Thermo Heatingmat

Grow magic mushrooms the whole year round. The thermo mat heats up your magic mushroom grow kit to 24°C. Now you can grow in the winter, cold nights and cold rooms.

Originally designed to heat up terrariums, this thermo mat has been adapted to fit one cubensis magic mushroom grow kit.

Availability: In stock

Product Description

A thermo mat uses electricity (230 V) to heat up. When touching the heating mat when it is on full power, it reaches up to 35°C. A process called ‘diffusion’ is omnipresent and diffuses some of that heat, so the magic mushroom grow kit, that is placed on top of the heating mat will be warmed up to 24°C. This is the ideal temperature for Psilocybe cubensis mushrooms to fruit.

Always check the humidity of the grow kit when using a heatmat. Water will evaporate quicker !


Which grow kits can be used with a thermo mat?

The active temperature of the thermo mat is 24°C, so you can use all cubensis mushroom grow kits with this thermo mat.

SupaGro does not recommend the use of a heatingmat for their mushroom growkits


When do you need a thermo mat?

The cubensis magic mushroom grow kits produce mushrooms only between 18°C and 29°C. When the temperatures are below 18°C, the mycelium in the magic mushroom grow kit goes into a dormant state. No mushrooms will grow. The use of thermo mats is strongly recommended in:

  • Autumn / Winter
  • Colder regions of the world
  • Cellars / cold growing rooms
  • Fluctuating temperatures (warm in the day/ cold at night)


What do you need?

To use a thermo mat, all you need is:

  • 230 V electricity. If this voltage is not available in your country, you can use a universal power adapter
  • Accessories to elevate the thermo mat from a solid surface and the grow kit


How to use a thermo mat

Using a thermo mat is easy.

1. Place the Thermo Mat on an elevated surface so that air can flow freely under the Thermo Mat. Here are a few tips on how to elevate the thermo mat from a solid surface. You can place the thermo mat on:

  • A pan-coaster
  • Shot glasses
  • Corks

2. Add some space on top of the heating mat to create an extra layer of air between growkit and thermomat.

3. Place the grow kit on top of the heating mat, use the lid if heating is too warm, this will give the kit some extra distance from the heat source. The grow box should be inside the grow bag with micron filter.
The thermo mat should not get wet!

4. Plug the power plug in the power socket and that’s it!

Updated Heating at Instructions: How to use the thermo heating mat

The thermo mat can be switched on 24/7 as long as the air can run freely under the thermo mat. This is important because it should not be allowed that the heat builds up in the thermo mat!

Note: The instructions of the Magic Mushroom grow kits mention that the grow kit should be placed back in the carton box. Do not do this when you use the Thermo Mat!

Good but careful!
This is necessary if you live in cold places but be careful you do not make it too hot! It had happened to me in the past. The problem is not the heating mat but you being careful, best to also get a thermometer to check the temp. every now and then and do not allow it to go too high (you do not want to dry your substrate or kill the mycel).

Heatmats NOT recommended
So these heatmats are the worst thing you can do. Even with enough space between desk/heatmat/growbox, this thing gets too hot, worst case you will put the growbox directly on top, your growkit will be destroyed. OUTDATED information and NOT recommended.
Even with a thermostat, lower heat will kill your mycelium, you need to heat up your ambient space.
Review by Yoram (Posted on 1/28/2020)
Works flawlessly
My mushrooms grow big and healthy on the heatingmat. I made long sticks out of clay that I placed between the desk-heatingmat and heatingmat-grow kit to diffuse heat.
The bottom of the grow kit is nice and warm 24/7 thanks to this product !
Review by Mirko (Posted on 1/26/2020)
Simple and reliable
Works perfectly.
But the temperature of my heatingmat itself is around 40°C.
So be careful not to overheat your grow box.
Learn the instructions and recommendations before use.

Placed it onto a fire-safe piece of ceramic with some metal diffusers, the temperature is always from 21c to 24c, always in the optimum range. Review by Kristjan (Posted on 11/20/2019)
Good job
I am happy with the mat. Works just fine. Review by Tze (Posted on 11/10/2019)
Works well

Does what its meant too. Review by oluwayinka (Posted on 2/17/2019)
Winter Necessity
A must for the colder months! Review by Damien (Posted on 2/15/2019)
Pretty Good but a little tricky to control
Most sources (including the gudes on here) will tell you to put smthn in between the heat mat amd the kit, however that I am on flush 2 and the surface is barley colonised. Almost all of them are on the sides near the heat source.
But when measured with an ir gun the surface has 23-24° comming of it.

I think you just gotta experiment a little and see what works best.

Ideal little thing.
A must have for shrooming
Review by TJ (Posted on 12/18/2018)
Thermo mat
It could be very good, however I don’t have any experience as I ordered this and paid it but NEVER EVER RECEIVED.
I definitely needed it to grow shrooms, but without that, shrooms don’t grow here and all went wrong.

Good product to the cold ambience
Nice to the cold environnement. Review by Nelma (Posted on 9/13/2018)
these are needed
For the colder winter growing months you will need these heat pads. They work just great! Make sure to have a gap between the bottom of the kit and the heat pad (elevated) for breathing. Review by Lexington (Posted on 7/27/2018)
Thermo matt/heater
Great little thermo matt... ideal for the cold nights, my shrooms definatley grew quicker and bigger on the heated matt compared to without it...A must have for the psychedelic entrepreneur :) Review by Luke (Posted on 5/21/2018)
Good but not perfect
Heats good, but would be better if could regulate the temperature of the mat.
I use it for heating right after taking out of Cold Shock. Then heat for 2 days.
Review by Toms (Posted on 5/1/2018)
