Growing Tips & Our Take

Pineapple Slush XL Auto is a dream for growers of all levels, but there are a few tricks to get the most out of this tropical powerhouse.

Since it grows tall for an autoflower, providing some support to the branches can help prevent them from snapping under the weight of its dense, resin-coated buds.

It thrives in warm, sunny climates but can also handle cooler environments, making it a versatile option for both indoor and outdoor cultivation.

For the best results, keep temperatures between 20–26°C (68–79°F) and maintain a humidity level of 40–50% during flowering.

Despite its high resin production, it shows a strong resistance to pests and mold, making it a low-maintenance strain even for new growers.

Since it’s an autoflower, avoid heavy pruning or topping, as it has a limited vegetative phase and recovers slower than photoperiod strains.

Instead, using low-stress training (LST) can help maximize light exposure and increase overall yield.

What really stands out about this strain is its incredible resin production—each bud looks like it’s been dunked in sugar, making it a top-tier choice for extractions.

The mix of sativa energy and indica relaxation gives it a unique versatility, whether you're looking for a boost or a smooth comedown.
