Article number: GMSM3CF4
Availability: In stock

A premium mix for indoor growing, Sunshine® Mix #4 with Mycorrhizae contains a higher amount of horticultural perlite for plants that prefer greater air porosity. Its our classic #4 boosted with endomycorrhizae and containing Resilience™ for stronger stems and improved root mass. Low phosphorus fertilizer has been included to better support mycorrhizae establishment and growth.


All SSA mixes are myco-active, so you can grow in confidence. Each contains a proprietary blend of endomycorrhizae designed to colonize a wide spectrum of crops. We are proud of these blends, and the great results they give growers and gardeners every day.

Other mycorrhizae-enhanced growing mixes on the market may contain a single species of endomycorrhizae or a blend of endo and ecto mycorrhizae. Sun Gro’s are better. We amend ours with a blend of endomycorrhizae species designed to enhance colonization under a wide range of growing conditions. And, we do not add ectomycorrhizae because they provide no benefit to most crops.

What are the benefits of Resilience-enhanced mixes?

Time and time again, research at Universities, in commercial grower trials and at the Sun Gro Discovery Center, supports significant and dramatic positive results with Resilience. Trials have shown that plants grown in silicon-enriched mixes have the following advantages:

40% BETTER ROOT GROWTH for increased nutrient uptake and support

13% EARLIER FLOWERING for more attractive plants, faster

 12% INCREASED STEM DIAMETER for stronger plants and reduced breakage

77% LONGER TIME BEFORE WILT for increased shelf life
