Building another one of these today, I built one early spring and it worked really well for growing lettuce/greens in, I have it packed with peppers at the moment with the plastic off.
The cedar for the raised bed, the boards to hold the plastic and the pvc for the frame cost me about $80 at Lowes... It's 4x8'.
I've since replaced that 10ft board that was holding the plastic with an 8ft one.
Here's where I took the idea from, I'll try to get a list together of everything needed to build one of these if anyone's interested. I'm no carpenter or handyman and I can throw one together pretty easily.
I put down a layer of cardboard at the bottom, a layer of sticks and then a layer of half composted leaf compost, then about a 6" layer of cheap bagged topsoil and topsoil/manure.
Lettuce seemed to grow twice as fast as it did in the ground.
Lettuce/Kale/Tomato and Pepper starts
10 days later...
