Samuel Alexander 4 x 38cm Unheated Seed Starter Tray Grostart Midi Propagator Indoor Seedling Planter

Designed for low-temperature growing, the Samuel Alexander Grostart Midi unheated Seed Starter Tray helps create a protected, enclosed environment for germinating seeds and rooting plant cuttings indoors. Similar to a mini greenhouse, it supports controlled conditions that can be used all year round, whether you’re starting fruit, vegetables or herbs from seed, or giving cuttings a head start while kept inside during the winter period.

With a compact footprint suited to windowsills, it’s an easy way to organise early-stage growing at home while helping shield young plants from the elements. This set is also well suited to anyone looking for a simple, hands-on activity to enjoy together as a family.
