simple answer?

hi all, i just want to ask a question, how do i grow cannabis plants?
im in the uk so the weather is good this time of year and am thinking of growing, i know how to keep a plant alive but not a clue about cannabis.
im hoping to grow it in my garden, but can i just leave it there? or do i need to cover it at night?
also how often do i need to water her? once a day, twice?
i just need the simple rules of growing, without all these big words, if u no wot i meen,
if you can answer my question can u just use simple words, as in stem for the stem or bud for the bud, as ive noticed there are some other names for these but dont have a clue what they are, lol.
so any tips would be great, how long do they take till i can harvest them, and once they have been harvested, what do i do then? uno do i hang them upside down or what?
and also uno these sites out there selling seeds, can i trust them with my bank card details? any reccomendations? what weed id the best to grow?
i prefer the sweet ones, uno widow and haze, stuff like that.
i hate the stone i just like the high.
thankyou for your help and cheers for reading my story, lol!

Your question is answered in the link in my signature, and in the outdoor grow tutorial stickied at the top of 'outdoor'.
Cover them at night only if a frost is predicted.
Only water in times of quite dry weather, which I hear is not common in your area ;) Plants like to dry out a bit, but not to the point that they wilt. You will get a feel for this. IF you see the old lady down the road watering her rose garden, run home and water your pot plants. If you see her spraying for fungus, do the same. Oddly enough, roses and cannabis require very similar treatment outdoors. They suffer equally from powdery mildew and bud rot problems caused by wet weather and not enough morning sun.
Harvest in fall. That is covered in the link in my signature.
Don't give your bank card info unless you really enjoy serving afternoon tea to the town constable. Send cash instead, or a money order. Have the seeds sent to somewhere else other than your home.

thankyou for that, also we have been speaking to a few friends and they said that as we have already lost the amount we have then we will most probably loose all of them, is this true?
