and thanks for your service. Disabled vet myself....if I may put in my two cents...
I grow in promix hp (around 25 bucks a bale, I go through two bales a year on average), and in 5 gallon soft pots. I use greenleaf nutrients (budget friendly, easy to use, plus they'll give you a free sample of their megacrop), and grow under auto cobs (made in the USA). I used to grow in a 4x4 tent, usually 4 or 5 plants at a time (in a 5x5 now). This is a pretty easy grow style to get the hang of....
I hope you get things figured out soon, and can experience the joy of growing this amazing plant. Personally, I like to have a few indica and a few sativa strains around....you can get a pretty good tolerance build up if you are using the same strain all of the time...at which point the therapeutic effects start diminishing. Let me know if you have any questions or need help. Cannabis absolutely works for the things that ail the military body.....I use it solely to treat the things that need treated, and was able to get away from all of those pills the VA pushes. Good luck, bro.
