Mendo Guava Auto expands Fast Buds’ Champions Line by joining two high-performing autoflower lines in one experimental F1. It combines the exclusive Mendo Breath Auto IBL (GMO Auto x Mendo Auto) from Atlas Seed, the same parent used in Fast Buds’ Mendo Frost collaboration, with Guava Auto RF3, the refined version of a standout cup performer.
The plan pairs the efficient frame and deep terps of the Mendo Breath parent with the fruit, stability, and refinement that Guava RF3 brings. Fast Buds is aiming for dense flowers, serious resin production, and a profile that balances creamy sweetness with bright exotic fruit.
Plants reach 70-120 cm (28-47 in) in the XL size class, with a genetic split of 45% Sativa / 55% Indica. Under 18/6 or 20/4, with no light switch, they finish from seed in 8-10 weeks (about 56-70 days). Fast Buds lists 450-600 g/m² (1.5-2.2 oz/ft²) indoors and 60-220 g (2-7.8 oz) per plant outdoors.
This is an early release. The seeds have passed Fast Buds’ germination standards and the line is still being tested in-house, so it suits growers who want access to new collaboration genetics at the very start.
Creamy Guava Terps and Early Frost
Fast Buds’ first trials show plenty of hybrid vigor, a small-to-midsize frame, and resin piling up early in bloom. Bag appeal and smell both look strong across the plants tested so far.
The terpene profile layers sweet, creamy Mendo depth under fresh tropical guava and mixed fruit, with a spicy, fresh accent. It is a dessert-and-fruit combination that should carry well into concentrates.
Early grower reports lean surprisingly lively: creative and energetic come up most often, along with a giggly, good-humored mood. It suits daytime projects and social sessions more than sleepy nights.
Growing Mendo Guava Auto
Because it is a new F1, expect some variation between plants. A compact-to-medium frame fits most tents, and light LST helps even out the canopy. Give it the full 8-10 weeks and watch trichome color rather than the calendar before harvesting.
