Outdoor grow questions (first year grow)

Hello i'm new here but I've been liking for awhile now. I have a few questions about growing outdoors. First off I am ordering Alaskan ice (ww x haze) and afgan kush from attitude seedbank. I will have 8 feminised seeds. I am growing in moutainous area but in rubbermaides. how many plants could I fit in each rubber maid. I am unsure of the exact dimensions of the rm but I will be using the same size as people have used for inddor grows except they stacked 2 on top of each other. I also have a stream nearby but I am nervous that the water will contain chemicals. How can I be sure the water is good. Is there an organic soil with time release fertilizers and should I add different fertilizers during the flowering period. I want to try to stay away from chemicals as much as possible. Finally I was wondering what natural things I could do to protect my plants from insects and pests. Basicly I am trying to plan everything perfectly to get an ideal crop to last me and my homies til next year cause it's 60 for a slice of dankkk that's a lot of money to be tokin daily. Once I start my plants I will star a grow journal. Go smoke a bowl haha peaceee

if you are using the standard rubbermaid containers.. Only one plant per container. A general rule when growing outdoors is a plant every three feet

just put them in the ground without pots or containers they'll grow better
