Kosher KushThe OG #18
A winning cross of 2 time Cannabis Cup Champion Kosher Kush and Multi Champion The OG#18

This cross produces large resinous buds that reek of OG#18/Kosher goodness! The Holy Grail Kush is great for the beginner as well as the master grower. She makes an insanely aromatic plant with a strength and yield not to be matched. The Holy Grail Kush will demand the highest price of all the OG Kush Hybrids and the bag appeal is second to none. Several High Times staff were heard talking of how superior the Holy Grail Kush was in looks, smell, and taste. Please be aware of a very strong smell.

Summary
Germination Rate
Plant Structure
Flowering Time
Yield
Smell
Customers report mixed germination success, with most paid seeds sprouting reliably but complimentary bonus seeds frequently failing to germinate, creating inconsistency concerns. While some experienced growers praise the strain's dependability compared to alternatives, the recurring germination issues with free seeds have disappointed many users. Overall, germination performance is generally positive for purchased seeds, though the quality gap between paid and bonus seeds remains a notable drawback.

Holy Grail Kush Feminised Seeds
I have germinated many seeds of many strains from seeds man. I have never had a problem before this. I'm bummed cuz this one of my favorites. my germ rate is like 90% So I wont complain too much, but these are pretty expensive. 3/3 didnt even pop or grow a tap root. very disappointed but I will not bad mouth seedsman. even when these didnt germ. I germed 5 other strains with no issue at the exact same time. so I chop it up as something that happens sometimes maybe it was jus abad pack. but u asked my opinion you got it

Frequently asked questions
Is this strain suitable for my growing environment?

In theory most strains can be grown outdoors, indoors or in a greenhouse but how well they perform depends on the more exact environmental conditions. This is most important outdoors where climatic conditions can vary widely, so please check the strain information carefully. If your climate is more extreme or growing season shorter you should choose strain that is specifically adapted. Indoor and greenhouse environments can be controlled and made suitable for most strains although space can be a factor for strain that grow very large.

How difficult is this strain to grow?

Growing difficulty varies depending on a strain's resilience, structure and environmental needs. Some strains are more forgiving and better suited to beginners and a range of environmental conditions, while others may require closer control of factors such as light, humidity, temperature and feeding.

What can I expect in terms of cannabinoid content and yield?

Our product information and that provided by suppliers can be an indication of potential levels under optimal conditions, and it should not be assumed that results can be replicated in all conditions.

Is this strain suitable for beginners?

Strains described as beginner-friendly, easy to grow or resilient, in particular Autoflowering Feminised strains, are generally more manageable for less experienced growers. These varieties are often a more reliable starting point than more specialised genetics.
