Our Antler Reishi grow kit is a 5 lb block fully colonized with first-generation Ganoderma multipileum. Instead of a flat shelf, it grows upright, branching, antler-shaped columns, and it gets there by keeping air exchange low, which is the opposite of what oyster kits want. Harvested antlers are dried and simmered for tea rather than cooked.
Tall, branching, horn-like columns that look nothing like the flat Reishi most people picture.
Low air exchange is the goal, so there's no fanning and very little fuss. Mist and wait.
Woody and bitter rather than tender. Dry the antlers, slice them and simmer them for tea or tincture.
The hard parts (sterilization, inoculation and colonization) are done before the block ships. Antler Reishi has one rule that's backwards from most kits: keep fresh air low, because trapped CO2 is what drives the antler shape.
Cut a single slit across the face of the block as shown in the instructions. One slit is all it needs; don't open the bag further.
Lightly mist the cut face once or twice a day with the included mister. Keep it from drying out; don't soak it.
Give it 8–10 hours of indirect light a day and keep it out of drafts. Don't fan it the way you would an oyster kit.
Cut the antlers free once they've fully developed. Then stop misting for about a week to let the block rest before the next flush.
Less fresh air, more antlers: the branching form develops under elevated CO2. More ventilation pushes the growth toward a flatter conk, so resist the urge to open the bag or fan the block.
Get more from your kitA Tabletop Humidity Tent, kept closed or lightly vented, holds both humidity and CO2 around the block, which is exactly what the antler form wants. Ready to grow Antler Reishi from scratch? Start with our Antler Reishi liquid culture syringe.
Reishi is slower than oyster or Lion's Mane kits. Expect the first antler-like growths over several weeks rather than days. Keep misting on schedule and be patient.
No. Do the opposite of what you'd do for an oyster kit. Low air exchange and elevated CO2 are what produce the antler form; more fresh air pushes it toward a flat conk and doesn't make it faster.
Most blocks give multiple flushes totaling 1.5–2 lb wet weight. After each harvest, pause misting for about a week to let the block rebuild, then resume.
Most growers dry it thoroughly, slice it thin and simmer it for tea or make a tincture. The texture is woody and the flavor earthy and bitter, so it isn't cooked and eaten like a gourmet mushroom.
Indoors is strongly preferred. The block needs steady temperatures and protection from wind, direct sun and insects; fungus gnats find an exposed block quickly. A kitchen counter, bathroom shelf or any spot out of direct sunlight works well.
The kit is already colonized and ready to fruit, so there's no sterile work. Our Antler Reishi liquid culture syringe is for growers who make their own grain spawn and want to scale up or run multiple grows.
Sold as a mushroom growing kit for cultivation. Antler Reishi is the subject of ongoing scientific research, but nothing on this page is intended to diagnose, treat, cure or prevent any disease.
I didnt realize how massive the block would be. Arrived ready to fruit, so now just playing the waiting game.
This was my first time growing Antler Reishi and I was very impressed with the results. Such a cool mushroom with amazing colors
Arrived on time. Perfect condition. Simple instructions. Love these kits! Excited to enjoy some reishi tea soon :)
Minimal effort required~ ~ I just placed the bag in a window and about 2 months I have some really crazy looking antlers growing about 6" now on all sides! Very slow but entertaining and a cool bag to display for friends!
