: Finish of With a Top Edge
Finish of with a top edge and line out with plastic sheet fill and start growing
