+ Speed Auto: Give Your Grow a Boost!

Speed Auto is an autoflowering cannabis strain developed by Sweet Seeds as a cross between an autoflowering Critical Mass – a fast flowering well-balanced hybrid – and Speed Devil #2 Auto (SWS25), in pursuit of creating the ultimate, rapid flowering autoflower which delivers pungent high quality cannabis.

If you want heavy yields of dense, resinous, slightly Sativa-leaning cannabis in lightning fast times, you will be more than satisfied with Speed Auto. In addition to a THC content of up to 20%, she contains an average 0.7% CBD. This versatile strain is suitable for both indoor and outdoor cultivation with indoor yields between 350-500g/m2 and outdoor yields of 30-150g/plant in a total grow time of 7 weeks from germination. Here is some further information on growing this strain:

  • Max EC of water – 1.0 in veg, up to 1.4 in flower.

Excellent Bud-to-Leaf Ratio
