Simplified hydroponics, the video
We had already spoken here of Jordan Mariani and his hydroponic experiment "poor", inspired by the simplified hydroponics programs promoted by FAO in developing countries.
Here's the video, which shows the stages of implementation and the results obtained.

I would like to have some indication as to the fertilization of some tomato plants. What are the requirements for nutrients? As should be assayed? their frequency?
Thank you very much

Hello, if the medium is the earth are specific fertilizers rich in nitrogen, often granular, designed specifically for tomatoes. Since the composition of nutrients is especially for everyone, you have to stick to the dose on the label.
Obviously if you have to grow in open land increased a little 'dose compared to the vessel.
If it's a few plants in pots or hydroponic you recommend this product:

Hello, congratulations for the experiment!
I would like to ask advice about simplified hydroponics because I'm doing an experiment in my garden.
I'm cultivating bean plants with roots immersed in a bath with solvents to hydroponics, but without aerator. How I used a gel inert substrate. The plants grow very slowly, however.
I would like to understand how to make crops grow faster, where can I recover substrates that have nutrients?
And 'the best aerator for the plants?
I hope for your help,
James

Hello,
I do not know the inert gel you speak, you could give me a link? Make sure it is specifically designed for growing, or will inhibit perspiration and alter the culture environment.
If growth is slow may be the fault of fertilizers (poor quality or inadequate doses administered) or water quality, but it certainly would help an oxygenator.
Keep in mind that outdoor, without the help dellle artificial lamps, growth is still slower.
The substrate with nutrients need is only the water (or better, the nutrient solution), any other material you need only to provide anchorage to the plants. This is the beauty of hydroponics.
Let me know!

The substrate I have found in one of the best stocked shops in my area, the Viridea in Vicenza.
It is a polymer, the sachets contain the granules which swell in contact with the water and can be of various colors red, blue, yellow, green! I do not remember the brand but is specifically for hydroponics and is completely inert.
The objective of this experiment is to understand what seeds are ideal for growing directly from the substrate ... you have suggestions?
I think I will not use the aerator or lamps, simplicity is one thing I like hydroponics! Instead, I totally obscured the bathtub and I put a aluminum foil to reflect the natural light ... also use a mini-greenhouse for extra warmth.
See you soon!

hello,
is something
http://www.criado.it/doc% 20gel.html
?
Because in this case is used instead of water, not in addition.
The gel absorbs water and nutrients and releases them in time. But if your plants have roots immersed in water and most are supported from the gel the result will be a layer saturated with water and nutrients to the base of the stem and water is not fertilized in contact with the roots.
Such a situation does not allow the plant to eat properly.
I would think to a substrate more manageable, such as expanded clay.
You can germinate in rockwool cubes or peat, and then insert them directly into the substrate. Theoretically you can germinate directly in the clay (or other medium) but the results are poor. I do not think however that you can germinate in the gel. There are more suitable than other plants all'idroponica.
The water tank must be oxygenated: If you want to use an oxygenator sure it filled in the fall and has a frequent replacement. The roots are rotting in stagnant water.
And 'right to use the mini greenhouse but only until the plants are small or the climate is too harsh: if it is subsequently possible to better the outdoors.
And attention also to aluminum: it tends to concentrate the light in 'hot spots' and the risk of burns. Better to opt for a white plastic sheet.
That said, good luck and if you send us some photos.

Hello, yes those are exactly the granules.
The germinating seedlings in peat pots and then are moved to the gel containing the claims. The gel is mixed with water.
Let me explain:
0 gwerminazione in peat
1 net pot plants placed in pots
2 substrate gel that is inserted into the pots
3 cups stuck in a pegboard
4 when the roots are sviluppono enough to draw water
5, the nutrient solution is dissolved in water only
if you leave me an email I send you pictures of the event ...
Meanwhile, thanks for genitli directions!
soon

Yes, I understand that this is the end of a traditional deep water with gel instead of clay and without oxygenator.

For easier management can germinate in rockwool cubes, but not in gel beads.
