Red Dahlia, get a plastic bag put some soil in the bottom and drop your bucket in the bag. The potato's grow on the Haum which is the bit that grows out of the seed potato, you earth up to stop light getting to the new potato's and turning them green, never eat green potato's as they contain Ptomaine a deadly poison.
You can now earth up your potato's until just some top green leaf is showing, they will shoot up so earth up until flowers show then let them ripen remembering to water well once bagged up, a couple of slits in the base of the plastic bag will let the excess water out.
Watering, keep some of your large pop bottles, before you go away water the plants well, fill the pop bottle with water then either drill a hole in the screw cap and upend it in the plant pot or put a material wick into the bottle with the screw cap off and upend it in the pot, the water will seep out when the compost dries and lets air into the water, if the soil is wet the air cannot seep into the bottle releasing the water.
It works on hanging baskets too.
