Mine are at the point where they need to be potted on. Do you plant them down to the set of leafs? What is the smallest size pot I can get away with until they go out into the allotement? I have alot of plants so am lacking in space so the smallest size the better ![happy :)](https://chat.allotment-garden.org/Smileys/green/smile.gif)
When I prick out I bury the baby seedlings up to their seed leaves. Some plants don't mind the main stem above that being burried (e.g. Tomatoes), some hate it (e.g. Cucumbers).
If I am planning to pot on (e.g. Tomatoes which I grown on to 9" pots before they are planted out) then I use 3" pots to start with, and then increase at about 1.5" a go, and then a bit more when I get to "larger" sizes - so maybe 3", 4.5", 7", 9" ...
For things that I plan to plant straight out I prick out into 9cm / 3.5" initially. The reason for this is that it gives me a bit more time before they MUST be planted out - so if weather is not right, or I'm not ready

then there is some leeway before they must be planted out.
Some things are happy in smaller modules (Onions, runner beans), and some things I plant several to a pot (actually I've now taken to planting two Runner beans to a 3" or 3.5" pot instead of one-per-module-cell which I used to then plant two-cells per cane - now I do two-seed-per-pot and plant one-pot-per-cane

I also grow 2 lettuce per pot (and cull one for salad-leaves early on) and 3 beetroot around the rim of the pot (and take two of them early for "thinnings")
Other option is to use Richy's Paper Pots made from newspaper rolled around a can. I reckon the ones I make are only 2" in diameter, but often 5" or 6" deep. I use them for things that need depth (Parsnips, Sweet peas, Sweet corn) and which don't like being transplanted (whole pot and plant goes into the soil) but you could use them - don't need that depth for most things though.
But I would avoid using pots that are any smaller - even if you are tight for space. They will just need potting on before they are ready to be planted out.
For Peppers, Aubergines, Chilles you are going to be potting on before it is warm enough for them to go out ... so I reckon you need to plan for that :happy:
