Week 7 Flower – Roller Coaster Haze (Zamnesia Seeds)
The Final Push Begins
Here we are, Week 7 of flower, and the Roller Coaster Haze girls are standing tall, magnificent, and absolutely covered in white hairs and swelling calyxes. These monster plants have truly lived up to their name, a wild ride from germination until now, and this week marks an important turning point in their journey.
This week they received their last feed with nutrients, watered at pH 6.0 and EC 1.42. From here on out, it’s pure water only. The soil still carries enough reserves to sustain them as they finish ripening, and I want them to cleanly express their genetics all the way to harvest.

Environment Control – Heat vs Balance
Outside, the temperatures are brutal — reaching 45°C (113°F) — but thanks to the combined ecosystem of TrolMaster and Spider Farmer controllers, the room remains stable:
• Room Temp: ~28–29°C
• Humidity: ~65%
• VPD: ~1.3–1.4
Even under pressure, the system holds strong, giving the plants exactly what they need to thrive in these final weeks.

Lighting Adjustments – Simulating the End of the Season
Light is one of the most powerful tools we have, and this week we began shifting the spectrum to signal “end of season” to the plants:
• Whites & Blues: slowly being reduced
• Reds: increased to 100%
• Far-Red & Deep Red: 100%
• UV: 100%
This spectrum mix encourages ripening, resin stacking, and terpene expression while mimicking the natural transition of sunlight as summer ends. The plants respond by pushing their energy into the flowers rather than continuing vegetative growth.

Plant Development – Giants in Full Force
The girls are absolutely towering now, monster plants with stacked colas and pistils shooting out everywhere. Their root systems are so strong that some roots at the soil surface are even thicker than the stalks themselves.
By the end of this week, Pheno #3 was harvested, though I will dive into the full harvest details later. Pheno #2 remains in full bloom, swelling, and shining bright.

What to Expect vs What Not to Expect
Expect:
• Continued swelling of buds and trichome development
• Pistils slowly beginning to darken and curl in
• Leaves showing natural fading as stored nutrients are consumed
• Stronger aromas and denser resin production
Not to Expect:
• Any more vegetative growth or stretching
• Heavy feedings, the focus now is ripening, not building

Final Thoughts
This week feels like the beginning of the final push. With nutrients removed and the spectrum shifted, the Roller Coaster Haze is entering her true finishing phase. These plants have been a wild, beautiful ride, and it’s only a matter of time now before the final chapters are written.
As always, thank you all for following along, sharing your knowledge, and riding this wave with me. The support means everything, and I can’t wait to share the harvest details soon.
Let’s grow together,
