Gelato packs a real punch. It somehow manages to both relax you and focus you. You can take it before bed and it'll knock you out, or during the day to get ready for a hike. One of my favorite strains.
It definitely gets your pulse going. Pineapple seems to be a pretty invigorating strain that felt it loaded me with a lot of potential energy. Some people have gotten some cannabis-induced anxiety from this strain if they don't have a sufficient way to use up that energy. But that makes this a great strain for daytime when you're getting ready for a run, a hike, or anything that expends a fair amount of energy. All in all a great energizing strain.
Definitely great for sleeping, generally a great relaxing strain but I've gotten some weird headaches after using it sometimes. Seems to be a pretty uncommon problem though.
