Fat Bastard Auto DIY Shed Grow (First Time Grower)

Hey guys, this will be my first ever cannabis grow. I got 3 Fat Bastard Autoflowers from Canuck Seeds. The grow space I'm using is a repurposed storage shed, and to save money we didn't buy a tent or an inline fan and instead spent the money on a bigger light and whatnot. The medium I used was potting soil with organic matter mixed in from the hardware store and Gaia Green All Purpose and Power Bloom premixed into the soil. After putting the seeds in paper towel, they all split open and were able to be placed in the soil after about 48 hours.
