I've done both and haven't really noticed a difference but I didn't run into issues. What I mean by that is you could stunt growth witha transplant shock or with miswatering but if both are avoided it shouldn't be much of an issue.
I lean more towards just starting in the 5 gallon but that might be me being lazy. Once I had to transplant from a 5 gal to a 10 with an auto and didn't notice an issue and the transplant was less than smooth. Haha sorry I'm not tons of help. Straight to the 5 is my vote less work same results on opinion.
I've done both saw no issues but I only transplanted once. I like starting in final pot just me.Girl Scout cookie auto flower seeds. Transplanting or starting straight in 5 gallon totes?
I’m aware of overwatering issues growing straight into 5 gallons but I hear it’s suggested with auto flower seeds as long as you’re careful with watering amounts. Thoughts??
