Ventilation Concerns - TD 160/100 with Rhino Carbon Filter

Hi people, really new at this and my set up is a result of online reading.

My concerns involve 'Very silent' ventilation?

Here is my setup

Grow tent 5' height x 3.5' wide x 1.5' deep so about 28cfm???

I am using DormGrow G8 450 LED light which is both veg and flower, I will add their red spectrum UFO during flower. Very little heat! Small noise from fans.

Using a hydroponics system with airstones sitting on vibration mat and polystyrene packaging used to box a washing machine so pretty thick.

As it stands just now only opening it up at night to change air about and keep it slightly open at top and bottom during day. LED lights crazy purple bright light!

Silence is the biggest thing for my grow! Everything right now is cool on that front as it stands.

I was concerned about ventilation and when I get to flowering obviously the smell..!

I am looking at S&P TD 160/100 silent fan and started looking at rhino carbon filters.

The TD is 100mm and is 2 speed (without the speed controller which S&P manufacture and can be added).
2 speeds are 180m3 and 140m3 per hour. 24db and 21db on the same settings.

I would hope that using/adding the speed controller I can reduce the speed/noise and still have enough juice to extract/draw in air through carbon filter for my 28cfm approx.

I was also going to use very short run of acoustic ducting - (best quality suggestions please?)

I was going to build an acoustic box for fan also! Just to further reduce noise.

And because of the size of tent I was going to use speed controller for the fan as don't want to exchange air to fast, read this can be bad also?

My questions are is summary:

I am correct to think I defiantly require ventilation?

Will the TD 160/100 be enough or more than enough to extract through carbon filter and at same time draw air in through open bottom and vents in tent?

Will this fan work with carbon filter and what size should I get, noise being biggest concern?

What is the best acoustic ducting to use and what size? I have read stay away from Euro stuff and get stuff with plastic lining in between layers?

I only want to use 1 fan and this will be to extract, I will keep vents and intake parts of tent open to draw fresh air in, will this be ok?

Will this exchange air to quick even while set low on the speed controller?

Anything else I should be mindful off?

Anybody got good experience and knowledge of this?

Thanks in advance

Peace x

Anyone?

I think you'll be ok with 1 fan if you keep some areas open for just ventilation.
I would still add a small fan inside the tent to keep air circulating.

as for the noise control something as easy as a cardboard box around the fan should help

Thanks, I had also read a cardboard box around with some insulation would be fine.

What's your thoughts about the size of fittings going to filter? Should I make them bigger to reduce resistance from the filter to the fan?

Any advice on the acoustic ducting?
