CannaArchive Light Schedule:
24/0 (LED, low intensity for seedlings)
Environment:
Temperature: ~22–24 °C
Humidity: initially high (around 70–85% RH), later reduced
Watering / Feeding:
Only very light watering was done during week 1 to keep the medium slightly moist. No nutrients were used. A small amount of CalMag was added after transplanting.
Observations:
All three seeds germinated successfully and entered the seedling stage. However, early development showed mixed results.
One seedling looks healthy and stable so far. One seedling is still questionable and shows weak development. The third seedling is declining and may not recover.
Issues observed include weak stems, slow growth, and yellowing cotyledons on some plants.
Reflection / Learning:
In hindsight, the combination of new coco tabs and high humidity for too long may have caused early stress.
Notes:
This week was mainly about observation and damage control. The focus moving forward will be on improving early seedling conditions and avoiding the same mistakes in future starts.

CannaArchive Environment:
Seedlings were kept in a warm and stable environment with gentle airflow. Light intensity was kept low to moderate to avoid stress during the early seedling stage.🌤️
Watering:
Watering was done very cautiously. The medium was only lightly moistened when needed, making sure it never stayed too wet. No nutrients were added during this week.💧
Observations:
Germination itself was successful, but Week 1 turned out to be more challenging than expected.
Out of three seedlings, two plants were lost during the seedling stage.❌🌱
They showed very weak early development, limited root growth, and instability shortly after emerging from the soil. Unfortunately, both seedlings collapsed and could not recover.
The remaining plant stayed alive and showed better stability, although overall growth is still slower than expected for this stage 🤞🌱.
Notes:
This week was mainly about observation and learning. It became clear how critical the very early seedling phase is.
The issues seem to be related to early root development rather than feeding or light stress. The germination process will be simplified in future runs to reduce stress and improve consistency going forward 💪🌿.
