Plug tray with removable modules.

30x30mm at the top and hold roughly 25ml of grow medium, 14mm drainage hole to make it easy to remove plant from module.

Two versions of the holder a 3x3 (uses 4 legs) and a 4x6 (uses 5 legs), with two lengths of leg, the shorter ones let the modules sit on the surface to maximise heat transfer when used on a heated mat and the longer leg holding the off the ground allowing roots to air prune.

This has been designed specifically for seeds like Chilli's that require heat for germination, allowing germinated seeds to be moved off the heat while leaving non germinated ones where they are.
