Carbon filter issue, cant find one in my country

Hi guys this is my first grow!
I am thinking of a wooden cabinet 80 cm in length 70 in width and 120-130 cm in height. I will only be going for auto flowers as i am not sure what else would i be able to grow in such heat here.

major problem is the activated carbon filters i will have to use the air purifier refill activated carbon filters and hepa filters as i am not able to get the cylindrical one here, these guys suck up to 0.3 microns i am not sure if that is enough. i will be posting images below. i am going to make a bundle of both and wrap it from the sides using aluminium tape. i will be mounting these in the side cabinets shown in the pictures and the attach the exhaust fan.

will be going with PC fans, will that work? and how do i connect all of this in one main socket do i use a motherboard or something?

please recommend good grow lights preferably LED's?

PC fans and HEPA filters do not equate.

I have a 12v PC fan blowing on my plants and its not powerful at all, if I put a piece of filter like youre thinking I doubt it would blow at all.

Check this thread out, there are so many useful threads from years and years of posting but this one came to mind.

ok then probably keep the pc fan for intake add a proper exhaust fan and DIY my filter.
Hopefully works well i am also thinking of placing the non electric carbon filter bags one in the grow area and one in my room, do you think the non electric ones will suck the odor?

for example this:

Key Features of Dr. CHARCOAL
The surface of our activated charcoal contains micropores — with pore sizes of less than 2 nanometers — that absorb those nasty odors and impurities present in the air, just like a sponge, leaving clean and fresh air outside the bag. Each single gram of our activated charcoal has a surface area of more than 1,000 sq. m., with each 200 gram bag covering an area of as much as 10 football stadiums or 10 cricket grounds. Yes, you read that right! Depending on the usage and area covered, Dr. CHARCOAL can last for more than a year when reactivated by placing it in the sun for one hour about once a month.

If i go with the 4" inline exhaust fan and then use these rectangular carbon filter pieces do you feel it will work?

Need this too. Thanks to this thread.

With your setup you most likely wont need an intake fan, just run an exhaust fan with passive intake.

Where in the world are you that doesn't have either amazon or ebay?
Cant recommend an LED until I know a rough idea of where you are.
But for cheap (not good ) leds you want 50 real watts per square foot. For quality efficient LED you want 30w per square foot for flowering.
I would recommend a HLG135w kit which can crack 150w on full whack but its ment for 2ftx3ft max and I think your a little over that space.

You can run passive intake.
If you want a link to a really quiet fan I can link one but im in UK so pointless me linking it if your not at least in Europe.

Can you not order things on the internet?
