Sweet Seeds Speed Devil autoflowering were developed by Sweet Seeds especially for those who might not be so experienced with cannabis growing skills and, yet, would like to get a good result. Speed Devil are a cross of the best autoflowering varieties that can be cultivated at any time of the year, since the beginning of their flowering doesn’t depend on the light cycle.
They are ready to be harvested already in 60 days after cannabis seeds germination produce large yields of very resinous and aromatic buds with a powerful narcotic effect.
Speed Devil cannabis seeds are extremely easy to manage. Possessing autoflowering genetics, they produce plants with a strong ability to fight mould and mushroom. They are suitable for indoor and outdoor growing with a very short and discreet structure. Highest samples don’t grow taller than 80 cm what makes them perfect for cannabis gardens with height and space restrictions. Speed Devil is also nominated as one of the marijuana strains mostly adapted to a polluted city environment which doesn’t seem to suppress her blooming and/or productiveness at all. In addition, they don’t have the same great nutritional requirements as some other strains, a weekly irrigation with a fertilizer is usually sufficient enough for their full development. While growing indoors, plants of Speed Devil can be left under 24 hrs light cycle or put under 18 one with no negative effect whatsoever. We would definitely recommend them for beginners.
Wherever you decide to grow this little devil, the result will be the same: plenty of resin and aromatic buds, mature and perfectly formed. This marijuana variety is a really good producer. Indoor yield is 300-450 gr per m2 while outdoor one is 15-50 gr per plant. Shiny crystals covering nearly a whole plant contain 15% of THC and 1.2% of CBD, a perfect combination for a strong cerebral effect.
