I can answer the "why..."
Because often, people (like draig and I) have to have the lights ON only at night, because of the heat...
IF we aren't here- or awake, or forget (*whatever*)-- then we might need to "pop-in" for a minute to trim, check a pH or snag a clipping....
Never TRIED the green light-- but we do not interrupt their beauty sleep often enough to cause a problem...yet.
No need for revenge, just sit back and wait.
Those who have hurt you will screw eventually themselves; and if you are lucky, God will let you watch!
Through What we create- we are immortal.
