The instructions on the packs all tend to say germination times up to
some months. Is it correct that it should be OK to keep the seeds in
their pots/trays in a 'sealed' plastic bag for that long?

Not if the plastic bag is not clear - some seeds are likely to germinate
earlier, and they'd need light. There's also more chance of damping off
if you leave them in sealed conditions.

The bags I have in mind are large 'sandwich' or 'freezer' bags from Tesco.
They seem fairly clear, so will these be OK? My plan is to either use ones
with a resealable opening or wind the opening together and hold with a
tie-wrap.

When I'm not using a heated propagator I cover the "trays" (recycled
plastic ice-cream cartons) with clingfilm. Then one can see when the
plant have germinated.

I've noticed suggestions to use cling film. However I wasn't confident this
would continue to grip and remain sealed for a number of weeks when in the
presence of damp contents. Is it reliable? The Pontentilla and some of the
other seeds specify germination times of 1-3 *months* so I am concerned
that this may be a long time for the bag or film to contain the
air/moisture.

I'm also planning to use some old ice-cream cartons as the outer 'trays' to
hold a few of the 'peat pots' in bags. :-) However I am hoping the linked
sets of 12 square pots I am starting with will be OK without the ice cream
box. I'll know better once they are filled with compost and soaked. :-)

Slainte,

Jim
