just wonderin

hey whats up just a couple questions

Ive got a couple plants growing inside which is all fine and dandy but within the last month police choppers have been flying around scouting the fields like you wouldnt believe but im wondering since they use infered (sorry i have no idea how to spell that one) im wondering if they can see in the house with this stuff I mean I know thats how they find it in the fields I hear that marijuana has its own unique heat. I have no idea what the temp of the plants or anything so i dont know if room temp can make these things invisible or what. I dont even know if its legal for them to look inside a house with infered? but i was beginning to get a little nervous over it. does anyone know more about this?
My second question is a little more basic but my growing space isnt that big so im only doing 5 at a time and ive had all 5 come out to be males before which is shit luck i guess. But I would love to turn the light cycle to a flowering stage for about a week or two to see what I got going. then go back to a veg stage. What kind of flaws come with doing this? Once last year i left the house for a couple weeks and when I got back the top maybe 2 or 3 inches of the plants grew over the light and the tops started showing sex im wondering if maybe the bottom was still veg stage and the tops began to show sex? is this at all possible?? if it is it would relieve this whole problem you know what I mean. I dont know let me know what you guys think.
thanks

Well anybody can do a heat scan on your house, but I believe that they can't use that specifically to get a warrant. But I wouldn't be concerned at all with only five plants. Now to your second question, plants in veg will supposedly eventually show preflowers, I'm sure how long it takes, maybe a month or so. Somebody should back me up on this if I'm right, but my impression is that you can either wait awhile in veg to see preflowers, or you can clone your plants and flower the clones, as the clones will of course be the same sex as the clone parent, but I do believe that it is not the best idea to flower plants and then return them to veg, as it supposedly slows things down quite a lot.
