Hey man you said they are on your deck well i have read in a few diff logs where ppl had a couple plants go herimie from there deck lights or porch lights night lights ect ect. Anyways just thought id give ya a heads up if you have a deck light or anything like that outside around your plants you run a good risk of them going hermie.

So either make sure they are turned off or either put your plants in your shed at night to make sure they get total darkness and don't go hermie. But if you have nothing like that around and its real dark outside on your deck then i would not worrie about it.
