Outdoor autoflower

All seeds cracked. Started Saturday morning, by Sunday night all had cracked, tails range from 0mm - 4mm. Place into 4 inch square pots using a custom soil mix of some shit I had in my garage, some miracle grow organic nature potting soil that my wife had left over from flowers plus some perlite, and bagged top soil for my lawn. Mixed it all up in my dirt tub. By the time of this posting, I have one of each strain about 1/4 inch tall with first set of leaves, waiting for others to start. It is cold outside so I didn't wanna check them. In a mini hot house that stays about 10f warmer than outside on cold nights
