Understanding media through moisture retention curves

In this video I do a short introduction to the concept of moisture retention curves. I discuss the two properties that make up the curves as well as how to interpret them. Here are links and references for the papers or books I consulted to get the graphs used in this video:

One of the best channels anywhere.

[@ScienceinHydroponics]

I have excellent viewers as well!

[@hanumkas]

Loving your research paper series, Daniel! Keep it up. Informative content as always.

[@ScienceinHydroponics]

Thanks for your comment! More videos like this coming.

[@hanumkas]

​@@ScienceinHydroponics Please add formulation of stock solutions of popular recipes that has been researched on in your videos as well. I think it'll be a great addition like recipes of Yamazaki Strawberry etc.

Great video, thank you! I'm really glad you brought up the physical size of the pieces of media too at the end.

[@ScienceinHydroponics]

Thanks for commenting. Certainly, the media size is very important, the packing of the media can also make an important difference. This video only scratches the surface of the topic!

[@euphioquestion420]

yes!!! so important, glad to see you educating on this subject

[@ScienceinHydroponics]

I had been thinking about this video for a while. Make sure to comment if you have any suggestions for other topics you would want me to cover.

Glad to see you back ..Not that I do hydrponics ..but I mix my media normal soil with rice husk ..10x25KG cost me 10 euros for the rice husk.
I would like to see a video of hydroponic solution and PGR mix if you can .
Solution B with a PGR

[@ScienceinHydroponics]

Thank you, great suggestion! I will definitely take that into account.

[@chrisscotney4124]

If you need any PGR sent to you I could send you some of mine .. read out via your blog or any other means I do t do twitter

[@danield9990]

Really great video, super informative. I truly learned a lot.

[@ScienceinHydroponics]

Thanks. I'm glad you liked it! Please feel free to leave any suggestions you might have for future videos.

[@pelegsap]

Incredible, thanks for this video!

[@ScienceinHydroponics]

Glad you liked it!

[@nathan-wh6nd]

very informative thank you for making !

[@ScienceinHydroponics]

Glad it was helpful! Thanks for watching!

[@Mean_Mr_Grinch]

Wow. Very informative.

[@ScienceinHydroponics]

Thanks for watching!

[@viadirecta7922]

Thank you for sharing! Where can i find comparative curves for pebble clays (Hydroton, Arlite...)?

[@ScienceinHydroponics]

If you search for the media + moisture retention curve you can often find papers with the moisture retention curves. The manufacturers will also often have them if you request them directly.

[@yohansilva9679]

Hi sir,
How we can find P1 and P2 of this curve?

[@ScienceinHydroponics]

Thanks for commenting. These curves show you how media behaves in terms of tension as it dries, they do not talk about irrigation practice, which would be a different topic.
