strain advise

Whats up ppl I live in australia and iam about to embark on a guerilla style grow starting in September when iam plant start of aussie super hot summer time lol
I am after a strain that can grow within 1 year 6 to 8 feet tall and will produce 3 to 4 pound per plant lucky for me australia summers r hot and we have some of the highest uv ratings in the world so I think if I plant in the correct area full sun good water I should be able to do this
So after a strain mediocre strength and big yield

Wonder woman nirvana seeds
Pure power plant nirvana seeds

Not a fan of either of the strains listed above.

What you are looking for is basically what everyone is looking for... the holy grail of yield, potency, size, stress resistance, etc.
Good luck finding it. I would suggest something that is Skunk based.

Super sour skunk-hortilab
Xj13 x Appalachian-bodhi
Bikerkush, sour jack-karma
Fuel, cheesedog, ecsdh - connoisseur

OB x NL#5, it's been awhile
The 3rd Dimension....my new favorite(for the past 2 years)
