Thanks for all help up to now...
A trustworthy source told me if he put the right plant in my back garden and looked after it properly he could get a KILO from it. This completely blew my mind and i want to get 6 or 8 underway, i aim to have 4 or 5 healthy large plants when i come to harvest. A place to grow is the most serious problem, in a couple of weekends im guoin to go check out some lovely northumberland countryside see if i can find somewhere suitable
How much per plant did anyone who has grew outdoor before get??

Yeah Blaze, out your addy up and ill add you mate
