Thank you so much for the detailed presentation.You talked about hdpe material for the rails but pvc pipes for the plumbing which is non-food grade,isn’t that a little problematic?
Great video, thanks. I heard that around 2 liter/minute of waterflow would be optimal in a NFT system. Do you keep a certain speed of the waterflow in your channels?
Concerning irrigation, you mean the pump will work continuously 24 hrs watering plants, some references say that there are cycles of watering, for example, 3 to 4 times daily?
The NFT system runs 24/7 and recirculates. As the plants transpire, water is added to the reservoir via float valve and the nutrient controller takes care of nutrient and pH set points. Propagation systems irrigate on a timer. Growing medium needs to drain between irrigation's so oxygen can fully saturate the root area.
@@DM-sc4zy We do. This all depends on how balanced you nutrient formula is for the plant type you are growing and how pure your source water is. We dump our tank every 8 weeks.
This system uses 2" PVC pipe from pump to NFT tables and 4" PVC pipe from tables back to reservoir. Return plumbing pitch is ¼" per foot and the system runs 24/7. Tank is below ground and head loss calculations are minimal so we can get away with using a 3/4 HP pump for the whole operation.
Sorry for replying late. This one slipped through the cracks. We have had root aphids before but not in this system. One benefit of quick crop turns and pests don't have a lot of time to develop and get a foot hold.
We are not in a hot area so do not require chilling the water. It warmer climates, we over size the reservoir so thermal mass plays a part. You can use a chiller to cool your water or build a heat sink to help pull the heat from the water. You also need to make sure the water is fully saturated with O2.
Chiller or heatsink too cool the water, drop in heater or boiler to heat the water. If water is too warm you can use ozone to super oxygenate the water but it is a fine balance.
Here is the link to Finishing Channel: shop.amhydro.com/collections/nft-system-components/products/amhydro-groclean-finishing-channel. Recommend having amhydro do a freight quote for you before ordering online. If you add channel to your card, a prompt will pop up that refers to this process.
Thanks for sharing the information. Kindly let me know the weight of each lettuce so we can calculate the revenue. if you don't mind can you let us know the monthly electricity and water consumption?
We sell by the plant verses weight but you can use 6 to 8 ounce for your calculations. For this greenhouse we user roughly 60 gallons of water per day and roughly 129 KWH per day; that is avg over a year. However, this is not a perfect model for commercial production since our mild climate allows us to not use a chiller to cool water or a walk in cooler for produce. Both of those items are power hogs. We also have hydronic heating in the floors basically putting extra money into the infrastructure verses paying more for heating. As you pull your business plan together, feel free to reach out to us at info@amhydro.com.
Channels are Irregular Polygons. The top is 2" wide so the hole has to be less than 2" in diameter. Anything hole larger than 2" would degrade the strength of the channel. Holes for finishing channels are 1.75" and holes for nursery channels are 1.6825".
I’d like to design one of these for the top of a parking garage in the middle of a small town as a farm to table offering as a food & beverage use in the form of a small sustainable skybar restaurant. The idea is to create a total green environmental offering in the middle of the city.

How many holes in starter kit you can grow.
Amazing, I finally found my channels.
Thank you so much for the detailed presentation.You talked about hdpe material for the rails but pvc pipes for the plumbing which is non-food grade,isn’t that a little problematic?
It's all about what the roots touch. The plants stay in the HDPE channel until harvest.
Great video, thanks. I heard that around 2 liter/minute of waterflow would be optimal in a NFT system. Do you keep a certain speed of the waterflow in your channels?
We design around 1 Liter per minute per channel but our target flow rate is half that.
Do you have any dealer of your products in Canada? Thanks

@@AmericanHydroponics Wondering if you have to change out the nutrient tank and how often.
@@DM-sc4zy We do. This all depends on how balanced you nutrient formula is for the plant type you are growing and how pure your source water is. We dump our tank every 8 weeks.
Does AmHydro provide a plant / crop management system in order to track crop rotations as well as output / costs etc. ??
Very inspired by your leadership and knowledge. How did your stacked experiment turn out?
Hello Ma'am, Thanks for sharing your valuable knowledge. Please share nutrient delivery plumbing system if possible.
This system uses 2" PVC pipe from pump to NFT tables and 4" PVC pipe from tables back to reservoir. Return plumbing pitch is ¼" per foot and the system runs 24/7. Tank is below ground and head loss calculations are minimal so we can get away with using a 3/4 HP pump for the whole operation.
for seting half acre of hydroponic structure what will it costs
High quality video. Well done.
Thank you. We get a little better with every video we make.
Very informative thank you.
Have you had problems with root Aphids? Great video BTW. Thanks
Sorry for replying late. This one slipped through the cracks. We have had root aphids before but not in this system. One benefit of quick crop turns and pests don't have a lot of time to develop and get a foot hold.
How do you manage the water temperature in the summer? do you run water chillers.
We are not in a hot area so do not require chilling the water. It warmer climates, we over size the reservoir so thermal mass plays a part. You can use a chiller to cool your water or build a heat sink to help pull the heat from the water. You also need to make sure the water is fully saturated with O2.
How to maintain the temperature of the water of nft ,my seedlings is affected due too the temperature of the water ...thank you hope you answer me.
Chiller or heatsink too cool the water, drop in heater or boiler to heat the water. If water is too warm you can use ozone to super oxygenate the water but it is a fine balance.
Hi, is the nutrient solution in your nursery channel the same as the finishing channel (ec and ph)?
Yes. The Nursery and Finishing run off of the same reservoir but the propagation system is on a separate tank.
This is great, but can you post another video of aquaponic!
Thanks but we do not offer or grow Aquaponically. Recommend looking up Nelson and Pade Aquaponics.
Do you have a web address where I can order the channels?

@@AmericanHydroponics Thanks for the information. Actually in your farm model, will growing strawberries be possible & profitable.
Do you have a supplier in Canada?
Why there are 2 inch holes not 3 inches? What's the difference ?
Channels are Irregular Polygons. The top is 2" wide so the hole has to be less than 2" in diameter. Anything hole larger than 2" would degrade the strength of the channel. Holes for finishing channels are 1.75" and holes for nursery channels are 1.6825".
Hi. What size reservoir tank is recommend?
The reservoir for this system is 1200 gallons
I’d like to design one of these for the top of a parking garage in the middle of a small town as a farm to table offering as a food & beverage use in the form of a small sustainable skybar restaurant. The idea is to create a total green environmental offering in the middle of the city.
Do you carry organic certified nutrients
We do not.
