We believe the world is ready to end a century of cannabis prohibition - a global movement rooted in Canada. Supreme has been at the centre of the cannabis space since 2014 in pursuit of this massive opportunity.

Supreme trades as FIRE (TSX.V:FIRE) on the Toronto Venture Exchange. FIRE is a testament to our passion for cannabis, our obsession with quality, and our mission to light up the cannabis sector.

We established 7ACRES as the first licensed producer focused on growing high-quality cannabis in high quantities. Today 7ACRES is en route to becoming Canada’s leading cultivator of consistently great commercial cannabis.

As legalization grows beyond our borders, we will continue to identify new opportunities to build innovative cannabis businesses across the globe.

SOUR CITRUS BOMB
220 – 280 mg/g THC
Boom go the terpenes! This next-level strain packs grapefruit flavours at near nuclear levels and delivers an over-the-top explosive aroma of sour-citrus. This exclusive cultivar is a cross of rocket fuel from Chemdawg and powered up potency of SFV OG Kush. Hard to find (and harder to pronounce) rare terpenes like valencene, camphene, guaiol and fenchol combine to take you on a sensorial ride of your life.

Atomic Sour Grapefruit 3.5g

Atomic Sour Grapefruit

Atomic by Bomb Seeds is a deep blend of potent genetics. <a href="/strains/og-kush">OG Kush</a> was crossed with <a href="/strains/chemdawg">Chemdawg</a>, which was then crossed with <a href="/strains/thc-bomb">THC Bomb</a> to create Atomic. This blend of THC-dominant genetics lends Atomic potency that isn&rsquo;t meant for everyone. Be warned that this intense high hits with a rush to the head and settles into a long-lasting body stone that evaporates stress and worries. Atomic has a fair yield and a Kushy flavor that is thick with gas and forest aromas. Enjoy Atomic after you clear your schedule as its effects may change your plans.&nbsp;
