Ultra Sour


About this product
This Big Bag of Buds is bound to surprise and delight. On the outside it’s a shiny one-ounce bag, that delivers the quality you expect from BBOB: Big Bag, Big Buds, and Big Terps. But inside it’s got two different strains freshly sealed in their own 14g bags! In this case it’s 14g of Ultra Sour, which is a sativa-dominant strain known for big sour and diesel aromas, as well as a separate 14g bag of indica-dominant GMO Cookies, which we all know delivers dank and musty vibes, with notes of diesel and citrus. Both strains come in at 20-26% THC. Strain lineage: GMO Cookies: Chemdog x GSC / Ultra Sour: MK Ultra x East Coast Sour Diesel.

About Ultra Sour

Ultra Sour is a sativa-leaning strain that comes from a cross of MK Ultra with ECSD. People who try it most often describe feeling uplifted, creative and energetic.

THC and potency

Public lab results give a good picture of its strength: 3 flower samples tested in 2021 came in at a median of 18.7% total THC (the middle half ranged from 14.4% to 18.8%). That is in line with most flower on Canadian shelves. Potency varies by grower and batch, so always check the label.

Aroma, flavour and terpenes

Its reported terpene profile is led by myrcene, with caryophyllene and limonene. Myrcene is known for earthy, musky notes with a ripe-fruit edge, while caryophyllene adds black pepper and warm spice. Consumers most often describe the flavour as lemon, lime and diesel.

Reported effects

Beyond feeling uplifted, reviewers also mention feeling happy and talkative. Some consumers say they reach for it when dealing with depression, stress and fatigue. The side effects mentioned most are anxiety, dizziness and dry eyes. These are personal reports, not medical advice.
