Emerald Jack

Sativa dominant Emerald Jack is a cross between Emerald OG and the highly respected Jack Herer strain, which is named after the famous American cannabis activist who died in 2010.

The Emerald Jack strain has a pungent aroma that includes notes of freshly turned earth and spice. The flavor is quite complex with competing hints of sour fruit, exotic spices and citrus. The high comes on gradually but when it does you’ll feel euphoric, energised and creative. The stimulant qualities of this weed make it a good daytime smoke. Medically, it can help with stress and poor appetite.

The result of an Emerald Jack grow is a tall, gangling plant, reaching as high as three metres. The leaves are long-fingered and pale green while the buds are cone-shaped and covered in orange hairs and resinous crystals. THC levels are in the 15 to 20 percent range.

Indoors, Emerald Jack plants need trimming to keep them in bounds. This is a hungry plant and it will appreciate a good amount of nutrients, although it’s equally happy in soil or hydro. Flowering time is nine to 10 weeks and you can expect to harvest between 500 and 750 grams per square metre.

Outdoors, the Emerald Jack strain needs a climate at least as warm as the Mediterranean to thrive. As it grows, it will need staking and it’s best to plant it in a sheltered spot to avoid wind damage. Outdoor harvest in the northern hemisphere is in mid-October

Emerald Jack appeals to fans of the euphoric, soaring high that Sativa strains offer. It’s not too hard to grow, yields are high and the flavor is packed with fruit and spice.
