light deprivation

i have a skunk 11 and 3 dance worlds (rqs), outdoors,
they could do with another few days to mature,
but i had to take them into a shed 3 days ago because of rain.
they had great weather all summer until now, but the rain has hit and isn't going to stop for a few weeks,
maybe a sunny day in the middle of the week, but thats all.
i had them under polythene but i was afraid they would mold in there,
they've outgrown it a bit. but since i've left them in the shed, they've really fattened,
they're getting a lot of indirect light, but not a whole lot of direct light.
how long can i let them in there before lack of light causes damage?
the mail problem i have here is, if i take them in and out, people will see them driving by, so i gotta leave them where they are for now,
i don't really know if trichomes and pistol color have the same rules outdoors, so i have no idea how close they are to finish.

here is some pics of the dance worlds 3 days ago,
and the skunk 3 days ago too, she's a monster,
the dw's are for a friend's dad with osteoporosis, and maybe some for me, the skunk however, shes all mine.
