Sweet Seeds – Speed+ Auto Strain – Auto Fem


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. The Critical Mass was used for this project because of its speed to maturity as well as its yield and intense aromatic properties.

It will grow just about anywhere and its very short life-cycle means that even in the shortest outdoor growing season a successful harvest of marijuana buds will result. It is a short plant that will remain within the range 50 – 90 cm. Indoor yields will range between 350 – 500 gr/m2 while plants that are cultivated in an outdoor setting should produce between 30 – 150 gr. each depending on the usual external factors but especially the local weather conditions.

Speed+ Auto has a very complex and distinct aroma that incorporates sweet and fruity scents with notes of cheese and yeast. The effect is a very pleasant balance between a body stone and a head high.
