When you have 26 milk crates full of gallon jugs of rain water and one of your gutters dumps into a series of three 55 gallon drums with sub. pumps.
When you can stare at plants for an hour non stop, just enjoying the scenery.
When you go into a pizza place with big 600° ovens and somebody says you smell a little 'skunky'.
When you're always thinking you could use a new electric line out of the breaker box.
When bud porn is as interesting as real porn.
When your HTGS bonus card has enough points to buy something big.
When your straight cousin who owns a garden store asks, 'what are you buying all the pots for, are you growing pot?'
