Side-by-side plant root comparison on mat labeled Black Bear vs Competitor showing denser white root mass in Black Bear
Last fall, I began trialing Sun Gro Black Bear while still using Sunshine Mix #15, a bark-based mix with perlite. I noticed improved consistency and stronger root development across crops. I’ve now switched 100% of greenhouse operations to Black Bear, and it has made a real difference in the uniformity and overall performance of the plants.
