Speed of outgoing TD SilentDo you adjust the ventilator speed over time? I have a TD Silent with 5 possible speeds and keep the lowest speed at night (so I can sleep) and on 3 or 4 during day to be sure. Is there a trick to find the best yet lowest speed?Setup. Ventilation

couple quick questionsDo I need to close the flap to the vent during dark cycles? (Lights off during the day) and should I block lights coming from fan power, humidifier, dehumidifier, or indicator lights?
Also do I need to use the carbon filter the whole time?

Thank you!

Auf der Suche nach der richtigen Luft EinstellungEquipement
- Growtent 100*100*200= 2m³
- 2 Vents ca. 280m³/h (1 Zuluft, 1 Abluft)
- 1 Cli-mate mini Humi 300W
- Filter 125-400M³/H
Die Panzen brauchen ca. 140 m³/h frische Luft und so müssen die Vets immer auf 50 - 60% in Betrieb sein richtig? Oder kann ich auch tiefer gehen?Week 1

Peltier dehumidifier @300ml per day adequate for 3x3x6 tent? Alternatively, a conventional dehumidifier outside the tent?Peltier thermoelectric dehumidifiers extract 300ml of water per day. Weak compared to compresser units, small and use less energy. Is it enough?
Would a conventional dehumidifier set outside of the tent near the intake be effective, or does it need to be inside the tent to work2y ago
