I have always referred to the bunk as the trim so a simple miscommunication in words can lead to people responding with ignorant answers. If every commercial grow had it figured out than they wouldn't be hiring managers and employees to maintain the opp. Do the nutrients mix themselves? do the clones cut themselves? don't be stupid if you have a manager producing 800k in product a month you don't fire him to try to save 50k a year you pay the guy and never look back. IMO
