...if I was going to grow outside....no matter where it was...I would use big pots......but that's just me...
Big pots are definitely the way to go.
Why ?

I've been an outdoor grower foever and always made a 2/3 to 3 feet hole putting pure sheep crap in the bottom and filling the rest of the hole with Pro Mix. I use the HEAVY HARVEST food from Advanced Nutrience for the entire summer and add some bud blood, big bud and overdrive from august to end of october (depending on strain) and always get great results !

If growing in pots will give me bigger yield and an higher quality harvest, PLEASE SHARE THE WISDOM ! Would't growing in pot be more work as you would have to water them yourself all the time ?

Thanks for your help.
