So I was watching one of my favorite marijuana growers channels on youtube, brown dirt warrior, and after his plants had reach the max size for his pots, he had dug a hole in the ground and filled a compost garbage bag full of soil to put his plant into. Also adding that he used the lime nutrient and some other of his preferred plant food. Would a garbage bag be a convienent, cheap, and useful method for an outdoor grow? Any comment would be greatly appreciated.
