Choosing Growing Media
What is a soilless growing mix?
A soilless growing mix is a carefully engineered substrate designed to promote healthy root development through balanced aeration, drainage and water-holding capacity.
Sun Gro mixes are developed by horticultural experts and manufactured under strict quality controls to support predictable, repeatable results in commercial production systems.
How do I choose the right growing media for my operation?
Start by matching the mix to your crop type, container size and production stage, whether propagation, general production or bark-based cultivation.
Sun Gro Grower Specialists can recommend best-fit solutions based on your operational goals, irrigation systems, environmental conditions and performance requirements.
Can Sun Gro create a custom blend?
Yes. Sun Gro develops custom growing media blends tailored to specific crops, production systems and regional conditions.
We also support growers who prefer to mix their own substrates using Canadian Sphagnum peat moss and other components. Our technical teams provide guidance to help optimize consistency and performance.
