Speed + Auto is aptly named as it takes an incredible 7 weeks from germination right through to harvest. This must be the single fastest automatic cannabis strain available anywhere. Speed+ Auto was created by crossing an auto-flowering Critical Mass from Sweet Seeds' own research & development team with its own Speed Devil #2 Auto.

Big Devil Auto grows quite tall for an auto-flowering strain reaching a height of between 1 meter - 1.5 meters. It produces a good yield of dense, compact and highly resinous buds with the aroma of incense and a fruity flavour that also includes some Skunk overtones.
