420DeepGrow Thanks to the team at Doctor’s Choice, Xpert Nutrients, and Mars Hydro — without them, this wouldn't be possible.
🐍🖤 Black Mamba #42:
Feminized photoperiod genetic, a cross of Gorilla Glue #4 × Platinum Cookies F2 × DJ Short Blueberry. An American combination known for its potency, resin production, and spectacular dark pigmentation.
Compact and well-branched plant, with dense and very resinous buds. Its profile combines notes of blueberry, red fruits, and cookies, with a sweet and pronounced background.
📆 Week 0:
Started indoors. Germination on a paper towel with a good success rate, showing a uniform start and stable initial development.
The first days focused on promoting a strong root system and clean growth. Gentle watering with root stimulator, keeping the substrate aerated and slightly moist.
⚡ EC: 0.3
💧 pH: 6.2
🌡️ Water: 21°C
🌫️ Humidity: 70–80%
💡 Intensity: 200–250 PPFD
🔥 Cultivation note: Especially interesting genetic due to its black pigmentation and high resin production. It will be very interesting to see how it expresses its dark tones and its profile of blueberry, red fruits, and cookies.
We keep growing strong 💪!

420DeepGrow 📆 Week 3
This third week is marked by faster growth and a structure that starts to define itself more clearly. The new shoots are gaining strength, the leaves are increasing in size, and the plant is beginning to take up more space.
I raise the feeding to an EC of 0.9 to meet the higher nutritional demand, maintaining Master Grow and Master Root to support vegetative and root development.

🔥 Grow note: Third week completed with strong growth and an increasingly solid structure. The plant is responding well to the gradual increase in nutrition and continues to gain vigor.
We keep growing strong 💪!
