Oh, worse than that.... I have a 6" duct port into my flower room for peeking in from time to time when the lights are on. A 6" plastic pot fits it perfectly
and light tight.

I left the pot out of the intake... for 7 hours while the lights were off. Ambient light flooded into the room. SHit!

Oh well, NOTHING I can do about it but watch for signs of problems.
3 plants in full flower at 6 weeks..... 3 in early flower at 3 weeks.

THEY ALL LOOK BEAUTIFUL! I hope they stay that way.

Indoor light issue, not outdoor... sorry These girls have been under strict 12/12 with absolute dark and light for 6 weeks and today I left the door cracked open for 7 hours during the dark period... just noticed it. 2 hours before it goes back to lights on for 12 hours.
