Humidity control in growtent
Lazulistarted grow question 3y ago
Heres a short vid of the setup please let me know your way of doing things, is this ok or is there a better way ? The fan sucking air out = 45watts in a 4x4 tent. Dehumidifier 300watt, would a smaller dehumidifier like 150-200 watt also put humidity under 50% ?

My 200w dehumidifier puts is as low as 45%. And I keep it outside tent, next to passive air intake.

The humidity in tent is what matters. If a smaller dehumidifier keeps level down then yes. Keep humidity below 65 percent in vegging, low as possible when you have flowers to avoid any rot. So you might be able to turn it down in vegging and only have to run it strong in heavy flowering. It is up to how your humidity is in tent overall.

Using humidistat to control fan, will this cause problems? So far fan running for 30 secs every two minutes! Plz advise if this is not a good idea??My exhaust fan is to powerful no speed control just two settings. On the lowest setting the fan is still sucking all the humidity that my humidifier creates out of the tent. So I have bought a humidity controller hooked it up with the humidifier and fan.. It’s working great!!Setup. Ventilation

Temps Humidty Optimization, Worried about mid/late flowerHello guys
My grow tents have high humidity. A fan is venting into attic.
There is a vacuum in the room so the air is circulating+ dehumidifer outside tent
Maybe too many plants?
Night~19°
Day~25°
55-62%
RH too high for flower?
Want to prevent budrot. Temps OK?
Any ideas?
Thanks!

Silent inline fan recommendation (Europe)Hello growers, I am looking for a somewhat silent fan for my 2x2. AC Cloudline is not readily available in my area.
I'd love some feedback on those : RAM Silent 125mm, S&P TD Silent 160/100 N, GENT ECco 100mm, TT Silent M 100, DALAP AP Quiet 100mm.
Thanks a lot 👍Setup. Ventilation

High heat in greenhouse, how hot is to hot?I built a 16x20 greenhouse with dual vents and a 24” exhaust fan. I hit a max of 122 (it’s 92 outside). I typically reach 105-110 on regular days. Everyone looks happy other than an nutrient burn issue. Can weed plants handle this kinda heat?

How to vent grow tent?Venting into large basement area separate from lung room. Averaging 65% RH in tent. How can I vent my grow tent out a century old red brick home's original basement windows discretely? Or, can I vent into an old (capped) chimney without removing the cap? Lung room is 6x10.

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

Help with airflow. I've got an extractor and 3 circulating fans. Would a powerful inline fan be better than the 3 circulating fansQuestion about environment here.
I've got a 5x5 tent. Total 46m area.
460m3/hr needed to be extracted.
Extractor fan is capable of taking 600m3/hr.
I did have in an inline fan but it's no longer working. Do I need another inline fan ?? I've opened two ports for passive intakeSetup. Ventilation
