420DeepGrow Thanks to the team at Sweet Seeds, Xpert Nutrients, and Mars Hydro, without them this would not be possible.
🍈🌸 Pink Guava F1 Fast Version
F1 photodependent fast flowering genetics (Fast Version), created from elite lines with American genetics, characterized by its high homogeneity, hybrid vigor, and rapid transition to flowering. It presents a compact and productive structure, with very resinous and dense buds.
Very pronounced terpene profile, with tropical and fruity predominance, where notes of sweet guava, ripe fruit, and slight creamy nuances stand out. Ideal for indoor cultivation, where it expresses all its potential in optimized cycles.
📅 Week 0:
Start indoors. Germination on a paper towel is quick and uniform, showing from the very first moment the characteristic vigor of the F1. Clean emergence, with well-formed cotyledons and well-oriented first leaves.
Totally stable conditions from the start, ensuring an optimal environment for stress-free development. First gentle waterings with root stimulator, maintaining the balance between moisture and oxygenation in the substrate to favor a strong root from the start.
⚡ EC: 0.3
💧 pH: 6.2
🌡️ Water: 21°C
🌫️ Humidity: 70–80%
💡 Intensity: 100–200 PPFD
🔥 Cultivation note: The F1 Fast Version responds very quickly — a perfect start makes a difference in final production.

After several days of rain, the substrate became too wet, so watering is temporarily suspended and the top layer is removed to speed up drying. Fans are directed towards the pots to improve evaporation and oxygenation of the root zone.
Now indoors, they remain under moderate intensity while recovering pace without adding stress. New growth is noticeable and overall response is better, although still somewhat slow due to the excess accumulated moisture. The goal now is to reactivate roots and prepare for a strong entry into growth next week.

Week of reactivation after the substrate has completely dried. Watering resumes progressively, adjusting nutrition to support the restart of the root system without saturating the medium again. Good control of pot weight is maintained to ensure efficient watering cycles.
Silica Force is added, providing structural reinforcement and greater stress resistance during this transition phase. The plant responds with better turgor, more active shoots, and growth that is starting to pick up pace again after the forced pause.
Light intensity is slightly increased to accompany the rise in metabolic activity, maintaining environmental stability.

The fattening phase intensifies and the buds noticeably increase in size and density. The calyxes begin to stack up more quickly, the pistils remain mostly white, and the production of trichomes accelerates, increasingly covering the flowers and nearby leaves.
The demand for water and nutrients continues to be very high, while the plant concentrates almost all its energy on floral development. The aromas intensify and the gradual yellowing of the older leaves may become more evident without affecting overall vigor.

The buds continue to increase in density and begin to show their final shape. The calyxes are swelling more rapidly, resin production is reaching a very high level, and the aroma is becoming much more intense and complex. In many genetics, a slight reduction in the appearance of new pistils can be noticed.
The plant maintains a high consumption of water and nutrients, although vertical growth has completely finished. The progressive yellowing of the older leaves may become more evident as energy is directed towards fattening and maturing the flowers.

We reached the harvest with a Pink Guava that has produced a spectacular result. Compact, well-formed buds covered in resin, with an intense aroma and a very pronounced terpene profile.
Despite the difficulties of the last stage due to the evacuation, it managed to complete the cycle with an excellent floral structure and an incredible presence. Now it's time to enjoy the drying process and discover all its potential after curing.

The buds are reaching the end of the cycle fully formed, with great density, hardness, and a very high resin production. The pistils continue to darken and retract, while the aromas reach their maximum intensity and the terpene profile becomes increasingly defined.
The fade progresses naturally, and the plant concentrates its last resources on finishing maturing the flowers, completing the swelling and reaching the final harvest point.
This last week was marked by the evacuation, making it difficult to maintain the usual growing routine. Still, the plants managed to complete the cycle with a very satisfactory result.
