FRIENDS. FUN. LEGENDARY CANNABIS.

THREE THINGS THAT MAKE OUR WORLD GO ROUND, AND ROUND.

Each better together, always and forever. Spinach® is here for all the fun that only happens with friends. Where we grow closer by the experiences we share, and the moments made a little more epic whenever there’s legendary cannabis to go around.

Spinach

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

<p>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;</p>
