Hi I know there is probably a more suitable section for this thread but I know my questions will get answered in this section which is why I chose to post it here

Can I use 100% natural compost, the black compost found under leaves in the woods, to grow autoflowers? Will this provide enough nutes for the grow?

Can I use 2 gal trash bags?

What would be the best method for starting autoflowers starting in small pot or planting in final pot? Final pot may possess a challenge as we are still having nights temps in the 40s and 30s in the near future so I will have to start the first few weeks indoors

If possible I would like to know starting pot size, at what week/size/development stage I should transplant at, what size pot/trash bag to transfer in/final soil combo I have dry nutes I can use or liquid if I want to water nutes in just trying to figure out the most efficient process. this is my first time doing auto and my first time growing outdoors
