(b) living and harvested cannabis plants shall be assessed by square footage, not by weight in determining the amounts set forth in section 11300(a);
(c) in a criminal proceeding a person accused of violating a limitation in this Act shall have the right to an affirmative defense that the cannabis was reasonably related to his or her personal consumption.
the law says that if you grow a plant that has more than an ounce, no big deal. you can simply harvest an ounce and leave the rest as a 'harvested cannabis plant' within the confines of your 5x5 area, as it will be assessed by square footage only.
if you do not want to do this, and the imaginary people who will conduct random searches to assure you are compliant (LOLZ!) catch you with more you can simply argue that it was 'reasonably related to personal consumption', which is easy to do as long as you are not clearly carrying selling amounts.
nice try at scare tactics, though. might want to stick to reading the bill and not trying to scare others into voting for more cannabis prohibition.
