Pinholes in secret jardin Dark Rooms

I've heard alot of people say they got tiny pinholes in there DRs, n i was wondering doesnt that affect the thermal imaging aspect of it??? cause the heat and light can still escape and reveal itself thru the holes

somebody out there gotta know something....

The holes are generally there because of stiching, but If you're growing in a well insulated area, they don't matter. if you're really paranoid, stick some foil tape over any holes from the inside.
