Sprout by Seed Starter + Heat Pack Seed Germination Kit

A Precision Kit for Faster, More Reliable Germination

Paper towels dry out. Plastic bags trap stagnant air. Heat mats warm a wide area at a fixed, imprecise temperature. Most seed germination methods rely on conditions you can't actually control.

The Sprout. + Heat Pack. Kit is built differently. Heat Pack. delivers adjustable, targeted warmth from 20°C to 35°C in 1°C increments. Sprout.'s EU food-grade silicone insulates that warmth into a sealed chamber, with airflow grooves that maintain oxygen exchange and a magnetic lid for easy inspection.

The result is a stable, repeatable microenvironment — the kind serious growers have always needed and home growers rarely had access to.

What's in the Kit

• 1 × Sprout. silicone germination pod (your choice of Black Lid or Orange Lid, both with Black Body)
• 1 × Heat Pack. USB-C powered thermal heater (20–35°C adjustable)
• 1 × USB-C cable
• 1 × Allen key (for temperature adjustment) — pending supplier confirmation
• Instruction manuals

You'll also need: a USB-C wall adapter (5V minimum 1.5A; 20W or higher recommended). Most modern phone chargers work.

How It Works

1. Slide the Sprout. silicone skin over Heat Pack.
2. Plug Heat Pack. into a USB-C adapter
3. Set your target temperature (Allen key supplied)
4. Place your seed inside the pod with your chosen germination medium
5. Close the magnetic lid — airflow grooves vent gently while the chamber holds heat and moisture
6. Lift the lid to inspect; the magnetic seal makes it effortless
7. Once the taproot emerges, transplant into your preferred growing medium

Heat Pack. remembers the last temperature setting and resumes automatically when powered on.
