Hi Darren,
My propoagating bench is full now with germinating beetroot, onions, spinach, lettuce, peas for shoots, brassicas etc. I leave most trays on until seedlings are clearly established but it depends how many new sowings are about to happen. You can leave trays on until almost ready to plant, just lift occasionally to stop roots going into the sand, and with peas this needs doing every three days or so.
In essence, I like to keep it full and use all the heat, with no particular time that is best for plants to come off, once they are germinated.
good sowing, Charles
Yes the season is beginning, and yes I have a thermostat, mostly they do. I set it anywhere between 15 and 20, could be higher for toms, aubergines but then a little wasteful of heat for calabrese etc. But the warmth is economical and gentle so without a thermostat I do not think your plants would suffer on a sunny day, it is not like a space heater. They would just appreciate a little extra moisture as the modules, pots, trays whatever tend to dry invisibly from the bottom and need watering more than usual.
I rarely cover my trays as that can increase moisture too much. Just some glass for a few days on surface sown seeds such as lettuce and celeriac. Having no cover means less messing around and gives a clearer view of how growth is going.
Really enjoying topics in forum and everyones experiences !
Have no power in gardens but in JanuaryFebruary have lots of polystyrene lids from grocery boxes of chilled broccolli etc donated by greengrocers. Mostly sow in modules but pots or trays with a flat surface place on flat polystyrene. Gives a little warmth can’t say if it works really well, but has never done any harm.
