A sound grow room with a good climate is essential for a healthy harvest. Always allow a few days for a dry run, by this, turn everything on (except for the plants) and monitor if all the values are maintained within the specified values. (eg. temperature, humidity)

  • Provide sufficient exhaust air. min. 100m3 per m2
  • Ensure the room is 100% lightproof. Pay special attention to the ventilation openings
  • Don't place too many plants, approx. (20 - 25 per m2)
  • A good drainage systems saves time and money
  • An oscillating fan provides for good air circulation through the plants
  • 1x400W high pressure sodium lamp is sufficient to provide the optimum amount of light for 1m2
  • Good reflection in the form of mylar-foil, increases the output of the lamp.
  • Provide a large enough opening, or use a fan, for sufficient supply of fresh air.
