Sterile Lab Skills: Agar and Liquid Culture

Who this is for

This course suits growers who can already fruit a block and want to control their own genetics. It focuses on the lab skills that keep strains clean and strong.

What you will learn

You will learn to pour and work on agar, make and maintain liquid culture, isolate a single healthy strain, and recognise contamination early. These skills let you multiply cultures cheaply and keep them pure over time.

What you need

Agar plates, a scalpel and flame, liquid culture jars, and a still air box or flow hood. Careful, patient technique matters more than expensive equipment.
