Sleestack is bushy with branches. She does not grow tall like the Shrom mother and also doesn’t take as long as Shrom to finish. These short stout plants pack on weight after the fifth week, increasing by about 2 1/2 times the size they were at forcing by the end of 9 weeks of flowering. The plants are averse to extreme heat and will space a lot if the beginning phases of growth or flowering are too hot. However, beyond the heat sensitivity, Sleestack is an agreeable plant that the novice can grow. She bounces back from nutrient mistakes, is not prone to mold, and has proven very resistant to powdery mildew even when surrounding strains become infested.

At maturity, Sleestack is a relatively non-smelly classically shaped plant with thick, sharply serrated leaves and frosty medium-dense nuggets that are dark under their considerable bling. For the Sleestack, it is about hoarding crystals. These buds stack crystals upon crystals, becoming gaudy with frosty resin. This strain offers an unexpected, exotic smoke with medicinal value. The fuel-haze flavors carry through, leaving a pleasant taste that lingers. The high is clear headed with a slow rising onset that can become energetic and mildly psychedelic. The secret to this plant is the dry-sift kief, which is amazing and great for concentrates, especially if the concentrate doesn’t require any water processing that may dull the great flavors. Kief fans or those who make any medical products from kief such as tinctures or other concentrates should consider adding this plant to the garden. Sleestack won 3rd place in the 2009 Spannabis Champions Cup in the outdoor category.
