I just got a might/might not work idea.

build a little room around a window, and set up your lights, plants, and everything. Flower/veg during your peak sunlight hours, with the blinds open, and your artificial lights on. Close the blinds during the dark period of 12/12. I know the plants would want to stretch toward the window but could you offset that with the placing of the lights on the opposite side?

I was just thinking of ways for one to get bigger plants without wasting as much electricity, and this is all i came up with. think it might work?

Sure, and maybe even point an arrow at the window.. this way your neighbors/friends won't need to waste much time figuring out exactly where your operation is!

Not to mention you will compromise the 12/12 regimin,because there is more than 12 hours of natural daylight. The blinds will not keep it dark enough. Don't forget that arrow towards the window!

Ga Grown!
