Sunshine Mix® #4 with RESiLIENCE® (RSi) from Sun Gro® Horticulture is a reliable and time-tested blend that includes the benefits of mycorrhizae and silica. Sunshine Mix #4 has been a cornerstone in professional growing for decades, and this enhanced version is designed for situations where high air capacity and fast drainage are essential. It is particularly recommended for crops that are frequently watered, salt-sensitive, or require regular leaching.
Contains dolomitic limestone to adjust media pH to 5.0-7.0 and to provide calcium, magnesium and silica. Gypsum is added as a source of sulfur and calcium. In addition, Sunshine Mix #4 has a highly soluble nutrient charge equivalent to about one liquid feeding with a complete fertilizer, plus trace elements at a normal rate.
Ingredients: Canadian sphagnum peat moss, coarse grade perlite, gypsum, dolomitic lime and Sun Gro's long-lasting wetting agent.
Growers Tip: avoid compressing the mix when filling containers or when planting to preserve desirable air porosity.
