(White DwarfAuto Skunk)Afghani Auto
Fast and potent auto strain with very good yields.
If you're looking for maximum yields and maximum potency in an autoflowering strain then look no further. Fast was the first hurdle for Heavyweight, taking a sturdy white dwarf and crossing it with an auto skunk that would reach its full potential in 7 careful weeks, and then the Vast came when further crossing with a powerful Afghani auto. Great care has been taken to ensure that the high yields are not at the expense of quality, the long thick buds covered in sparkling crystals produce a high quality soft and sweet smoke with spicy undertones. The effect is very fast and knock out, leading to a long relaxed stone.
Don't expect Fast and Vast to perform like any ordinary auto, for this is no ordinary auto, it's a Heavyweight Auto!

good seed, but does not suit my needs.... an autoflower seed is better for my greenhouse...

Good smoke after a 12hr shift. Puts you on the couch and sleep like a bairn. I got 3oz a plant in 11 litre pots with Allmix & a 600watt HPS and didn't really take care of them, just watered every 3 days.

Very fast. 55-60 days to first cut. Let the bottom go a little longer. Great Smell. About half of them turned out mostly sativa like and the other half more indica. All nice though, no complaints. Fruity , terpine filled smell.

Fast and Vast Auto Feminised Seeds
Had 3 of these. They literally germinated in a couple of hours. All 3 to begin with, but when potted one of them struggled getting its shell off and went know where fast, so we pulled that very early on.
Out f the two left one rapidly grew straight up and started flowering really quickly. Finished long before the other really got started. We had a harvest from it but not much to shout about, but w did no LST or other training with them at all.
The second, late flowerer,, was looking superb, huge amount of bud sites, but unfortunately a visitor boughht thrips in with them and we had to pull and treat our others..
Lovely smoke, and will try again, might try something else from this breeder first though.

Fast and Vast Auto Feminised Seeds
Amazing, I now only grow fast and vast or green crack autos. My yield with the fast and vast is bar none. I'm currently using 100% soil less mix (perlite and perlite only) My plant is currently 4ft 6in at day 49 and its being grown with two small Mars Hydro 300's. The fast and vast genetics by heavyweight seeds is beyond forgiving in my opinion. I only have a few grows under my belt and I've done some stupid sh#$. These plants have seen temps over 90 deg. , humidity over 80%, grossly overwatered (that is why I switched to perlite, I cant stop messing with things), bugs, ect, and if you walked into my room and looked at her you would never know it, she looks and smells absolutely beautiful. Germinate and harvest correctly and you cant go wrong with these genetics.
