how many plants would i need to grow to get a kilo (uk guerilla)

next year i plan on growing loads of plants, any strains you would recomend also i aim to grow about a kilo, how many plants would i need to grow
any more info needed please reply with your question
p.s sorry about grammar, to tired to type properly

BTW stating the ovious but im talking about outdoors in the united kingdom, west midlands, lattitude of about 52

grow wonderwoman from nirvana each plant can get up to a half kilo if trained right and its some fire ass skunk and its only like 25 usd for 10 regular and i got 9 out of ten seeds were female and i made a shit load more seeds with the male a couple phenos one perdomantly sativa and pretty fruity skunky flavor and a earthy fruity taste and the indica was more skunky smelling with a skunk taste... a knock out stone too but keep a eye on her for mold i had a slight mold issue other then that it was pretty awsome and really heavy yielding

well if your looking for yeild, critical mass produces some gigantic buds...also if your growing outside, you could get a kilo from one plant if done right. you should get about a pound per plant outside pretty easily.

also i need something mould, pest resistant and something that will finish about september, also something that doesnt mind the shit weather, thanks guys ill look into those strains

I can do it with 4 plants, with the right strain for sure.

any suggestions for something that fits what im looking for (mould and pest resistant, high yielding, and something that is as strong as possible for commercial properties, good with cold, wet and unpredicatable climates) cheers people

i just started a northern lights x big bud i know big buds is a pretty good yielder alot of breeders cross with that or critcal mass for yield and i know nlxbb is pest and mold resistant

southern slope, no shading trees and a mold resistant strain you do the research.

1-4 plants depending on genetics/nutes/pot size

I grow some origonal grand daddy purple clones, purple urkle crossed with Big bud, holy fuck does it yield... tips the charts at 1Lb under a 400w haha.
