Description from Crop King Seeds

Holy Grail OG Strain Information
Crossing Kosher Kush with OG #18 resulted in an indica-dominant powerhouse that frequently reaches between 20 percent and 28 percent THC. It is designed for those who want a heavy, traditional OG experience without any compromises. The high hits with a happy, mental fog before the physical side takes over completely. While it starts with a brief moment of euphoria, the primary goal here is relaxation. Because of its strength, it is best reserved for late evening use when your schedule is clear and a comfortable spot is nearby. Once it takes hold, the effects are long-lasting and consistent, ensuring you stay in that relaxed zone for hours without any sharp spikes or the effects wearing off too soon.
Myrcene and limonene lead the terpene profile, combining for a sleepy yet happy effect. You get the bright, sharp notes of pine upfront, while the heavier, musky undertones of the earth provide the foundation. The exhale is bold and slightly spicy, finishing clean while leaving a strong, lingering taste. It is a reliable choice for anyone looking to truly unplug, as the combination of high THC and classic Kush genetics provides a reliable way to ease into a tranquil, happy headspace.
Growing Holy Grail OG Strain
When it comes to cultivation, Holy Grail OG is a rewarding plant that shows off its lineage through a bushy, robust structure. It does not stretch excessively, but it does produce large, dense colas that might require some support toward the end of the flowering cycle. It responds well to training techniques such as topping or using a trellis, which help manage the canopy and ensure light reaches the lower bud sites. This variety is known for being fairly resilient, making it a solid choice for those who have a few grows under their belt. Expect a flowering time of about 8 to 9 weeks, with the plants giving off a very strong, pungent odor as they mature, so a good filtration system is a must. Proper curing is essential to bring out the full depth of the pine and woody aromatic profile.
