Slyder is a pure Indica marijuana strain. Indica strains are the kind that get you really stoned, to the point where you might spend your time locked on your couch or sleeping. Many marijuana patients use it for pain relief, and as a sleep aid.
Slyder is a dark green bud. It's covered in crystals and green hairs. It's pretty dense so it is best a use a grinder. The keif you'll collect at the bottom of your grinder will be pretty potent. Slyder comes from a line of very pure Afghan strains. The effects are similar to smoking hash.
Slyder isn't the kind of weed you smoke before work. It's the kind you smoke in a blunt contest, because it's potent enough to weed out the weaklings (pun intended). So call around to your local areas and see if you can find some, or learn how to grow some for yourself.
