Stewart P035B Essentials Electric Propagator, 52 cm - Black

Product Information

Made in the UK with robust and durable shatterproof lids, it’s ideal for novice gardeners as it’s self-watering. 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?

Stewart Heated Propagator - 52cm | Homebase

Optimal soil temperature for germination is 10 – 15°C so the propagator needs enough power to maintain this. A simple to operate system that gives your seedlings the light, protection and heat that they need for perfect growing conditions. Whether you’re starting seeds off in these cold, winter months, encouraging cuttings to root or raising tender plants originally from warmer climates, a heat source will help create the best conditions to nurture them. As a rough guide, large, one-cell propagators of around 50 x 45 cm will house approximately 140 seeds ; however, they won’t fit on all windowsills. However, the good thing with individual-cell propagators like this is that you can have better control over the temperature in each cell.Non-native fruits and vegetables such as tomatoes and peppers aren’t used to UK climates and require much more warmth than we have to offer. Having an idea about the length of the propagator’s mains cable before purchasing is also a good plan. Thanks to their bottom heat and high humidity, heated propagators can also be instrumental in helping cuttings to take root.

Sarah’s role as chief editor at DIY Garden is about more than just making sure we’re literally dotting the i’s and crossing the t’s (although she’s a stickler for detail, so it’s certainly about that too! My testing took place in early January (just to give a bit of seasonal context) and within 3 days the peas had started to germinate. Until we get there though there’s a heated mat which works at 15C above the ambient temperature to help plant germination and growth.

For example, the Garland Super 7 Propagator is one of the best heated electric propagators for catering to different seeds; it has seven different pods and each one has its own ventilation.

The propagator features a durable plastic tray which when in operation keeps plants between 15 and 20℃.

Position it on a flat surface; a windowsill out of direct sunlight is a good spot, but make sure the dimensions of your chosen propagator are a good fit. Large, one-cell units that measure around 52 x 45 cm can be used to try to germinate around 140 seeds. The Garland Fab4 Electric Heated Propagator is a great option for those requiring a little more warmth as it boosts the soil temperature by up to 10°C.

It comes with a 13W carbon fibre element that provides an even heat distribution, raising the temperature by around 8°C. Taking the temperature readings and opening the vents, or even turning the unit off for a brief time, is the only way to control the heat. Once the whole thing becomes saturated, the water slowly evaporates into the cells sitting on top, and therefore waters your soil. Obviously the heat it generates is very subtle, but I still found myself putting my hand on the side of the unit to check it was on when I first set it up.If you want to ensure a high yield of germinated seedlings, this 22W Stewart P035B Electric Propagator allows you to plant up to 144 seeds at a time, which can result in germinating at least 50 plants in one ‘round’. This heated propagator is designed to fit on a windowsill, and has a single deep tray that can either be filled directly with soil or pots, which is a useful feature when you’re growing your own.
