do some research. you will not grow good weed unless you know what to do or get lucky. however if you are in the northern hemisphere here is a place to start. Find a spot with good sunlight. go look at the sun right now. That is where it will be this time next year. a south facing hill is ideal because as summer turns into fall the sun goes from directly above to tilted over to the south. a spot with lots of sun in june isn't necessarily a good spot in October. You arent going to want to start your seeds until spring. this will give you lots of time to read and research. check out some of the pros on here and what they do. buy a book or video. some reccomendations that i can make are that 1. you mix your own soil. 2. use maxsea nutes 3. be sure your ph is always around 6.5-7 or at least check your tap water to be sure it is in these parameters. (it wont be =] ) 4. Dig a deep ass hole, you will get a bigger plant. 5. dont use pots unless you plan to move your plants, you will get bigger plants. (i have seen pictures that prove this otherwise but thats just because they used a progressively stronger nute solution almost like some hydro plants (small root system, big plant) and they probably had to water twice a day. 6. set up irrigation so your plants never go dry. if you dont know how to use pvc and solenoid valves just do something off of your garden hose. 7. have fun. growing weed will become addicting.
oh yeah and number 8. dont get caught dont place your polant in the middle of your lawn like i have seen a member do. place it in a place where an ordinary bush would grow. in a place that wouldnt catch the eye of an over head helicopter.
oh wait one last one 9. dont get jacked! theft is very common with marijuana. dont change anything on the outside of your house. make is invisible from the inside of your yard. if need be camp in a tent next to your plants during the final weeks. most theives strike at night.
you are definitely starting at the right time i wish you the best
