Sankey Grostart Midi Unheated Seed Propagator | 38cm, Adjustable Vent

Start seeds and root cuttings with a reliable unheated propagator design that creates a steady, enclosed microclimate without added power. The 38cm midi footprint gives you generous space for sowing and raising multiple seedlings at once, while the clear high-dome cover helps retain moisture and lets light in for strong early growth. An adjustable side vent enables precise humidity and temperature control, helping compost stay evenly moist and supporting healthy germination. The easy-view lid makes it simple to check progress without disturbing delicate seedlings, and the raised cover height allows taller young plants to develop before potting on.

• Unheated microclimate for seeds and cuttings
• Adjustable side vent for humidity control
• Clear high-dome lid boosts light and moisture
• 38cm midi size for multiple seed trays’ worth
• Stable base keeps watering tidy on windowsills

Built for season-after-season propagation use, the reusable, easy-to-clean design suits windowsills, shelving, and greenhouse benches where consistent compost conditions matter. Use it for vegetables, herbs, flowers, and houseplant cuttings to reduce moisture loss and improve early-stage success, especially when indoor heating or dry air can stall germination. The contained base tray helps keep growing media in place and makes routine watering neater, while the vent gives you day-to-day control as seedlings transition from sprouting to sturdier growth.
