These figures are ranges, not promises. Flowering time, harvest date and yield vary depending on growing conditions: the grower, the method and the season's weather. "Mold resistant" means mold tolerant: less prone to mold and slower to be affected. No strain is 100% mold resistant. How we set these numbers →

About White Runtz
Genetics & strain profile
White Runtz is bred by Quebec Cannabis Seeds from Zkittlez and Gelato — the same two parents as Runtz itself, selected here for the white, frost-covered phenotype that gives the strain its name. It is a balanced hybrid with 25 to 29% THC, which puts its top end among the strongest strains in our catalogue, with heavy trichome production; low CBD, well under 1%, as a reviewer asked. It is one of our QCS Originals, carries our mould-tolerant badge, and we rate it moderately easy to grow, for new and experienced growers alike. It has three reviews so far, all five stars, from a grower who had just finished a run of our Black Runtz — “amazing to clone” — and was starting White Runtz next; he also found a polyploid seedling, a harmless oddity that turns up now and then in vigorous lines. We will add grower reports as they come in.
How White Runtz grows
Indoors it flowers in just 7 to 8 weeks with 450 to 500 g/m² — quick for a strain this potent — on a compact, well-branched frame that suits a tent and takes topping and a net well; the family clones easily, as our reviewer found with its sibling. The flowers get dense and heavily frosted, so keep humidity moderate and the air moving in the last three weeks, and feed moderately with calcium and magnesium under LED, since the Cookies side burns on heavy nutrients. Outdoors it is usually ready by late September to early October, which suits Canada and other northern climates, with up to 500 g per plant depending on growing conditions, and it is tolerant of common pests and mould, though no strain is immune. Cool nights late in flower bring out the purple under the frost.
Taste, aroma and effect
Sweet and fruity — the candy-bag fruit of Zkittlez — with a smooth, creamy finish from Gelato, and a soft gassy note underneath on some phenotypes. The effect starts in the head, uplifting and euphoric, and lifts mood and creativity before easing into a relaxed body, a late-afternoon or evening strain that at up to 29% THC is far too much for a newcomer; start small. For the rest of the family, see Runtz, Mint Runtz and Blackberry Runtz; for the Gelato side on an autoflower, Gelato Autoflower.

I found a polyploid in the white Runtz strain, is that usual?

The strain description neglects to mention the CBD percentage, I'm curious as to the levels.

Just finishing up a run with your other strain, Black Runtz, Amazing to clone., now I'm just starting a seedling of the White Runtz, I look forward to smoking it too.
