I'm on 18 months supervised probation for Possession of drug paraphanalia. I had a grow light, cloner and timers.
If pot is involved, police can say anything near it is paraphanalia.....
On the other side, I had a 42 glass pipe collection and assorted hookas confiscated and was charged with paraphanlia, but the statute of limitations ran out on misdemeanors and the charges had to be dropped - never got the "evidence" back either, bastids.
Depends on the attitude in your area, if you have cops that were bullies in high school, they will try anything - others may ignore a lot.
My living will: if I can't tend me plants, just unplug me.
