About Grandpa Larry OG
Larry OG and Granddaddy Purple combine in Grandpa Larry OG, an 80% indica, 20% sativa hybrid grown out under a moderate difficulty rating by Grand Daddy Purp. It stays compact indoors, topping out around 90-120cm, which makes the 400-500 g/m² yield especially efficient for the footprint. Flowering wraps in eight to nine weeks, a fairly average window given the indica-heavy lineage. THC lands between 16.8% and 19.7%, respectable without pushing into the upper tier of modern hybrids. Between two OG-adjacent parents this heavily documented, Grandpa Larry OG reads as a plant built for growers who want predictable size and yield more than a headline THC number.
