Speed Devil #2 Auto feminized seeds



A Quick, Indica-dominant Autoflower

Speed Devil #2 Auto is an autoflowering cannabis strain developed by Sweet Seeds. This 3rd generation autoflower is the next in the evolution of Speed Devil Auto - a very quick, Indica-dominant autoflower with excellent yields - and offers all the benefits of the parent but from a plant than can grow much bigger.

This version of Speed Devil Auto has everything the parent is loved for - heavy yields of potent, resinous cannabis in as few as 8 weeks from germination - but with improved yields, increased size and trichome coverage. Indoor yields for this strain are 400 - 500 gm2 while outdoor growers can expect to pull between 20 and 60 g per plant. For this reason, it’s recommended this strain is grown indoors with some additional training to maximise yields. Here is some further information on how to make the most out of this grow:

  • Medium plant – due to her Indica-dominant genetic lineage, this strain reaches a final height of 80 cm;
  • Max EC of water – 1.4 in veg, up to 1.6 during flower;
  • Water pH; 5.8 – 6.0;
  • Recommended lighting: 600 W HPS;
  • Recommended nutrients: General Hydroponics Flora Trio.

Speed Devil #2 Auto: Bigger Buds!

Speed Devil #2 Auto has a smell, taste and appearance which is almost identical to that of her parent Speed Devil Auto but differs in the fact that Speed Devil #2 Auto is slightly larger and forms larger buds. Both strains have a pungent aroma and relaxing head high which stimulates for hours on end.
