Hi ritug,
From my own experience, snapdragons need high light levels while growing indoors or they get so leggy that they eventually break. You could use fluorescent lights, or maybe expose them to a south facing window where they can get some sunlight.. in a week or so they will look better.

You can transplant both the petunias and snaps to separate pots when they have 2 sets of leaves, but be careful because the stems of those leggy plants are very fragile.

ahhh ... the reason i quit growing from seed .. lol ... i could never get the timing right ....

you get that spring itch way to early .. and before you know it.. the plants have to go out ... and its 45 to 60 days before you can do such ... aka last frost ....

increase light as noted.. and try pinching back some of them.. and see how they respond ... both types should be able to handle that ... you will have much bushier plants .. if they make it ... experiment ....

also ... if you saved any seeds... just plant another batch .. so if these become a lost cause.. you will have another batch on the way ....

one thing i did learn .... plant 1/4 of your seeds... once every other week or so ... one out of the 4 will be timed properly ... lol

we can all get the seeds to sprout ... its all the other million variables that are hard to time perfectly .... it soon becomes apparent.. or it did to me ... that by the time i bought the lights.. the medium.. the pots.. etc .. that those 6 packs for a buck or two ... were quite a bargain ... lol ... unless you need a thousand of something .... but it was fun to dabble in the house in the dead of winter ....

good luck

yep. dabbling in the house in the middle of winter keeps me sane.

If seedlings are too small to handle, they are too small to pinch. Just handle carefully when you loosen up the plants from the seed bed. Once they are shifted to next size container, they'll begin to take off. Maybe not visibly at first as the roots are establishing. Both of these kinds are slightly pokey growers -- as opposed to something like speedy zinnias -- so the early start is a good thing. Also, being among the more cool weather tolerant, they can be field planted earlier.

Just for example, I did greenhouse runs yesterday & day before. What was already outside being hardened off? Pansies, violas, dianthus, snaps and some petunias.

shameless plug for Winter Sowing (see forum here at GW).

You won't have leggy plants.
You won't have to break the bank with a light setup and high energy costs.
You can have those 'thousands of plants' for tiny cost if you really wanted them.
You can do it in the dead of winter!
You don't have to worry about when to take them outside- cuz they're already outside!

Ok, off box now. Sorry for the interruption :D

Ditto to mmqchdygg above. My winter sown Petunias and Snapdragons are doing great outdoors. Third year doing this and it works fine.

I am using my 'mini-greenhouse' (MG) for winter sowing. I cannot have a bunch of pots and miscellaneous containers around because this condo complex is fussy about clutter. In any case putting seeds outside to grow in the MG works great.

At planting time outdoors, after threat of frost and plants have been hardened off (gradually gotten used to being in the sun outside), that's a good time to pinch leggy stems down to 4 leaves. Give them some Miracle Gro and they will develop new shoots from the nodes (where leaves meet stem.)
