Ya grow in the yard. sneak in some seeds when you get you go outside for recess plant them along the fence or on the other side of the fence. Use bananas for potassium and you need something for phosphorus and nitrogen. O add some water to your piss for nitrogen.
(Ok Since im tired of all the fucking haters)
OVERVIEW
I agree with irie here. Your only chance would be to grow outside in the yard. Your going to need to sneek food scraps from lunch to fertilize your plant, anything will do, and you could potentially start a compost in your own toilet, under your bed, ect, keep it enclosed in like a ziploc bag or something so the smell doesnt get too bad. And yes, you CAN compost in a ziploc bag. urine would work great as well, just might look kind of obvious that your pissing on your plant in the corner everyday,so put it in a water bottle or something. OR if other prisoners are pissing in the plants anyway during recess, GO FOR IT! take a crap on the plants while your at it.
COMPOST:
This is NOT completely necessary, as the yard soil may just be good enough to grow your weed. But is a great way to keep your plants growing nicely.
AS I mentioned before, you can compost in a sort of bag like thing. Sneek bits of scraps after lunch everyday into your cell, and collect them in a plastic bag and hide it well. Theres a variety of options, flatten the bag and put it between your matress and frame, under the bed, flatten it and just put it in your sheets, in your matress. IF you have a cool roomate, compost in your toilet. Then just transport small amounts of this compost to your little grow in the yard every now and then.
OR you could just sneek a few scraps oiut to the grow site itself, and throw them next to the plant. The nutrients will eventually breka down into the soil, but composting is a better way to give the plant what is wants.
STRAINS:
Ill just say it now, youll HAVE to choose one of these two strains to in any way possible grow in prison
As far as strains go, your very limitied, but when your growing in prison, this advice will be the most help you can get.
Either get a lowlife autoflower dwarf, go online and find a seedbank that sells them and get some of these seeds. They are stealthy,and could be easily hidden amongst the plants in the yard. They dont grow taller than 1 and a half feet.
OR, better yet, find this strain

This plant, even if found by somebody, could look like some strange sort of regular plant. Perfect for growing in the prison yard.
HINTS:
Take this advice, youll need it.
HINT: befreind your roommate. A good trustworthy roomate could make a great growing aprtner. Let him know what he is in for, and make sure he doesnt tell ANYBODY else. You gotta form a good relationship with a prison mate to do this, if you cant form a good freindship, dont ask for his help, DONT EVER LET HIM, OR ANYBODY ELSE KNOW THAT YOUR GROWING. hopefully he isnt a huge black guy that will make you his bitch. Usually those are just seriotypes, there are guys like this in prison, but the chances youll get one for a roommate are null, from what ive heard, most guys get along with their prison mates as long as your both cool with each other.
HINT: Like I said earlier DONT EVER LET ANYBODY KNOW THAT YOUR GROWING. Word spreads liek wildfire in prison, and youll be finding a dick up your ass soon for that weed if word gets out.
HINT: BE a sneeky little jew. Hide that compost well, ( under your bed, in a ziploc, ect) dont make it obvious your putting scraps in one section during recess everyday.
avoid patterns. water it every other day. Still play basketball with the guys, be cool and dont be an outsider in prison, it will only attract attention to you.
Hope this helps, if you have any more questions feel free to ask.
more power to ya buddy, growing in prison is a big feat, but it can be done.
