if this is a dead topic, just let me know. (i tried searching thread titles) i've been reading about "light pipes" , a method being used to bring daylight into interior rooms of buildings not graced with exterior windows. they are basically tubular skylights (coated with reflective material) with diffusers on the interior end, which travel from rooftop collectors through attics into the building. has anyone tried these for small indoor grows? if it would work, you would need no timers or lights, and have no tell-tale heat signature nor electrical usage spikes or suspicious 12 hour cycles. i have found nothing on the net RE this anyplace yet. comments, suggestions, & ridicule all welcome (and expected) lol. i may try to build one myself and try it just out of sheer curiosity...
