The details
Flush is designed and built in Newcastle, NSW, for Australian kitchens. It sits on a bench, plugs into a standard power point and takes about five minutes to set up.
Ask us a question640 mm wide, 370 mm high and 220 mm deep, so it sits on a kitchen bench. Inside there’s room for two standard blocks: run two varieties side by side, or stagger them for a rolling harvest.
Usually much less than its maximum of about 120 W. It works hardest in summer, when it is cooling; in winter and milder weather it uses far less. The regular job is topping up the reservoir, and a full one lasts at least a week. Flush tells you on screen when it is running low.
Connect Flush to Wi-Fi to check temperature, humidity and CO₂ from your phone or computer and change settings without being at home. Software updates install themselves. Flush needs a 2.4 GHz network, which most home routers broadcast; the Wi-Fi guide covers setup.
Free delivery anywhere in Australia with FedEx. Every Flush is covered by a 12-month warranty from the day it is delivered, on top of your rights under the Australian Consumer Law.

Climate controlled
Mushrooms are fussy about temperature, humidity and fresh air. Flush looks after all three around the clock, warming the chamber in winter and cooling it in summer. Your regular job is topping up the water.
Fresh air exchange
Growing mushrooms breathe out CO₂. If it builds up, you get long, thin stems and small caps. Flush exchanges fresh air continuously to keep CO₂ down, so caps grow thick and meaty.
A preset for every variety, set in one tap.
Touchscreen presets
Choose a preset and Flush sets the temperature, humidity and fresh air for that mushroom. If you’ve grown before, Advanced mode lets you set your own targets.
Generous harvests
Some oyster varieties are ready about a week after you cut the bag open. Most blocks are ready in two weeks and fruit two times, getting smaller each time.

Wi-Fi connected
Connect Flush to Wi-Fi to check temperature, humidity and CO₂ from your phone or computer, and change settings without being at home. Software updates install themselves, so Flush keeps improving after it arrives.
Made in Newcastle
We design and build every Flush in our Newcastle workshop, and we’ve been refining it since our first prototype in 2022. When you have a question, the people who made it answer.
