I have always been curious about that as well. How the frick could anyone substantiate any growing claims unless coming from another legal grow? Me saying I pull 2 gpw in my basement using 50 bucks of nutes and electricity...well that sounds great and all, but how could any employer verify like 95% of peoples claims. What even is the baseline for a "master" grower...knowledge of grow methods, nutes, deficiencies, etc.?
idk, I do agree with the being humble about it and continuing to learn as much as you can as signs of someone I would want to do business with. Wading through the extremely wide array fact and fiction regarding growing that ye olde internet provides is another thing I would think makes you a master grower.
