๐ฑ Ghost Train Haze โ Week 5 From Seed (Late Veg / Pre-Transition)
This week nature reminded us whoโs in charge.
Outside temps dropped to 4โ5ยฐC with 90โ95% humidity, and instead of fighting it, we adapted โ and so did the girls.
๐ก๏ธ Environment
โข Tent temperature: ~21.8ยฐC
โข RH: ~58%
Considering the outside conditions, this is a very comfortable and stable environment, and the plants are showing zero stress signs. Leaf posture is relaxed, growth is steady, and overall vitality is excellent.
Weโre embracing seasonal changes rather than forcing extremes โ and the plants are responding beautifully.
โธป
Nutrition & Watering Strategy
Hand-Watered Plants
โข pH: 5.9
โข EC: 1.43
โข New addition this week: CalMag Pro โ 1 ml/L
This is not a reaction to deficiencies.
Calcium and magnesium become increasingly important during this phase due to:
โข accelerating cell division
โข structural development
โข increasing transpiration as light intensity rises
Introducing CalMag before problems appear helps maintain:
โข stronger cell walls
โข stable nutrient uptake
โข smoother transition toward flowering
This is prevention, not correction.
โธป
Autopot Zone
โข EC: 2.29
โข pH: 6.0
โข Solution temperature: ~22.8ยฐC
In the Autopots weโre running minerals only.
Organic inputs donโt behave consistently in passive systems and can lead to:
โข biofilm buildup
โข line blockages
โข unstable nutrient availability
Keeping this zone clean, mineral-based, and predictable ensures long-term stability.
โธป
๐ก Light & PPFD
โข PPFD range: ~700โ850 (depending on plant size)
โข Top light: 100%, unchanged
โข Plants are praying constantly and clearly growing toward the light โ no pushing, no forcing.
Under-Canopy & Inner-Canopy Lighting
โข Beginning of week: OFF
โข End of week: ON (very gently)
This is not to increase total PPFD yet.
The goal right now is education, not intensity.
By introducing photons:
โข from below
โข from inside the canopy
โข from multiple angles
โฆweโre teaching the plant early that light is everywhere, preparing structure and bud sites for later stages. Intensity will increase only as the plants evolve.
โธป
๐ฟ Training & Structure
โข No heavy training
โข No aggressive defoliation
โข Only:
โข leaf tucking
โข gentle branch bending
โข very light LST
These plants are naturally compact, with:
โข beautiful branching
โข large, healthy leaves
โข lush green color
โข excellent vigor in the Autopots
Growth is slower compared to other plants in the room, which may be linked to the sativa-leaning genetics. In my experience, sativas often:
โข develop more slowly early
โข take longer to finish
โข but reward patience later
Weโll let the plant tell the story.
โธป
๐ธ Veg or Flower?
This is a 12/12 from seed run.
Some plants in the room are already showing pre-flower.
Ghost Train Haze is not โ and thatโs completely fine.
She is still in vegetative growth, building structure.
Delayed transition can often mean:
โข more stretch later
โข potentially larger final size
But we donโt guess โ we observe.
The plant flips when sheโs ready, not when the calendar says so.
โธป
๐ Quick Recap for Newcomers
โข Week 5 from seed
โข Still vegetative
โข 12/12 light cycle
โข Stable environment despite harsh weather outside
โข Preventive CalMag introduced
โข Clean mineral strategy in Autopots
โข Multi-angle lighting slowly being introduced
โข Minimal intervention, maximum observation
โธป
๐ฎ What to Expect (and What Not To)
Expect:
โข continued structural development
โข slow, steady growth
โข eventual self-triggered transition
Do NOT expect:
โข forced flowering
โข rushed development
โข aggressive training
This run is about letting the plant express herself naturally.

๐ Thanks
Big thank you to everyone following along, supporting, and sharing knowledge.
Appreciation as always to the sponsors โ including Lumiflora for the under-canopy lighting โ and to the community that makes these shared journals meaningful.
Growers love
Onward, calmly and patiently.

Week 5 Veg/pre-flower | 8ร8 Tent | Master Conditions
๐ External Environment (Context) โข Outside temperature: ~5 ยฐC
โข Outside RH: 92โ96% (very high humidity)
โข Strong seasonal pressure influencing internal stability
โธป
๐ก๏ธ Internal Tent Conditions
โข Tent temperature: ~21.8 ยฐC
(noted drop due to cold external temps)
โข Tent RH: ~58%
โ Very good considering outside conditions
โธป
๐จ Airflow & Circulation
โข Primary airflow: Bottom โ top โ wall return
โข Pattern: Full-room vortex circulation
โข Additional fans: Central airflow to break blind spots and mix layers
โข Goal: No stagnant pockets, uniform VPD across canopy
โธป
๐ง Water Source & Rationale
โข Water: Dehumidifier water + rainwater
โข Base EC: force
โข Systems designed to support plant intelligence, not override it

๐ธ Photography Equipment & Tools
(Not sponsors, but part of my creative toolkit)
โข Sony A6700
โข Sony full-frame macro lens + few more
โข Stacking photography workflow - learning
โข iPhone (for behind-the-scenes shots)
Weโve got much more coming as we move through the grow cycles. Trust me, you wonโt want to miss the next steps, letโs push the boundaries of indoor horticulture together!
As always, this is shared for educational purposes, aiming to spread understanding and appreciation for this plant. Letโs celebrate it responsibly and continue to learn and grow together.
With true love comes happiness. Always believe in yourself, and always do things expecting nothing and with an open heart. Be a giver, and the universe will give back in ways you could never imagine.
๐ Growers love to all ๐
๐ธ P.S. โ The Eye Behind the Lens
All photos in this diary (for now โ except for the ones showing the camera, which I took with an iPhone) are taken with a Sony A6700 paired with a Sony full-frame macro lens and a few more.
Photography is part of the story โ itโs how we share the fine textures, the glow, and the quiet details that words canโt always capture.
Iโve also started experimenting with photo stacking โ a technique where multiple images, each taken at a slightly different focus point, are layered together to create one perfectly sharp image from front to back.
Itโs not digital enhancement or AI; itโs pure photography โ a way to reveal the plantโs beauty in microscopic depth, from trichome to petal.
Youโll even see a few shots of "ghost me" capturing the shots โ camera, lens, setup โ because every grow deserves not just to be cultivated, but documented like art.
