AquaMat Capillary Mat Systems

Water enters the AquaMat and spreads across the capillary surface. Containers with bottom openings sit directly on the mat and absorb water from below, allowing moisture to move upward through the growing media.

With a Blumat control option, the ceramic sensor responds continuously to moisture conditions and opens or closes the water supply automatically. The surface-mounted sensor reads the mat directly; the preset 5" sensor uses a soil-filled pilot container to regulate the mat.

• 2×4 ft — Compact propagation or vegetative area
• 3×3 ft — Square grow-tent or nursery layout
• 4×4 ft — Full 4×4 grow-tent footprint
• 4×8 ft — Large propagation, nursery, or vegetative area

• Preset 5" Blumat Sensor — Sits in a soil-filled pilot container and regulates flow according to root-zone moisture. Best for pots approximately 4" or larger.
• Surface-Mounted Blumat — Uses a bell-shaped ceramic base that sits directly on the mat and controls moisture across the capillary surface. Ideal for cell trays and small containers.

• Grassroots 1-Gallon Bottomless Sleeves — Open-bottom containers that maximize contact with the mat, improve aeration, and simplify transplanting. Includes 10 for 2×4, 20 for 3×3 or 4×4, and 40 for 4×8.
• Non-Woven Nursery Pots — Biodegradable, tear-resistant fabric containers that allow roots to grow through the sides and bottom. Includes 50 with any mat size.
• None — Use your own containers. Choose pots, trays, or bags with drainage openings positioned flush against the mat.

• AquaMat capillary mat sized for your selected growing area
• Blumat irrigation control components for the sensor you select
• Grassroots bottomless sleeves or non-woven nursery pots when a container option is selected

Automated AquaMat configurations require an 8mm supply line and a compatible water source:

• 8mm supply line running from the water source to the Blumat control
• Gravity reservoir with an 8mm bulkhead connection, positioned high enough to provide reliable operating pressure
• Pressurized source such as a hose bib or pump, paired with a Blumat-compatible pressure reducer

The water source, main supply line, pump, hose connection, and pressure reducer are sold separately.

• Install the mat on a clean, level surface so water can spread evenly.
• Place containers directly against the mat with no air gap beneath them.
• Use containers with bottom openings that allow the growing media or roots to contact the capillary surface.
• Top-water newly placed containers until moisture contact is established between the growing media and the mat.

What is an AquaMat capillary mat system?

It is a bottom-watering system that spreads water across a capillary mat so compatible containers can absorb moisture from below.

Which Blumat control should I choose?

Choose the preset 5" sensor for soil-filled pots approximately 4" or larger. Choose the surface-mounted Blumat for cell trays, small containers, or when you want the sensor to read the mat directly.

Can I use my own pots?

Yes. Select “None” for the container option and use pots, trays, or fabric bags with openings that sit flush against the mat.

Can AquaMat run from gravity or pressure?

Yes. Automated configurations can run from a properly elevated gravity reservoir or a pressurized source fitted with a compatible pressure reducer.

What is sold separately?

The main 8mm supply line and water-source components are sold separately.
