Propagators — mini greenhouses for sowing seeds and rooting cuttings: tall models with adjustable ventilation, with drainage holes, and self-watering, from the Garland brand. They maintain stable humidity and temperature, which are key for even germination. Thanks to the transparent dome, they create a microclimate conducive to sprouting and reduce water loss, significantly shortening the waiting time for the first seedlings. Shipping available throughout the EU.
In this category, you will find propagators suited for various scales of cultivation — from a home windowsill to larger sowings. To speed up germination of heat-loving species, combine the propagator with substrate heating using the heating mats offer, and find your seed material in the seeds section.
How to choose a propagator? Size and ventilation
The choice of propagator mainly depends on the scale of sowing and the target height of seedlings, so it’s worth planning how many pots and how tall plants you want to grow under one dome. Tall propagators with adjustable ventilation are the most versatile and come in several sizes — the small model is suitable for a windowsill and small batches, the large can accommodate more pots, and the very large is designed for intensive sowings and taller seedlings. Adjustable ventilation holes allow you to gradually reduce humidity and prevent plant overheating as they grow. Propagators with drainage holes, like the Super Size model, facilitate excess water drainage and reduce the risk of overwatering and root rot. The self-watering solution self-watering with 7 mini greenhouses maintains humidity longer and organizes simultaneous cultivation of different species in separate compartments. When choosing the size, leave seedlings some space above the substrate so leaves don’t touch the dome and have room to grow freely. If you’re just starting with sowing, choosing a version with adjustable ventilation gives the greatest control over conditions and is easiest to adapt to the plants’ development stages.
Ventilation, drainage, and self-watering — what you’ll find in this category
Individual models differ in how they manage humidity. Adjustable ventilation in tall propagators allows smooth control of the microclimate — from fully closed during germination to wider opening during hardening off. Drainage holes, present for example in the Super Size model, protect roots from excess water.
Self-watering versions reduce watering frequency and maintain stable conditions even during several days of absence. The self-watering with 7 mini greenhouses solution allows growing several species simultaneously in separate compartments.
Garland brand
Garland is a British manufacturer of gardening accessories valued for durable, well-designed propagators and mini greenhouses. Equipment from this brand stands out with solid domes, thoughtful ventilation, and resistance to years of use, which translates into consistent sowing results. More practical tips on plant propagation can be found in our gardening guide.
How to use a propagator — basics
Humidity and ventilation — keep the dome closed during germination, then gradually open ventilation holes after seedlings appear to reduce the risk of fungal diseases.
Bottom heat — for heat-loving species, place the propagator on a gentle heat source, such as a mat from the heating mats offer, to speed up and even out germination.
Light — after germination, provide seedlings with bright, diffused light, avoiding direct strong sunlight through the dome.
Hardening off — before transplanting, gradually acclimate plants to outdoor conditions by opening ventilation wider and shortening time under the dome.
Frequently Asked Questions
What size propagator should I choose?
Choose according to the scale of sowing and seedling height — small for a windowsill, large and very large for more pots and taller seedlings.
Is adjustable ventilation necessary?
Yes, adjustable holes allow you to control humidity, reduce plant overheating, and smoothly transition to hardening off seedlings.
Can a propagator be combined with a heating mat?
Yes, bottom heat speeds up and evens out germination, especially for heat-loving species. Check the heating mats section.
Who is the self-watering propagator for?
It’s ideal for those seeking stable humidity and less frequent watering, including during several days of absence.
Do you ship to the EU?
Yes, we ship propagators to all countries in the European Union.
