The fact that the nutrient film technique hydroponics many benefits soil different culture, but the biggest is that the root system of plants constant access to oxygen and that the plants have access to as much or as little water as they need, this is important because one of the most common mistakes when grown under irrigation and hydroponics prevents this from happening, so that large amounts of water can be made available to plant roots and water, are not used simply discarded, recalculated, and then added waters, so that anoxic conditions can lead to problems in the root systems.
In soil, a producer must be very experienced to know exactly how much feed plants, the plants are not too many and will be able to access oxygen, too little and the plants will be the ability to transport nutrients to lose, usually moved in root, while in the solution.
To make your own NFT hydroponics system
One of the biggest mistakes "are not the only one who though" user-oval ducts in your home-made system, which by the nature of this system is to a film of water "between 1mm and 3mm" on a Free wide area, so you can see, using a circular water channel is somewhat pointless.
As you can imagine, using a squire gully makes life much easier, because finally task light proofing your water channel, other funds already provided, what is left is taken at the end form and a number of holes cut for your plants to grow, a way for the nutrients back to your nutrient recalculate
My NFT hydroponics system used in my greenhouse I built as a vertical hydroponics NFT system, if the space is very limited, although I managed to get every inch exploit available, and 68 fixed seats for my plants and only Half of my greenhouse, with ample space for more on the same page to add channels.
Make your hydroponics NFT system is watertight, but as being able to delete channels from a homemade hydroponics NFT system is easy enough, until you consider how little one.
If your water may only be 1mm to 2mm depth in the water channel channel, so any lip-edges must be as flat as the bottom of the trench, each additional level increases the depth of the water and cause drastic some water logging on the far end.
• NFT Water Pump for large / heavy
Using the correct water pump is also very important to wear this for large / heavy, it will mean that you need to control the flow of your tank, so the pressure will be put on the pump and simultaneously reduce your nutrient solution heat also Max temperature of the water solution is 21c a warmer and nutrient lockout will take over, and some algae can grow.
• NFT Water Pump for small / underpowered
Depending on high or distance from your water supply solutions must travel, take my vertical hydroponics NFT system, such as the height at which water must travel is two meters, so a 1000 liters per hour water pump is just right for the job, with a Horizontal NFT hydroponics growing system got hold of a pump that is too small for the small vertical Hamelin management is difficult, as I have spent a bird bath fountain pump, but I can not recommend these pumps are not very cheap and break even more than most pumps.
• NFT WATER TANK
Choose a tank that is no higher than your lowest Gully, and of course it is necessary to be secured to the gently sloping algae and large enough for many nutrient enriched water.
Because NFT hydroponics systems are so sensitive to the pumps and other errors, I use felt soak used in bench top grows to excess water to absorb and help stop plants from falling over, as roots grow into the feeling side of carpets and NFT systems are ideal for a fail-safe when placed in the bottom of the NFT channels will help dry patches that are created when the roots grow in the growing channels, whose roots grow eliminate certain restriction of the water as good solution, and certainly felt this would help with the damming and also problems with the pump.
• NFT hydroponics homemade medium "TOP TIP"
You probably have noticed from looking at other NFT hydroponics homemade system configurations, square cubes rock wool is mainly used, but if my NFT system is homemade, I tried to keep costs low as 70 Rockwood cubes would have cost a few pounds. to avoid this charge, my alternative Earthwolf zero emission ceiling insulation, diffusion 8SQ meter covers, so I think that's enough for my pots to fill and the best part is that the hole roll cost me five pounds of my local hardware store.
• Remember
All wool fiber has a high pH, which, if not balanced with your hydroponics nutrient solution pH on use, it will throw you off your hydro fertilizer awake, "more than 6.5", then immersed in a aqueous solution of pH 3, overnight in a bucket first and then press the excess water before installing.
Pots and pans that I've made NFT gullies, all PVC pipe that is 40mm drain pipe to length, plus a little extra, I can pull out the pot if needed, oh yes a small slot that lets the water under the pans easily Earthwolf zero emissions ceiling insulation is very loose / light, and my opinion is better than the bought cubes that you can decide how fluffy you need for your media, and also mixed with other hydrothermal growth media if you wish.
If you try these PVC pipes hydroponics pots Earthwolf zero emission ceiling insulation, you must earthwolf to rather close, so it is nutrient-rich water flooded rock wool solution.
You can also use rock wool slabs, rock wool slab and cut plastic take or cut, make it this way would also keep costs down.
• Adhesion YOUR HYDOPONICS homemade NFT system together
Selecting the right glue to hold the NFT systems waterproof and waterproof PVC pipe to keep, and you have a few options I've tried both and each works well, utility room / bathroom / kitchen, silicone is easy to use, or PVC pipes and gutters are also very good for you whoever you are, you should easily wipe the surface where sealing is some sandpaper to ensure good conductivity.
