Two West Coast sativas in one plant
Blue Dream is the blueberry-and-haze favourite of California gardens. Green Crack is known for its fast finish and its tangy, mango-and-citrus smell. Blue Crack sits between them: sweet berry on top, a sharp citrus tang behind it and an earthy, slightly skunky base that shows once the flowers are cured.
It is a sativa-dominant plant and looks it, with longer internodes than an indica, narrow leaflets and spear-shaped colas that build length rather than width.
Faster than it looks
Green Crack's quick bloom carries through. The label gives 7 to 9 weeks of flowering, short for a sativa-leaning cross, and that matters outdoors in Canada. A plant that begins flowering in early August can be cut in the last days of September in a warm year, before the October rain sets in.

How to grow Blue Crack
Sativa-dominant plants stretch hard after the flip, so switch to 12/12 earlier than you would with an indica: when the plant is roughly half the height you can allow. It ends up a medium 100 to 150 cm.
Train it early. Topping plus low-stress training spreads the long branches into an even canopy, and a screen holds the colas in place as they lengthen. Feed moderately; sativas show nutrient burn on their thin leaf tips first, which gives you an early warning.
Outdoors, pick the sunniest, most sheltered spot you have. With full sun and good soil, the label puts the yield around 450 g per plant.

Im in week 6 of flower and these guys are beautiful. Bud sites are frosty white with blue tint. Sweet smell. Buds are starting to plump up. They grew taller than expected. 5 foot high. Will leave another review after harvest
JASON MCNELLIS –
So after harvest and curing this bud is choice. Grew two plants and the buds were so different. One had light blueish green buds that were plump with a fruity taste and smell. The other had buds that were real dark green with a hint of blue with bright red hairs. Completely caked with resin. The longer they cure the better they smell and taste. This is my new go to bud.
