Oyas, terracotta jars to save water in the garden

[Christophe]

An ancient technique but brought back into fashion by a young company to save water and which might be interesting to combine with the lazy vegetable garden in these times of heat wave and lack of water ... what do the specialists think?

Their site is very slow and presents bugs, undoubtedly consecutive to the report of TF1 which had to explode their traffic (and their webmaster who is incompetent to react ...)

An ancient technique but brought back into fashion by a young company to save water and which might be interesting to combine with the lazy vegetable garden in these times of heat wave and lack of water ... what do the specialists think?

What is certain is that it starts by making you lose money !!! How much is this thing worth, compared to what it is (a pot) ???

1) I don't like these "touting" arguments ...

2) Why would something "Sioux" necessarily be "antique" or "exotic" ????

It is necessary to make "believe". And everyone knows that the ancient world was wonderful, that exotic tribes are perfect and naturally green (sure, nuclear power plants and rigged TDI engines are not their forte!) ...

So when I see that, I don't even want to go further!

On the background :

a) A plant has a certain "water requirement", which depends on climatic demand: temperature, humidity, wind speed mainly (and other factors: soil fertility, stage of the plant's cycle) ...

b) from there, two things one:

- or this need is satisfied, and the plant does not stress; she leaves her stomata open; gas exchanges are max, optimal photosynthesis, high yield, growth ...

- or the plant does not find the amount of water; it reduces its losses so as not to dry out and thereby its gas exchanges; its growth decreases ... And if it does not succeed, it withers and can die.

So everything will depend on how easily the plant finds water!

So from his root system and the volume he explores on the one hand ...

And of course the amount of water in the soil on the other hand: the drier the soil, the more it retains water ... Plants have a suction force (the reverse of a pressure) of the order of magnitude of 15 bars.

c) So the porous jars, in there ????

- They do not change the physiological mechanism

- They concentrate the water in 1 point ... So yes, the plant will consume less, because 3/4 of its roots are elsewhere! This does not mean that she does not stress!

- By keeping the surface of the soil dry, they avoid surface losses ... This is the only advantage. It is not zero.

So if we pour the contents of a jar on the surface of the ground, it is clear that part of the water will flow, the 3/4 will wet the first cm around then hurry to s' evaporate. From this point of view, "burying" water saves it. Or more exactly, the proportion of water supplied reaching the roots increases, that's for sure.

d) But the "Potager du Laesseux" is much more Sioux than that and does not need to spend money for such tricks:

- the soil is enriched with organic materials, which are natural sponges
- it is permanently covered, which strongly limits evaporation; the hay is dry on the surface at the moment; the jar does not get better!
- above all, mushrooms are grown there (not hats, filaments in the soil called hyphae, 10 times thinner than hair); and mushrooms are miraculous: with the same amount of biomass, they explore 100 times more volume of soil than the absorbent hairs of plants; they go into cracks that have remained damp; their extraction force is around 90 bars, so they are more efficient than plants in extracting water; they associate with the roots of plants to form mycorrhizae, where plants and fungi exchange what they have (plants, sugars from photosynthesis without which the fungus cannot live; fungi, minerals and water). .
- if necessary (but apart from my greenhouse, I still do not water! The video shot yesterday is being uploaded), I use drip (except for the seedlings): a wet "bulb" is formed underground, similar to these buried jars, except that there are no unnecessary walls; the soil naturally constitutes the reservoir - it suffices to measure the contributions; the dripper being placed at the foot of the plant, the volume explored by roots and mycorrhizae and the volume of this "bulb" of damp earth are superimposed instead of being next to each other ... This is worth a few euros for 10!

So I think this "thing" is completely useless or null in a Lazy Vegetable Garden. But it is on TV, what do you want ... There are still people who, in the Hanouna era, think that if it is on TV, it's true! And then there are those who perpetually need to believe in miraculous solutions, as I said, "ancient" or "Aztec". The Rousseauist myth of the "good savage" (or the "good primitive", the one who pulled his wife by the hair ...) ...

But this is only my opinion.

Hello,

Yes, a bit like Did67 actually.
The guy from the report also says that without mulching, it is useless. In short, a kind of antique drip but in terms of localized, precise and controlled watering we are able to do better.
Go!! For fun and experience, we can always have fun putting one somewhere to see. But beyond that I don't see ...
Given the price of the thing, if you want to put a lot, as much to invest in a drip system with timer, this can be precise and it saves water.

12 euros for 250ml!
A pure product of business school, even if the price is justified by an artisanal and local manufacture, the ratio per m3 of water saved is really bad, the pollution ratio too.

That said, I once bought a lot in liquidation of ceramic tips for plastic bottles, which I used a little at the beginning to secure subcultures, and it was good, since my various mulches are effective, including pebbles, and I haven't used it for the past 2 years. On the 20aine bought, a dozen are served. I put a bottle of it the last time to secure a transplanting of California poppy in a half barrel in full sun. I'll see tomorrow if it's been enough.

So I think that a few pots to secure fragile plants in rotation at certain times, are more aesthetic than bottles .... taken by a garden gnome, it's not so bad! Come on, I'm going to drop the porous foot dwarf model! My fortune is made.

After that, these modes pushed by disconnected journalists are quite damaging ...

Olivier.

Didn't you think of the dwarf with a dripping nose?

[Did67]

In the genre, to please Christophe, you could have thought of the Manneken Pis with hanging giant cock, in reduced model with integrated urine mixer!

I'm the one who's going to make a fortune with this idea that I still forgot to patent!

[Adrien (ex-nico239)]

We were interested in it for a while but hey, in the end we gave up ... nothing but the holes to dig

And then in case of prolonged absence a drip network with programmer is so simple.

Although with a good mulch everything is comfortable 15 days ... so

Hello, this system reminds me of the ceramic figurines I had in the flower pots https://www.youtube.com/watch?v=fDYFoSMl-5M

but here it’s with a simple bottle
here are the figurines

this principle of porous mud may have an advantage over drip: takes into account the humidity of the soil

with a drip you distribute a constant flow of water, whether the soil needs it or not

with the porous vase, if the soil is wet it does not empty and conserves water: the vase is empty only if the soil is too dry

it can therefore be a solution by using cheap porous vessels, not by buying them at a higher price than an automatic watering management system with soil moisture measurement

why not just earthen flower pots, plugging the hole with silicone sealant
