Can red onions be planted by hydroponic methods? Could, almost all types of plants can actually be grown in hydroponics, be it leafy vegetables, fruit vegetables, tubers and fruit plants. Until now there are still many who think that hydroponics is synonymous with leafy vegetables, but not so. Indeed leafy vegetable crops are the most planted species with hydroponic methods because their maintenance and maintenance is easier and less complicated. Leaf vegetable plant is best suited for beginners who are new to hydroponics. Some hydroponics have succeeded in planting fruit and tuber crops hydroponically.

Stages of Planting the Wick Red Hydroponics Wick System.

a.Hydroponics Red Onion Tools & Materials.

Before starting to plant hydroponic onion, prepare the necessary ingredients and equipment first. For hobby scales, tools and materials may use unused or used goods, such as used bottles or jars. In addition to saving costs, utilizing used goods for dihydroponics is also beneficial in dealing with non-decomposing inorganic waste. Here are the tools and materials needed to plant shallots hydroponically;

• Pot (can use finished pot or used goods).
• Tandon nutrients (can use bottles used, jars used, etc.).
• Scissors, cutter.
• Flannel.
• Media planting (cocopeat or charcoal husk).
• Seeds of onion.
• Hydroponic nutrition / nutrition ab mix.
• PH meter.
• TDS meters.
• Water.

b.Preparation Pot and Tonson Nutrition Hidroponik Red Onion.

Pots and tanks can use used items in your home, such as unused jars or used bottles.Here are the steps to prepare the pot to plant shallots hydroponically;

a). The first step is to prepare pots and tanks of nutrients. The size of the pot is adjusted to the size of the jar.

b). Hole the top of the jar lid, shape and size of the hole adjusted with the available pot.

c). Create an air hole on the side of the jar with a diameter - / + 1 cm. (View schema)

d). The air hole is made slightly lower below the bottom position of the pot. (View schema)

e). Cut out the flannel and put on the pot.

f). Put the planting medium on the pot.

g). Toples / tandons in the paint so that the nutrient solution is not overgrown with moss. Colors of paint can be anything as long as it is not translucent.

Preparation of Hydroponics Red Onion Media.

Planting media to grow hydroponic onion can use charcoal husk or cocopeat. Or campan charcoal husk and cocopeat with a ratio of 1: 1 (1 part charcoal husk and 1 part cocopeat). Then planting media is inserted into the pot. Before planting media is inserted, attach the axis (flannel cloth) first.

Preparation of Seeds Hidroponik Red Onion.

Onion seeds can use the onion in the kitchen. Choose a tuber that is completely dry and old, its characteristics are the color of shiny and solid bulbs. Try to use the existing onion bulb root candidate. Then cut the ends of the onion just a little, about one-fifth of the size of the onion bulbs that will be used as seeds.

How to Plant Hydroponic Red Onion Seedlings.

After all the tools and materials are prepared, ie pots, nutritional stamps, planting media and seedlings now it is time to plant. Plant onion seeds that have been prepared, how to bury half of the bulb to the planting medium. Before the seedlings are planted, planting media first watered using ordinary water (water without nutrients). Place in the shade for 3-4 days or until the onion shoots out. If the shoot has grown approximately 1 cm, the contents of the tank with nutrient solution ab mix. Then introduce with full sunlight.

Need for PPM and pH Nutrition of Hidroponic Red Onion.

Nutrition ab mix consists of 2 parts, namely nutrition A and nutrition B. If the ab mix nut is used still in solid or powder form, dissolve it first into the mother liquor. Nutrients A and B nutrients are dissolved separately using 2 containers.The need for ppm of hydroponic onion nutrition varies at each stage of growth, the older the age of the plant the nutritional needs of ppm is also higher. The following ppm nutrients for hydroponic onion from start to plant to harvest;

a). The ideal pH for shallot crop is 5.5 - 6.5

b). Early planting (counted since seedlings have shoots - / + 1 cm) = 400 ppm.

c). Second week = 800 ppm.

d). Third week = 1000 ppm.

e). Fourth week = 1000 ppm.

f). Week fifth = 1000 ppm.

g) Week sixth and beyond = 1200 ppm.

Maintenance and Treatment of Hidroponic Red Onions.

Maintenance and care is a must-do activity for the hydroponic onion plants we planted to grow maximum and as expected. Caring for and maintaining hydroponic onion plants is not that difficult. Compulsory activity that should not be left in the cultivation of hydroponic onion is to ensure that nutritional needs remain met and keep the pH of the water stable. Periodically check the nutrient solution at the reservoir not to run out or dry out. Use nutrients with ppm that match the age of the plant. Also check the pH of water by using pH meter periodically, keep pH stable.

Thus "How to Plant a Simple Hydroponic Red Onion" with me @jomblang. Hydroponic onion can be harvested at the age of 60 - 65 days after planting or when the leaves are falling and yellowing. If you want to use as a seed, let the onion until old and dry in the sun. Good luck and hopefully this article useful.
