you'll get a better result with soilless/hydro methods..
16 oz cup can give 40-50g if you do it right and have a good genetics in the plant for yield. i'd wager your pill bottle proportional to that size is your ceiling. 10-20g, if grown well? probably need to fertigate 2-3x a day once it grows out a bit, lol.. giant pain in the ass for a gimmick. That said, i did a solo cup grow one time and i probably learned a couple things from it, i bet... i would never do it again though. just a pain in the ass, lol.
