The Gourmet Mushroom Problem

Gourmet mushrooms are delicious and healthy, but are rarely available.
Solution feature image

Poor quality and limited variety in stores

Gourmet mushrooms in stores are limited in variety and often sweating inside plastic packaging. You’ll pay a premium for poor quality and wasteful packaging due to their short shelf life. They're typically imported from overseas so by the time they hit your kitchen, they’re often well past their prime.

Solution feature image

Foraging is high effort, low yield

Deadly lookalikes exist, foraging requires expert knowledge for safety. Even when found, wild mushrooms are often past their prime or insect-infested, and the short seasonal window makes foraging more effort than reward.

Solution feature image

Hard to grow at home

Mushrooms thrive in humid, cool climates — they're sensitive to variable climates and the dry warm air of homes is not suitable. Unless you live in a rainforest, consistent fruiting is a big challenge.

Solution feature image

Grow kits require daily misting

Grow kits are a fun low-cost option but they require constant misting, multiple times a day for at least 7 days. If you go away for a weekend, your mushrooms will most likely dry out and fail.

Solution feature image

Bulky equipment and DIY setup

Serious growers rely on plastic tubs or grow tents with bulky equipment to manage humidity, CO₂, and temperature. These setups are best hidden in a garage and demand serious DIY effort to duct in humidifiers, fans, and heating or cooling systems.

Frequently asked questions

How do I get started?

Getting started is simple. First, prepare or purchase a mushroom grow kit or spawn bag suited to the species you want to cultivate. Next, place it inside the Grolia Flush cabinet and follow the step-by-step instructions included in the user manual. The cabinet will automatically control humidity, temperature, and airflow so you can focus on watching your mushrooms thrive.

Why are my mushrooms not growing?

There can be several reasons mushrooms fail to grow:


Make sure the cabinet is maintaining proper humidity, temperature, and fresh air exchange.

If your growing substrate or spawn has been contaminated with mold or bacteria, it can prevent mushroom growth.

Some mushroom species are more finicky, and low-quality spawn can result in slow or stunted growth.

Check all environmental settings, ensure your substrate is contamination-free, and follow the recommended cultivation procedures for your chosen mushroom species.

How many mushrooms can I grow?

The quantity of mushrooms depends on the strain you choose and the size of the substrate or grow kit. Generally, the Grolia Flush cabinet can fit one to two typical-sized grow bags or trays at a time. Under ideal conditions, users often see several flushes of mushrooms from a single grow kit, providing a steady supply.

Who is this product for?

Anyone interested in cultivating mushrooms at home can benefit from Grolia Flush. Whether you’re a beginner looking for a low-hassle way to grow gourmet mushrooms or an experienced cultivator seeking a controlled environment, the Grolia Flush cabinet is designed to simplify the mushroom-growing process.

What does Flush do?

Grolia Flush is an automated fruiting chamber designed specifically for mushroom cultivation. It manages critical factors such as humidity, temperature, and fresh air exchange, freeing you from constant monitoring. Essentially, it creates the ideal environment for mushrooms to develop and fruit successfully.

What if I grow mould or dangerous mushrooms?

Mould/Contamination: If you see mould, isolate and remove the contaminated substrate immediately to prevent spread. Clean and disinfect the cabinet before using it again.


Dangerous mushrooms: Only grow species you’re certain about. If you’re unsure of a mushroom’s identity or safety, consult reliable sources or a professional mycologist. Always use reputable spawn suppliers to minimize risks.

Are CO₂ and spore levels safe?

Grolia Flush is designed with fresh air exchange and an exhaust system to help maintain a safe balance of CO₂. Spore levels from most edible mushrooms are generally considered safe for healthy adults. If you have allergies or respiratory sensitivities, consult a healthcare professional before cultivating mushrooms indoors.

Mushrooms generate CO₂. Is that safe for my home?

Yes. Mushroom cultivation does produce CO₂, but in quantities comparable to other household sources (like indoor plants). The Grolia Flush system continuously exchanges fresh air, preventing CO₂ buildup. For peace of mind, keep the area ventilated, just as you would with any indoor gardening setup.

How much electricity does it consume?

Energy usage varies depending on your climate conditions and how frequently the chamber needs to regulate temperature and humidity. On average, the Grolia Flush chamber operates at a low wattage—similar to running a small fan and humidifier. Actual consumption will depend on ambient temperatures and your chosen mushroom strain’s requirements.

What are the internal and external dimensions?

Internal Dimensions: Approximately 465 mm (W) × 310 mm (H) × 190 mm (D), offering enough space for two standard grow bags and trays.


External Dimensions: Approximately 640 mm (W) × 370 mm (H) × 220 mm (D). Ensure you have a suitable spot with a little extra clearance for airflow and ventilation.

Can I grow magic/psychedelic mushrooms?

Grolia Flush is designed for legal mushroom cultivation. Laws vary greatly depending on your region, so check local regulations before attempting to grow any prohibited species. Grolia does not endorse or support the cultivation of any illegal substances.
