Will this fan work for my wardrobe grow?

Hi guys, I purchased this 80 m3/h 15Pa fan for my future wardrobe grow. The fan will be delivered to me in about a month.
According to this calculator, my wardrobe's volume is 0.7488 m3 and I need a fan that can move 66 m3/h of air.
Well, the fan that I purchased covers that requirement plus some extra, but since it looks like a duct booster fan, I am worried if it will work with a small carbon filter???
Check out the images below.

Those fans don’t carry enough static pressure to pull through a carbon filter. They are a bathroom ventilation fan to remove excess moisture from a shower area.

you should look for something like a 4” SYSTEMAIR RVK100A1 and speed control it if needed.

you also haven’t mentioned what lighting you’ll be using as this will also play a role in whether your fan is capable of cooling and replacing the air within your wardrobe.

Even if you plan on using LED they still produce heat for the decent panels.

Hi, jondamon, thanks for your reply.
I was looking at this ventilation kit, so I decided to model my vent setup after it. The kit from the link uses a very similar bathroom fan, which some reviewers claim works great with a carbon filter and others claim is underpowered... Not sure what to believe.
I guess the only way for me to find out whether my fan would work or not is to just wait for it to arrive and do a test.

For my lighting I will be using a homemade LED panel that consists of 15 regular E27 LED bulbs with their globes removed (see photos below.).
This DIY panel does produce some heat, but not much.

What is the power draw of each bulb?

Each bulb draws 9 Watts from the wall. The total electricity consumption of all 15 bulbs is only 135 W.
Each bulb is rated at 806 Lumens with the opaque plastic globe on, so, it is around 1000 Lumens per bulb with the globe removed. The whole panel is around 15 000 Lumens - enough for 3 square feet of grow space. Tested with great results.

Thats enough lumens for seedlings. Your yields will be terrible but it'll work. Your wardrobe is very small and tall so your fan will work cuz your area is 2.5' x 1.6' x 6' so at only 22 cubic feet the fan would work with no filter and minimal ducting. You should add a small fan blowing on the girls to help move air around too.

Especially with a low pressure fan, a small filter will reduce flow. If temperature and humidity are under control, I've seen excellent growth with very little air exchange, but circulation in the grow is needed. 29C air temp is good and look into VPD.

I already grew two autoflowering plants under this same 15 000 Lumen panel.
One plant yielded a 800ml jar full of hard nugs. Not sure how many grams it was, as I never weighed it, but I assume it was around 25 grams. Not too bad for a small autoflowering plant.
The other plant was too sensitive and was plagued with problems - it yielded a lot less (maybe 10 grams of leafy bud), but this was not because of the lights. It was just of crappy genetics and was sick for the last 90% of its life cycle.

Personally I would never advise a duct booster fan for use with a carbon filter as they are designed to remove air with no Obstruction.

you also realise that plants will become sick and fluffy buds will develop from plants that aren’t receiving Enough light.

personally if it were me I would look to run 1 photoperiod plant and scrog it to make best use of your area.

training the plant to stay low gives you greater space to dissipate some heat if you get any.

those LED’s won’t give you the greatest penetration so short SCROG’d plant occupying approx 1.5ft x 1.5ft Scrog net should be manageable and return a decent yield compared to just growing 2 plants in the same space and allowing them to get tall.

Yeah, I suspect that this booster fan won't work too well when combined with a carbon filter that causes a major air flow obstruction. We will see... If companies are selling kits that use a booster fan, then maybe these vent setups work for small grow boxes like mine. And since no body has experiene with these, there is only one way to find out now. I will just do a test run and see how it goes.

BTW, the plant that developed fluffy buds was sick from its early stage of its development. It was still a seedling when it first started showing problems. Lack of light was definitely not the issue. It was a crappy strain and I think I may have nute burned it on top of this.
Both my plants were trained (LST).

Companies sell them in kits so that instantly you have to buy a second fan.

Plenty of people over the decade I’ve been here have tried the “kits” Including tent kits that are sold with the wrong types of fans.

Interesting, I just noticed that Walmart also sells a vent kit that uses a bathroom fan. The kit even has one positive review from a happy buyer, LOL!
Can't wait for my fan to arrive, so I can test if it will move any air at all through my carbon filter.

I was thinking about what nc208 said about the Lumen count on my light fixture. In my personal experience 15 000 Lumens was plenty for growing two plants, but there is actually more to it.
I believe light bulb Lumens are measured in the factory at 33 centimeters of distance from the bulb. So, in my case the total is 15 000 Lumens at 33 centimeters. However, I do not keep my light fixture at 33 centimeters, but I keep it much closer - at 15 centimeters from the trained tops of the plants, so the intensity of the light is considerably higher than 15 000 Lumens and is probably close to 30 000 or even more.
Also, I will be using Mylar for the walls, floor and ceiling of my grow cabinet. Mylar increases the light intensity by extra 20%.
So, the minimum Lumens that the buds will be getting would be somewhere around 36 000. That's ~ 12 000 Lumens per square foot.

I just measured the Lumen output of my homemade LED light fixture.
It was 38 000 Lumens, lol! Two and a half times more than my guesstimaton of 15 000.
And that was measured "dry" - without Mylar or any other reflective materials around the light. With Mylar, the output will reach 47 000 Lumens.

Have you had a grow from those lights?

I think 135 watts is able to veg 3ft square
But I believe it's 3x2 when flowering, I'm probably wrong though ha.

they make a 1600 lumens led bulb that draws 13 watts you may want to get those also mix it up with 5000k and2200k
