New grower med patient looking for best GG4 autoflower

[Upnorthlion]

Greetings all, I have one whole grow under my belt. 3 plants of Bruce Banner auto netted me 2.4 oz dried. Anyway I have found GG4 to be a great strain for my medical condition. I have also tried different tiers of GG4 (they grade by THC here in Michigan). The higher the THC the longer it helps. The higher the THC the more it costs. However, being on a fixed income I can’t always afford my medical cannabis bills. So I have decided to grow my own to save some money. Who has the best genetics for GG4 autoflower seeds in your opinion? I want the good stuff
