erm. . . dont know if i being silly here but i cant think of anything to downsize my 6" ducting to fit 4" carbon filter is this actualy possable or do i have to buy a filter to fit my fan.
sorry if it dont make sense pretty baked

you can buy "reducers" from grow shops, but a cheap and easy way.......plant pots and gaffer tape

For emergencies only:

Use a cone shaped traffic cone, the larger ones, it only takes 5 minute drive before you find one.

With plenty of gaffa tape it is possible to do something temp.

But it would help if you could reduce the speed of your fan as well, else it will probably be really noisy else, try it and see.

haha plant pots and gaffer tape awesome answer cheers mate

Buy a reducer, I've done the plant pot thing before and the gaffer tape fails after time and you end up with dead plants (Well almost) use jubilee clips, gaffer tape becomes an awful lot less sticky when heated by warm air it almost cost me a crop.

Plant pots can't be jubilee'd to and ducting without jubilee's is pissing in the wind IMHO.

Reducer + jubilee's ~£10, actually not killing your plants because you weren't a tight arse on such a simple and important thing priceless.

6" fan with a 4" filter



Owd

The plant pot idea, i picked up off this forum and it does have it's drawbacks. But for an emergency, it's a bloody good idea .

how come mate

bump for owd

Because a 4" filter will suppress the fan too much and if not controlled will pull too much air through it too quickly so not doing its job

Owd

true!

It will just suck the life out of ya filter.

Get a 6" cf.

Hantshaze........

cheers guys reallyu appreciate that best get saving then hey haha thanks again

Owd has it allright. I use a 10" filter on my 8" fan.

Ya learn something new every day....... guess it's common sense really Sorry for kinda miss guiding ya yayaya.

Beware a 6" fan is HUGE when compared to a 4" one.
Get ready for something double the size in every way apart from the hole at the end .

Lucky we were taught maths at school!

my 5 inch filter has a 4 inch inner tube ,fan is only a 5 inch tt though.

plant pot thing works fine if you use ally foil tape but as said gaffer is shite.
