Amnesia Haze has been on a meteoric rise to the top since she burst onto the mainstream scene in 2004 with her first High Times Best Sativa Cup win. She did the double in 2012, scooping yet another HTCC first prize. Critically acclaimed and beloved by sativa sybarites everywhere, Amnesia Haze is an exotic cannabis cocktail of Jamaican and S.E. Asian genetics. Don’t expect a flurry of creativity, rather a trippy, cerebral ride. Light up and lift off, literally. Just a few tokes of this tropical citric brain fog will put your head in the clouds.

In the grow-op or outdoors in warm Mediterranean climates, Amnesia Haze is a space-hungry, jolly green giant. Early training and pruning is highly recommended to focus her vigorous growth and control stretching. Some hands-on attention and healthy doses of fertilisers during her 12-week bloom cycle can pay an enormously dank dividend come harvest. Huge, long-running colas covered in orange/red hairs packing 20%+ THC levels will convert you to a regular first class Amnesia Haze flier.

Royal Moby is our sativa-dominant leviathan. This strain is a weed white whale. No other sativa-leaning hybrid can match her awesome stats. Fat, frosty colas and beastly buds on side branches make Royal Moby our heavyweight champion head stash. The breeders at RQS have refined this Spanish classic and fine-tuned her for maximum potency and production. Indoors or outdoors in southern climates, huge individual plants in large containers can deliver scale-tipping harvests.

Although she is a real space-filler both laterally and vertically, she is very friendly to beginner growers. Royal Moby is quite tolerant of high doses of nutrients, and is a proven performer in all kinds of substrates and grow setups from organics to aeroponics. 9-10 weeks of bloom and gargantuan, gooey buds that could pass for indica such is their density will be ready for harvest. Outdoor farmers will be felling ganja trees mid-October. A mix of earthy and citrus aromas and a sweet, fruity flavour with 20%+ THC levels makes you want to pursue this monster.

Chocolate Haze is brain candy. This tasty cannabis strain is the product of successfully hybridising OG Chocolate Thai and Cannalope Haze genetics.Chocolate Haze is truly a combination of ‘80s classics that will take you back to the days when getting high was all about touching the sky. Musky, coffee, and slightly fruit-scented buds have major bag appeal for a near-pure sativa strain. The mix of sweet chocolate and melon flavours will tempt you to overindulge.

Take care to keep relative humidity low in the grow-op and harvest before the autumn rain to prevent mould from spoiling this rare dessert dankness. Tall plants with large internodal spacing are to be expected. Treat her right with low-medium doses of fertilisers and make sure she receives plenty of light during her 9-10 week bloom cycle. If all goes according to plan, a fat stash of up to 25% THC Chocolate Haze can be yours.

Royal Highness is the queen of whole plant medicine. The CBD-rich cannabis market is dominated by indica genetics. Royal Highness brings trademark sativa qualities into the mix with genuine daytime energy and uplift. This next-generation, high-CBD hybrid was engineered by crossing two renowned medical strains, Respect and Dancehall. Royal Highness delivers a clear, calming high without lethargy that makes for the perfect daytime smoke for medical users.

Princess Leia has got nothing on our girl. Royal Highness is a badass sativa queen that can hang with the toughest of rebel hybrids and seduce both medicinal and recreational cannabis growers. Her compact structure and short bloom cycle of just 8-9 weeks makes her something of a sativa in disguise with a more indica growth pattern. But make no mistake, her zesty, skunky nugs won’t weigh you down with a heavy psychoactive high; although, harvests can be pretty hefty with minimal grower.
