Tips for Growing Critical Runtz

When it comes to growing Critical Runtz, there are a few things we’ve noticed that can make your cultivation experience even better.

This strain is a robust and resilient plant, showing great resistance to pests and common diseases.

That means it’s forgiving, even for growers who might not have years of experience under their belt.

However, to really see it shine, this strain thrives best in warm, temperate climates with occasional rainfall, similar to Mediterranean conditions.

If you’re growing indoors, controlling the temperature to stay between 20–28°C (68–82°F) will help this strain flourish.

As for difficulty, we’d say it sits comfortably at an intermediate level.

While its resilience makes it suitable for beginners, maximizing its XXL yields might require some extra attention to training techniques like SCROG or Lollipopping.

One thing that really stands out to us is how quickly it grows vertically, while still maintaining a dense and manageable structure.

That combination of height and sturdiness is rare, and it’s something we absolutely love about Critical Runtz!
