The custom built microgrow cabinet is in tip top shape.
Cabinet parameters:
Area: 70x35 cm (1.15x2.3 [ft]) = 0.25 m² (equivalent to 2.6 ft²)
Volume: 70x35x70 cm (1.15x2.3x2.3 ft) = 0.09m³ (equivalent to 3 ft³)
Lighting range: 10-100 W
Extraction range: 70-270 m³/h (equivalent to 41-159 ft³/min)
Very satisfied with ambient control so far.
Grow parameters:
PPFD: 170-180 µmol/m²/s
DLI: 12 mol/m²/d
Substrate: 1.2 mS/cm - pH 6.2
Water: 1/2 Tap + 1/2 R.O. = 0.75 mS/cm - pH 7
Temperature range: 22-25 °C (equivalent to 72-77 °F)
RH range: 70-80 %
Probably will need to use the bigger DIY ultrasonic humidifier during the vegetative stage, when PPFD increase and summer heat will rise temperatures.
The only seed that was planted successfully sprouted.
All is well. Take a seat and enjoy the ride 😊
