Our Root Starter is assembled and quality-checked in France.

Each kit is built to provide a clean, stable, ultra-humid environment—ideal for waking up bulbs and seeds safely.

What is the Root Starter?

The Root Starter is a transparent pot designed to create a microclimate of over 90% humidity, while keeping the bulb out of direct water contact.

What’s inside:
• 1 transparent pot
• horticultural biochar (activated charcoal)
• 1 protective grid
• labels to identify the bulbs/seeds inside

How to use it (simple & highly effective):
1) Place your bulb (or seeds) on the grid.
2) Fill with water right up to the grid level so the biochar becomes fully hydrated.
3) Important: the bulb should never sit in direct contact with water.

Why it works:
Biochar helps reduce—often prevent—rot by keeping the environment more stable and “clean.” The pot’s structure maintains very high humidity, ideal to restart cellular activity without drowning the bulb.

Optimal temperature: 25–30°C
In this range, dormancy breaks more easily: abscisic acid (ABA) (the hormone that maintains dormancy and makes growth “risky”/limited) decreases, encouraging cytokinin activation—hormones linked to cellular wake-up and renewed growth.
