thank You so much, that's ver helpful.

Just came across this video and got some really good ideas from you. Thank you !!!

this is great! I will study your videos, this is what I have in mind. I appreciate you making it easy for us to know what works

Barbod, great video. I'm still waiting for part two! You should post your arduino code, too!

AMAZING! How important is having all the sensors? How often do you have to fill the tub?

I would love to know which sensors your are using. Especially the EC one. I’m looking for some affordable sensors to make a similar setup.

I would like how much nutriments you use in your système

Goes all out on the monitoring, cheaps out on the PVC and water reservoir setup lol. With some refinement, this setup could be an amazing setup. I plan to work on building a modular hydroponic indoor setup for vegetable and greens growing that is efficient, mostly automated (I would love full automation but want to keep costs down per module), and cheap. PVC is probably going to be the way to go. What I am debating on is whether to make the entire system 12V DC based or 110V AC based. There are a lot of 12V DC water pump options that are also cheap. All the control stuff can either be run off 12V DC or be run with an inverter or converter. As for the DC source, used server power supplies can provide massive amounts of clean 12V DC for pretty cheap. I might go with the 12V DC option for many reasons even if it complicates some things.

you're very smart and clever. i have learned a lot in your video. newly subscribe. keep making videos and thanks for sharing your talent sir!

How do you properly tap the 1" pvc into the bottom of the 4"? Please help. Thanks!

this looks amazing but for the water level, why cant you just use a valve to slow down the water just like the intake? that way you raise and lower the level much more easier . what am I missing?

From start to finish and lots of Idea, from temperature, ph, ppm, EC till to the wind blowing, ( dont know what is the used for) but its good idea, then to cleaning process, best ever video, thanks and God bless.

As this is an older video, I'm sure someone has already made the suggestion I'd make..get some hydroton (expanded clay pebbles) Use it in the net pots (on the sides and top of your Rockwood cubes) Its a great benefit in a few ways, it gives an almost "soil like" structure surrounding your cubes, while also creating a healthier root zone with no algea growth and more lateral rooting. (if the cubes are exposed to light all roots. Will grow only downward..covering will expand your rooting area (it makes a difference!) ..Awesome build, helped me work out a few kinks on a new idea..I like your feeder line taps, and think I may replicate how you tied them in..very nice Thank you

Thanx for information

Wow, and here I thought I was going too over board with my garden, I'm no longer going to listen to my parents, I'm going to do what makes me happy.

4 years later still the best dyi design. Good planning makes things easier in the long run.

May i have a vidéo about all nutrients u use thank u for that sir 🇵🇫

This is exactly what I want to set up. Thanks!

You are a clever man, well done 👍

Barbod Varjavandi Thank you so much for such a very helpful video. You mentioned you built another section for strawberries, I would like to ask some questions about how you grow strawberries, how many times you run your NFT system a day and what kind of nutrient solution you are using. I would also want to ask about the sensors that you have built. I'd be pleased to hear from you, my email address is [email protected] Thank you so much.

Hi I would like to have to some help to build the control box

Love the sensors!! good job. do you have additional details about the monitoring system?

What size net cups are u using

hydrogen peroxide 12% food-grade only? will kill algae they use this in Fishponds as well, it does not harm the fish. you will have to work out your own measurements and how about using distilled water?. I love the video and it was straight to the point.

brilliant system excellent

Shit man this is a lot of detail

Very resourceful of you.

Your roots are covered in algae keep a cover on the tank that will help with that

Cover the reservoir so no light can get in so u don't algea

As I design my system framework, I was curious if you feel the water flow control line for each tube plus the water height adjustment tube attachment at the drain exit is redundant. Do you really need both? Seems the water height adjustment tube attachment at each tube's drain exit is a clever idea. Why not have the tubes drain down to the next level tube (filling back and forth) instead of all of the tubes draining directly to the recycling pump/tub.

I’m very impressed with your mechanical design. I am going to build a system and borrow your pressure plugs and flattened pipes. I’m not a fan of having those holes above the drain (to install water level change) so I will sort something out. Thanks for posting this video.

Building a new (similar) system myself and live near Santa Clara. I did not see any video on how you heated/flattened the tubing? (to ensure the seed pods/gates were flat on the tube surface) Great video and provided some valuable ideas/guidance.

Great automation, super stuff! It would be great if you could share a video on this- should be helpful and encouraging :) Keep up the good work!

Sir, this is simply amazing, the logistics, the use of the raspberry pi, the pc stick to control remotely, I have few words to describe the level of fascination towards your system, speechless.

Can you please make a video on the sensors and monitoring system that you put up in place.. this will help a lot of guys struggling with expensive systems also, I think you should also automate the doser system

What an excellent engineering works,but not cost efficient at all. Not everyone can afford it.

That’s too scientific for gardening! Gardening is supposed to be relaxing not building a computer system 🤯😳🤫🤫🤫🤫🤫🤐😷

Well described and detailed video. Thank you for the time. Hope it's working well for you.

Hello. Great set up. Could you explain how you attached the elbow in the bottom of PVC tube for the water return? What hole size and fastening process did you use. Thanks!

Can you tell us more about the monitoring system you created? The Raspberry PII and the Arduino with the ibm unit. Maybe a video on how you made it, etc.

Very cool

I saw this Idea to good man mhpgardener ( the water leveling ). I just want to mention. By the way, you have so much Idea that never seen anywhere. God bless for sharing and thank you.

Perfect set up.

Great video

so much high tech stuff but you then could not put a lid on your reservoir to limit algae growth mmmm cover your reservoir and the holes you are not using and your roots would not be green with the algae. loved the basic set up the tech was over the top and the lack of light restriction was poor.

Cover the led no algie

Hi. Love your system. I created an A frame system, though my water level stays high. Will that damage or impede growth? Will the plants grow regardless of level?

I would like to see a more detailed video on this system step by step instructions and the electronics of the system on how to put it together because I like the way you set this system up and I am planning to build my own system as well too! Thanks 🙏

I like listening to folk that are just smart, great video; and I did hit the the subscribe button

you should consider painting the pipes black and then white to make sure no light gets into the pipes. this will solve your algae problem
