Cucumbers - root space or water?

[mic]

Hi

Square foot gardening states 2 cumcumbers. Is this for root spacing or because of the amount of water they need? If there was a constant water supply would it matter if I planted 4? Or wouldn't there be enough room for Roots?

Cheers

Presumably, you're going to grow them up canes. I don't think its roots or water but head space.

^^^ I agree - also you're risking powdery mildew by not giving space for air to circulate
