Arugula recipe

Peter K. says this is an easier, hearty plant to grow for testing the PFC.

Germination

Description

  • Seed: Go to Johnny’s Seeds online and order a packet of plain old, regular arugula.
    • Regular arugula germinates from seed in 5-7 days and is fully mature in 40 days.
    • This is yummy: wasabi arugula (5-7 days germination, 45 days to maturity).
  • Temperature:
    • Arugula does not require as much warmth as basil. Eventually, we’ll tweak night temp down to maximize quality but for now let’s go with maximum growth as we learn how to grow in the PFC.
    • Day: 21.1°C == 70°F
    • Night: 15.6°C == 60°F
  • Humidity: 60 (40 ~ 70% RH)
  • Photo-period: 16 hours
  • PAR: 300
    • Arugula is still in the leafy greens category, if my 300 umole recommendation has resulted in the tight basil response you could try the 250.
    • Spectrum: basic 80/20 red/blue, can work in some white if you want to provide some other wavelengths
  • pH: 6. range is 5.4 - 6.2
  • Nutrients: 150 ppm nitrogen from our A/B combo, arugula could go a bit higher at 200 ppm nitrogen.
    • Later we can dial in. Sometimes nutrition can be iffy if other growth factors are off and starting out a bit lighter is better than too strong while other growth parameters are being dialed in.
  • EC: Dose consistently per instructions from bottle
  • CO2: Ambient OK / 1,200 ~ 1,500 with doping
