The plant from what I have read dose give off a skunk scent, on a scale I would guess a 5-7 on a scale of 10. You do want to keep the plants as cool as possible so that the smell stays down. The more heat you heave the more the plant will give off turpines (smell particles). Also try to keep as much light on them as possible. I have seen guys place the plants under 120 watt CFL and come out with some tasty buds They look fluffy and not very dense which is why you want to use as much power as you can, something like a 400W HPS will do the trick.
