XXL Mushroom Grow Tent
A roomy polypropylene fruiting tent for gourmet mushrooms. Built-in filter strips let fresh air pass in and out while the enclosed space holds the high humidity your fully colonised substrate needs to pin and fruit.

The short version
The XXL Mushroom Grow Tent is a self-contained fruiting chamber. You put your fully colonised substrate inside, hold the humidity up, give it light and fresh air, and the mushrooms fruit in a controlled space instead of an open room.
It is the largest tent we stock. The manufacturer states a 10 litre internal volume and a 7kg weight capacity, so it takes bigger blocks and trays than our XL. It is the tent only. You add your own substrate, and any humidifier or light you want to use.
What it is
A fruiting chamber, not a colonising space
A grow tent gives mushrooms the conditions they need to fruit: high humidity, fresh air, gentle light and a stable temperature. It is a collapsible chamber you set up indoors and fold away when you are done.
The body is polypropylene, which is durable and easy to wipe down between grows. Filter strips are built into the tent. These let oxygen in and let the carbon dioxide your mushrooms produce escape, without letting in the airborne contaminants an open tray would. The manufacturer states a 10 litre internal volume, a 7kg weight capacity and a footprint of about 47 by 57cm.
How to use it
Fruiting your gourmet mushrooms
Use the tent once your substrate is fully colonised and ready to fruit. Introduce fruiting conditions only after the substrate is fully colonised, as exposing uncolonised substrate to fresh air invites contamination. The numbers below are general targets for most gourmet species. Check the needs of your particular strain, as some prefer cooler temperatures or more fresh air.
Place the colonised substrate
Stand your fully colonised block, tray or tub inside the tent. Do not move substrate in until the mycelium has run through it. Sit it on a tray if it is likely to drip, and avoid letting water pool in the base.
Raise the humidity
Most gourmet mushrooms fruit best at around 80 to 95 percent relative humidity. Mist the inside walls by hand a few times a day, or run a small humidifier near the tent. Wispy aerial mycelium climbing the stems is a sign the air is too still and too wet, so add more fresh air if you see it.
Give it fresh air
The filter strips provide passive air exchange. Mushrooms take in oxygen and give off carbon dioxide, and too much carbon dioxide causes long thin stems and small caps. If your room is still, open the tent and fan it by hand a few times a day to swap the air.
Add light and watch the temperature
Mushrooms need only indirect light, enough to read by, to tell them which way is up. A timer running a low LED for around 12 hours a day is plenty. Most gourmet species fruit well in a range of about 13 to 24C, with oyster among those that prefer the cooler end. Check your strain, as figures vary between species.
Pin, fruit and harvest
Small pins appear first, then grow into full mushrooms over several days. Harvest before the caps fully open if you want the best texture. Then let the substrate rest and rehydrate for a second flush.
Specification
The numbers
| Size | XXL, our largest tent |
|---|---|
| Material | Polypropylene |
| Internal volume | 10 litres (manufacturer-stated) |
| Weight capacity | 7kg (manufacturer-stated) |
| Air exchange | Built-in filter strips |
| Footprint | About 47 by 57cm, manufacturer-stated |
The filter strips handle passive air exchange, so you do not need ducting or an inline fan for a home-scale grow. A humidifier is optional but makes holding high humidity much easier. Wipe the tent clean and let it dry before folding it away, so it is ready for the next grow.
Good to know
What this tent is not for
This is a fruiting chamber, not a sterile work area. It is not a still air box or a flow hood, so do not inoculate jars or open sterile bags inside it. Do your sterile work separately and only bring fully colonised substrate into the tent.
It is also not a colonising incubator. Colonise your grain or substrate in its container first, then use the tent for the fruiting stage.
Common questions
Frequently asked
No, you can mist the inside by hand, but a small humidifier makes it much easier to hold around 80 to 95 percent humidity.
No, it is the tent itself. You add your own colonised substrate and any humidifier or light you want to use.
No. It is a fruiting tent, not a still air box or flow hood. Keep sterile work separate.
Legal gourmet mushrooms such as oyster, shiitake and chestnut, once your substrate is fully colonised.
The XXL is larger, with a manufacturer-stated 10 litre volume and 7kg capacity, so it holds bigger blocks and trays.
For home-scale growing the strips give enough passive air exchange. In a very still room, open and fan the tent by hand a few times a day.
Yes. Wipe it down, let it dry, then fold it flat for storage. Clean it between grows to keep contamination down.
