Guerrilla Growing

well i would really like to start growing within 2 weeks but i dont know if i should do it..

i would like to grow in a canyon near my house but there are a couple problems..

1-the canyon is not that big so i go to the most remote part of it but still some problems.
2-NEAR the remote part of this canyon there are some BUMS who i believe are illegal. i checked out where they live and it seems like its not been in use for a couple months. i still believe that they will use it one day.
3- i have a couple spots to grow but somthing is always missing..

1st spot-everything perfect but at the end of a trail
2nd spot- hidden from humans but not much sunlight

4-one one side of the canyon is an apt complex and on the other is a freeway.now im also worried that the people who pick up the trash from the sides of the freeway might find my plants and cut them also..

You should water once a week, overwatering kills more plants than it helps. For the first 3 weeks check the plant once every 3-4 days. It sounds to me like the location is not secure, if there are signs of human life such as clothing or wrappers it is a poor location to plant. Remember, you will be going here actively, sometimes at night. If you plant is visible, it will be stolen. Furthermore, I would not pay much attention to strain, except for the flowering period, most plants are suitable for outdoor grow, unless you have cold outdoor nights (40f and less), in which case you should plant indoor for the first 2 weeks.
