It's worth nothing that @SpikPT is in prohibido-country so large plants are probably not advisable. The reason N. Californians recently took to the big outdoor plants was to comply with the original 1996 MMJ rules allowing 6 mature or 12 immature plants with no restrictions on yield.
'Jorge Cervantes' Green Giants of California (still available on youtube I think) was my inspiration to get growing my own medicine & not just supplementing what I'd been over-paying for.
My local rules prohibit outdoor () so I can't grow a truly big plant without a lot of risk; this year I hope to SCROG at least 2 of my outdoor beds & sacrifice some yield for a lower visual profile.
Back to Portugal...
