Frequently Asked Questions

Is Grateful End OG suitable for beginners?

While it is relatively easy to manage, its vigorous growth and heavy buds require some basic knowledge of plant training and humidity control to prevent mold in late flowering.

How much does it stretch during the flowering transition?

Being a medium-high plant, you can expect it to double in size once you flip the lights to 12/12. Make sure you have enough vertical space or use a SCROG net.

What are the dominant flavors?

Thanks to its high limonene and myrcene content, you will experience a strong burst of tropical citrus mixed with sweet floral pine berries on the exhale.

Personal Experience of Pevgrow’s CEO (Alan)

When I first popped the Grateful End OG seeds, I was looking for something that could replace my usual heavy Indicas but with a more complex flavor profile. The lineage immediately caught my eye. During veg, I noticed it grew with incredible vigor, so I highly recommend topping it early to keep the canopy even. Once it hit week 5 of flowering, the resin production went completely off the charts. The smell in the grow room was an intoxicating mix of sharp citrus and deep pine. I prefer vaping this strain at night; the 30% THC is no joke and delivers a profound, melting body relaxation that is perfect for disconnecting after a long day. If you want top-tier bag appeal and a knockout punch, this is a must-grow.
