If you love the sound of Runtz so far, then wait until you hear this: it possesses an exceptional resistance to common diseases and pests. As a result, it’s a popular strain to grow because it needs less care than some other strains. Despite being a balanced hybrid, Runtz grows like a sativa in the latter stages. You will need to train the plants to get the best yield, ensuring that it grows outward instead of straight upward. The Sea of Green (SoG) method works great with Runtz.
Runtz can grow very fast and provide high yields if you give it the right care. Lots of cultivators nourish this strain with nitrogen supplements, but be careful to avoid nutrient burn. Indoors,Runtz flowers in around 7-9 weeks and yields approximately 14-16oz per square meter. However, this strain loves space, so growing outside is preferable. In the Northern hemisphere, it will flower around mid-October and can yield up to 18 ounces per plant.
