@Appelmoesje @givenup Just don't ever try the infinite potato cube. It's a meme and it's fake. You can add potatoes in two or MAYBE three layers but not 15. Once you force them to grow longer stalks, you're taking energy that would've gone to making bigger and more spuds, and you're taking room in the soil and accelerating the nutrient ∆. Straw or hay bales are a good alternative to bags for spuds. They hold moisture really well and you can plop a bit of soil and fertilizer in there to accelerate if needed or just set it on grass (it'll kill the grass and dig down).
