420DeepGrow Thanks to the team at Anesia Seeds, Xpert Nutrients, and Mars Hydro, without them this would not be possible.
🍉❄️ Iced Melon Watermelon (Anesia Seeds):
Photodependent genetics with an explosive terpene profile, highlighting sweet and refreshing aromas of watermelon and melon with a slightly acidic background. It shows vigorous growth with a balanced structure between indica and sativa, good lateral branching, and high resin production. Ideal for indoor cultivation where it can express all its aromatic and productive potential.
📆 Week 0:
Start indoors. Germination on a paper towel with a good success rate, showing rapid and uniform emergence. From the very first moment, hybrid vigor is noticeable, with seedlings that open cotyledons forcefully.
First gentle waterings with root stimulator, keeping the substrate slightly moist but not saturated, favoring oxygenation and initial root development.

After being outside, one of the plants was damaged by the dog and only one remains in cultivation. After the rain, the substrate became too wet, so watering is suspended until proper drying is achieved. Now indoors, it is kept under moderate intensity to promote recovery without adding more stress.
New growth is noticeable and there is a gradual improvement in vigor, although still somewhat slow due to the excess accumulated moisture. The goal now is to reactivate the roots, dry the medium well, and prepare for a strong entry into growth during the next week.

The stretch reaches one of its most intense points, and the plants show outstanding development, gaining height and volume consistently throughout the week. The structure has opened up evenly, allowing the secondary branches to reach levels similar to the main tips and forming a well-distributed and efficient canopy.
The flowering sites begin to multiply all over the plant, and the first clusters of pistils become clearly visible. The high growth rate is accompanied by a notable increase in water and nutrient consumption, reflecting an active root system and excellent absorption capacity. The plants maintain a vigorous and healthy appearance, responding very well to the growing conditions.

📆 Week 5
The stretch has finished and all the plant's energy is directed towards fattening the flowers. The buds are getting bigger day by day, starting to cluster along the branches, and the resin production is becoming more and more evident. The canopy remains uniform, allowing for optimal light utilization.
Water and nutrient consumption has reached one of its highest points in the grow. The plants are absorbing practically all the available fertilization, showing consistent floral growth, healthy leaves, and a very active metabolism.
