However, most users find this level of control more than enough for most seedlings, and appreciate its ease of use. Despite having seven cells, it has a compact design enabling you to grow germinate multiple seed varieties in one go. Some popular flowering plants such as dahlias, sweet peas, begonias and petunias are usually started off in early January too. The idea of adding a propagator to your house might seem daunting – doesn’t it cost a lot of money to have a heat source on for a long time? Large, one-cell units that measure around 52 x 45 cm can be used to try to germinate around 140 seeds.

Optimal soil temperature for germination is 10 – 15°C so the propagator needs enough power to maintain this. They’re often big enough to fit 2 x 24-pot seed trays, and if you get 3 seeds in each pot, this can mean the potential to plant 144 seeds. This unit consists of a heated tray with a ventilated plastic lid – you supply your own trays/pots, but it can fit 2 x 24-pot plant trays, so that gives you a good idea of its size in practical terms.A propagator is like a mini greenhouse and is more than adequate for most small scale growing needs. This makes them suitable for those who want to grow a small amount of each plant, although the trays are still deep enough for your plants to develop strong roots.

However, for its reliability, warmth and simplicity, this propagator remains a very good value option for those without a sunny window ledge. If there are separate trays, or there’s enough space to use your own pots, you can have a lot more flexibility on using different compost types and planting different seeds. For the more ambitious grower, there is the option of multiple units, such as the 3 tray windowsill propagator set and there are also height extension kits for taller growing plants. Many users found that it got too hot for some seedlings, so I’d recommend keeping an eye on things for the first few days. It would have been nice to have some kind of indicator light on the unit so you know when it’s on or off.Non-electric propagators are a lot cheaper than a heated propagator, but without the extra, regulated warmth and bottom heat that you get in a heated propagator, growth will be slower and less consistent. This generously-sized propagator has plenty of space and its extra high, clear lid allows excessive moisture and warm air to be released via two vents. Whether you're hiking through colorful forests, jumping in puddles, or strolling through pumpkin patches, our wellies are your go-to choice for staying dry and comfortable. Once the whole thing becomes saturated, the water slowly evaporates into the cells sitting on top, and therefore waters your soil. The thermostat has to be fed in via the green adjustable vents and won't fit through the small holes in the side panels as seen in the demonstration video.

Once the seeds have germinated and are beginning to grow, you can either remove them from the propagator or just unplug the unit if all the seeds have germinated. It’s slightly warmer than others on the market, producing good results especially for seeds that require a hotter climate. This sort of height will give a lot of flexibility on the types of seeds and cuttings you can propagate in the unit.Plus, if you get a propagator with a thermostat, it will regulate the temperature and save energy by turning off when it reaches a certain temperature.
