Hi Suzanne –

Sunshine Mix 1 and Sunshine Mix 4 are very similar with both being used for the production of a wide variety of crops. However, SS4 has added aggregate for better drainage. It is recommended where high air capacity and fast drainage are needed: growing indoors, during winter months, with frequently watered or salt sensitive crops, or where frequent leaching is required.

Hope it helps!
