420DeepGrow Thanks to the Terpyz team, Xpert Nutrients, and Mars Hydro, without them this would not be possible.
🖊️🌿 Lemon Parmesan (TerpyZ):
Very modern and peculiar genetics, focused on intense and unconventional terpene profiles 🍋🧀
Combines citrus notes like acidic lemon with a creamy, funky, and slightly "cheesy" background, creating a complex, powerful, and very characteristic aroma.
Normally compact structure, with good resin production and an aromatic expression that evolves a lot during flowering 🌿
Variety oriented towards flavor, uniqueness, and striking terpene profiles within TerpyZ's more experimental line ✨
📆 Week 0:
Start indoors with germination on a paper towel and direct transfer to the final pot to avoid root stress.
The seedling emerges vigorously, showing stable growth from the start.
A controlled environment is maintained with high humidity and soft light to favor rooting and early adaptation 🌱
Light watering around the stem with root stimulator to boost initial development.
⚡ EC: 0.3
💧 pH: 6.2
🌡️ Water: 18–20°C
🌫️ Humidity: 65–75%
💡 Light: PPFD 150–250
🔥 Note: In complex profile genetics like this, a stable base from the start is key to expressing its citrus-creamy mix well during flowering.
We continue to grow strong 💪!

The Lemon Parmesan enters its first week of vegetative development 🌱
The plant shows stable growth, with good formation of new leaves and a compact structure that is starting to clearly define itself.
The internodes remain short, with a balanced development between roots and aerial parts, a sign of good adaptation to the indoor environment 💡
A healthy and uniform color is noticeable, without deficiencies or excesses, maintaining a constant growth rate.
The root system continues to expand under controlled conditions, consolidating the base for the next phases of growth.
Humidity and gentle light remain key to avoiding stress and promoting a clean transition in this initial stage 🌿

The plants are finishing the vegetative phase, showing a strong, balanced, and well-branched structure.
The recovery after the apical pruning has been complete, resulting in multiple main tops distributed evenly throughout the canopy. The height is kept under control, and the productive surface has expanded considerably, allowing for better utilization of the available lighting.
With the switch to 12/12, the transition to flowering officially begins. Over the next few days, the plants will increase their metabolic activity and prepare the structure that will support future floral production.

The transition to flowering is progressing strongly, and the plants are responding excellently to the new photoperiod. The stretch is becoming evident, with consistent vertical growth that allows the different tops to reach a more uniform height.
The first pre-flowers are developing at all the upper nodes, and the secondary branches are gaining prominence, occupying the available space in a balanced way. The structure achieved during growth facilitates good light penetration and prepares the plant for an abundant flowering.

The stretch enters its most intense phase, and the plants show very rapid growth, gaining height and volume consistently. The secondary branches reach the main tips, forming an increasingly uniform canopy ready to receive even lighting.
The flowering sites begin to multiply all over the plant, and the first buds take shape at the tips, while the root system easily supports the increased demand for water and nutrients. The structure is practically defined to face the upcoming weeks of fattening.

The stretch is entering its final phase, and the plants continue to grow very vigorously. One of the two shows a clear sativa dominance, with very vigorous growth and greater internodal spacing, requiring height control to maintain a balanced canopy.
The buds are starting to gain volume at all the tips, and resin production is increasing, while the plant begins to gradually redirect its energy from vertical growth to floral development.

The stretch is entering its final phase, although one of the phenotypes is maintaining very vigorous growth and is close to reaching the ceiling of the closet (1.40 m). If it continues at this pace, I will have to move it to a taller space or take it outside, where it will probably need support due to its thinner branches.
The buds keep gaining volume and the resin production increases every day. I keep the EC stable, as the plants are responding perfectly and starting to focus their energy on flower development.

The stretch is coming to an end, and the plants are definitely focusing their energy on flower development. The buds are starting to compact quickly, the calyxes are stacking up, and resin production is noticeably increasing. The most vigorous phenotype has been moved to the taller cabinet so it can complete its development without limitations, while the rest maintain a uniform structure ready to face the maximum fattening phase.

The buds continue to advance strongly in their final fattening phase, progressively increasing their density, hardness, and weight. The resin production remains very high, and the flowers show an increasingly compact and mature structure. The pistils are gradually starting to darken and retract.
The aroma is becoming especially intense, with a citrus and fresh profile accompanied by marked notes of fuel, making the terpene character of this genetic stand out more and more.
