The Underchunk is an indica dominant hybrid created high up a ridge in La Honda, California in 2013. Its genetics consist of Tahoe Thunder (ATF x Tahoe OG) and Deep Chunk (Tom Hill). Plants show medium short internodes, with strong branches and dark green Afghani leaves. Buds were chunky, full of trichomes and smelled of piney, lemoney musk. The male Deep Chunk used in this cross was healthy and vigorous, turning slightly purple near the end of flowering. The Tahoe Thunder female was exceptionally vigorous and had a pine/lemon aroma.
