Nos pains de substrat pour nameko (Pholiota nameko) sont issus d'une souche populaire largement cultivée au Japon. Ces kits produisent des champignons au goût terreux avec de subtiles notes fruitées. Et, une fois cuits, ils rempliront l'air d'un arôme rappelant la noix de cajou et le caramel écossais. En poussant, les nameko se couvrent d'une couche de gélatine naturelle qui leur donne un aspect unique, presque brillant. En plus de consommer le champignon, leur revêtement gélatineux a diverses utilisations et peut être transformé en soupes, en sauces ou utilisé comme agent épaississant naturel !

Les kits de champignons nameko demandent une attention particulière et plus de temps pour produire des champignons. Comme ils nécessitent des températures plus fraîches et une humidité constante lors de la fructification, ils sont plus difficiles à cultiver. Ils ne sont pas idéaux pour les débutants, mais peuvent être très gratifiants pour les cultivateurs expérimentés. L'utilisation d'une tente à humidité ou d'une chambre de fructification à humidité contrôlée aidera à atténuer les problèmes d'humidité tant qu'il y a un échange gazeux adéquat.

Receiving and Storage

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!

Fruiting blocks should be used within 1 week of receipt. If you don't plan to use immediately, you can refrigerate your block for up to 6 months.

Growing Instructions

For the majority of mushroom species, all that is needed to initiate fruiting (or begin the growth cycle) is a change in environmental conditions -- specifically humidity, light, temperature, and changes to oxygen and CO2 levels.

For best results:

We recommend growing your nameko block in a fruiting chamber (like a monotub or martha tent) as a controlled environment will decrease the risk of contamination and increase the chances of success. 

Creating optimal conditions:

The environmental parameters for nameko mushrooms can be found on this page under "Temp, Humidity & CO2 guide" and on page 15 of our fruiting block instruction booklet.

How to initiate fruiting:

  • Cut off the top of the bag, leaving plastic bag sidewalls approximately 4” taller than the block.
  • Using a clean fork, scratch several 1cm deep cuts into the mycelium coating. Don't cut too deeply, as this will result in the mycelia fracturing easily.
  • Place back into the fruiting chamber until ready to harvest.

Pro tips:

  • Namekos like it cold, below 65°F, throughout pinning and fruiting. If you try to grow at warmer temperatures, you will get small underdeveloped fruiting bodies. To get temps down in your fruiting chamber, fill the bottom of a small, insulated, uncovered box with ice cubes and sit the nameko fruiting block on top. Then place the box back into the fruiting chamber. Replace ice cubes daily.
  • Namekos need high humidity during the pinning phase. To get the high humidity required without creating water accumulation in your fruiting chamber, use a spray bottle twice a day to supplement fruiting chamber humidity. By doing this, you won't have to run the humidifier as high.

Special considerations:

  • Nameko are sensitive to moisture loss. Be sure the surface is always kept moist or the primordia (pins) will be at risk of aborting.
  • Nameko are sensitive to CO2, especially in the pinning phase.

Harvesting your mushrooms:

Harvest namekos before the caps open. Remove entire cluster with care to minimize breaking and then trim away the substrate.

Growing different blocks together:

With some compromise, many different species of mushrooms can be grown together in a fruiting chamber. First, consider the temperature range of the mushrooms you desire to grow, and second, the CO2 sensitivity. Humidity ranges overlap for the majority of species. We encourage you to experiment with many different groupings!

Troubleshooting:

Having issues with unusual growth, stunted growth, or no growth at all? Refer to pages 16-18 in our fruiting block instruction booklet.

Temp, Humidity, & C02 Guide

Temperature 45-65°F  |  7-18°C
Humidity (Phase 1: Primordia)98-100%
Humidity (Phase 2: Fruitbody)88-95%
CO2 Sensitivity (Phase 1: Primordia)500-1,000 ppm
CO2 Sensitivity (Phase 2: Fruitbody)<1,000 ppm

  • Primordia -  The earliest recognizable stage of fruitbody development. Also known as “baby mushrooms” or “mushroom pins.”
  • Fruitbody - A fully grown mushroom, the reproductive structure of the organism in which the spores are produced.
  • 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.

Nameko mushroom kits require extra attention and more time to produce mushrooms. Because they need cooler temperatures and constant humidity when fruiting, they are more difficult to cultivate. They are not ideal for beginners, but can be quite rewarding for experienced growers. Using a humidity tent or humidity-controlled fruiting chamber will help mitigate moisture issues as long as there is proper gas exchange.

Frequently Asked Questions

Fruiting block kits are mushroom grow kits, but tend to be larger (5 lbs) and some require a bit more care depending on species. Instead of boxes, they are bagged. We recommend growing them in a fruiting chamber such as a monotub or martha tent set up like our BoomRoom. A controlled environment will produce the best results for the fruiting blocks. And, since these kits are slightly larger, they can produce more mushrooms than our Spray & Grow Kits.

Oyster mushrooms and lion's mane mushroom fruiting block kits are great for beginners because they are reliable producers and require the least amount of effort. Reishi is also great because the mushroom grows in the unopened bag (no special care or fruiting chamber required!)

All kits should grow a minimum of one flush of mushrooms, but with a little patience and skill you can often get a second or third flush depending on the species! After you’ve harvested your first flush of mushrooms, remove any growth from the block and follow these instructions:

⮕ If you have a martha tent or an automated fruiting chamber, leave the humidity and fan running and wait about 2 weeks for new pins to begin forming.

⮕ If you are using a monotub or non-autmated fruiting chamber, open 2x daily and spray blocks generously with water. Try not to expose the blocks for too long to decrease chances of contamination.

⮕ If you don't have a monotub, martha tent, or fruiting chamber cover the block with a humidity tent made from a large plastic grocery bag with LOTS of small, quarter-sized holes. Remove the humidity tent 2x daily and spray blocks generously with water.

Be patient: It's totally normal for it to take longer for mushrooms to appear with each subsequent fruiting. However, if there's no progress after two weeks, it’s a good idea to soak your block.

Soaking your block: Take your block out of the bag and soak in a bowl of cool water. Most species only need to soak for 20 minutes. However, only soak your lion's mane block for 5-10 minutes as these blocks tend to break apart if soaked for too long. After soaking, let the block drain by leaving it cut side down for another 10 minutes or tip it around to let extra water run off. You don't want to leave standing water in your bag, so pat your block dry with a towel before placing it back in the bag.

Note: Shiitake blocks should not be placed back in the bag.

For most species, you should leave the block in the bag for the entire duration of the growing cycle. However, there are some exceptions.

⮕ Shiitake should be removed from the bag before going into the fruiting chamber.

⮕ Nameko should have most of the top of the bag cut off (leaving about 4" of plastic above the block) before going into the fruiting chamber.

Our fruiting block kits are made fromsawdust blocks that have been ammended with substrate supplements.
