Frequently Asked Questions

How much does it cost?

The Starter Kit is $128 and includes everything to get going. Expansion Kits are $93 each. Shipping is a flat $19.99 on all orders, regardless of quantity.

Is it beginner friendly?

Yes — it’s very easy to set up and use. If you can fill a reservoir and plug in a pump, you can grow like a pro. No timers or electronics to program.

Can I leave town with this system running?

Definitely! That’s one of the biggest perks. Just make sure your reservoir is full before you go. No more coming home to dead seedlings or trying to train someone to water properly.

How does the system work?

Water is pumped from a reservoir into a water channel below a large flat area holding a capillary mat. One end of the mat sits in the water channel, wicking water evenly across the mat. Plants sit on top, and their soil draws water up through drainage holes to keep them hydrated automatically.

How many trays can be linked together?

For our farm We currently have 20 trays linked successfully but have not reached a limit yet. The system supports vertical or horizontal expansion as big or small as you need.

Can it fit on multi-tier shelves?

Yes! The Seedwell Tray system fits well on 3-6 tier shelves. Shelf depth recommended is 20"–24", with a minimum of 18" footprint.

Does it work with soil blocks or mesh trays?

Yes! Soil blocks work well directly on the capillary mat, and on mesh-bottom propagation trays. Soil blocks stay 100% hydrated.

Can heat mats be used with the system?

Yes, heat mats work underneath the capillary mat and transfer heat effectively. Be sure to use the heat mat according to the manufactures specifications and use a waterproof mat without rips or tears.

How often should the pump run?

The pump can run 24/7 to keep water fresh, costing around $4.90 per month on average in electricity (40w Pump). Running it on a timer intermittedly is not recommended but can be achieved.

Can I use fertilizer in the system?

You can use diluted water-soluble fertilizers. Avoid fish emulsion directly in the water to prevent odors.

How often should I clean or replace the capillary mat?

Mats typically last multiple seasons. Clean them at the end of each season by rinsing, soaking in a bleach solution, sun-drying with roots side up, then brushing off roots before storage.

Is the system easy to disassemble and clean?

Yes. The system breaks down easily by loosening two hand-tightened nuts per tray and sliding out the piping. Clean tubing and trays with sanitizing solution before storing.

Does it prevent over-watering or under-watering?

Yes! The system maintains consistent moisture, eliminating guesswork and significantly reducing root rot and soil erosion. Plants grow faster with reliable hydration.

Do seeds germinate faster?

In personal tests, seeds on the Seedwell Tray germinated faster and more consistently compared to outdoor germination.
