420DeepGrow Thanks to the team at Sweet Seeds, Xpert Nutrients, and Mars Hydro — without them this wouldn't be possible.
🌿⛽ Jack 47:
Feminized photoperiod genetic from Sweet Seeds. A variety that stands out for its vigor, structure, and a very interesting resin production, combining power and final quality.
A well-developed plant, with a balanced structure and a flowering that promises excellent production. Its aromatic profile mixes sweet and spicy notes with an intense, earthy background, accompanied by that powerful character that defines this genetic.
📆 Week 0:
Starting indoors. Germination 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 Master Root, 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: A classic genetic from Sweet Seeds that I was eager to grow again. It will be interesting to follow its evolution and see how it develops its structure, resin production, and aromatic profile throughout the cycle.
We keep growing strong 💪!

420DeepGrow 📆 Week 1:
This first week has been a bit more complicated than expected. The root has suffered a bit, and this is making it hard for the plant to get going and develop the aerial part at the usual pace.
I’m keeping Master Root at low doses to encourage root recovery and starting with Master Grow gently, aiming to provide what’s necessary without forcing development while it finishes recovering.
⚡ EC: 0.4
💧 pH: 6.2
🌡️ Water: 21°C
🌫️ Humidity: 70–75%
💡 Intensity: 250–300 PPFD
🔥 Grow note: A somewhat slow start for this Jack 47, but the root remains the priority. It’s time to give it space to recover and start picking up pace.
Let’s keep growing strong 💪!

420DeepGrow 📆 Week 2:
In this second week, the Jack 47 is starting to show positive evolution. The root continues to recover and, little by little, the plant begins to pick up pace, developing new leaves and strengthening its structure.
I keep Master Root at low doses to continue supporting root development and I continue with Master Grow gently, maintaining a contained EC so as not to stress the plant while it finishes recovering.
⚡ EC: 0.4
💧 pH: 6.2
🌡️ Water: 21°C
🌫️ Humidity: 65–70%
💡 Intensity: 300–350 PPFD
🔥 Grow note: The Jack 47 is starting to react after a somewhat complicated start. Recovery is on the right track, although we still need to proceed calmly and maintain gentle feeding so that the root continues to strengthen.
We keep growing strong 💪!

420DeepGrow 📆 Week 3:
In this third week, a positive change in the growth rate is noticeable. The plant is starting to gain more strength, developing new leaves and a progressively more defined structure, while the root system continues to recover.
I increased the feeding to an EC of 0.9 to meet the higher demand, maintaining Master Root and Master Grow to support both root development and vegetative growth.
⚡ EC: 0.9
💧 pH: 6.2
🌡️ Water: 21°C
🌫️ Humidity: 60–65%
💡 Intensity: 400–500 PPFD
🔥 Grow note: Recovery continues to progress, and the gradual increase in nutrition allows the plant to start regaining a stronger growth rate.
We keep growing strong 💪!
