Guava Auto RF3 by Fast Buds

RF3 is the label Fast Buds uses to mark its most refined versions, and Guava Auto RF3 is the one that has gone to its tropical autoflowering strain. Eight generations of selection later, the plant arrives more uniform, with tighter structure and a resin load designed for anyone who, in addition to flower, wants to extract.

What changes in the RF3 version

Against the Guava Auto as always, the RF3 raises the power ceiling from 28 % to 30 % THC and expands production: from 450–550 g/m² it goes to 450–600 g/m² indoors, and outdoors the range stretches from 60–200 to 60–300 g per plant.

The rest of the parameters remain the same, and that is also useful information: it is still an 8–9 week auto, 70 to 120 cm and with a 50/50 split between indica and sativa. What changes is not the calendar, but the uniformity between plants, the tightness of the bud and the number of trichomes.

Growing Guava Auto RF3

The bank presents it as a straightforward variety: it does not ask for complex training or an aggressive feeding schedule to set hard buds. It resists pests, mould and environmental stress well, so it performs indoors, outdoors, greenhouse and mixlight.

At 70–120 cm it fits in modest grow tents, and its XXL classification comes from the yield, not the height: the volume comes from bud density. That's why it fits squarely among XXL Autoflowering Seeds.

Terpenes and effect

The profile is ripe guava taken into sweet territory, with creamy layers and a fruity undertone that becomes noticeable in the room quite before harvest. It's the same aromatic family as Guava Auto, but with a more pronounced terpene after selection.

The effect Fast Buds describes matches that profile: a bright and creative start, sociable, that gradually moves towards a soft bodily relaxation without dimming the afternoon.
