Sprout.

The smarter way to start your seeds.

Sprout. is a single-pod germination skin designed to work with Heat Pack. Together they create a controlled, heated environment for reliable seed germination.

Made entirely from high-quality EU food-grade silicone, Sprout. fits over Heat Pack. like a protective skin, forming the complete germination device. The skin shapes the warmth from Heat Pack. into a stable space where seeds can hydrate, sprout, and develop strong taproots.

Sprout. is designed for growers who want precise temperature control and a dedicated germination environment.

Why Sprout. Exists

Seeds germinate best when warmth, moisture, and airflow remain balanced.

Sprout. was designed to transform Heat Pack. into a complete germination device by creating a protected environment around the seed while allowing gentle passive airflow.

This combination helps maintain stable conditions while allowing growers to easily monitor and transplant seedlings at the right moment.

Key Benefits

• Single-pod heated germination device

• Made from EU food-grade silicone

• Signature airflow grooves for passive ventilation

• Magnetic silicone lid for secure closure

• Designed to work with Heat Pack.

How Sprout. Works

Sprout. fits directly over Heat Pack., forming the body of the germination device.

The silicone skin captures the stable warmth produced by Heat Pack. while the airflow grooves allow gentle air exchange around the germinating seed.

The magnetic lid keeps the pod closed while allowing easy inspection during germination. Once the seed has sprouted and the taproot appears, the seedling can be transplanted into your preferred growing medium.
