answered grow question 6y ago
Just had a quick look and that looks fine to me, I like to put the fan on a timer to give it a little break a few times a day. Unless it’s too hot with lights on, then I will have it off for a couple of hours while they sleep.

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.

In-line fan use
I’m just wondering how much to run an in-line fan. I’ve read every 1-3 mins, but I would like to know how long does it run in between those times? Is it constantly turning on and off? Do I need to put it on a timer? Thanks.

RH question! Huge veg phase plants
Air humidity increases during night time (up to 90%). I have placed carbon filter below the plants. Question actually is do I need to be too worried if I can get the RH level better within next couple days? It’s first week of 12/12 switch now. :)

Connecting intake fan to my tent's mesh for most efficient ventilation
So as a couple people suggested, I bought an intake fan, and am using it to bring air in from a different section of my closet. How can I stick the ducting to my tent's mesh? Is tape fine? Any other ventilation tips?😉😀

Smell at 2.5 weeks?
Is it normal for a Quick One to smell strongly at 2.5 weeks? I only have one plant, and moved it out of my bedroom to the spare room where there are fewer clothes. My partner could smell it downstairs and the plant only just got its 5 tipped leaves.

Smelly room, with filter should I be able to smell flowering buds?
I have a 3x3 grow tent with a 4” fan and filter. The filter is in the tent and exhausts into the room. I taped the filter to the line and line to the fan so no pinhole leaks. The fan is rated for 198 cfm. I have it on low because when it’s high the smell is worse.

Dehumidifier advice
I am looking for an efficient, non-electric dehumidifier for the grow room. Do you think one of these would work? Can you recommend anything specific? Are they effective? About 30m3 total grow room volume.

New Light? Find a way to raise light? More Fans? Combination? (Light: 44" above ground level | Tent Height: 63" Day avg: 78.6f) Should i worry?
What do you guys recommend as far as lighting for this tent? I have a 300w led light but at the height it's currently at it is producing a large amount of heat with my exhaust and two oscillating fans? I also have other plants in with my seedling so could the humidity cause it?

Fan vs Fanless LEDs
How effective are heatsink LEDs? I'm not sure if I should go with fanless (like Mars Hydro SP150) or with a fan (Mars Pro II Epistar 120). I struggle with heat, when the tent is closed it gets to 29-30 degrees with humidifier in full swing (HID lights) and I want to close it soon

Grow Tent/Room setup in the basement - dehumidifier or humidifier needed?
I’m planning a small grow setup in my basement and have a room that’s holding a steady 17–18 °C (62–64 °F) with about 55–58% relative humidity. My plan is to vent the exhaust from the grow box straight outside through an existing duct. Will I need a de- or humidifier? Thanks!

Humidity issues near flowering
So I installed an intraction (145 m3/h speed1) and aluminium foil on the pots but humidity is still hight like 75% when nightime and the lowest is 65%. Probably the water evaporates by the pots (drip, clay pebbles). I have no more ideas. Do I have to buy a deshumidifier? Thx !
