"I have an amazing growing journey with this strain. I started with 10 seeds of pack..All good, except the I found some dry leaves of it. Maybe my mistake on my part. Because I let on the direct sunlight. Maybe it was good on medium temperature. But all was great. You just really have to take an eye on your plants. Good for medical purposes, pains, relaxant and more. So amazing over all!"

"Plant grew great and got very big for me. Next time I would use a bigger pot for a long veg. She’s got a diesel smell and smoking she tastes like cheese and diesel. The taste is very much a love it or hate it, not a lot of sitting on the fence as it’s fairly distinct."
– Ronald Martinez
