Unstable greenhouse temperatures can stress plants, waste electricity, and make frost protection harder to manage.

Automatic Heating and Cooling Control for Year-Round Growing

The Bio Green Thermo2 is a digital greenhouse thermostat designed to control heaters, fans, ventilation systems, and heating cables automatically. It helps keep your greenhouse, grow room, or propagation area within your chosen temperature range, so you do not need to keep adjusting equipment by hand.

At £49.99, it is a practical plug and play greenhouse thermostat UK growers can use for frost protection in winter, cooling support in summer, and steady propagation temperatures all year round.

Key Benefits

Controls up to 3000W of equipment, making it suitable for many greenhouse heaters, fans, heat mats, and heating cables.
Wide -50°C to +99°C temperature range gives flexible control for overwintering, propagation, storage, and summer ventilation.
Dual heating and cooling function lets you manage both winter warmth and summer airflow from one controller.
2.8m sensor cable allows more accurate readings from the area where your plants actually sit.
Energy-saving automatic switching helps reduce wasted power by activating connected equipment only when needed.

Bio Green Thermo2 Digital Greenhouse Thermostat – 3000W

Nice piece of equipment

Nice piece of equipment, I bought this for my new greenhouse and have never tested it in there yet as I haven't installed the electrics yet. I have however tested it's accuracy indoors. I have to say it's display reads 1 degree C too high - this did not surprise me as I had several thermometers in the same room and they ALL varied as to the real temperature. It is nice to look at and easy to set. Do not loose your instruction book however. It has a 'Cooling'/'Heating mode, ie It will switch only the fan on when your greenhouse gets too hot as well as the heating element in winter - Very useful. Probably one of the best on the market in my view at that price level.

Accurate to 1degree smart appearance. Value for money and reliable

Pity about the instruction manual!

Just took delivery of a second Biogreen Thermo 2, having set up and used (successfully) the first one since November 2013. Both used to control heating in greenhouse - original for space heater and new one for soil-warming cable. Set up the new one exactly according to the instructions that came with it, only to find it would not store the set temperature (set at 20 deg C) but immediately defaulted to 10 deg C. Then I discovered that the instructions for setting the required temperature (page 12 of booklet) on the new one were wrong. These instructions said "Press the up or down button briefly to switch to setting mode. - - - Using the Up and down buttons you can change the temperature in 1 deg C steps. After you have set a new temperature it is saved automatically and the menu closes after 3 seconds." This did not work!However, as I had another, 16 month old unit I checked the instruction manual and found the setting instructions were very different - online were the same as the older ones and said: "Press the down button for 3 seconds to reach the setting mode. - - - Using the Up and down buttons you can change the temperature in 1 deg C steps. To store the selected temperature press the 'C/H' and down buttons simultaneously, (within 10 seconds, otherwise the set value will not be recorded)."The older instructions worked. Not too clever, sending out the wrong instructions but apart from this, they seem to be very good functional thermostats - that's why I bought the second one.

A bit too basic for the money

The unit is of industrial standard. However, one major design defect, there is no over ride switch to allow you to turn your applaince, instead you have to unplug your heater from the unit, unplug the unit from the mains and then plug your heater into the mains.Alternative is to reset the temperature to a lower one, good luck, it can be frustrating to do.I bought the unit to maintain the temperature in my conservatory, as be have a number of exotic plants and want to maintain a minimum temperature, and when we want to use the conservatory we need to boost the minimum temperature.The unit is ideal as a frost protector, say for a green house, or for when we are away to maintain a minimum temperature in the conservatory, but limited otherwise.

Accurate and easy to use thermostat

Easy to set up with a reasonable length remote sensor cable although a little more would be nice.I use this in my Orchid house for running a heater. Set the heater thermostat as high as it will go and plug it in. Far more accurate than heater thermostat and it enables me to place the heater low to the ground but sense the temperature at bench height. The differential setting ensures not too much cycling occurs.Easy to turn on and off. Seems to store settings after power cuts. Great bit of kit!
