Dark Hearts Nursery’s Fire OGHumboldt OG
Well-balanced OG hybrid with large, dense, resinous buds and very high THC production.
Emerald Fire OG Feminised is a well-balanced cannabis hybrid that was bred from a cross of Dark Heart Nursery's Fire OG with Humboldt OG. Emerald Fire OG is an F4 strain that takes 60 days to complete the indoor flowering cycle. Outdoors, harvests are ready in the first half of October in northern latitudes.
This strain's mature buds are large and very dense, covered with orange hairs that resemble little licks of flame. When smoked or vaped the buds produce a pungent, earthy and citrus quality with notes of pine and lemon.
THC levels are very high at between 23 - 28% with very low CBD of 0.04%. The effect is relaxing while also being an uplifting high. Contentment awaits the lucky consumer.
