Hi everyone and welcome! This is my first grow. As a scientist I like to focus on the small details for optimization. Any information is always welcome! Spread the knowledge!
I would like to thank everyone who has posted here over the years and kept journals.
I'm a long time reader, first time poster and grower, and have learned an incredible amount from you all.
Let's get going on the details of the grow.
- Strain -
Strain: Vanilla Frosting
Type: Hybrid
Percentages: 65% Indica 35% Sativa
Source: Female Clones from THC Design after first visible root.
Veg Stage: 3 Weeks (6/2 Lighting Schedule)
Flowering Stage: Flipped to 12/12 two days ago.
Topped: Middle Week 2, LST Week 2 until now, re-positioning every two days.
Defoliation: Every few days, so many fan leaves its insane.
- Medium and Nutrients -
Medium: FFOF (Fox Farm Ocean Forrest) Soil 70%, Perlite 29%, 1% Mosquito Bits (Bacillus Thuringiensis subspecies: Israelensis). The reasoning for the Mosquito Bits is preventative maintenance against any fungal gnats which feast on roots. I had this destroy some vegetables I was growing inside and this solved my problem years back. I use this in the mix and sprinkle a teaspoon worth on the top once planted. I never see fungal gnats in any of the indoor plants, so it seems to work well.
Nutrients:
Fox Farm Trio - Grow Big, Big Bloom, Tiger Bloom
Fox Farm - Wholly Mackerel
Fox Farm - Kelp Me Kelp You
Fox Farm - Microbe Brew
Fox Farm - Flowers Kiss
Fox Farm - Sledge Hammer
Botanicare - Sweet (Raw)
Mad Farmer - Get Down
Mad Farmer - Mother of all Blooms (M.O.A.B)
Rhizoflora - Terpinator
Home Made - Neem Oil/Citrus Soap Mix
- Hardware -
Grow Space: Attic Crawl Space, 3.2' x 2.5' x 5.5' Lined with Reynolds Aluminum Foil, 2 Rolls
Air Flow: 12" Intake fan connected to humidifier shoots cool air up into the crawl space, two 6" Post fans oscillate around the base of the plants, one oscillates over the top. 12" Exhaust fan sits above crawl space entrance near intake fan. Provides constant air flow around the entire crawl space.
CO2: MyCO2 Bloom Blue Oyster Mushrooms x 3, total ppm 1200
Humidifier: Vick's Cool Moisture Humidifier.
Heater: 125W heat lamp enclosed in a black box, used during lights off hours.
Grow Light (Clone Week): LED/T5/CFL
Grow Light (Week 2): 180W Full Spectrum 12" above, 100W LED, enhanced red/blue, combined around the sides illuminating the lower canopy/any hidden leaves, 6 - 10" away.
Grow Light (Week 3-Flowering): 315W Phillips 3100k CMH in Mantis Horticulture Ballast/Reflector 18" above canopy, 100W LED, enhanced red/blue combined around the sides illuminating the lower canopy/any hidden leaves, 6 - 10" away.
Light Cooling: None except for circulating air.
Plant Pots: 3 Gallon Black Plastic, with ~ 100 small 4mm drilled holes for added root ventilation.
Mounting: Zip-ties, Hooks in the roof. Allows for constant 1" adjustments at basically no cost.
- Tools -
Spectrometer: Ocean Optics HR2000+ (Measure spectral intensity distribution above the canopy and below for optimization of PPFD/PAR)
Thermal Camera: Seek Pro (Measure Leaf Temperature)
Humitity/Temp: ThermPro TP60 x 3
Trimmers: Kiku 8" Bonsai Scissors
pH/EC/TDS Meter: Vivosun Amazon
Microscope: Vividia V1-PS 2MP Handheld USB
Reservoir: Gravity Feeding hung from ceiling
Light sensor: Lux Sensor Edmund
- Environment -
Lights ON Temp: 77-80F
Lights OFF Temp: 71-73F
RH Veg: 58-61%
RH Flower: 46-48%
pH: 6.5
Veg ppm: 750-850
Veg EC: 1.7
Flower ppm: 950-1100
Flower EC: 2.1
Leaf Temp: 75-78F, Room Temp - 2 (Measured with Thermal Imaging Camera)
Calculated VPD Veg: 0.97-1.04
Calculated VPD Flower: 1.4 - 1.5
Calculated PPFD from Spectral Intensity Distribution/Lux Measurement: 545 umol/m2/s
- Feeding Schedule -
Dryness: Knuckle Method (~2-3x/week veg and ~3x/ week flower)
Quantity: Half Gallon / Plant (results in 5% runoff)
Nutrient Feeding: Half Strength of Fox Farm Feeding Schedule, every other watering, (pH to 6.5 each time with Terpinator every watering)
Foliar Spray: Once a week for 3 more weeks.
Flush: Every two week.
I'll be adding some photos of the ladies soon. Feel free to ask me anything or point out any info I forgot to mention.
