I have a Fastbuds Gorilla Glue planted on May 24th. Just started really growing about 3 weeks ago. Two weeks ago it started growing 2 to 3 inches a night in the tent. One night it grew 4 inches by morning. I had to move it outside as it got to tall and I would have to move my lights higher than I wanted for other plants in the tent. It was at 40 inches. Now at 44 inches and started flowering around a week and a half ago, now covered with buds and leafing out. I posted pictures in another post today. It was planted in an undersized pot with poor soil. It is growing like crazy now.
I've got several other Fastbuds strains going and they are all different for me, some short and fast to finish. Others getting real tall and taking much longer. My Gorilla Glue seems to do much better since I moved it outside.
I've got some other breeders autos, Afterthought Autos, I planted back around April 15th that still aren't ready and others I planted on June 1st that got about 3 inches tall and just stopped growing. I moved them outside and by the end of June got no bigger and was tempted to pull them and not waste my time. In the last two weeks they shot up to 3 feet and are packing on the buds. All of the autos from this breeder are said to finish in 85 to 90 days.
I've planted several Fastbuds Fastberry and can't get most of them to grow more than a few inches, but then two planted in the exact same Happy Frog soil as the others are doing fine.
