How to grow 100 pounds of potatoes in 4 square feet

I always look for ways to improve my gardening efficiency as I don’t have a big yard. I grew potatoes in the last two years. They are really yummy. And it is easy and fun to grow them. The problem is that it takes a lot of space to grow them. Not anymore after I found this approach. You can literally grow 100+ pounds of potatoes in a 2x2 feet space. Excellent idea.

Materials,

2x6'' boards of 8 ft long… 6 pieces

2x2'' board of 12 ft long… 1 piece

2 and 1/2'' wood screws… 96 pieces

Tools

Screw drivers

Saw (optional, you may get your boards cut at the store where you buy them)

Here's the video with all details...
