ABSTRACT:
Collars, for supporting plants by the base of their stems with the major portion of the root structure extending downward into an aqueous hydroponic medium, have upstanding sidewalls and bottom end structures that support the plant while leaving at least about 75 percent of the bottom area open for the roots to extend through. The collars are very small having a volume less than about one tenth that which would normally be considered adequate to conventionally culture plants in a solid support medium. Vertical foils extend radially inward from the sidewall to prevent the roots, in their early stages of development, from spiraling around the sidewall.
