A good grow log makes next grow better. A bad one is just a graveyard of forgotten photos. Focus on the data you'll actually compare across runs.

  • Strain + breeder + pack date
  • Sow / transplant / flip / harvest dates
  • Feed: brand, recipe, EC, pH (per feeding, not per week)
  • Environment: peak day temp, low night temp, day RH, night RH
  • Pot size + medium
  • Light schedule + PPFD reading once per stage
  • Notable events: pest sighting, deficiency, training
  • Final weight + sample notes
