as others have stated, too many variables starting with one's own definition of 'decent quality bud'
Until you can qualify that threshold or meaning that everyone can agree on,
there is little chance anyone will be able to quantify the answer you are looking for.
Good luck with your quest
Well the worse the weed the higher it costs. Pesticides, excess nutes, too many employees, ruined/no flavor when vaporizered, thats what makes bud unacceptable. We all agreed on that until legalization started peddling to non-weed users, now "acceptability" is strictly about looks.
I've bought kilatons of weed through the mail in my life, the quality started dropping dramatically once the digital camera was invented.
