are required in large or small quantities by plants.
Therefore it is necessary to give them a suitable nutrient solution for hydroponic vegetable
. There are several formulas to prepare nutrient, but at school level
it is best to buy ready-made solutions which are sold commercially to provide balanced nutrients . The simplest formula is to prepare it is: calcium nitrate ................ 118 gr. Magnesium sulfate .......... 49 gr.monopotassium Phosphate ....... 29 gr.
Water ..............................
Black Roots: pH 2 to 3 (plant death)
If this happens we recommend changing the water irrigation
Form:
The concentration of nutrients to use will depend on the status of the plant and for seedlings
used half the concentration of a mature plant.

If it appears that the substrate becomes too dry during the day by winds, by heat or because it is
ret Substrateiously the garden to detect the presence
adult insects, eggs, worms and aphids when they are in their early days of
development. This review should be done in the early morning or late in the afternoon
, because after sunrise the temperature rises and the bugs are not easily
locate, since they have been hidden for protection.
The review daily or every two days and covers the entire garden
considerably reduce the number of insects as the constant and gradually to phase out their states allow CHTMdot;
There are also insects that cause no harm, but that feed on pest insects,
these are the pebbles, dragonflies, wasps and lizards, so we must protect them.

get the morning sun on trays where they should not miss the water until the day following crops are green. To our chain this method will work well, avoid the consumption of seeds by birds, is easy to use. It is important to have a production of at least one tray daily if you are experimental use as food for rabbits.In experiments that can havecer in this unit are: effects of light on germination of seeds, the effect of nutrients on germination of seeds,
effect of temperature, etc.
