The ROOT!T large propagator tray and lid are not only great value; their lightweight design means they have many uses.
The lid has two vents for humidity control, and the whole lid can be used as a large cloche when growing outdoors.
The tray has been designed to be large enough to fit a ROOT!T Propagator Tray Insert, a whole SBS tray (Cultilene/Grodan/Jiffy) or used with loose growing media as a seed/hardening off tray.
