Hi kimlien, not ever heard of the jiffy 7 pots before, but on having a quick look at them I can imagine it might be hard to keep control of the moisture levels.I used some similar( I think) biodegradable pots for some lobelia seedlings, can't say that I was that impressed. Sometimes they seemed really dry and others too wet. Slugs laid their eggs in them, so won't be using them again.
As for labelling, another poster suggested if you have loads of the same seedlings going, colour code it with a piece of coloured straw. I thought this was good idea as it saves labelling every pot.
I would follow the advice on the seed packets re light. For a lot of seeds the advice is generally the same ie sow about 1/2 " and then cover with fine compost. There are some though that are different.
