Magic Mushroom Grow Kit FAQ: All Questions & Solutions

504 Views 0 Liked

With a grow kit from Next Level, growing your own shrooms is a breeze. Our grow kits are produced under the strictest hygienic conditions, are packed with mycelium, and contain a carefully crafted, purely natural substrate to allow your shrooms to grow absolutely optimally. This makes the process almost as simple as giving your kit water and waiting - and in the vast majority of cases, this will result in a successful harvest of your own magic mushrooms within 1 to 3 weeks.

However, sometimes you may encounter questions or problems during your grow. Growing shrooms is a natural process that almost always goes well, but it still depends on many different factors, such as temperature, humidity, light, unwanted molds or bacteria in the environment, etc. In this blog, we have collected all the problems, questions & answers you might encounter during the growing process. Let's grow!

Magic Mushroom Grow Kit FAQ

Where do I find your grow guide for growing magic mushrooms?

You can find our Cubensis magic mushroom grow guide here. If you grow Copelandia, follow our Copelandia magic mushrooms grow guide.

How long can I store my magic mushroom grow kit and what is the best storage method?

Store your unopened grow kit in the refrigerator (between 2°C and 9°C) until you are ready to start your grow. Although unopened grow kits can in principle be stored for 3 to 6 months under the right conditions, we always recommend setting up your kit as soon as possible after receiving it for the best results. The mycelium (the 'roots' from which your mushrooms will grow) is still fresh then and has not been 'sleeping' for a long time.

Only a few mushrooms appear in my kit. Is my grow kit functioning properly?

The number of mushrooms that grow can vary per kit and per flush. Numerous factors, such as temperature, humidity, and light conditions, can play a role, so it is not always easy to determine the exact cause. In the images below, less than optimal growing conditions were the cause. In particular, the mushrooms and kit on the left do not look very good.

It is normal for the quantity of shrooms to decrease slightly with each subsequent flush (harvest), even if there is nothing wrong with your growing conditions or your grow kit. In some cases, it may also simply take a little longer for the pins to appear. Be patient and ensure the right growing conditions. If there are still no mushrooms after 3-4 weeks, or if your grow kit produces very few shrooms from the first flush on, then contact Next Level's customer service for advice.

Why do my mushrooms develop at the bottom or on the side of the grow kit (side pins)?

Side pins usually occur when the kit does not contain enough water, the humidity is too low, or there is excessive ventilation. As a result, or sometimes (also) due to temperature differences between the bottom and top of the kit, the shrooms may find the growing conditions more favorable at the bottom or on the side of the kit than at the top. Another factor may be that the substrate has not been (sufficiently) pricked with a fork before the grow started - or pricked too deep.

In any case, ensure adequate misting and keep the grow bag closed until the first pins appear. If the side pins persist, you can carefully place the substrate on its side or upside down. Make sure you work with very clean hands or latex gloves to prevent contamination of the kit. Also check if the temperature at the bottom of the kit does not differ greatly from that at the top. This can occur, for example, when using a heating mat in winter, when the bottom of the kit is warm enough but the ambient temperature is (too) low. However, this is an exception; presumably drying out is a more common cause.

Why do my mushrooms suddenly stop growing?

Sometimes it happens that some mushrooms in your grow kit stop growing before they are fully grown. This phenomenon is known as "mushroom aborts" and these shrooms can often be recognized by their smaller size and darker or discolored caps. Some common causes of growth stoppage are stress due to fluctuations in temperature, humidity or CO2 levels, contamination of the kit due to unhygienic work, and insufficient ventilation causing CO2 levels to become too high.

To minimize the risk of mushroom aborts, it is important to closely monitor your growing conditions. Ensure adequate ventilation in your growing space and always work sterile to prevent contamination. Consider using tools such as a thermometer and hygrometer to measure temperature and humidity and adjust if necessary. Want to learn more about mushroom aborts? Read our blog.

If you do find aborts in your grow kit, in many cases you can still use them, unless they are clearly moldy or darkly discolored. Despite their small size, they often still contain active substances and can even be more potent than fully grown mushrooms. If the kit is not visibly contaminated with unwanted molds, you can try restarting the kit using a cold shock after removing the aborts.

My mushrooms have a blue tint. Is this normal?

A blue discoloration, also known as "blue spots" or "bruising", is usually not a cause for concern. This natural phenomenon is caused by the oxidation of psilocybin, the active substance in magic mushrooms. It has no negative influence on the quality or potency of your shrooms.

Why does my grow kit have white mold?

White, fluffy growth on or in the substrate usually indicates the normal development of the mycelium and is not a cause for concern. This is a sign that your grow kit is well on its way! The mycelium, the vegetative part of the fungus, grows through the substrate and forms a network of white threads before producing mushrooms.

However, if the fungal growth is excessive and shows an abnormal color, such as green, gray or black, this may indicate contamination by unwanted molds. In this case, it is important to carefully isolate and remove the affected parts without damaging the healthy mycelium. Keep a close eye on the kit and take extra hygienic measures if necessary to prevent further spread.

Regular inspection of your grow kit during the growing process is essential to distinguish between normal mycelium growth and potential contamination. If in doubt, you can always take a photo and contact Next Level's experienced customer service for expert advice.

My grow kit looks green. Is this cause for concern?

Green spots on your substrate often indicate fungal contamination, which can impede the growth of your mushrooms. The cause may lie in unwanted fungal spores in your growing space and/or not working hygienically enough. Carefully isolate the affected parts and remove them if possible without damaging the healthy mycelium. Keep a close eye on the situation. If you are growing with multiple kits, isolate the affected kit from the others. If your kit looks like the images below, your kit is quite contaminated and it is better to replace it. For a next grow, it may be wise to use a different, more sterile growing space.

There are yellow spots visible in my kit. What does this mean?

Just as green discoloration is not a favorable sign, yellow spots may indicate bacterial contamination. This can negatively affect the development of your shrooms. The cause of this bacterial growth can include not working sterile enough. Keep a close eye on the situation and take measures if necessary to prevent further spread, such as isolating or removing affected parts. If this does not help, or if the yellow discoloration is already too seriously spread in/on the substrate, it is better to replace your grow kit.

What does it mean if my grow kit shows brown spots?

Brown discoloration of the substrate can be a sign of unwanted molds, which can sometimes be present unnoticed in your growing environment. Although this is not always harmful to your shrooms, it is important to closely monitor the kit and remove any contaminated parts to prevent further spread. In the images below, the kit is clearly already too seriously contaminated to produce mushrooms. In that case, replace your kit with a new one and try a next grow in a more sterile growing environment.

What should I do if my grow kit has received too much water?

Excessive water supply can lead to drowning of the mycelium and unwanted mold growth. If you notice that your kit is too wet, let the excess water drain away and place the kit in a well-ventilated place to dry out until the substrate feels moist but no longer drips. Adjust the frequency of misting to prevent this in the future.

Has my grow kit dried out? If so, what should I do?

If you suspect that your kit has dried out, spray it thoroughly and close the grow bag again with the paper clips; or soak the kit again, put it back in your grow bag and close it. Check daily and mist if necessary to keep the substrate moist. The mycelium may need several days to weeks to recover.

Creating conditions for optimal growth

What does the perfect environment for my grow kit look like and what temperature should I maintain?

A hygienic, draft-free and mold-free environment with a constant temperature and enough indirect light is ideal for growing magic mushrooms. Mushrooms thrive at a temperature of 20-25°C and a humidity of 90-100%. Choose a spot away from direct sunlight and drafts. A heating mat can help maintain a constant temperature, but never place the kit directly on the mat to prevent drying out.

Do my mushrooms need light, or can I leave the kit in the dark?

Although mushrooms do not need direct sunlight to grow (this is even discouraged), light does play an important role in the development of magic mushrooms. We recommend placing your grow kit in a location where sufficient indirect daylight enters, such as near a window - but make sure that direct sunlight never falls on the kit or the mushrooms, as this negatively affects or even stops growth.

On the other hand, you never want to leave your grow kit in the dark, because a lack of light can also slow down or prevent the growth of your mushrooms. So look for a balance where your kit receives enough indirect daylight to stimulate growth, without exposing the mushrooms to direct sunlight, darkness, intense heat, or drying out.

Is the use of a heating mat necessary for my grow?

A heating mat can be a valuable tool to keep the temperature stable, especially if you are growing your grow kit in an environment where the temperature fluctuates too much or regularly drops below 18°C. Magic mushrooms thrive best at a constant temperature between 20-25°C. If you cannot guarantee this temperature, a heating mat can offer a solution.

However, be careful never to place the grow kit directly on the heating mat, as this can lead to drying out of the substrate. Always ensure a temperature-resistant barrier between the mat and the kit, such as a piece of styrofoam, wooden slats, or a folded towel. Check the temperature regularly and adjust the distance between the mat and the kit if necessary to prevent overheating.

Also keep in mind that the temperature inside the grow kit itself may be higher than the ambient temperature. When in doubt, it is better to opt for a slightly lower temperature than to expose the mushrooms to too much heat. If you are able to maintain a stable temperature between 20-25°C without a heating mat, its use is not strictly necessary. In that case, do ensure a draft-free location away from air conditioners or windows.

With the right precautions and monitoring, a heating mat can be a useful tool to create the ideal growing conditions for your magic mushrooms, especially in cooler rooms or during colder months.

How often should I mist my shroom grow kit to maintain the right humidity?

Mist your kit carefully 1-2 times a day with clean, boiled and cooled off water to keep the humidity at the right level without damaging the mycelium. The substrate should feel moist, but not soaked. If excessive condensation forms in the grow bag, reduce the number of mistings. When the first pins start to appear, make sure that you never spray directly on the mushrooms to avoid spoiling your shrooms. Instead, spray on the inside of the growbag to maintain humidity.

How do I prepare to start my shroom grow?

Start by setting up a suitable growing space: a hygienic, draft-free place with a stable temperature around 22-24°C. Gather all necessary materials, including a spray bottle with clean water and disinfectant for cleaning your hands, so you are well prepared.

How do I ensure my grow kit stays clean and hygienic during the growing process?

Maintaining a clean and hygienic environment is very important for a successful mushroom grow. Always start by thoroughly washing your hands with soap and water or using a disinfectant before working with your grow kit. Wearing clean latex or nitrile gloves can provide extra protection against unwanted bacteria and molds.

Make sure your growing space is clean and dust-free before you begin. Use sterilized tools and materials when working with your kit and avoid unnecessary touching of the substrate or mushrooms. If your kit starts giving off an unusual smell or showing signs of contamination over time, immediately isolate it from any other kits to prevent spread.

Regular inspection and monitoring of your grow kit throughout the entire growing process is important to detect and address potential problems early on. By taking these precautions, you can significantly reduce the chance of contamination and create the best conditions for a healthy and productive mushroom grow.

What are the most common mistakes when growing mushrooms with a grow kit?

Some common mistakes include: giving too much or too little water, exposing the kit to direct sunlight or drafts, opening the grow bag too early, and not maintaining a hygienic working environment. Read more about the most common grow kit mistakes in our blog. Also, always follow the instructions from our grow guide to maximize your chances of success!

What does a 'cold shock' entail and how can I reset my grow kit?

A cold shock is a technique where you temporarily lower the temperature of your kit to about 5-10°C for 12-24 hours, in the refrigerator. This mimics the natural temperature drop that stimulates fruiting. You can apply this method between flushes to reset your kit and promote new growth.

Harvesting and maximizing yield

How do I know when it's time to harvest my mushrooms?

The mushrooms are ready to be harvested when the caps are fully opened. If you wait too long until the caps become flat and the edges curl upward, they will release black spores that can hinder or delay the next flush. Although this is not harmful, it can affect the next harvest. So preferably harvest before the mushrooms release their spores.

What is the most effective way to harvest mushrooms without damaging the grow kit?

Gently twist the mushrooms loose at the base of the stem, as close to the substrate as possible. This prevents damage to the mycelium and promotes a successful next flush. Use clean hands, gloves and/or a clean knife if the stems are difficult to remove.

How many grams of mushrooms can I expect per harvest and how often can I harvest?

The yield per kit varies, but averages between 20-200 grams of fresh weight per flush, depending on the growing conditions, the experience of the grower, and the quality of the kit. With Next Level, you can trust that you have a high-quality grow kit in your hands. Yields up to hundreds of grams are possible!

Most kits also provide at least 2 to 4 harvests at intervals of 1 to 2 weeks. After each harvest, you give the kit rest and start over with the soaking phase or cold shock. By working hygienically and following the instructions closely, you can realize up to 7 harvests from one kit! Do keep in mind that later flushes usually yield less than the first.

How can I increase the yield of my shroom grow kit?

Although the yield is mainly determined by the genetics of the mushrooms, the professionalism of the producer, and the quality of the substrate, there are a few things you can do to improve your chances. Ensure optimal growing conditions in terms of temperature, humidity, light, and ventilation. Always follow the instructions carefully for the best results. Do not harvest too early, but just before the caps release their spores: this way you harvest the greatest weight of mushrooms.

Other frequently asked questions

What is the best grow kit for beginners?

One of the best grow kits for beginners is our Golden Teacher Grow Kit, which is very easy to grow and will not be too strong for novice psychonauts (but never underestimate the power of magic mushrooms). If you prefer a different grow kit for your first grow, feel free: all our Cubensis grow kits are very easy to grow and will give you good harvests.

What is the difference between Copelandia and Cubensis grow kits?

Copelandia and Cubensis are two different types of magic mushrooms, each with their own unique properties and growing requirements. Copelandia mushrooms, also known as Panaeolus cyanescens or Hawaiian Copelandia, are known for their high potency and fast growth. They often have a darker color and a slimmer appearance than Cubensis mushrooms. Copelandia grow kits require a bit more experience and attention, as they are more sensitive to fluctuations in temperature and humidity. Read our extensive blog about Copelandia, the strongest psychedelic mushroom, here.

On the other hand, Cubensis mushrooms, or Psilocybe cubensis, are the most popular and widespread magic mushrooms. They are known for being relatively easy to grow and for their average to high potency. Cubensis grow kits are usually easier to use and more suitable for novice growers. They are also available in a wider range of varieties, each with its own unique appearance and effect.

If you are interested in growing Copelandia mushrooms, we recommend consulting our extensive Copelandia Grow Guide. This guide contains step-by-step instructions, tips, and tricks to help you successfully cultivate these fascinating and particularly potent mushrooms. You can find our Cubensis grow guide here.

Are Next Level's grow kits organically produced?

Although our grow kits are not organically certified, they are produced in a completely natural way, without the use of pesticides or other chemical agents.

What components make up the substrates of the shroom grow kits?

Next Level's grow kits contain a carefully composed mix of grains and nutrients that provide the mycelium with an optimal nutrient base to develop fruiting bodies (mushrooms).

I see shiny particles in my kit. Are these harmful if ingested?

The shiny particles are nutrients for the mycelium and are essentially harmless. However, they are not intended to be consumed. If a particle sticks to your mushroom, you can easily remove it by hand before consuming the mushroom.

Can I compost or reuse the remaining substrate after harvest?

You can add the substrate to your compost heap or dispose of it with the organic waste (without the plastic container). We advise against reusing the substrate for a next shroom grow, as the nutrients are largely used up and the risk of contamination increases. For the best results, it is best to order a new grow kit for your next grow.

Can I make my own substrate for growing mushrooms?

Although it is technically possible to compose your own substrate, we do not recommend this for beginners. Making a suitable and nutrient-rich substrate requires specific knowledge, materials, and equipment to prevent contamination. Next Level's grow kits are carefully composed by experts to guarantee optimal results. For the most reliable and efficient growing experience, we advise using professionally manufactured grow kits.

What should I do if I continue to experience problems with my grow kit?

If you are still experiencing problems with your grow kit despite following all the advice, do not hesitate to contact Next Level's expert customer service. They are ready to work with you to find the most effective solution for your specific situation.

We hope this comprehensive guide has helped you gain more insight into successfully growing magic mushrooms with a grow kit.
