Strain Profile

Karel's Haze

One of our easier strains to grow, you can expect mature flowers in 8-9 weeks. This is a really special hybrid, made from our Old School Haze and Chem Dog OG Fire, a variety that produces medium to large plants. Natural vigour produces fat frosty OG buds, so keep your eye out for those. And look for the fruity or gassy phenotypes. You can expect good yielding, frosty plants with a beautiful terpene profile, which are great for making extractions. We are ready to say that the Karel’s Haze is our new pride and joy. It’s one of the most delicious smokes you will ever have, with a layered taste of tropical sativa lime and a citrus touch with a dark gassy after-taste. Karel's Haze offers you the best of both worlds. A very smooth smoke but after a few tokes a head rush can be expected. Specifics OSH x Chem Dog OG Fire 8-9 weeks Hybrid Sativa 70%- Indica 30% Medium/large plants Tips from the Master Breeder. If you want this baby to produce for you, try to top your plant during veg (remove the growing tip). This will allow you to avoid single branched plants. We want big trees of course... Do you find mistakes or wrong information? Or is there something you want to add?
