help me

Im about to grow a plant but i need help ive recently bought pc fans for my grow box but
the suck at extracting air ive filled a toilet tube with activated carbon and the pc fans suck
at extracting the air i need help

I don't think those fans are built for pulling air through a filter.

get bigger fans, your not building a computer your growing cannabis

what sort of fans ,

welcome, when I'm in doubt do an online search, for indoor grow fans, I grow outdoors

Even the inline fans you can get at home centers are better than PC fans.

Get a bigger toilet

you can make a filter with a pc fan
I have a step by step but its in a word doc, anyone know how to upload this ?
