Speed up seedlings with the best heated propagator

We like this Stewart propagator for its versatility. Measuring in at 52cm long and 42.5cm wide, this gives you options as to how you use the space. You could fill the base with compost and sow seeds directly, or you could fill this with flexible combinations of pots and seed trays if you want to propagate different plants.

The rigid thermoform lid is completely transparent for good light transmission to encourage photosynthesis and healthy growth. The 22-watt heating element in the base of the unit will generate a steady level of heat, while the two vents in the lid will help you manage humidity and airflow.

This heated propagator is basic, a simple grow box with an eight-watt heating element, but it's perfectly capable of giving all kinds of vegetable and flower seeds, seedlings, and cuttings a warm start in life.

This particular propagator measures 38cm long, so it can fit a few pots or seedling trays, and features simple on/off operation, so you can choose when to activate the heating element by turning it on from the mains. Temperature control also comes in with the single ventilation vent built into the lid of the box to regulate airflow.

Adding light into the mix makes for even more optimal growing conditions for all kinds of plants, from peppers to petunias. This tidy set from Erogeen gives you four seed bays, each of which feature their own adjustable LED lighting, and a heat mat that sits beneath them.

There are five adjustable brightness settings and four timing settings; four, eight, 12 and 18 hours, so you can make the growing conditions perfect for the seeds that you're germinating. This comes complete with 10 plant-label stakes and two small-scale gardening tools.
