GG Auto, Organic Amended Coco

I'm excited to grow my first autoflower ever! This was a late night impulse buy so I decided use up some coco coir mix I had sitting in the corner. I plan on amending the Coco with organic dry fertilizers/amendments and then top dress every after. I havent decided what I'm going to use but I probably pick something that's readily available and cheap lol Week 1, day 1: The seed has been placed directly into the Coco. Its was lightly watered and I used a sandwich bag to help with humidity. Now we wait.. Day 7: There have been no signs of germination all week. I dug up the seed to find it dark and unopened. A new seed was started in a rockwool cube and hopefully this one sprouts. Out of five strains and maybe 15 seeds, this is the first that failed for me from growers choice.
