Growing potatoes in a reused container

• I had this plastic bin that has a crack in the bottom so I decided to try to grow my own potatoes.  
• We drilled holes in the bottom and I filled it with a soil made up of potting soil, vermiculite, sand & organic compost I had left over from another project. 
• I then mixed it with straw
• I had some purple, red & white potatoes I let sit in a dark, cool closet that sprouted. 
• I sliced them up & buried them in the soil right beneath the top, then covered them with straw.

Keeping my fingers crossed!
