Well here I am NC420, and from what I can see you have done your research it seems. After you have seeded your soil or medium rake the medium lightly to slightly cover the seeds (about1/8 to 1/4 inch) or you will end up with very delicate plants that will sit on top of the soil rather than grow into it as much The only advise I would give for growing inside is to be extremely carefull about mold during germination. Some people will want to cover the soil with plastic to keep the moisutre in, this is a no no because of the molds that can be carried with the seed from production. Many say to start in peat pellets indoors, but this too can lead to mold situations if you don't carefully monitor the moisture and temps. The thing to remember is that some types of poppies can take up to a month to germinate (at least 7-14 days min) and really start to take root, that is a long time for stagnate water to be saturating the seeds and soil, providing the ultimate mold conditions... the best way is to leave the medium to be seeded uncovered and mist when needed (usually very often). this may seem like a lot at first but believe me it is better than losing your crop to mold before it flowers. Another way to keep the mold at bay is to germinate at a lower temperature (remember in the wild the poppies will start sprouting along receding snowbanks) so you can go pretty low. Personally if I want to grow poppies indoors (harder than outdoors in my opinion) I germinate them outside in the 35-50 degree F range and only bring them in once they've taken good root and are showing signs of first real (lettuce stage) leaves after the cotyledons. This provides them with natural ideal germination circumstances. Then once they've grown up in what seems a harsh environment, when they are brought in they thrive if not over watered...
I feel as though I could write a book so I'll shut up here and see if any of that helps and if there are more questions...
Hope this at least gets you started.... BTW is there a reason you have to grow inside besides the law?
