Introduction: My Indoor NFT Hydroponics System

This is a short slideshow for a NFT hydroponics system I built. This system uses the Nutrient Film Technique to grow plants without soil. Instead, the nutrients are delivered via a recirculating stream of solution that is driven by a water pump.

If you've read about my other DWC Hydroponics System, you'll notice many similarities in the construction and building materials. In my experience, CPVC pipe and fittings are an excellent way to construct light-duty frames and has a high potential for modularization.

The system has since been scrapped because of a need of the materials for another project. Even though it won't be completed, hopefully there is enough detail in this slideshow to give you some ideas and information.

    Does the water has to circulate endless during the whole period of growing the plant? how Do I know when to turn on or off the Pump?

    awesome!

    can you please give me all the materials needed? id love to have this in my little apartment!

    I like this system

    Which system performed the best?

    Can you tell me how you anchor the florescent lights? How does the chain keep secure wrapping around the center cross-piece?
    TIA

    Hi, All that is securing the fluorescent light fixture to the frame is the chain wrapped around the center cross piece. The fixture is very lightweight and it only takes about three wraps to get enough friction to hold the light in place. I've only had this unit in operation for a few months before it was scrapped but in that time the chain has never slipped off of the pipe. Thank you for your question.

    How much energy are you using to run the lights?

    That looks like a 4 foot, T12, 80 watt fluorescent fixture which, if run 16 hours per day, will use about 1.3 kilowatt-hours or 39 kilowatt-hours per month, per fixture. Use T8 or T5 fluorescent fixtures, or LED fixtures for higher efficiency. Be sure to use full spectrum daylight bulbs and reflective/white surfaces around your system.

    the downspouts are a really good idea! i have used 3" and larger pvc for this same style but im sure the downspouts are much less expensive if you have to purchase them. Do the florescent put out enough light to grow crops all the way to fruit? I have had difficulty getting large type plants tomato beans etc to grow strong with them only, any tips?
