Week 1 Summary - Grower Diaries: Auto Blue Dream in Aeroponic PC System
Initial Setup:
Seed: Auto Blue Dream (approximately 2.5 to 3 years old).
Germination Method: The seed was pre-soaked for 24 hours in water with a few drops of hydrogen peroxide to encourage opening. The seed was then transferred to a moist Rockwool cube for further germination.
Grow Box Environment: Set up with LED grow lights for a 20/4 light cycle (20 hours of light, 4 hours of darkness).
Environmental Conditions:
Temperature: Aimed for 22-25°C during light hours, keeping it no lower than 22°C at night.
Humidity: Target was set initially for 70-80% for optimal seedling growth.
Light: 20 hours per day to maximize vegetative growth.
Nutrition and Water:
pH Adjustment: Tap water was adjusted from 7.5 pH to 6 pH using pH Down solution.
Water Volume: 2 liters of water in the container.
Nutrients:
Sensi Grow A: 0.25 ml/l (total of 0.5 ml for 2 liters).
Sensi Grow B: 0.25 ml/l (total of 0.5 ml for 2 liters).
Voodoo Juice: 0.5 ml/l (total of 1 ml for 2 liters) to encourage root development.
Nutrient levels were kept at one-fourth the recommended dose due to the sensitivity of autoflower strains like Auto Blue Dream.
Issues Encountered:
Humidity Drop: One morning, humidity dropped significantly to 43%, likely due to the ventilation system balancing both temperature and humidity. This condition lasted for about 8 hours, leading to concerns over the health of the seedling.
Temperature Fluctuations: Challenges with maintaining a stable temperature range while controlling humidity.
Seed Shell Removal: The seedling initially struggled to shed its shell, prompting gentle manual assistance to avoid stunted growth.
Adjustments Made:
Fine-tuning the ventilation to stabilize both temperature and humidity for future stages.
Regular monitoring to ensure that pH and nutrient concentrations are stable.
Keeping a close eye on the seedling's development to identify any early-stage nutrient deficiencies or environmental stress.
This first week was focused on establishing a stable environment for germination and early growth, while navigating initial challenges typical to a controlled grow setup. The focus remains on keeping conditions optimal for the sensitive seedling stage, where any major fluctuations can impact early development.

Week 2 Summary
This week, the seedling showed slow growth and some challenges, like moldand specially with early leaf development. I kept the light cycle at 20 hours on and 4 hours off, maintaining steady light exposure while monitoring for signs of stress.
Nutrients & pH: I’ve kept the pH between 6.0-6.5, adjusted as needed, with PPM levels around 116–150. I added fresh nutrients this week to ensure balanced feeding without overloading the young plant.
Humidity & Temperature: The humidity was controlled between 60-70%, and the temperature ranged from 21-25°C. Balancing both has been a bit tricky since the exhaust fan reduces humidity when lowering the temperature, but adjustments were made as needed.
Issues Observed:
1. White spots and some orange residue were noted in the water reservoir, which I monitored closely. Some slight browning appeared on the seedling’s leaf, possibly from nutrient or light sensitivity.
2. A small root began to emerge, which is a positive sign of root development. The environment was kept clean, with pH adjustments and occasional peroxide use to prevent mold or algae.
3. The seedling still appears small for its age, so I’m carefully managing all conditions to support growth in the upcoming week.
Next Steps: I’ll continue with the 20/4 light cycle for now and monitor nutrient intake closely. Observing how the plant responds to these adjustments should provide more insight into its needs as it progresses.
Week 3 Review (Day 15 - Day 20)
This week was marked by significant efforts to stabilize environmental conditions and support plant growth. The plant has shown slow but steady development, and I made several key adjustments to maintain a healthy setup.
Key Nutrient Adjustments:
Nutrient Solution: Added 1 mL each of Sensi Grow A and B for a balanced nutrient mix.
Supplements: Included 2 mL of Voodoo Juice for root health and 2 mL of B-52 to strengthen the plant.
pH Management: Faced challenges with pH levels rising to 7.0 each evening, requiring daily pH down adjustments to bring it back to 6.0, which is crucial for nutrient absorption.
Environmental Conditions:
Lighting Schedule: Continued with 20 hours of light and 4 hours of darkness. Despite the plant's small size, high light exposure was maintained to encourage growth.
Humidity and Temperature: Humidity was regulated between 65% - 75%, and the temperature was kept stable between 21°C and 25°C.
PPM Levels: The nutrient concentration varied between 106 and 155 PPM throughout the week, indicating controlled but sufficient feeding.
Observations:
Plant Growth: The plant remains small but has shown some development. The leaves have experienced minor issues, likely due to earlier pH fluctuations.
Root Development: A visible root was noted, suggesting some progress in root health.
Concerns: Leaf health and slow growth remain concerns, but steps were taken to address these.
Steps Taken:
1. Adjusted pH down each evening to maintain a consistent level of 6.0.
2. Replaced and prepared a fresh nutrient solution while closely monitoring PPM levels.
3. Maintained stable humidity and temperature settings to minimize plant stress.
Goals for Next Week:
Continue to monitor pH daily and make adjustments as necessary.
Watch for signs of recovery and improved leaf health.
Ensure that environmental conditions remain stable, with no drastic fluctuations.
