Heated seed trays (Brasenose OX11)

Two Stewart brand electrically heated seed trays for germination of seed, either sown directly into the tray or in smaller pots. The green one has a 12 watt heater on the black one is 8 watts and they run off the mains. The lids are not the original ones as I can’t find them. I have tested the resistance of each and the heating elements work with the correct resistance for the rated power.
