Organic Pro-Mix is the most consistent seed starting mix for growing your own vegetable, flower or herb transplants. Pro-Mix contains a lightweight mixture of the best ingredients that promote exceptional root development. Unlike other “potting mixes”, Pro-Mix is very fine which allows the plant roots to form a solid root ball for easy transplanting. The formation of a quality root ball will help to reduce transplant shock, leading to healthier and more productive plants. And because Pro-Mix is sterile, it reduces the amount of bacterial or fungal diseases that could develop during the transplant-growing timeline. Pro-Mix is also OMRI listed for organic vegetable production.
The peat moss and coir components provide excellent water retention, minimizing repeated water applications. The white stones of perlite ensure proper root ball drainage and increased air circulation around roots. Pro-Mix also includes a component called MycoActive, which promotes mycorrhizal associations. Mycorrhizae are a symbiotic relationship between plant roots and beneficial fungi. In this relationship that is beneficial to both the fungi and the plant, the fungi increase the absorption ability of the plant roots, while the plant roots provide food (glucose) to the fungi.
Each bag of Pro-Mix Organic Seed Starting Mix contains 16 quarts, which is sufficient for starting two of our 162-cell, heavy duty seed starting trays. That’s enough to grow 324 transplants! This mix works great for growing nightshades like tomatoes, peppers and eggplant. They also work great for brassicas like broccoli, kale, cauliflower, cabbage and kohlrabi. You can even use it for growing flower transplants of zinnias, sunflowers and celosia (cockscomb)!
