Hello! Welcome to the climate! I'm not sure if you saw my post but I'm also new to the area and trying to find out about similar things! Life is different up here lol. If you find out anything be sure to let us know and I hope someone answers your question!

It doesn't sound to me like you have a good setup for starting these seeds indoors. Lots of light is the key, and without a sunny window or a pretty good light setup, the seedlings will be thin and weak. An open east or west window can provide a lot of light and may be worth a try. If you keep the room temperature down, it will help counteract the low light and make for a better seedling. Although it is fun to start your own, you can buy starts very cheaply. I don't know about strawberries, but here in Sandpoint, I would start tomato seeds around May 1 and transplant out in early June. You could start earlier if you are using a Wall-O-Water or similar freeze protection.
