According to "The Big Book of Buds", Island Sweet Skunk came to Federation by way of expat Vietnam veterans who settled on Vancouver Island in western Canada. The parent is a 1970's California Skunk #1 strain which was referred to as "Sweet Skunk." Stabilized outdoors.
I can't wait to post them. I'm getting rid of the Big Bud in a couple weeks. I got the Shiva Skunk to take her place, just testing it out now and keeping the NL pheno. I like it a lot more than the Big Bud and I lost my Shiva that I had for 10 years last summer when one of my 40 gallon resivoirs cracked and flooded the downstairs neighbor and had to leave that place. Can't wait to get it back!
It's federation's seed version of Spice of Life's(breeder Steve) sweet skunk; which itself is reputed to be the BC grapefruit clone by a nl/haze. The "sweet skunk" is actually a specific clone that Steve ran in 1994, and is still floating around the BC area.
Legends seeds has s1's of the original clone; direct from Steve.
