I'm not a huge TGA fan, but several of their crosses are very fruity. I've seen subcool discuss his love of fruity tasting weed, so I think that's a big factor for them when selecting parents to cross. Jillybean was straight up orange creamsicle, and Cheese Quake is a delicious grape/cheese flavor. Having said that, I find most TGA gear to be a little lacking in the potency/effect category.
I ran Jillybean twice, and agree with your description. The first was more tasty / less potent, the 2nd less taste, better potency, and huge yield. If you want Lime Slurpee [ lime is a fruit, right? ] and good potency, I've had 3 out of 4 Chernobyls that delivered.
Huge yield, for sure. Cheese Quake is a very generous yield too.
For me it would have to be BC Blueberry from bcseedking, which I believe is the same blueberry from peakseedsbc. No proof but I think they just order from peakseeds and resale. Anyway a very sensitive plant to grow but the smoke is so good and taste just like your eating blueberries. No shit, honest as can be, strait fresh blueberries. No muffins or anything like that but the fruit itself. 2nd would be jack33, pineapple all day, did throw out a nanner or two but no seeds and good smoke. pics of BB nugs. Cant find the jack33 pics., sorry.
