You can harvest everyday if you so plan to. Not that it would make much sense. Personally every 3 weeks sou ds nice for payin bills and not getting to bogged down with trim constantly.
Sounds like fun! Wish i had my own setup like that.
8.11 per gh with veg area seperate with the right awesome strain and either blackout curtains or an blackout area ,,,,,,yeehaw..assuming heat and cooling /co2 settled
I use to do 3 pr year in north europa and boy it was a big job.
I know some pepol in spain do 4 pr year and the winter-fall crop they suplement with extra light.
Last location i rocked, we just did 1 huge long veg, monster plant only yeild half of what 3 runs would but it was so much more easy. Setting up trimming and harvest 3 times pr year was so damm stressfull. No time for familie or golf =) =)
