Hi, Constant....the name seems familiar.
Without seeing those instructions in detail its not easy to make a reasoned reply....but first thoughts are just waffle.
First of all it isn't necessary to soak the seed, alas, if you have already done it, it will do no harm.
Your seed will require a maximum of 10c (50f) to germinate after that they will cope with temperatures as low as -10c......any form of warmth is solely to initiate germination.
For me, no propagator or plastic bag.....and misting!
Plan 3 seems your best option.
Btw, you can always ask questions on the other thread, if you can't find what you need.
