Multi-Duct NFT Systems

multi-duct nft systems

Multi-Ducts are ideal if you’re growing on a larger scale. Grow up to 48 plants without media!

They work the same as a Gro-Tank NFT System, but give you the space to grow a higher number of plants.

For anyone looking to maximise the size of their crop, we can’t recommend Multi-Ducts highly enough

No more hauling bags of media around!

Just place young plants into the Multi-Duct when the roots are showing on the outside of the soil or rockwool block.

Don’t add any more soil, the roots will grow directly into the stream of nutrient solution which is constantly pumped around the hydroponic system. The run-off flows back into the reservoir.

Growth is fast, productive and healthy because the plants take up whatever they seed, never too much or too little, and there’s no soil to restrict root access to the water, nutrients and oxygen.

Switch to NFT and you’ll never switch back!

why they are great

Perfect for growers who want to:

  1. Use less media
  2. Grow tall plants in a low space – so need a low-level system
  3. Get used to one system and scale up to larger systems over time – available for up to 120 plants

instructions

Set-up instructions for Multi-Ducts systems

hints and tips

Ensure plants are well-rooted before they go into the system. The starter media should be covered in white roots.

Spacing – as a rule of thumb 1 plant per square foot. This can be increased or decreased depending on plant variety.

Leave the pump running constantly.

Start plants in either in either 3” or 4” rockwool cubes 3” / 4” pots filled with soil or coco 3” net pots filled with clay.

If using rockwool cubes completely remove plastic wrapping from the cubes.

If moving from pots to the Gro-Tank remove the plants from the pots so the roots can access more oxygen.

All but the smallest of plants will need additional support, i.e. yoyo’s or pea netting.

Set the flow rate on the pump so that the nutrient solution moves over the spreader mat constantly, but not so much that the roots are submerged.

Cut lengths of spreader mat long enough to allow an overhang of a few inches from the tray into the tank.

Plants under lights will take up water at a faster rate than they take up nutrient which means the EC will rise over time. 

Top up the tank with half strength nutrient solution, check EC and add extra nutrient if required.

Then adjust pH level and perform a solution change every 2-3 weeks to keep the pH and EC balanced.
