Garland 24 Cell Self-Watering Seed Success Kit – Capillary Seed Propagator

Take the guesswork out of seedling moisture with the Garland 24 Cell Self-Watering Seed Success Kit, a reusable propagation system designed to maintain a more consistent supply of water during germination and early plant development.

Instead of repeatedly watering each individual cell from above, the Garland system uses an internal water reservoir and capillary matting. The 24-cell growing tray sits above the reservoir, allowing moisture to wick upwards through the matting and into the growing media as required.

A clear propagation cover helps retain warmth and humidity during germination, while the generous 24-cell capacity provides enough space to start multiple varieties of vegetables, herbs, flowers and other suitable plants in one compact unit.

How the Self-Watering System Works

The clever part of the Garland Seed Success Kit is underneath the growing tray.

The system consists of:

Water Reservoir → Support Platform → Capillary Matting → Growing Media → Plant Roots

Water is stored in the bottom reservoir.

Above this sits a raised support platform covered by capillary matting. One end of the mat extends down into the water reservoir, allowing it to continuously wick moisture upwards.

The base of each growing cell contacts the damp capillary matting, allowing moisture to move into the growing media.

This gives seedlings access to moisture without relying entirely on repeated overhead watering.

24 Individual Growing Cells

The growing tray contains 24 individual cells, providing an organised way to propagate multiple seedlings simultaneously.

Each cell measures approximately:

5cm × 4.7cm × 5.8cm deep

with a capacity of approximately:

0.1L per cell

Individual cells make it easier to keep seedlings separated during early development and simplify transplanting once plants are established.

Ideal for Starting Seeds

The Garland 24 Cell Seed Success Kit can be used to propagate a broad range of suitable plants, including:

• Vegetables
• Herbs
• Flowers
• Ornamentals
• Annuals
• Perennials
• Suitable indoor plants

When planting multiple varieties in the same tray, group seeds with similar temperature, moisture and light requirements together.

Clear Propagation Cover

A clear cover sits over the 24-cell growing tray during germination.

This helps create a protected propagation environment by retaining:

• Humidity
• Moisture
• Warmth

The transparent construction allows natural light to reach the growing area while making it easy to monitor germination.

Once seedlings emerge, Garland recommends removing the clear cover.

Up to Approximately 7 Days Between Reservoir Refills

According to Garland's instructions, a full reservoir can provide water for up to approximately 7 days, depending on growing and environmental conditions.

Actual water consumption will vary according to:

• Temperature
• Humidity
• Plant size
• Growing media
• Light levels
• Air movement
• Number of active seedlings

The reservoir should therefore still be checked regularly rather than simply being left unattended for a fixed period.

Reusable Propagation System

Unlike lightweight disposable seedling trays, the Garland system is designed to be cleaned and reused.

After transplanting your seedlings, the components can be cleaned and stored ready for your next propagation cycle.

This makes the kit suitable for growers who regularly start crops from seed throughout the year.

What's Included

The Garland 24 Cell Self-Watering Seed Success Kit is a five-piece propagation system containing:

• 1 × Water Reservoir Tray
• 1 × Raised Support Platform
• 1 × Capillary Mat
• 1 × 24 Cell Growing Tray
• 1 × Clear Propagation Cover

Growing media and seeds are not part of the standard G165 kit.

How to Set Up the Garland Seed Success Kit

Step 1 – Fill the Growing Cells

Fill each of the 24 cells with appropriately moistened seed-raising compost or propagation media.

Firm the media sufficiently to ensure the bottom of each cell will make contact with the capillary matting.

Step 2 – Wet the Capillary Mat

Thoroughly moisten the supplied capillary mat before installing it.

Step 3 – Position the Mat

Place the capillary matting over the support platform.

Allow the extended end of the mat to hang down into the reservoir.

This section acts as the wick that draws water from the reservoir.

Step 4 – Fill the Reservoir

Place the support platform into the reservoir tray and add water.

Step 5 – Install the Growing Tray

Position the 24-cell growing tray on top of the capillary mat and support platform.

Make sure the growing media at the bottom of each cell is contacting the matting.

Good contact is essential for effective capillary watering.

Step 6 – Sow Your Seeds

Plant seeds according to their individual packet instructions.

Each growing cell is designed to ultimately support one plant.

Step 7 – Water from Above Initially

After sowing, thoroughly water the growing media from above.

This establishes good moisture contact between the growing media and capillary matting so the self-watering action can continue effectively.

Step 8 – Fit the Clear Cover

Position the clear cover over the tray during germination.

Step 9 – Remove the Cover After Germination

Once seedlings emerge, remove the clear cover to provide the young plants with appropriate growing conditions.

Maintaining the Capillary System

The capillary mat should remain damp while the self-watering system is operating.

If it completely dries out, thoroughly re-wet the mat to re-establish capillary action.

If the growing media becomes excessively wet, Garland recommends temporarily removing the capillary mat to allow the media to dry.

The growing tray should also be lifted away from the mat once or twice per week to help prevent developing roots from growing into the capillary material.

Light Requirements

Position the propagator somewhere that receives plenty of suitable light.

Possible locations include:

• Bright windowsills
• Greenhouses
• Propagation benches
• Indoor growing areas
• Under suitable propagation lighting

Avoid excessively strong direct sunlight while using the clear cover, as temperatures inside a covered propagator can rise rapidly.

Germination Temperature

Garland advises that many seeds germinate successfully at growing-media temperatures of approximately:

19–23°C

The exact optimum temperature depends on the plant species being propagated.

A suitable propagation heat mat can be useful where ambient conditions are too cold, but temperature should be monitored to prevent overheating.

Easy Seedling Removal

The support platform has another clever use when it's time to transplant.

Once seedlings are established:

1. Remove the growing tray.
2. Turn the support platform upside down.
3. Position the growing cells over the raised pegs.
4. Use the pegs to help push the individual root plugs upwards.

This assists with seedling removal and can make transplanting easier than trying to pull young plants directly from the tray.

Cleaning & Reusing the Kit

After use, remove growing-media residue and wash the components thoroughly.

The reservoir tray and growing tray can be cleaned in a dishwasher on a cycle below 50°C.

The support platform and clear cover should not be placed in the dishwasher.

The capillary mat can be cleaned separately according to Garland's care instructions.

Store the cleaned system away from direct sunlight when not in use.

Product Specifications

Why Buy the Garland 24 Cell Self-Watering Seed Success Kit?

Getting seeds to germinate isn't usually difficult because of the seed tray itself. Maintaining the right balance of moisture, temperature and humidity is often the bigger challenge.

The Garland system addresses one of those variables with a simple passive watering design.

Its reservoir supplies the capillary mat, while the growing media draws moisture upwards through contact with the matting. There's no pump, timer or electricity required for the watering system.

The clear cover provides a useful germination environment, while the 24 individual cells keep young plants organised until they're ready for transplanting.

Most importantly, this isn't designed as a disposable one-crop seed tray. The reusable components can be cleaned and prepared for the next propagation cycle, making it an excellent addition to a permanent seed-starting setup.
