Sour D is an absolutely beautiful sativa. It's very uplifting and cerebral, and provides a nice energetic buzz. I cleaned my apartment on this and enjoyed every moment of it. Very long lasting but it does tend to have a more calm-like Indica effect after a couple hours, which was perfect for me. I found it greatly enhanced all my senses and made me quite introspective & creative. Depression and anxiety are obliterated. Enjoy everyone! 5/5. It doesn't get better than this.
MK Ultra is my go-to strain for insomnia. Definitely a very heavy Indica that melts away anxiety and depression, and allows for a restful sleep. It's relaxing, euphoric, and doesn't cause terrible hunger pangs like some other strains. It's also a very effective pain reliever and muscle relaxant, which is great for those who might be suffering with fibromyalgia and back problems, etc. I've tried A LOT of heavier strains like Chemo, PK, & N. Lights, but I keep coming back to MK because it's just that good! As others have mentioned, it has a rough inhale & exhale which is honestly the only negative, but it's such a minor detail given all it's positive effects. The taste is quite earthy with hints of pine. MK may be a bit too strong for beginners as it hits hard & fast. Full effects are about 15 minutes after smoking, so make sure you don't have anything important to do or focus on because it won't be happening once this kicks in:). This is a spectacular evening strain that I always keep in my stash. 5/5 highly recommend.
