Dehumidification
GreenbudLifestarted grow question 4 years ago
When the outdoor air dehumidification fan runs it produces a periotic negative pressure in the grow room. What is preferred: a negative or positive pressure in a grow room for this method of dehumidification?

Urrrrrmmm, not to sure what you mean, if we use 'passive' air flow then slight negative is preferred, the extractor fan creates negative pressure as it takes stagnant stale air out while 'sucking' fresh air in to create a cycle, to me personally unless it's sealed I would prefer negative so I 'know' it's pulling fresh air in, I wouldn't of thought this would be any different if you have a dehumidifier in the tent as well, you still want that 'fresh' air coming in, hope this helps happy growing 👍

Relative humidity is low here so, dehumidifier is a waste of energy for me. Better to blow air into room or suck air out of room or does not matter?

How crucial is an exhaust fan and a carbon filter?I cant find anything in my country as a kit, but would buying them piece by piece work?
Example something like in the photo connected to an air duct and then to a carbon filter?
Or if the exhaust fan is not crucial? how can i get rid of the smell in a cheaper way?

Brauche ich unbedingt einen (Schwenk-) Lüfter in meiner Growbox?Habt ihr schon mal ohne (Schwenk-) Ventilator in der Growbox angebaut? Wenn ja, welche Erfahrung habt ihr dabei gemacht? Ich möchte nur ungern einen Ventilator einsetzen, weil das vermutlich die Lautstärke der Box deutlich erhöht. Schon mal vielen Dank für eure Erfahrungen.

2x2 Circulating FanWhat is the best circulating fan for a 2x2 tent available on the european market?
I bought a Secret Jardin MO20 oscillating fan, and I highly regret it because I have read several reviews mentioning that it can catch fire. Is there any other good alternative for circulating air?

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.

Best way to keep a tent in the loft coolCooling the loft... so I've got my tent in the loft, I have a 4" inline extracting from the tent and a 6" inline feeding air into the loft. This works perfectly the majority of the time.. I can keep things at 25°c with ease. But on hot days the tents gets too hot....

How to deal with high (80% ) humidity during flower without dehumidifiersFirst time grower,
I'm in W-Europe and will have around 21-27°C, 75-85%RH in my 70x70x160cm tent, Not more humid than air outside it.
Getting a dehumidifier isn't an option for me.
Any advice on how to still manage through mid to late flower from someone who's in the same boat?Setup. Ventilation

Would it be possible to have a closed loop ventilation system?My tent is in a garage that gets very cold, i need the fan running so i have constant negative pressure so there is no smell. Could i just have the fan extract back into the tent with a CO2 bag in there? Heat shouldn't get too high, and only other thing i could think of was CO2Setup. Ventilation

Can't vent exhaust fan outside, is this a problem?I have my 2x2x4 tent in a closet, with a 4" carbon filter inside the tent and a 4" inline fan outside of the tent, exhausting. But I have no way of directing the air to outside or even out of the room. Will this be a major problem for me? Room is otherwise AC'd via central air.Setup. Ventilation
