Lambert offers hybrid off-white and old-fashioned brown Agarius strains in rye, millet, or synthetic inoculum. The hybrid off-whites perform well in a variety of conditions and are highly suited for fresh markets due to their excellent shelf-life. These strains produce high yields of excellent quality mushrooms when in the correct environment and handled properly. Our brown strains are more sensitive and less forgiving than the hybrid off-whites. Over-watering and sharp environmental changes should be avoided. Good harvesting techniques and pruning are vital for correct development, and if light is introduced the cap color will darken.
