it it possible? I don't want my babies to get confused and upset..would mirrors work as an alternative to a reflector?
Mirrors won't work at all. The reflection you would get from the mirrors wouldn't be beneficial for your plants whatsoever, should buy a roll of Mylar or panda plastic
Mirrors absorb tons of light, you'd see your plants in the mirror but it will be a huge waste of light compared to just flat white paint.
