advice please on my plants

hi there
1st time grower here and although I have visited these forums a lot, i just registered today to ask a question that i can't find an answer to.
I planted 2 in august. I'm not using any artificial lights, just natural beside the window. 1 is 30 inches the other 24. Now the plants look healthy and have a ton of vibrant green leaves, but no sign of flowering yet. I had them in my basement for a while in a closet with a flourescant but there is no heat as such down there and I would say it gets down in the low 40s when its freezing outside. So i decided to put them beside the window in my bedroom Well I can't keep them there as I have kids and although they cant actually see the plants, they keep thinking there is a skunk in my house.
So, my question is, what do i do from here? how do i get these guys budding. atm they are getting a normal days sunlight (6.30am-4.40pm) with some bedroom lighting on and off until about 12 at night. I know this is probably a messed up cycle but any advise would be greatly appreciated.

The bedroom lighting will screw them up, guaranteed. You need to build a box with lighting control.

have you considered getting some CFL and setting it up in youre basement? you dont need to have all the fancy mylar and stuff to make it work, just get some 26 or 40 watt cfl from walmart or something and set it up with a regular light schedule. 12 on 12 off if you want to start to see "bud" and make sure you dont have light on the plants in the dark period. so try to have the 12 off when you are sleeping or while no one is home to disturb them.

they key is to have constant light with constant darkness, not interrupted by the other.

and if heat is an issue the CFL will produce some heat, not a crazy amount but still some heat, and if its a little cold maybe you will get purple bud lol

To flower you must have 12 hours ( approx ) of absolute dark time. ANY light during this time will keep them vegging, and will never flower.
You have a couple options, but the most simple would be to place them in the closet or other dark space during this 12 hours. Not very convenient though.
As far as the other space you have , some indicas will take low temperatures at "night", but if you are using bag seed, then I wouldn't try.
