PapaBaerstarted grow question 5y ago
Hey Ho, so far I've been using my 2 small fans at the entrance and the exhaust in the middle. Since there's no air reaching the back and the circulation takes quite a while (smoke lingers for about 1 minute until it's ventilated), I wanted to ask which fan I should install there?

Have you calculated your room volume? Once you do that, look for a fan that can remove a CFM that is similar or more. The AC Infinity site has a great graphic to help calculate needs that includes how to factor in ducting, filters & lighting https://www.acinfinity.com/pages/technical-guides/grow-tent-ventilation-guide.html

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.Setup. Ventilation

Connecting 2 grow tentsI have a 16"x16" small tent next to a 48"x24"x72" tent. With 1 small plant in the small tent, is there anything wrong with ducting the air from the small tent to the bigger tent where my carbon filter is. Seperate intake and exhaust for each tent. Has anyone tried this before?

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.

Slowing a two speed inline fanCan I run a fan speed controller with a dual speed inline fan? My 4” two speed fan is slightly too powerful for my grow room. I’d like to slow the fan slightly but I have heard the these types of controllers don’t work with two speed fans? Any advice or what to buy to do the job?Setup. Ventilation

Problemas temperatura en mi cultivo 5ta semana de floración.My grow is going very well, but these last few weeks winter has started, and the temperatures indoors have changed, with the lowest being 12° and the highest 22°. It usually stays around 20°, and the substrate temperature is usually around 16°C. Could this be a problem?5y ago

Carbon filter sleeve needed?I use the carbon filter on the exhaust side. On the intake side, I have a dust screen mesh.
The tent is quite clean so that’s why I don’t see the need of the pre filter. Would also probably load the inline fan a bit too.
What’s you thought?

Yay, I ordered a growlight + tent + accessories! I'm planning to install all of this in my basement. I have a small window that I could use to send the filtered exhaust air to. but will it suffice to just get intake air from the basement itself? Or would I need an air purifier?
