Critical Mass (automatic)Speed Devil #2 Auto®
Quite possibly the fastest auto around.

This hybrid is the result of crossing an auto-flowering Critical Mass genetic line from the Sweet Seeds®´ R&D Department, chosen for its fast flowering and pleasant intense aroma, with a selected strain of very fast flowering, our Speed Devil #2 Auto®.

This auto-flowering variety has been developed through the search for the genetic traits responsible for very fast flowering. The final result is a strain that is ready to harvest only 7 weeks after germination. It produces thick buds covered with aromatic resin. Sweet and fruity aromas with hints of yeast and cheese.

Customer Service
Customers report that seeds germinate and grow at varying speeds, with some plants developing quickly while others show inconsistent growth patterns and occasional issues like nutrient sensitivity. Most growers find that the advertised 7-week harvest time is optimistic, typically requiring 8 to 11 weeks for seeds to fully mature and develop properly. Despite the longer-than-expected timeline, many customers appreciate the final results, including potent flavor and strong yields, making the extended germination and growth period worthwhile for patient growers.

Speed + Auto Feminised Seeds - 5
Grows extremely slow and barley got over 8 inches tall. Out of the 10 I germinated, 3 were duds and the rest were very small and one even topped itself two weeks after sprouting.

Speed + Auto Feminised Seeds - 3
Their were actually 4 seeds. Of the four seeds none of them popped. I soaked the seeds for over 72 hours with no signs that they might begin to start to show a taproot. They were then placed in the wet paper towel method for germination, but after 6 days there was no signs of germination. The seeds were subsequently planted in a growing medium of soil and never showed any signs of germination or growth. The seeds upon initial examination looked very small and in mature.

This is a tough one. Out of 5 I ran, 2 were absolute weirdos. Both weirdos had bizarre deficiencies visible immediately from popping above soil. They also had extreme sensitivity to nutrients as they aged, it was constant work to finesse them through to harvest. They had wild growth spurts and ended up being over 4ft tall. They both also tried to go hermie near the end of flower. They were grown under the same conditions, with the same everything as the rest as well as plenty of other plants in the past and since, so I tend to think it wasn't me stressing them out. They were just misfits lol. The other three were fast, compact, good yielders that grew as advertised. Very healthy and robust. Here's the thing with this strain. The smoke is awesome. Seriously it's strong as hell and tastes ridiculously good. The buds are dense and pretty, with a smell after curing that's like some kind of baked good with cinnamon and fresh linen. It presses huge yields of high quality rosin as well. That's why my score is so high for this strain. You run the risk of wonky phenos, but Sweet Seeds do give you an extra 2 seeds with your 5 pack and the smoke is so good even from the weirdos that it's worth growing.

Speed + Auto Feminised Seeds
The plant might have been done most of its growing at 7 weeks, but it's buds were certainly not ready yet. At 7 weeks the trichomes were still clear and few if any of the pistils had turned color. I kept her going almost as long as the other two plants in the tent, which were done at about 12 weeks, so I'd say about 11 weeks for the Speed+ Auto. Letting it go longer, however, resulted in fat frosty buds (then again everything during that grow had huge frosty buds. changed the way I feed and added supplemental light including UVB.
