Potyard

They are illegal in the US but I think Amsterdam tolerates them.

As far as equipment, I would assume like any garden, you would need soil, seeds, fertilizer, and perhaps grow lights and of course H2O.

hi friend, I have asked about the potyard in power plant....not in garden...hope you would have seen I have posted undder Electrical..anyway thanks for your attempt

Since you're posting under electrical i assume you are reffering to pot head yard?? If so , it refers to the arrangemnent frequently found at a power station, where the cables from underground are terminated on some insulator, and transferred to overhead lines.
