Green Poison F1 Fast Version: Sweet Seeds' ultra fast treat


If you are someone who doesn't like the long flowering time of feminized strains, and doesn't prefer to grow autoflowering varieties either, then Sweet Seeds has something remarkable to offer! Besides feminized and autoflowering varieties, there is a third "variety" if you will, that lies somewhere in the middle: A feminized cannabis strain that flowers ultra fast, thanks to an autoflowering parent! So you get the advantages of feminized cultivars in addition to a flowering time that is even faster than that of its original feminized counterpart. How cool is that?

Sweet Seeds did this by crossing an elite clone of their own Green Poison with a selected 3rd generation autoflowering specimen of Green Poison Auto. The result is a mix of 70% indica and 30% sativa genetics.


This strain shows the growth of an indica/sativa hybrid. She grows vigorously, flowers super fast and has an exceptional yield of thick buds that are frosted with aromatic resin. What really sets Green Poison F1 Fast Version apart is her flowering time of only six weeks although she is still photoperiod-dependent. Indoor growers can achieve a massive harvest of 500-600g/m² and outdoor gardeners can expect 500-700g/plant. Plus, the plant is very resistant to mould which comes in handy when grown outdoors. There, she finishes late August to early September.


The aroma is fruity, sweet and intense. Taste-wise, this lady is exquisite. The effect is really pleasurable and gives you a mellow buzz. Don't panic - you will not be poisoned! The name plays on the venom-like colour of Green Poison F1 Fast Version. So, what's stopping you from growing this ultra fast treat? There is a reason why it is so popular!
