Do this by holding the 'set' button for 3 seconds and using the 'up' and 'down' buttons to choose your desired level. If you wish to switch between Fahrenheit and Celsius, press and hold one of the 'up' and 'down' buttons. Holding 'up' will switch to Celcius and holding 'down' will switch to Fahrenheit – an LED will light up on-screen to distinguish between the two. Give your seed the best treatment. If you have any questions and comments you want to germinate and sprout. Please do so in the seedbox (comment box) below. Finding the perfect seedling heat mat comes down to three features: maintaining the ideal temperature for germination, a high water-resistant rating, and durability.

Most plants are expected to suffer some temperature swing, where the temperature is warmer during the day and cooler in the night. When the mat is constantly switched on the temperature swing will not be there so that the plant continues to grow. Whether you're growing some tea leaves or herbs to garnish meals with, plants generally need a warm temperature. Having a seedling heating mat properly placed underneath (or wrapped around a jar, but we'll get to that later) artificially creates optimal conditions. They're a godsend if you happen to live in colder regions! For example, the optimal temperature for growing aubergines may be 24 degrees Celsius and the optimal temperature for growing tomatoes is 20 degrees Celsius, then I would set the heat mat to 22 degree Celsius. This will get the best from both, with only a slight deteriorate in germination times. This temperature on the mat is a handy guide for those who do not know what the optimal germinating temperature to use. This is an effective way of controlling temperature, so any wide temperature fluctuations outside can be controlled to a tight tolerance that not an even an electric propagator will give. WHAT YOU GET? The device is so durable that it can be used both indoors and outdoors in the greenhouse. It works great in hot and dry conditions without fear of causing damage.The Grow Gadget Heat mat is used to maintain consistent temperatures inside your propagator at all times, giving seedlings and cuttings the best possible start during their most critical period. How the Grow Gadget Electric Heat Mat Works:

Propagation Heating Mats - also known as a heating mat for plants or Germination Mats - are designed to combine two main features - the heat mats for plants encourage seed germination and root formation by providing an even base of heat that keeps soil warm and provide you with maximum flexibility as when not in use, they can simply be rolled up and stored away until needed again which makes these plant heat mats ideal for busy greenhouses or compact spaces. Plant heating mats can be used just about anywhere - in your greenhouse , conservatory or indoors - turning any staging or benching into a large propagator. The propagation heating mats are simply unrolled, plugged in, and they are ready to use. Believe me that it does save days, where every seed germinates 3 days earlier than if no heat has been applied. It is a great device for those impatient gardeners. The thermostat is such a great addition, switching on when it is required, switching off when it is not. If you use a thermostat the plant will not be exposed to heat 24 hours per day, so only get heat when the plant needs it and therefore saving energy when it is not required and switching on when the temperature of the compost drops by 1 degree Celsius.Normally, crops have no problem sprouting when they're in season; the environment is already providing the ideal temperature to start germinating. This presents a question: What if you want a fruit or vegetable that isn't in season? That's where a heating mat comes in handy. It's a constant source of warmth for seeds, allowing for germination to occur regardless of the seasons. Q: What Should I Look for in a Seedling Heat Mat? If you want to give your seeds a great head start, then I recommend you buy this heat mat and thermostat here. The thermostat is a must to my eyes and is optional, as you can buy the product without it, but to me, it makes sense to buy it. You do not what to overheat your precious seeds. The problem with most mats is that they come without a thermostat. This means that the mat is constantly switched on, so the compost is constantly heating. This means that the plants do not get any rest.
