I am not a super lover of Skunk strains. Not that they are bad, but they are just not my favorites so I really have not grown all that many so maybe your question could best be answered by a true skunk lover.
Oddly enough, not counting the early days of Skunk when some smelled like pure road kill, the strain I have grown that had the most potent skunk odor was one I would not really have expected it from and did not have Skunk in it's name.
I purchased a cross from a Canadian amateur breeder that went by the name of Sweatleaf who was really very talented and who sold his gear on the old, and now long defunct, Cbay auction. It was a G13 X White Russian cross. I grew it on my deck one summer and depending on where you were and which way the wind was blowing, or if it was a calm day, if you were anywhere near my house it smelled like a skunk had just recently sprayed something. It was amazing. It was as if at night skunks were coming up on my deck and spraying my plants. If I had neighbors at the time I might have had a real problem on my hands.
I have read that GreenLabel Seeds - Skunk #1 is supposedly the original from Sam the Skunkman, which is questionable, and that if growing it indoors odor control is really needed because it is supposedly very skunky. The only place I know to find it is at
http://www.azarius.net/seedshop/ and they have shipping restrictions, will not ship to the U.S. or several other countries, plus I cannot swear to how reputable they may or may not be. Possibly it can be found elsewhere if you want to give it a try ... but I cannot endorse it from personal experience. I can only say what I have read in forums and also the advertising copy, which always has to be taken with a grain of salt.
I have grown Sensi Seeds Skunk #1 and it was pretty skunky. Not like the first skunk strains I ever ran across or the G13 X White Russian I grew, but it did have a distinct skunk odor, and it was pretty good smoke.
With a little luck possibly a true aficionado of rank smelling Skunk strains will see your message and be able to better answer it.
