Can vegetables like radishes, squash and lettuce grow in sand?

Pure sand has excellent drainage, but without other minerals or organic matter it would have practically no nutrient holding capacity. Technically the plants you mention will grow in sand, but you'd have to apply water more often and feed them frequently to make up for the missing nutrients. It would be similar to hydroponic growing, in that the "soil" would be considered inert, and you, the grower, would have to supply nutrients on a regular basis.
