I do the same way but with seed you need to put it in the shade. It is more likely to grow that way. I try putting it out in the deck and water it everyday before and it seem that I have more dead. Come to think of it I only have 1 out of five seed that made it.
Try to put the pot in the shade and wait until the seed spout and become a little more mature before putting it in your deck. If you have no where to put it try sowwing it indoor before bring it out. I put mines in a water bottle fill with soil and let it sit next to my window.
Mimosa or Silk tree (Albizia julibrissin) seeds are fairly easy to find and grow. Try the seed exchange forum here at GW or collect some of the abundant pods they drop or check online for a source.
Soak the seeds in warm water for 2 days or so. Some suggest scarification, but the soaking should be enough. plant in normal potting mix. be aware this tree is considered invasive by some.
When I lived in Phoenix I would just go to the park and pick some up of germination experiments. Gardenweb has a Gardening in Arizona where you might locate someone to do the same for you. My experience was that you get better results from fresh seed, late summer or fall, and you get better results scratching them with a nail file. But the seeds do germinate rather well when a year or more old and just soaked or planted.
Logan, being F1 hybrids won't prevent your Rocket snapdragons from going to seed--in all likelihood they will set seed. What it will prevent is knowing exactly what the offspring of any seed you save will look like, in the same way that a child of parents who look different from each other may look like a little like one or both parents or neither. Unless there's a plant patent or other prohibition to saving seeds from a hybrid, there's no reason not to experiment. They should be snapdragons and they could conceivably be similar to their parents.
Sure, you can get seeds of open-pollinated snapdragons that you can grow and save seeds of and grow again. Thompson & Morgan has quite a good selection (check the genus name Antirrhinum and look for those that do not say F1) and Select Seeds has a few and so do other places.

An easy way to tell if you overfertilized is if the leaves are curling under or over. If they curled under, then overfertilization is a probable cause. Growth can be stunted but usually if you catch this in time, the plants can be salvaged.
If the fertilizer is a slow release kind, you probably want to repot with fresh sterile soil.
Overfertilization = dehydration, as the strong ionic solution the fertilizer creates sucks moisture out of the root hairs, rather than visa versa. Re-potting and thoroughly wetting the new soil as soon as it shows signs of a fertilizer "burn" can sometimes help.
When I start seeds, I put them on top of the fridge then anytime I'm using the clothes dryer I'll put a container of seeds on top of it to sort of give them a boost. Most seeds have germinated rapidly doing this with a high germination rate except for my Rosa Bianca eggplant and California Wonder peppers. Both were 0% germination.
They should do just fine, if they had a litte bare ground they would re-seed themselfs.
