Description
Auto Mass by Grass-o-Matic is one of this bank’s sweetest strains. If you liked Critical mass with its potent, sweet flavors, then you’ll love this strain that takes just 65 days to fully mature. This plant can be grown both indoors and outdoors, although it does much better indoors.
Indoors if you want to do a SoG system which you normally use on mother plants and clones, you should place 9-12 plants per square meter. Auto Mass centers most of its yield along its central stem, so if you grow it this way you’ll be able to increase yield quite a lot. After 60-65 days it should be fully mature and ready to harvest, yielding up to 500g.
Outdoors it grows into a more open structure, with its branches opening up to allow sunlight to reach the entire plant – they’ll grow shorter but wider. You’ll also be able to harvest various times per year, especially if you live in warmer areas. Even though it’s a Critical strain, it’s still resistant to fungi.
It has a strong, fruity flavor that’s perfect for habitual smokers that like dense smoke and fast yields. It gives a relaxing and socially active effect that can have you couch-locked and worse if you toke too much.

I really liked this auto, even outdoors. I had read that it was sensitive to fungus, but it handled the humidity just fine. The size is impressive for an auto, it grew really sturdy. How many times can you plant per cycle? I'm already thinking about the next batch.

Gostei muito dessa auto, mesmo no exterior. Tinha lido que era sensível a fungos, mas aguentou a umidade numa boa. O porte é impressionante para uma automática, ficou bem robusta. Quantas vezes será que dá para plantar por ciclo? Já estou pensando na próxima fornada.

This strain is amazing for SCROG, huh? Very dense buds and generous yield. Only thing, a bit too leafy for my taste, but oh well, trim it and that's it. Definitely doing it again.

Esta genética es una maravilla para SCROG, eh? Cogollos bien densos y producción generosa. Lo único, un poco hoja para mi gusto, pero bueno, se limpia y listo. Repito fijo.
