I have a Card in Oregon, and the law is under 12" and no flowers in inmature. I am getting ready to start my garden as soon as my seeds arrive. I am have no problem following the law with 6 mature, I can get at least 5oz per plant, so why not? But a guy I was helping at his residents (he had MS) he had me growing 14 clones, 16 veg (6"-24") and 12 in flower. All at one time. I quit being his caregiver/grower because he wanted me to go as high as 90 in the flower room. Dude was insane, and cheating a good system.
