Onion seedlings without soil allow you to grow onions at home at minimal cost. Onions grown without the use of land are in no way inferior to crops growing in summer cottages.
Conditions for growing onions
Onions are a cold-resistant crop and grow at temperatures from +18°C to +20°C. When growing on the windowsill you need to ensure that the crop does not experience increased exposure to sunlight or heating radiators.
Humidity is not a prerequisite for growing onions for greens. To obtain more juicy greens, it is recommended to occasionally spray onion feathers. In this case, moisture should not get on the bulb.
Immediately after planting, the onions are removed for 3 days in a dark place. During this time, roots are formed. Subsequently, the culture requires access to light. In winter, lighting should be used using LED lamps or special lighting devices for plants.
Preparing the bulbs
To grow onions without soil at home, choose early-ripening varieties that quickly form green mass. The diameter of the bulbs should be about 3 cm.
The following varieties of this crop are grown on the windowsill:
- Strigunovsky;
- Trinity;
- Spassky;
- Union.
To solve the question of how to grow onions on a windowsill, you first need to carefully prepare the bulbs. This procedure is carried out in several stages:
- First, remove the top layer of husk.
- Then about 1 cm of the neck is trimmed to stimulate feather growth.
- The bulbs are placed in warm water for 2 hours.
- Planting material can be planted using the chosen method.
Ways to grow onions without soil
There are several ways how grow green onions at home. If the crop is grown in a bag, then substrate preparation is required. An easier method is to plant the bulbs in egg racks. To obtain a large harvest, it is recommended to use the hydroponics method.
Growing in a bag
To get onion feathers at home, use a substrate. Its functions will be performed by pine sawdust, sphagnum or toilet paper. The procedure for planting onions in a bag is identical regardless of the material chosen.
Compressed sawdust is best suited for growing this crop in a bag. First, they are placed in any container and filled with boiling water. When the mass has cooled, you can begin planting.
If you use toilet paper, fold it in several layers and pour boiling water over it. The resulting mass is used to plant bulbs on a windowsill without soil.
The prepared substrate is placed in a plastic bag. When growing onions in a bag, it must be placed tightly in the substrate, the layer of which should be more than 2 cm.
After landing, the bag is inflated and tied.Be sure to exhale into the bag several times, since feathers actively grow in the presence of carbon dioxide.
It is kept in this state until the feather grows to its edge. The first harvest when growing onions in a bag without soil is obtained 3 weeks after planting.
Growing in egg cartons
Another super way to grow onions is to use egg cartons. Both plastic and cardboard grilles are suitable for this. If you use plastic grilles, you need to make a small hole in each cell.
The landing procedure includes the following steps:
- Warm water is poured onto a baking sheet or plastic boxes, and then egg racks are placed on it.
- In each cell you need to plant one onion that has undergone the necessary processing.
- Periodically you need to add fresh water to the pan.
Growing hydroponically
To grow green onions, you will need several jars of sour cream or yogurt. In each of them, a hole is made in the lid for the onion.
Then take any fertilizer for vegetables containing phosphorus, potassium and nitrogen. It is diluted with water according to the instructions. To prevent the bulbs from rotting, add a drop of hydrogen peroxide.
Change the water in the jar periodically (every 2-3 days). Planting material must remain dry to prevent rotting.
To get a large harvest of green onions without soil, you can create a hydroponic setup.
First, take a container with a height of more than 20 cm and foam with a thickness of more than 5 cm.Cone-shaped holes are made in the foam where planting material is placed.
A water sprayer is placed at the bottom of the container and connected to a compressor. Intensive feather growth is ensured by enriching the water with oxygen. With this super method of growing onions, the feather grows 30 cm in two weeks.
Conclusion
You can grow onion feathers at home without using soil. Such methods give a good harvest and are low-cost.
The bulbs can be planted in a substrate that is placed in a plastic bag. You can use egg racks or plastic containers for planting. No special conditions are required for growing greens; it is enough to maintain the required temperature and provide access to moisture.
