Sunshine Mix® #4 from Sun Gro® Horticulture is a reliable and time-tested blend. Sunshine Mix #4 has been a cornerstone in professional growing for decades, 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.
