One of the simplest and simplest hydroponic systems is the floating raft.
This floating raft system is perfect for those of you who want to harbor at a low cost.
In addition, this floating raft is also very suitable applied to areas that often die electricity, because this system does not require nutrient circulation so that it is tolerant to die electricity for a long time.
In this system, the nutrients will be stored in the tub in the absence of circulation and allowed to pool, then utilize the floating force of the board to support the plant.
The boards used are usually sterofoam.
Sterofoam will be perforated the size of a net pot with a spacing of about 15-20 cm.
These holes will be used as a place of plant growth in the net pot.
Because this system utilizes the buoyant force, so if the volume of nutrients falls then the plant will also adjust the voleme height of nutrients so the plant will come down.
This floating raft system is particularly suitable for light plants such as leaf vegetables, herbs, small ornamental plants and unsuitable for heavy plants such as chili, tomato, melon, etc.
In the floating raft system, plant growth is relatively larger because the roots of plants will touch the nutrients directly for 24 hours so that plant roots are able to absorb nutrients with instans.
But due to the absence of circulation, the oxygen levels in this system are limited.
To do this, apply the aerator into the shelter.
Although the aerator requires electricity, but if the power fails at any time it does not matter because as I explained above that the floating raft system is very tolerant to power failure.
Although nutrients are left inundated, it is necessary to replace nutrients once a week to optimize the plants in absorbing nutrients
Keuntungan :
Biaya lebih murah
Pembuatan mudah dan sederhana
Toleran terhadap mati lampu
kelemahan :
Nutrisi dibiarkan menggenang tidaka ada sirkulasi
Kadar oksigen terbatas
Akar mudah busuk
Tidak cocok pada tempat outdor atau harus menggunakan greenhouse
thanks for you atention and see you
Nice...
