I'm in as long as it's from seed. Clones in my area are not easy to find, ordering them or taking them from your own plants is about the only option.
As far as medium, nutes, and photos/autos I say growers choice. If it's a competition to see who can grow the best in the 1 gallon pot then growers shouldn't be limited to a certain medium, nutes, or autos/photos.
I just don't think it's fair to take someone who grows with synthetic nutes and say now you need to use organic now, people who grow organic already would have an advantage.
Plus people are always like organic is better or synthetic is better, soil is better or coco is better, or photos are better or autos are better....I say put your money where your mouth is and let's see who can grow the best in their own style.
Also only 1 plant, no starting a bunch and at the end picking the best.
Oh and if we do this, I'm growing it in the middle of house somewhere because I'm not giving up tent space for a 1 gallon pot lol
