" Huge crops of potatoes can be gained from one tuber by the dustbin
method you describe if the plan is carefully followed. The plant tops
need to be kept showing above the soil surface, so earthing up needs to
be done in several small stages, taking the soil up to the neck of the
plant. Some additional light will be needed in daytime when they are
trying to grow at first in the lower part of the dustbin and a minimum
growing temperature of about 10C/52F needs to be maintained at all times
for protection - higher for continuous growing.

Our area has just gone over to wheelie bins. I've just bought a few seed
potatoes to grow at school. Maybe calling on neighbours to ask for their
old dustbins might be a good idea ;-)

I gather holes need to be drilled in the bottom to allow for drainage?
