ALSO, owning a grow light is not illegal. turning it on is not illegal. what is illegal is the plant. remember this, this is very VERY important.

unless you sell directly out of your house, or they see your plants, or someone signs and affidavit saying you have plants in your house, it is kind of hard for the "man" to catch you. a FLIR camera is not enough evidence. unless you are planning to run a 300 plant grow, carrying ridiculous amounts of soil and fertilizer, and living by yourself wasting like 600 dollars of electricity a month, and having a lavish, extravagant lifestyle without any sort of legitimate job.... you'll be fine.....
