Once you've decided to grow your own magic mushrooms, it pays to be well prepared. You need a few things to get fully started, and Dutch Smart has lined that information up for you. The easiest option is a grow kit. Most of the ingredients and supplies are already included, so you don't have to hunt down separate materials. There are also different grow kits, for example for beginners and for more advanced growers. A grow kit usually contains a growing tray, spores, a spore syringe, a grow bag with air filter, an alcohol wipe and a manual.
Growing magic mushrooms isn't always easy. Professionals sometimes spend months on it. Luckily, with a magic mushroom grow kit you only have to wait a few weeks before you can harvest. So the ready-to-use kits really are recommended if you've never grown mushrooms before.
Dutch Smart carries several types of grow kits and additional supplies, matched to different levels and goals. Below is an overview of what's available.
The best-selling option: a ready-to-use tray with fully colonized mycelium. You take the kit out of the box, follow the steps in the manual and wait for the first flush. Available in popular Psilocybe cubensis strains such as McKennaii, Mexicana, B+ and Golden Teacher. Most kits produce several flushes, so a single set gives you two to four harvests.
More volume, higher yield per flush. The XL grow kits contain a larger substrate block that is already fully colonized. A good fit once you have a first grow under your belt and want to harvest more per cycle. Across all flushes, the total yield from XL sets is considerably higher than from standard kits.
Copelandia species contain higher concentrations of psilocybin than most Psilocybe cubensis varieties and call for a more precise approach. Intended for advanced growers who already have experience with standard grow kits and know how to handle a stronger species.
Funglandia grow kits contain colonized substrate from selected cubensis strains, known for stable colonization and consistent fruiting bodies. For growers ready to move toward strain-specific cultivation, after one or two successful rounds with a standard grow kit.
Don't feel like going through a growing process? Magic truffles (sclerotia) are ready to use straight away. Truffles contain the same active compounds as magic mushrooms, psilocybin and psilocin, and are legal in the Netherlands. Available in several types and strengths.
A liquid culture syringe contains living mycelium in a sterile nutrient solution. The spores have already germinated, which shortens colonization time considerably compared with regular spore syringes. You inject the liquid straight into your own substrate. Less chance of contamination during the early colonization phase. Bottles of 5, 10 or 25 ml, supplied with an empty syringe, alcohol wipes and instructions.
You don't actually need a large space or special lighting to grow magic mushrooms. What matters most is using the right materials, and above all that they are clean. At Dutch Smart you'll find various growing supplies so you can work cleanly and effectively. Think of an apron, gloves, face masks and disinfectant lotions.
That same category also includes a heating mat: it warms the substrate and keeps the activity of the growing medium up to level. Handy in winter, when room temperature drops too low for optimal growth. The heating mat is available in 5 or 7 Watt.
Whatever products you use to grow magic mushrooms, make sure you read up properly from the start. Using materials incorrectly costs you your harvest, time and money. On the manuals page you'll find step-by-step explanations including videos. For more background, read the knowledge base, for example about the right time to pick. Got questions?

If you want to go through the full growing process yourself, you start with spore syringes or spore ampoules. A spore syringe contains a suspension of spores in sterile water and is used to inoculate substrate or growing medium. Spore ampoules contain the same suspension but are sealed airtight, which makes them last longer.
This is the most time-intensive method, but also the most instructive. You see the entire colonization process from start to finish. Preferably use liquid culture syringes if you want the mycelium to grow faster: the spores are already germinated in these, which shortens colonization time considerably.
Psilocybin mushrooms are psychoactive substances. Responsible use starts with good preparation. A few basic rules:
Never use magic mushrooms on your own, certainly not the first time. Make sure there is a sober trip sitter who can keep an eye on the situation if needed. Choose a familiar setting, preferably at home or in nature, and avoid busy or unfamiliar places.
Dosage depends on the species. Dried Psilocybe cubensis contains on average 0.6 to 1% psilocybin per gram of dry weight. A common beginner dose is between 1 and 1.5 grams dried. Copelandia species are considerably stronger and require lower doses, usually 0.5 to 1 gram dried. Read more about dosage and effects in our knowledge base or check the latest articles on the blog.
Never combine magic mushrooms with lithium, MAO inhibitors or antidepressants. Only use if you are 18 years or older. Do not drive and do not operate machinery during or after use.
Age limit: this product is intended exclusively for people aged 18 and over. Dutch Smart does not sell products to minors.
With a 100% mycelium grow kit, it takes an average of 1 to 3 weeks to reach the first harvest, depending on the ambient temperature and humidity. The ideal temperature is between 23 and 26 degrees Celsius. If temperatures are too low, growth slows significantly; if temperatures are too high, the risk of fungal infection increases.
Most grow kits yield 2 to 4 flushes. The first flush is usually the largest. After each harvest, soak the kit in cold water for 12 hours to rehydrate the mycelium. The total yield across all flushes varies by strain and kit, but is generally higher for XL kits than for standard kits.
Green mold (Trichoderma) is a sign of contamination, often caused by insufficient sterility during inoculation or harvesting. An infected kit can almost never be fully recovered. Dispose of the kit in a sealed bag, disinfect the workspace, and start over with a clean set. Prevention is key: always work with clean hands and gloves, and disinfect all your materials beforehand.
A spore syringe contains spores suspended in sterile water that have yet to germinate. This process takes two to four weeks and carries a slightly higher risk of contamination in the early stages. A liquid culture already contains active, pre-germinated mycelium: colonization occurs more quickly and is more reliable. Liquid cultures are more suitable if you’re managing multiple batches at once or want to harvest as quickly as possible.
Harvest just before the membrane under the cap begins to tear. Once it tears, the mushroom releases spores and loses weight and potency. Read more about the right time to harvest in the knowledge base: Harvesting magic mushrooms: how, where, and when
Fresh magic mushrooms (fruit bodies of Psilocybe species) are prohibited in the Netherlands. Mycelium and spores are exempt from this ban: they do not contain psilocybin. Dutch Smart sells cultivation kits for legal mushroom species. Always check local laws before you get started. Truffles (sclerotia) are legally permitted and freely available.
