This is my newest verticle hydroponic system built to grow lettuce for restaurant and farmers market sales. It uses Crop King NFT (nutrient film technique) channels spaced horizontally on an A-frame to provide optimum water, oxygen and nutrients to the roots of each plant. The plants seem to be doing very well with 2 400 watt metal halide grow lights. The current setup can grow 270 perfect heads of lettuce a month. thelettucepeople.com FaceBook: The Lettuce People Video Rating: / 5 Related PostsLED vs T5 NFT Hydroponic System Trial Update by The Lettuce PeopleLED vs T5 in Vertical NFT Hydroponic System by The Lettuce PeopleLED vs HID Indoor Grow Trial by The Lettuce PeopleIndoor Hydroponic Lettuce Farm, The Lettuce PeopleFollowup – Hydroponic Rail System for Growing LettuceHow to Make a Mini Kratky Hydroponic System for Lettuce

    I was wondering why you decided to do the setup this way. instead of putting the two blocks back to back, making it an A frame, and that would also solve the problem of the top rows getting ample light?

    плюс в том что вода не зацветет, но все равно слишком затратно.

    great job! nice innovation! keep exploring and sharing please!

    So how did the system work?  Most importantly was the one light adequate.  We are growing vertically in multi level towers, but it takes a lot of light fixtures.  Hoping to cut back on light need.  Thanks.

    what size reservoir is that?

    Does the water have to flow all day and night ( 24/7 )?

    So this might sound dumb: I've seen a few of these A frame designs out there. Why couldn't you just put all of your troughs on the ground next to each other and still have the same footprint?

    That system is cute in a major way …. but does it work?

    Awesome Setup ! Nice and detailed explanation, would be doing a similar setup soon for lettuce .

    Hi there, How much difference in flow rates are you getting between the top level and the lower? How much did you plan and mitigate for this?
    Nice clear video,
    Thanks

    You can also get a heat gun and warm up the end of the downspout and bend the end in a way where water won't leak. It's pretty easy. It shouldn't take you more than a minute per end. It's similar to pinching the end of a paper towel tube. If you have longer channels instead of 10ft channels, there are downspout connectors available. Instead of sealing the ends, you'll just connect them like legos. 

    If you want it 100% seal, then add a large bead of silicone, but there's no point since it's a NFT system, and you're only going to have low level of water.

    Love the cropking setup, but for large expansion, don't you think they get pretty expensive? To cap the end of the downspout, I was thinking of using regular foam and sealed with silicone. They sell large ones in homedepot. 
    It might not be the best idea if you're going to have it outside in the sun though, but it should last many years indoors. If they break, it would only cost cents to repair. 
    If you're planning on placing them outdoors, you can try making your own white acrylic sheets and cutting them with a jig saw or dremel. Might be more expensive, but very durable and waaaay cheaper than cropking.

    Nice setup, but I'm thinking you would be better of using LED's even though you have to pay more.

    Less heat to worry about and you'll spend a lot less in the long run with the reduced power consumption.

  • Eric Hendrickson 1 year ago

    Nice setup. How do you keep the CropKing end caps from leaking? Did you glue them to the channel?
