RuntzSweet Gelato Auto®
Sweet, fruity, potent auto-flowering strain with very high THC and high yields.

Runtz XL Auto is a taller auto-flowering strain created by crossing Runtz with Sweet Gelato Auto. This is an sativa/indica hybrid with high yields as well as high THC production - all in a short life span.

Runtz XL Auto plants grow to between 60 - 120 cm. tall and take just 8 weeks from the first pair of leaves through to harvest. Indoors growers will harvest 400 - 550gr/m2 while those growing outdoors should obtain 50 - 175 gr./plant.

Rich in terpenes, Runtz XL Auto is intensely sweet and fruity and with very high levels of THC its effect is powerful yet well-balanced as befits its almost 50/50 sativa/indica genetics, mentally stimulating while being physically relaxing.
