You can grow gourmet mushrooms in shaded outdoor spaces, dark indoor rooms, or alongside community projects. The right location depends on the species you’re cultivating, how much space you have, and whether you want to grow alone or with others. We’ve grown successfully in urban South London gardens, community labs, and kitchen cupboards—each works for different growers and goals.
Why location matters more than you think
The first decision isn’t ‘indoors or outdoors’—it’s what you’re trying to grow and why. Different gourmet mushroom species have different needs. Oyster mushrooms tolerate shade and fluctuating temperature. Lion’s mane and shiitake prefer cooler, more stable conditions. Where you grow determines which species you can reliably fruit, how often you harvest, and how much active management the crop demands. I’ve seen growers invest in heated indoor rooms when they could have succeeded outdoors with species that thrive in their local climate. Start with your location; choose your mushrooms second.
The second factor is your own workflow. Are you home most days to monitor moisture and temperature? Do you have secure outdoor space, or would a cupboard under the stairs be more practical? Growing mushrooms isn’t complicated, but it does require attention—checking substrate moisture, spotting contamination early, harvesting at peak ripeness. The best location is the one you’ll actually visit regularly, not the one that looks most romantic on a garden design.
Growing mushrooms indoors: dark spaces, shelves and kitchen setups
Indoor growing suits small spaces and year-round production. You don’t need much: a dark corner, a shelf unit, and consistent temperature between 12–18°C for most gourmet species. A spare room, garage corner, or even a cupboard works. Mushrooms need very little light—they’re not plants—but they do need ventilation to prevent mould and moisture buildup. A small fan pointing at your fruiting blocks, or simply opening the door daily, is often enough. Humidity matters more than light. Most indoor growers use basic humidity trays (water-filled trays beneath the mushrooms) or spray the growing area lightly twice daily.
The advantage of indoor growing is control. You manage temperature, so you can fruit mushrooms year-round, even in winter when outdoor conditions are too cold or wet. Small-scale indoor setups—two or three fruiting blocks on a shelf—work brilliantly for home cooks and educators who want fresh mushrooms for weekly cooking. We’ve worked with home cultivators in West Norwood and across South London who grow small batches indoors between market days and workshops. If you’re growing for personal use or testing species before scaling up, indoor is usually where to begin.
Growing mushrooms outdoors: shade, moisture and seasonal timing
Outdoor growing works in shaded spaces: under trees, against north-facing walls, under eaves, or in a dedicated garden bed with a shade cloth. Mushrooms don’t need direct sun—too much sun dries them out. They need consistent moisture, shade from harsh afternoon light, and shelter from strong wind. A shaded garden corner is ideal. If you have no garden, a courtyard, balcony with shade, or even a disused alleyway (with permission) can work.
Outdoor growing is seasonal but productive. Species like oyster mushrooms fruit reliably in autumn and spring when temperature and humidity are naturally high. Summer requires more vigilant watering; winter is usually too cold. Many growers use outdoor space for heavy cropping during peak seasons, then shift to indoor maintenance through summer. We’ve seen successful outdoor setups in South London gardens where substrate-filled logs or blocks sit stacked in shaded corners, producing multiple flushes through autumn without artificial intervention. Outdoor growing also teaches you how mushroom species follow natural rhythms—valuable knowledge whether you’re growing for your table or thinking about foraging.
Community spaces: shared labs and collective growing
If you don’t have home space, or want to learn before committing resources, community mycology spaces are real alternatives. We work closely with the Community Mycology Lab at Remakery Brixton, where people learn and grow together. There’s also the South London Mushroom Club, where members share knowledge, equipment and sometimes shared growing space. These communities exist specifically because mushroom growing is collaborative—beginner growers benefit from mentorship, and experienced cultivators value the exchange of species, techniques and harvests.
Community spaces offer several advantages: you pay per session or membership rather than buying full equipment; you have access to experienced growers who spot contamination quickly; you can trial expensive species or techniques without sole financial risk; and you’re part of a learning loop that accelerates your progress. For educators and people new to cultivation, community settings are also where confidence grows. If you’re thinking about growing but uncertain whether you’ll stay committed, or if space is tight, start here. Many growers use community sessions to develop skill before setting up at home or at work.
Matching your location to the mushroom species you want
This is the practical grid. Oyster mushrooms are forgiving indoors and outdoors, tolerating shade and temperature swings between 8–20°C. They suit beginners in almost any location. Lion’s mane prefers cooler, more stable conditions (12–18°C) and benefits from indoor control or a shaded outdoor space in a mild climate. Shiitake is slower but reliable outdoors under partial shade, especially on logs. If you live in a warm flat with no outdoor access, oysters on a shelf are your best bet. If you have a cool garage or garden shed, you have more flexibility. South London’s mild, damp climate is actually excellent for autumn and spring outdoor growing—one reason we’ve built relationships with local restaurants and markets through consistent seasonal supply from garden and community spaces.
What to check before you pick your growing location
Before you commit, ask yourself: Is the space consistently cool (below 20°C most of the year, or heated to 12–18°C in summer)? Can you control moisture easily—either by spraying, misting, or accessing natural humidity? Is there air movement (even a small fan counts)? Is the space dark or shaded? Can you access it at least once or twice daily? Are you growing alone or with others, and does the location reflect that? For outdoor space, is it genuinely shaded, or does it get afternoon sun that’ll dry substrate quickly?
The final check: talk to other growers. Visit a workshop at a local studio like ours, join an online community, or spend an hour at a community mycology lab. You’ll see real setups, learn what works in your local climate, and often discover that the simplest location—a shelf in a cool room, a shaded corner, or a slot in a shared lab—is exactly what you needed. Growing mushrooms isn’t about perfection; it’s about matching your location to your species and your commitment. Get that match right, and the rest follows.
