I have thought of this before. But I tell ya what, If I was going to do it I would use mirrors and not worry about hot spots. Let the sunshine in baby. LOL a 60"s thing.

Anyway, I bet you could pull about 8000 lumen's off two mirrors, problem is the sun moves and you would only get light a few hours a day. You are going to need like minimum of 16 hours for veg and 12 for flower.

Indoors is indoors man. we gotta deal with lights and timers. to hit the right photo periods to make cannibals do what we want.

My opinion.

BTW,

Welcome to rollitup and keep thinking out of the box, Thats cool.
