Organic Red Reishi Mushroom Grain Spawn

Organic Red Reishi Mushroom Grain Spawn

Our USDA-certified organic red reishi (Ganoderma lucidum) grain spawn features a strain that produces beautiful, waxy, reddish-brown fruiting bodies that are highly prized for their medicinal properties. Due to its bitter flavor and tough texture, it is not recommended for culinary use. However, it is ideal for drying and making powders, teas, and stocks. It can also be extracted and made into a tincture. Reishi mushrooms will only produce one flush. If growing antlers, use large grow bags to allow enough space for tall antlers to form. For larger yields, allow the mushrooms to form conks instead of antlers. (This is done by allowing lots of fresh air exchange in the growing environment.) Recommended use: Reishi grain spawn can be used for indoor production using sawdust-based sterile substrate. Do not use grain spawn for log inoculation. This is not a mushroom grow kit. Reishi grain spawn must be combined with a substrate in order to fruit. Upon receiving your spawn: Remove it from the shipping box as soon as possible. Then, unfold the top of the bag, making room for air space. It's also important to check and confirm that the filter patch is not obstructed. This will help the organism breathe and continue to thrive! Scroll down for specifications, growing, and storage guides. reshi, lingzi, lingzhi, ling chih, bracket, bracket fungus, bracket fungi, ganoderma

Reishi

Reishi

Our reishi (Ganoderma lucidum) fruiting block features a strain that is widely cultivated in Asia. Reishi is an edible medicinal mushroom known as ā€œLing Zhiā€ in China and ā€œReishi" or "Manetakeā€ in Japan. Reishi mushrooms are one of theĀ easiest of all of our fruiting block kits, as they are very reliable producers and require next to no upkeep.Ā That's because they can live their entire life cycle within an unopened bag! Reishi take their time and grow very slowly. Depending on your needs, you canĀ harvest your kit early when the mushrooms resemble antlers andĀ are only a few inches tall. Or, you canĀ allow the mushrooms several more months in the bag to form more interesting growth patterns. You can also try for mature mushroom caps, which requires more supervision as well as opening the bag (which is described in the directions section below). This is a more challenging method, but can be very rewarding for those who have some prior experience with reishi kits. Upon receiving your kit: Remove kit from the shipping box as soon as possible. Then, unfold the top of the bag, making room for air space. It's also important to check and confirm that the filter patch is not obstructed. This will help the organism breathe and continue to thrive! ā®•Ā Click for printable instructions Alternate searches: antler reishi, reshi, lingzi, lingzhi, ling chih, bracket, bracket fungus, bracket fungi, ganoderma

Organic Red Reishi Mushroom Sawdust Spawn

Organic Red Reishi Mushroom Sawdust Spawn

Red reishi (Ganoderma lucidum) is an edible medicinal mushroom known as ā€œLing Zhiā€ in China and ā€œReishi" or "Manetakeā€ in Japan. It produces beautiful, reddish-brown, shelf-like fruiting bodies that are highly prized for their wellness properties. When fresh, the flat cap is soft and cork-like. Because it releases spores via pores, it lacks gills on its underside. And, depending on the age of the mushroom, the pores may appear brown, cream, or white. Because red reishi can be difficult to cultivate, it is recommended for advanced and enthusiast growers. However, it can be extremely rewarding for those who have had some success growing other mushrooms. Recommended use: Red reishi sawdust spawn is only recommended for use in log projects. One bag of sawdust spawn will reliably inoculate 20 logs. Red Reishi log chart: BEST WOOD SPECIES* Hard Maple, Sweetgum OTHER SUITABLE SPECIES Alder, Beech, Elm, Soft Maple, Mimosa, Mulberry, Oak, Peach, Sycamore, Willow AVOID Hemlock, Pine Upon receiving your spawn: Remove it from the shipping box as soon as possible. Then, unfold the top of the bag, making room for air space. It's also important to check and confirm that the filter patch is not obstructed. This will help the organism breathe and continue to thrive!

Shiitake mushrooms are a delicious edible fungus from East Asia and their flavor is described as rich, savory, buttery, and umami. This strain tends to produce generous flushes, making them a great mushroom for confident beginners and intermediate growers. Blue Oyster (Pleurotus ostreatus): Our blue oyster block is a fast substrate colonizer with a strong bluish-gray hue. It produces richly umami mushrooms with a soft, meaty texture that pairs well with most dishes. Oysters are very reliable producers and tend to yield large flushes of mushrooms. They are also one of the easiest blocks to get subsequent fruitings from and should reliably produce a second flush or more. Scroll down for tech specifications and instructions.
