Help needed.

I have a small problem...I live in central Cali and I currently have two females that are like 3 weeks into flowering. I'm using one main light source which is a (4) socket adapter and a reflector which is above the plants. Then I have one drop cord hanging between the plants to give light to the lower branches. 5 cfl's a mix of 23w 6500ks and 26w 2700ks. These are currently in my closet with a light timer at 12/12 and a fan.

Here is my problem...When I started these girls I did not plan on any visitors for the holidays but now I have my older brother and our parents coming to stay with me for 5 days! I don't know what to do with my girls...they cannot see them since they do not know about them...I was thinking that I could transfer them outside behind my shed under some larger trees while they were here then as soon as they leave I would bring them back inside under the cfl's to finish flowering.

Will my plants survive the cold? To give better location of where I'm at I live in the valley of central callifornia where the past few days have been extremely foggy, hardly any sunlight, and there has been frost. It's for 5 days and I cant think of anything better...any help is greatly appreciated.

are you sayin u iz gonna move dem into da shed with no lights ? 5 days u'll have hermies br0 i say move them to shed with da lights and a small heater they'll be fine for 5 days

Well, since they're flowering you don't want them to get any more light than the 12 hours or they may try to go back to veg. Maybe get some pvc and build a small makeshift grow box, you could get some black plastic or whatever you have to use around it as long as it's opaque. Then maybe put some small desk lamps in there for your lights?
