Watch out for the grow lamps. The electric company watches for electricity usage increases consistent with running grow lamps, and notifies the government, who then sends in the DEA to bust down your door and possibly murder you without you ever having had a chance to tell them that what you're doing is perfectly legal.
I had two green Iguanas in their own big separate housing units with day lights and night lights going 24/7 for almost 10 years. No one questioned our increases in electricity.
I never thought about that, but no one ever questioned us.
I was a democrat when the Feds started breaking into homes and killing people. Now I am a Republican and it seems to me that nothing has changed. How do we explain that to our kids?
Plus, the DEA takes nightime infrared photos to see who's home lights up. After that, they subpeana your power bill. If it is too high, in their estimate, expect a no-knock raid.
