Red reishi (Ganoderma lucidum) is an edible medicinal mushroom known as “Ling Zhi” in China and “Reishi" or "Manetake” in Japan. Our reishi mushroom kits are one of the easiest of all of our fruiting block kits, as they are very reliable producers and require next to no upkeep. That's because they can live their entire life-cycle within their unopened bag.
Reishi take their time and grow very slowly. Depending on your needs, you can harvest your kit early when the mushrooms resemble antlers and are only a few inches tall. Or, you can 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.
Or, click “Instructions” below for a digital step-by-step guide.
1) Your Reishi grow kit is an amended sawdust block that has been completely colonized by mycelium. Reishi mushroom is one of the easier species to grow indoors as you simply allow the block to produce the mushrooms inside the bag. REMEMBER: DO NOT OPEN THE BAG!
2) Keep your Reishi kit out of direct sunlight in an area that is between 55 and 70 degrees Fahrenheit. Mushroom pinsets (baby mushrooms) will begin to form within the first month or two of purchasing the kit. The inside of the bag is like a terrarium that will provide the mushroom proper air exchange and humidity. This kit needs ambient light to grow properly. Make sure you don’t put the kit someplace where there isn’t any ambient light.
3) Reishi grows extremely slow. At first, your block will produce small white "nubs" that grow into thin, multi-colored antlers. As the antlers hit the top of the bag, they will start to twirl back around themselves which can create other-worldly mushroom sculptures. (We’ve allowed our own blocks to grow for more than six months in some instances with dramatic results!)
If you want your reishi to form a mature mushroom cap instead of antlers, cut off the entire top of the bag just under the seal when the antlers are 3-6˝ tall. You will need to increase overhead lighting and maintain humidity by misting the blocks daily, or moving them to a humid location. Note that cap formation can be challenging, especially for first-time growers. Adequate light, humidity, and air flow must be in perfect balance, and the exposed reishi block is susceptible to drying out and/or becoming moldy if not well supervised.
4) When you decide to harvest your Reishi, simply remove the bag and cut the individual antlers off the sawdust block. Reishi is a bitter and woody medicinal mushroom. You may dehydrate and use the antlers in tea, or create tinctures from them by macerating and steeping them in 100 proof alcohol for a month or more (directions for double-extract tincture making can be easily found online!) Alternatively, you may choose to keep your Reishi antlers on the sawdust block and allow the whole kit to dry out. You can then use your Reishi kit as a table centerpiece or natural sculpture! Just remove the plastic bag and keep the kit someplace warm and dry for 2-3 weeks.
Fruiting temps 65-80 degrees F Humidity 85-95% CO2 Sensitivity <20,000 ppm (antler); <2,000 (fruitbody)
- Fruiting - The phase of growth in which visible mushrooms begin to appear.
- CO2 sensitivity - When CO2 levels are too high, yields will decrease, stems will become long and stringy, caps will be small, and/or growth will halt.
If you don't plan to use your reishi kit immediately, store in the refrigerator for up to 6 months. If left at room temperature, it will continue to grow.
Reishi mushrooms are intensely bitter and woody and usually aren't considered culinary unless harvested very young. However, we do recommend throwing a slice or two of dried reishi into soup stock, much like you'd use a bay leaf, to infuse the broth with its medicinal properties. You may also choose to incorporate reishi into medicinal teas tinctures.
If you’re going to consume home-grown mushrooms, make sure to cook your fresh mushrooms thoroughly with heat. If it is your first time eating this species, it is best to start with a small amount to check for allergies, even if cooked.
Mushrooms grow spores as they develop. This is a natural means of reproduction. This is when people with allergies or compromised immune systems may want to consider putting fruiting mushroom kits outdoors or in a well-ventilated area. Spores in mushrooms sometimes cause respiratory irritation. In rare cases, spores may also cause irritation for some non-allergic or non-immunocompromised mushroom growers. If you are one of them, it is recommended to reduce the overall spore load by harvesting mushrooms while they are still in their younger growth stages.

I had the best time growing these reishi mushrooms. The fruiting block instructions were comprehensive, the care was easily done, and the results were great! I let these grow for a full year, watching them hit the top of the bag and start to go back down again. It was super interesting to watch the growth patterns. I harvested the mushrooms and cut them apart to see what was inside. The rest I dehydrated with some chamomile and rose petals for a lovely homemade tea :)
A whole year! We love your dedication and that tea sounds like a wonderful elixir.
Easy to grow
This is my second reishi grow kit. Talk about hands off. I leave it near my heater and in indirect light and it grows. The only downside is that it takes about 6 months but it's a really fun process seeing how it changes!
So excited about my reishi mushrooms!
I am so excited to see the final growth of my reishi kit in a year! I have only had it one month and it is already starting to sprout some little white antler tips. North spore always has amazing fungi products. I have purchased and grown their Lion's mane kit before and was amazed at how easy and rewarding it is to grow and eat.
