so i got a 10 ft 4" duct that i want to cut to pieces of curved duct and make lightproof passive intake holes in the flowering chamber. question is, how long do i need to cut the duct to achieve a lightproof curve? the the duct is black from the inside. would 1 ft suffice? i need to begin cutting, so all help is appreciated ASAP, thanks!
