marijuana growing help!!!

m just starting to grow my first plant from one seed i found in some grade A shit. I know that being able to succesfully growing weed from one seed could be a slim chance but ive already germinated it and planted it so i just hope it ends up being a female. So because i cant grow in my house im just going to transplant it in a 5 gallon bucket and put it in the woods some where. But i have a few questions about growing.
1. how big should my plant be before i transer it to the bucket?
2.Is it alright to use mirical grow?
3.since im not going to be abe to dry it indoors i was thinking of making a big like box out of wood and hang the buds upside down and maybe get a shit ton of those mini fans and a shit ton of batteries to put in there to and there is only going to be one plants so i really dont need much. Do you think that could be a good idea?

in 3 weeks my plants about 6 inches tall and is growing its second pair of jagged leaves. is that good?

Its best in my opion to plant directly into the buckett/pot it will finish in but you can transplant it any time you want just be carefull with those roots. I never use mirical grow but it works for some people ive found it to be a little hott for my girls I use Fox Farm Ocean Forest and Happy Frog. Ive never tryed drying/curing outdoors but I guess it could be done but I wouldnt use fans they will dry it out to fast and leave you with that grassy smell, a good slow dry is the way to go. Hard to tell how good it looks so far without a picture. Good Luck!!!
