Abstract

Improvements in the constant-level head devices intended more especially for hydroculture apparatuses are characterized in that they comprise practically a provisioning chamber which is in communication with a utilization apparatus a constant level tub of substantially smaller capacity whose feeding conduit is controlled by a float device and between the aforementioned supply chamber and the aforementioned constant level tank, a step whose diameter is calibrated or calibrated.
