If anyone is interested in my more Scientific log
Growth Stages and Time Frame:
Seedling: 1-2 weeks.
Vegetative: 4-8 weeks.
Flowering: 8-12 weeks (depending on strain).
Environmental Stats:
Temperature:
Day: 68°F-77°F (20°C-25°C).
Night: 62°F-72°F (17°C-22°C).
Humidity:
Seedling: 65%-70%.
Vegetative: 40%-70%.
Flowering: 40%-50%.
CO2 Levels: Keep between 1200-1500 ppm during the vegetative and early flowering stages if you're adding CO2.
Nutrient Levels:
EC (Electrical Conductivity):
Seedling: 0.8-1.2 mS/cm.
Vegetative: 1.2-1.6 mS/cm.
Flowering: 1.6-2.0 mS/cm.
pH Levels:
Soil: 6.0-7.0.
Hydroponics: 5.5-6.5.
Watering Stats:
Water Quantity: Based on plant size (e.g., 500ml for young plants, increasing to a liter or more for larger ones).
Water pH: Keep between 6.0-7.0.
Frequency: Varies by growth stage (every 2-3 days typically).
Light Intensity:
PPFD (Photosynthetic Photon Flux Density):
Vegetative stage: 400-600 µmol/m²/s.
Flowering stage: 600-900 µmol/m²/s.
Plant Height and Canopy Spread:
Record changes weekly as part of plant growth data. This will help monitor stretch during flowering and overall health.
Observation Log:
Any signs of stress (leaf yellowing, curling, spots).
Pests or mold occurrences.
Training techniques used (topping, LST, etc.).
Flowering stage observations (pistils, trichomes development).
