Where does Blackberry Runtz come from?

Blackberry Runtz is credited to Purple Caper Seeds in California. Two listings agree on the cross: Runtz Cake, a sweet dessert strain from the Runtz family, and Blackberry Kush, a dark-fruited indica.

It's usually described as an indica-leaning hybrid, roughly 60% indica. The longer name, Blackberry Runtz Cake, points back to its cake parent, and both names refer to the same strain.

What does Blackberry Runtz smell and taste like?

Expect sweet and fruity first, with candy and cream on top and a ripe blackberry note running through it. Underneath there's an earthy side, and one listing also picks up a faint cheesy edge.

Myrcene is the only terpene published as dominant for it so far. Myrcene is often linked to an earthy, musky smell, which fits the darker notes under the candy.

Blackberry Runtz effects: what people report

People most often describe Blackberry Runtz as relaxed, with a mostly calming feel overall. Some reviewers mention a euphoric, uplifted or even talkative start, while others say it gets sleepy as it goes on.

These are reports, not promises. How it lands depends on the batch, how much you have and your tolerance. Dry eyes and dizziness are the downsides people mention.

How strong is Blackberry Runtz?

Published numbers are thin. The listing that gives a figure puts Blackberry Runtz around 22% THC, which is moderate to high, with very little CBD.

Because there isn't much data, go by the label on your product. If it's new to you, start small and give it time before having more.

Buying Blackberry Runtz in Canada

Look for either name, Blackberry Runtz or Blackberry Runtz Cake. Runtz is a big family, so check that the product describes the Runtz Cake and Blackberry Kush cross rather than another Runtz with berry in the name.

If you find it, check the THC and CBD numbers and the packaging date on the label, since fresher flower keeps more of the berry smell.

Blackberry Runtz vs Blackberry Kush

Blackberry Kush is one of Blackberry Runtz's parents and the source of its dark fruit. Blackberry Kush is the earthier, heavier of the two, with berry over a hashy Kush base. Blackberry Runtz adds sweet candy and cream from its Runtz Cake side, and reports describe it as a little more upbeat at the start before it settles. If you want classic berry Kush, go with Blackberry Kush. If you'd like the berry with dessert sweetness, try Blackberry Runtz.
