Sowing in a greenhouse, seedbed or warm bed is done at home and is very simple.

It is a process that allows us to reproduce our favorite seedlings or any other plant, saving a lot of money. Just retrieve the seeds from the plants in our garden, or buy sachets of seeds in garden shops, or on many online sites for a few euros. Good results are within everyone’s reach. You don’t have to be a professional gardener or a good green thumb to be successful in sowing. Just follow a few tips correctly and give both seeds and shoots and then small seedlings everything they need.

That’s what a seedbed is, what you need, how to set it up to get lots of healthy shoots and seedlings!

What is a Seedbed?

A seedbed, hot bed or mini greenhouse, is simply a plastic container of various sizes. It is the ideal environment where to germinate our seeds, controlling humidity and temperature. Having a good seedbed simplifies the work by obtaining the results.

The seedbed is equipped with a bottom container where the ready pots are to be placed. Many people choose to fill it directly with soil and sow. If we have seeds from several different plants, our advice is to use pots. It is also equipped with a transparent lid, with windows or cracks, which allow the circulation and exchange of air. Some models are already equipped with a heating element, or a heating mat, which allows you to keep a constant temperature inside the seedbed. If the model you have chosen, or the one we have does not have this accessory, you can buy it separately online, for example on Amazon or Ebay.

Now let’s better analyze the need to be more successful in sowing, and then more seedlings ready for spring, which will color our gardens and balconies.

Heating Resistance

Heating resistance means all the components that can be used to heat the seedbed, for example: a mat or a heat conductor cable. They are essential to keep the temperature suitable for germination, especially during the night, even when the temperature of the house can drop moderately. Remember that most of the seeds that are sown in February and March for germination, like a temperature ranging from 18 ° to 24 °.

The various mats differ in size and Watt (power). So if we already have a seedbed and we want to equip it with a heating mat, we should pay attention to the measures. The recommended power to have the seedbed soil warm to the right point is from 15 watts and up and should be placed under the seedbed, not inside!

The cable has the same functionality, you just need to have a bit of manual skills, it will be positioned in a coil on the shelf where we will put our greenhouse.

The prices of these products are not high, ranging from 30 to 60 euros. We recommend using them with a thermostat.

Do you have no idea which to buy or where to buy? These below are the models selected and recommended, as they perform their function properly.


The thermostat is a small electronic device useful for managing the temperature inside the greenhouse. If we have a heating element for our seedbed, it will be essential to provide us with a thermostat. Why? The answer is simple. In this way we can set the minimum and maximum temperature that must reach our greenhouse, for example: minimum 18 ° – maximum 24 °. So, as soon as the temperature inside the greenhouse drops below 18 degrees, the heating is activated and when it reaches 24 degrees, it switches off automatically. We will save electricity and we will not risk reaching temperatures too high, harmful to small shoots. Yes, because a mat that is always in use can reach a temperature of over 30°C inside the seedbed.

It is an accessory that we will hardly find in a greenhouse. But there is no need to worry, even here the prices are not high, ranging from 25 to 50 euros.

Which one to buy? Simple, these listed below are absolutely the best in quality and price. Simple to use and performing their function properly. Attention, if you choose to buy the thermostat in the picture above, if necessary, you will have to replace or adapt the socket, to connect us for example, a greenhouse with siemens socket.

Ambient Humidity

Keeping a high level of humidity in the greenhouse is important for the germination of the seeds themselves. Moisture makes it easier for small shoots to irrigate, because the roots still fail to develop and cannot be drawn into the substrate. Moisture in the seedbed will be obtained by keeping the potting soil constantly moist and with heat inside. It is, however, important to keep the cracks in the lid open, in order to facilitate the exchange of air inside the greenhouse.

Unlike other sites, I do not consider it appropriate to use, at the same time recommend, any device or accessory that controls the percentage of moisture inside the seedbed. This is because it would require the expense of other money. Because most of the readers are passionate about the sector and amateur gardeners, at their first experiences, who try to have the satisfaction of their flowering garden, with the plants cared for in their own way, from the beginning.

Indoor Led Lamps

Light will be crucial as soon as the first shoots emerge from the ground, not before. In fact, you can place the seedbeds wherever you want without worrying about the light so that the first two leaves do not appear. So it is good to check the greenhouses constantly, as soon as some seed is born can stay in the greenhouse a few more days, but not too long. After two or three days, the small plant will need 18 hours of light and 6 hours of darkness to develop and grow. So how do you do it?

The cheapest solution is the window, even if it is not the best one for the many against. For example, one of these is that during the months of February and March, the days are not so long as to ensure 18 hours of light to the plant. That of the house? The answer is no, the plants require a certain type of lighting to grow. Often the right intensity does not come from the window, the shoots may stretch and bend towards it, in search of more light. So the solution that I personally recommend is to get a grow lamp suitable for growing at home (indoor). These are special lamps that artificially reproduce sunlight. There are many on the market, differing from cost to power. With 30/40 euros or more, you can buy a grow lamp that does its job well. Now you’ll ask yourself: but the consumption? Don’t worry, they are LED lamps, so most of them consume very little!

Below you will see the lamps that we recommend based on quality and price. Obviously you have to choose considering the amount of plants available and the space they occupy. Considering also that, the more watts they are, the more powerful will be the intensity and the ray of light. They should be placed at a certain distance, just follow the advice of the seller or the leaflet.
