Looking for the best mushroom growing kits to grow mushrooms in your home? Then we suggest calling your new mushroom grow kit Spot or Fido.
Why? Well, mushrooms are more closely related to animals than to plants. Welcoming a mushroom growing kit into your house is like adopting a labrador retriever or a tabby cat. A little fun creature you look after, nurture, and love. Maybe even curl up in bed with.
Maybe not.
Luckily, grow kits for psilocybin-containing mushrooms are easier to take care of than a hamster, canary, or rabbit. Especially nowadays, when mushroom grow kits are shipped to your door and handle most of the work.
In this article I lay out six mushroom grow kit options that are available to you right now to start your mushroom growing adventure. You can grow Penis Envy, many types of psilocybe cubensis, or even more potent mushrooms. These make the process much simpler than the old ways–starting with a giant bag of bird seed that you will inevitably spill all over your house. These kits come ready to go with the most delicate steps where contamination is likely (sterilization and pasteurization) done by professionals with fancy technology like an autoclave or a laminar flow hood.
I hope that this can help many of you forge a closer relationship to the medicine that you consume and share.

The Mushroom Growing Kit Landscape in 2025 — Legal Context and What’s Changed
The mushroom growing kit market has evolved considerably since this article was written, influenced by shifting legal contexts, growing mainstream interest in functional mushrooms, and new developments in cultivation technology. Here is an update on what’s relevant for prospective growers.
Colorado’s Prop 122 changed personal cultivation legality. Colorado’s Proposition 122 (Natural Medicine Health Act), passed in November 2022, legalized the personal possession and personal use of psilocybin mushrooms for adults 21 and older. This explicitly includes home cultivation — adults in Colorado can legally grow psilocybin mushrooms for personal use. This represents a significant legal development for Colorado residents who had previously operated in a gray area. Oregon’s framework (Measure 109) does not include a personal cultivation provision — it only permits psilocybin through licensed service centers. Several other states and many cities have decriminalization ordinances that reduce enforcement priority, but do not create the same positive legalization as Colorado’s Prop 122.
The functional mushroom category has exploded. Growing interest in lion’s mane, reishi, chaga, cordyceps, and oyster mushrooms has driven substantial investment in the growing kit market, with new entrants offering more sophisticated all-in-one substrate blocks, mushroom grow tents, and automated humidity/temperature systems. Many of these innovations are legal, mainstream products available at garden centers and major retailers — not just specialty suppliers. This infrastructure has had an indirect benefit: it has made the general knowledge of mushroom cultivation more accessible and mainstream, and the equipment is increasingly available through normal retail channels. For cultivators in states where psilocybin remains illegal, the crossover between functional mushroom cultivation and psilocybin cultivation equipment is obvious and widely discussed in harm reduction communities.
Spore legality: still a patchwork. Psilocybin mushroom spores (which do not themselves contain psilocybin or psilocin) remain legal to purchase in most U.S. states for research, educational, and identification purposes. Three states — California, Georgia, and Idaho — specifically prohibit spore possession with intent to cultivate. Everywhere else, spore purchase is technically legal; the illegality in most states begins at the point of cultivation (when psilocybin begins to be produced in the developing mycelium). Spore vendors who sell for “microscopy and research purposes” are operating in this gray area. This distinction — legal spores, illegal cultivation — means buyers can legally purchase spores in most states but would be breaking state law by germinating them.
Frequently Asked Questions
Are mushroom growing kits legal?
It depends on the type of mushrooms. Growing kits for culinary and functional mushrooms (oyster, lion’s mane, shiitake, reishi, cordyceps, chaga) are completely legal everywhere in the U.S. and widely available at garden centers and online retailers. Growing kits containing psilocybin mushroom genetics are legal to possess in Colorado for adults 21+ under Prop 122 (personal cultivation legal). In Oregon, personal home cultivation is not permitted — only licensed service centers can produce psilocybin products. In all other U.S. states, cultivating psilocybin mushrooms remains illegal, though psilocybin spores (which don’t contain psilocybin) are legal to purchase in most states except California, Georgia, and Idaho.
What’s the difference between a mushroom growing kit and growing from scratch?
A mushroom growing kit provides colonized substrate — substrate (the growth medium, typically a blend of grain and wood products) that has already been inoculated with mushroom mycelium and is ready to fruit. You simply provide the right humidity and airflow, and mushrooms emerge from the block within 1–2 weeks. Growing from scratch involves sterilizing substrate, inoculating with spores or cultures, and waiting for colonization before fruiting — a process that takes 4–8 weeks and requires more equipment and technique. Kits are the entry point for most beginners: they eliminate the most failure-prone steps (sterilization and inoculation) and compress the time to harvest. The tradeoff is cost per gram of harvest and less control over genetics and substrate composition.
What mushrooms can you grow at home with a kit?
Culinary and functional mushrooms with widely available kits include: oyster mushrooms (pink, blue, golden — fastest fruiting, 1–2 weeks), lion’s mane (distinctive cascading teeth, mild seafood-like flavor), shiitake (slower, 2–4 weeks, complex flavor), reishi (slow-growing, woody, used medicinally), turkey tail (medicinal, used in immune support research), and chaga (grows on birch trees, typically foraged rather than cultivated). These are available at garden centers, specialty retailers, and major online platforms. Psilocybin mushroom kits are only fully legal in Colorado and for specific religious/research purposes. The functional mushroom market has been the primary driver of innovation in kit technology since 2020.
What conditions do mushrooms need to grow from a kit?
Most mushroom growing kits need four things: humidity (80–95% relative humidity for fruiting, which typically requires regular misting); fresh air exchange (CO2 buildup inhibits fruiting — most kits need ventilation 2–3 times daily); appropriate temperature (most culinary species fruit well at 65–75°F / 18–24°C, though species vary); and indirect light (mushrooms don’t need light for energy — they use it as a directional cue, so indirect ambient light helps them orient). The most common beginner mistake is keeping the kit too dry. Most kits come with instructions optimized for the specific species. The learning curve is the first batch; by the second or third flush from the same block, most growers have dialed in their environment.
