Water Level Indicators for Hydroponic and Sub Irrigated Tanks of Growing Medium

A quick glance at the water level indicators allows growers to determine the liquid levels in hydroponic and sub-irrigated tanks of growing medium. This provides 'peace of mind' for the grower and greatly reduces the chance of crop failure due to the lack of water.

I'm so glad to find that you are still making videos. I'm a big fan of your work and have been using some of your methods at home with amazing results for about two years now. I've incorporateed Your method "The Kratky" method, I also call my containers "my Kratky containers" in many of my videos and will continue to do so because it just works. Thank you Dr. Kratky for your time and efforts to share with the world your fantastic method 👍

Dear Dr. Kratky, your work turns on big light bulbs in those of us that love to grow plants. You're a great teacher. Thank you!!

[@growkratky5558]

Thank you. I encourage you to make adaptations and improvements to these methods!

[@JebGardener]

I made a similar level indicator with a wine cork and bamboo skewer. I knew it would absorb water and rot but it worked OK for one grow. Your way looks much better. Thanks!

[@oneofnumbers]

Love your channel Jeb (con mucho respecto), and thank you for telling us about Dr Kratky!

[@MattGarver]

I like your use of the construction mixing tubs in the greenhouse to grow the different vegetables.

[@KhangStarr]

Great and effective idea that does not cost too much. Thanks for sharing!

[@doogiehowser78]

simple genius of an idea

[@destitute8493]

An electronic dipstick should be easy to construct. Lamp lights when water closes a circuit. I wonder why no one has done it?

[@maximoptim1701]

why not just add the water by using a measuring jug and then mark where the polystyrene lifts up to. Would this work?

[@BenjasUberHobby]

Lots of great info thanks!!!

[@sbfarmer8]

sorry dr. I prefer to drill holes on the outside container to gauge the water level. once the hole is drilled to the appropriate level, no matter what rain may come, it can be over watered... the hole just drains the water out. I use 2, 1/4 inch holes.

[@williamryan3503]

Thanks for your informative simple solutions They are spot on. I was concerned with this water level unit letting mosquitoes into the water below the screen. Gluing a jelly jar lid with a hole in it for your pvc pipe and screwing on the glass jar solved the bug and rain water intrusion for out door growing. Acrylic latex caulk works well as a glue if you can leave it set overnight.

[@growkratky5558]

Thanks for sharing.

[@Rhonda2580]

Do you secure the PVC pipe to the container in some way? Or is it just held in place by pressure from the top of the container?

[@mbainrot]

Here I am thinking about some super comlex sensor based contraption bahahaha, thank you so much mate

[@richarddadzie8366]

Just block the two ends of a straw and use it. It should work well and save all the time and hustling

[@growkratky5558]

Great idea!!

[@Kang_Kabayan]

Terimakasih bagus sekali

[@nguyentantai9036]

Good

[@aeneas1677]

just wondering, how would you know which is max and which is min? also, does the amount of foam sticking out of the pipe represent how many centimetres from the bottom of water there is?

[@growkratky5558]

Yes, the length of the indicator rising above the pipe slightly underestimates the height of the solution in the tank. I don't understand the first part of the question.

[@gatetres]

can you show how to build the ginger , tumeric plants?

[@growkratky5558]

Several years ago, the University of Hawaii produced a youtube video on ginger - kzbin.info/www/bejne/rmG4fHWBhd1rnck

[@quietspacearts]

will neoprene be food safe for water hydroponics?

[@growkratky5558]

Although I don't have information on my neoprene, there are food safe sponge neoprenes available. I am hoping that this youtube encourages someone to find an even better material than the sponge neoprene which I used.

[@nightwaves3203]

Kratky method in 5 gallon buckets how low of fluids is too low and after the roots are adult stage what would be the max fluid level?

[@growkratky5558]

Below 2 inches from the bottom is likely too low and above 2 inches from the the bottom of the net pot to the solution surface (after the initial drop) is likely too high.

[@nightwaves3203]

Thank you for adding some confidence to my fooling around :)
