got them from a mate he said they where but not to sure to be honest the rvk is 20cm diameter i think do i really need a carbon filter as i am growing in me loft an the air goes out throw the chimney

so not bother about the smells not in my house as long as the neighbours r not getting there roof or aerial done then i should be ok
an how can i be sure that the chopper copter cant see with her heat seeking eye

Well, some plants are stinks and some you could get away with, but this is about minimising risk so eventually you need a carbon filter, but at the stage of seedlings you are probably ok (I know others will lynch me for that).
With the helicopters, you need to insulate your room well and make your heat sig as "normal" as possible.
Accoring to police guidelines, heat pictures arent enough for a Police visit and raids are supposed to be intelligence driven - nosey neighbours etc
So the trick is to keep everything to youself. No showing "mates" your beautiful crop.
Id plant them all, weed out the males, carefully take cuts, label which plant they are from (i.e. Nothern lights 1, NL2, NL3 etc) flower them and keep any that are to your liking that grow strong and/or fast.
These will be your mothers and from these, you can keep your grow going pretty much indefinately and your only cost then will be your leccy bill (dont steal the leccy, you'll be in shit if you do) and your nutes.
How are you thinking of watering them?
Lugging bottles up to the loft gets to be a pain after a while.
