D33jW Summer grow just for the fun of it – testing new genetics and trying out a few crop steering techniques.
Germination went smoothly – the seed popped fast and healthy, which is a good sign right from the start.
Mandarin Zkittlez Lemon F1 is a hybrid that blends the fruity, sweet profile of Mandarin Zkittlez with the citrus punch of Lemon Skunk. Expecting rich aromas: mandarin, citrus, a hint of skunk, and possibly some colorful fade. Medium size, well-branched structure with juicy, resin-loaded buds.
Starting conditions:
🌞 Temp: 26°C
💦 RH: 80%
🌱 PPFD: 200–300 µmol/m²/s
🌬️ VPD: ~0.7 kPa
Low light and high humidity for now. Planning to play around with some techniques as the grow goes on.
Curious to see what this strain has to offer – feels promising so far!

D33jW Week 1 Update 🌱
Conditions:
🌞 Temp: 26°C
💦 RH: 80%
💥 PPFD: 200–300 µmol/m²/s
🌬️ VPD: ~0.7–0.8 kPa
🌱 Observations:
Watering with small amounts works very well – roots actively search for moisture and expand quickly without the risk of overwatering the medium.
It's important to observe the leaves to ensure they maintain a healthy structure: they should be firm and lying flat.
Leaf curling or twisting can be a sign of too much stress (such as excessive PPFD, incorrect VPD, or overwatering).
Let’s keep pushing 🙌

🌞 Temp: 27–28°C
💦 RH: 75–80%
💥 PPFD: 250–300 µmol/m²/s
🌬️ VPD: ~0.9–1.0 kPa
🌱 Observations:
The plants are growing evenly and vigorously, each already showing 4–5 developing side shoots.
It's a perfect moment to start planning upcoming training and selecting the main tops for SCROG.
Roots have begun to appear at the bottom of the pots — a great sign of a strong and active root system.
💧 Watering:
This week I increased the watering volume slightly.
One of the waterings included a bottom soak + light run-off.
The soil still has enough nutrients, so no additional feeding yet.
🛡️ Preventive Care:
Applied Clean Soil at 100–200 ml per plant as a preventive treatment against fungus gnats.
The plants responded very well — leaves are firm and slightly reaching upward.
🧠 Crop Steering TIP:
I’m still watering precisely and conservatively — only when the pots feel noticeably lighter.
This week I slightly raised the VPD (to 0.9–1.0) to encourage more vigorous, controlled growth.
Stay tuned – and keep growing 🌱

D33jW 📆 End of Week 1 FLO
This week was an important transition - the last one on organic nutrients.
➡️ I’ve been watering with plain water all week, and finished with Final Solution to flush the soil properly before switching to mineral nutrients.
I want to have full control over the feeding from now on - let’s see how the plants respond.
🌱 I'm really happy with the veg phase, good watering practices and airflow management paid off.
The plants are healthy, strong, with thick and solid stems - exactly what I was aiming for 💪
Now it's time for the bloom to shine 😎
