I would also like to hear people thoughts on the 2F2V by Heavyweight. It says on all write ups I have seen that it is roughly a 56 day, or 8 week strain - like it's predecessor the Fast & Vast, however I have seen some of the grows of the original F&V needing a week or two extra at like 10 weeks. In fact a lot of the write ups for Heavyweight autos say approx 8 weeks, wondered if anyone has experience of Heavyweight autos and the general lifespan of them?
