Multi Duct 8ft Double Complete
Multi-Ducts are high-yielding complete hydroponic growing systems which enable growers to manage a large number of plants from one low-lying integrated reservoir – dramatically up-scaling the number of plants and yield, without increasing workload. Each Multi-Duct has long planting channels above its low-lying reservoir.
Plants are placed in rockwool blocks onto the channels and the roots grow along the channels where they have unrestricted access to oxygen. Nutrient solution is constantly pumped up from the reservoir to the ‘channel’ and flows over the roots of the plants. Whatever the plants don’t use drains back into the reservoir ready to be passed over the roots again and the solution in the reservoir is emptied and replenished every 2-3 weeks to maintain a perfect balance of essential nutrient elements.
The constant supply of water and nutrition to the roots combined with unlimited access to oxygen means growers find that plants are healthier, faster growing and produce up to 3 – 4x more yield than if growing using traditional soil methods.
The NFT 6FT Multi Duct Double Complete gives all the usual advantages of the ever reliable NFT hydroponic method, but on a much bigger scale. This is two 6ft tables complete set on a 190 litre tank. Our 6ft Multi Duct double complete comes with 2 x Kit Bags meaning that you will receive 2 x MJ1000 pumps not 1, this means that the flow rate is not compromised
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.
