what seeds should i use

I live in the west midlands of england i want to grow outdoors but i have never even seen a weed plant with my own eyes so could anyone help.
I need something that i can plant outdoors from seed, it needs to:
yield at least 300 grams per plant, discreat growing, and if possible mould resistant.
also i need 10 seeds for a maximum of £20. i need a internet link,
THANKS GUYS

try this links but first you must realize three things-
1. you will never get a 300 gr per plant! thats crazy! the most u'll get is 2-3 ounces (60-80 gr).
2. mould problems accurse because of bad maintenance. you get w/the seed 10 free seeds to practice. use them.
3. it is almost september, the days are getting short. if u plant seeds now, taking they do have enough sun to grow, they will not have enough time to veg and your yield will be small.

if you want discreet- go for indoors! then you can plant when ever you want to.

ive been told very bad things about amsterdammarijuanaseeds.com

LOL

good luck with your endeavour
