I enjoy this strain, here's why. Easy clone, 100% success rate. While flowering it gives a light citrus odor, pleasant not pungent. Bright buds with light yellow tint.
Helps me with lower back pain,relieves the pain some and takes my mind off it, good relaxant. Couch-lock if I smoke too much, but I'm no heavy-weight. One and done should be my rule.
I mix this with a sativa to balance the effects, I can't smoke just SIS every night as I will begin to be drowsy in the morning, and I stop smoking at 8pm... give or take. And if I smoke too much I get dizzy, that's not cool. Those are the only reasons for my 4 out of 5 star rating. If I could give it a 4.4 I would, based on it's effects and if taken for those effects.
Not sure of the parents, so it may only be 70-80% Indica. I can say by the effects of SIS that it is predominantly Indica. And not to be related to Island Sweet Skunk, may have a similar odor in flowering stage, but SIS is not uplifting at all, don't smoke SIS if you have something to do, anything. It just has an annoyingly similar name as ISS. Also, SIS grows short and dense as opposed to ISS. Perhaps SIS is descendant of ISS.
Smells like hay when cured.
