Correspondingly, How many pounds of substrate do you need for a Monotub?

The substrate should be about three to five inches high in the tub. A 3-pound bag should be able to inoculate one or two moderately sized tubs.

Also asked, How much coir does a Monotub need?. Supplies Needed:

8 Quarts or 1 Brick of Coco Coir. 2 Quarts of Vermiculite. . 5 Quarts of Gypsum.

Besides, What is the ratio of spawn to substrate?

The more spawn used the faster the bulk substrate will colonize. Recommended spawn ratios are usually no less than 20% (1 part spawn to 4 parts substrate).

What is the best substrate for Psilocybe Cubensis?

The most suitable substrate for P. Cubensis is said to be rye grain. If grown inside a mason jar – a popular and effective method of cultivation – mycelium will permeate the grain within ten to fifteen days.

What is the best bulk substrate for Cubensis?


Manure is the aged, dried excrement of horses, cows, elephants, etc. It is one of the most effective bulk substrates for dung loving species like psilocybe cubensis, panaeolus cyanescens and agaricus bisporus (Portobello).

Does mycelium grow faster in the dark?

A commonly held belief among growers is that mycelium will grow faster in total darkness. There is no data to support this premise; however, significant exposure to direct UV light from the sun can be detrimental. ... Artificial or ambient light is sufficient light for the incubation period.

What does PF TEK stand for?

PF Tek stands for “psilocybe fanaticus technique”. It was first released in 1992 at Although the PF tek was originally developed in order to facilitate the cultivation of psilocybe cubensis it is also a great way for beginners to begin working with sterilised substrates and spawn production.

Do you have to case a Monotub?

STEP EIGHT – Casing, Fruiting & Harvesting your Monotub

Once you begin seeing the formation of primordia, you have the option to case your tub, which means covering the entirety of the substrate with a very thin layer of 100% coco coir. However, this step is completely optional.

What's the difference between vermiculite and perlite?

Vermiculite is a spongy material that is dark brown to golden brown in color. It is shaped like flakes when dry. Perlite is a porous pumice-like material that looks like white granules. Sometimes perlite is mistaken for tiny plastic foam balls when used in potting soil mixtures.

Is Coco coir sterile?

In most garden applications, you do not need to sterilize coco coir, although some gardeners will sterilize it to make seed-starting mix. For growing mushrooms, coco coir should always be sterilized before use. Coconut coir is naturally non-sterile and has fungal spores which are generally harmless to plants.

How do you make a Monotub Tek?

Monotub Tek Overview
  1. Make or purchase grains for spawn.
  2. Inoculate the grains with Spores.
  3. Break up and mix grains when 20-30% colonized.
  4. Allow mycelium to fully colonize grains.
  5. Build Monotub.
  6. Prepare bulk substrate.
  7. Inoculate bulk substrate with fully colonized grain spawn.
  8. Allow mycelium to colonize all of the substrate.

How long does a mushroom flush last?

The immediate effects of using psilocybin wear off in six to 12 hours, though most people report continuing to feel the effects until they sleep and a "glow" the next day.

What is the best temp for mycelium growth?

Mycelium grew best during spawn-running when the temperature was kept at 75° F. (23·9° C.) During pre-cropping a temperature of 65° F.

Does mycelium need sunlight?

The light is not necessary. Mycelium grows well in dark conditions. In commercial growing it is due to the cost cut. The light is mandatory for primordium formation and fruit boddies development.

Does mycelium need sunlight to grow?

Mycelium requires some degree of light in order to develop mature fruiting bodies. While some growers prefer to use LED or CFL lights on 12-hour schedules, others simply rely on the indirect sunlight provided by a window. Some mushroom species require no light at all in order to grow.

How long does bulk substrate last?

Store your hard wood substrate in a cool and dry location. Hardwood substrate can keep for up to 3 months in these conditions. There will be no need to rehydrated or sterilize the products a second time. If you need to store the product longer it can be refrigerated for up to 6 months and frozen for up to 1 year.

How long does it take for mycelium to colonize substrate?

If we only top spawn, then the mycelium has to grow through 22cm of the substrate (30cm x 3/4). At a growth rate of 6 to 7 mm/day, it will take roughly 31-37 days to colonize the bag entirely. If you mix the time to full colonization is faster. How fast depends on how thoroughly you mix your bags.

Can I reuse substrate?

Yep you can reuse it. If it is (was) a nutrient rich substrate it will be less potent now. I have been reusing the same substrate for years :) Never baked it or anything.

What are the disadvantages of perlite?

As with so many other products, perlite has both its advantages and disadvantages as a growing media.
  • Water can drain away quickly. ...
  • Being so lightweight, perlite can be blown away and tends to float in excess water.
  • Nonrenewable resource. ...
  • Dust can create respiratory problems and eye irritation.

Is vermiculite or perlite better?

Vermiculite helps hold moisture in the soil so it's consistently available for plants to use. If you're looking for a soil additive to help make sure plants get plenty of drainage and aeration, perlite is a better option.
