About Grandaddy Haze
Crossing Granddaddy Purple with Haze is an unusual pairing on paper - one known for deep purple hues and heavy structure, the other for towering height and long flowering - and Connoisseur Genetics landed on an 80 percent sativa-dominant result from that combination. THC comes in between 17 and 19.7 percent, respectably strong without topping the charts. True to its Haze half, this one takes its time in flower, running 9 to 11 weeks before harvest, and Connoisseur rates the grow difficulty as moderate rather than beginner-friendly. Indoors it stretches to 100 to 150 centimeters and can produce 400 to 500 grams per square meter, numbers that suggest growers should plan for height management if working in a tight tent. The cross itself, the extended flowering window and the generous yield are what carry this cultivar's documented profile.
