Wow! That's quite the large task in front of you, and let me warn you now, you are in for a battle, friend. Guerilla growing; I assume that means outside, in a place that you don't control completely? You're just going to go and toss those 50 seeds in the ground and hope they pop up and grow some danky? Those are high hopes, and by no means am I trying to deter you from your dreams, but I'm a bit of a realist. It's not likely that even 45/50 of those seeds will make it to germination. Of those 45 that do germinate 10 will die to random bugs, disease, etc, (if not all of them) and of the 35 that survive, half will be males, which will produce basically unsmokeable bud. Those males will also pollinate your females and make their bud shitty. Suggestion?
Get a 4 ft T5 floro tube light fixture, highest wattage you're willing to pay for. Get a 50 pack "Grodan" propagator. Germinate all the seeds under that indoors using VERY, VERY, VERY, light nutrients. No nutrients during germination and 1/10th strength until they have 2-3 STRONG sets of leaves. Keep vegging them under ATLEAST 18 HOURS of light a day until you see female sex signs. Kill and throw away anything that shows male "balls". Once they have a nice start to life, bring them outside and "turn" the soil that you are going to transplant them into. If you want to be a real badass about it, get a bunch of H2O2 (hydrogen peroxide) and soak the ground where you plan on transplanting them 72 hours in advance. That'll prep the transplant zone for a healthy start with low chance for infection. Hope this helps!
