Is it too cold to plant seeds just yet?

I have a couple of autos that are cold and mold resistant, but i think it might still be too cold.
The day temps have gone as high as 20c this week but night temps avereage around 10c.
I bought beginner friendly seeds suitable for colder climates from seed-city, the strains in particular are blue cheese auto, purple haze auto, blue mammoth auto and BCN XXL.
Should i wait another couple of weeks or should i give it a try.
The risk of waiting is that harvest will be around the same time as hunting season so the risk of them getting ripped is higher

can you start them inside under a starter light / cfl. give them 2 weeks + to get established then transplant outside.
