The method of growing orchids in a closed system is becoming increasingly popular due to its simplicity and effectiveness. Planting an orchid in a closed system is that the flower is planted in a container without holes, and water is poured into the bottom of the pot.

When phalaenopsis is contained in a closed system, the effect of external Wednesday, the method was carefully described by flower grower Yulia Aksenova, and Olga Kovalenko planted even in a tank for aquariums.
The method is suitable for dry climates. The planted plant for this principle remains moist. The roots will be stretch down, which ensures the integrity and growth of the root system, this contributes to the rapid growth of leaves and peduncles.
Orchid cultivation in a closed container only touches the roots, the ground part of the plant develops under ordinary conditions. A flower planted by this method requires less attention.
Pluses of the method:
- the culture blooms for a long time;
- the root begins to grow faster;
- creates a natural living environment.
Cons of growing: decay of the root neck, which will lead to the death of the plant, and a high level of humidity.
Planting the plant produce not only for growing, but also for resuscitation of the flower for a certain period.
The flower should be:
- healthy, with no signs of disease;
- with a strong root system;
- with well-developed leaves.
Planting also helps save a diseased tree that has lost its root system as a result of decay. After placing the leafless culture in a tight pot, it comes to life. The flower grows its roots and begins to bloom.
Select a container
A glass container is suitable as a pot. It is more stable and has a beautiful appearance, in comparison with a plastic container. Glass does not have a porous structure, so the roots of the plant do not grow in.
When choosing a transparent vessel, it is easier:
- to control the water level;
- to observe the growth of the roots;
- see the general condition of the plant.
The shape is chosen even or with the edges expanding upwards so as not to damage the root system during transplantation.
Children and small orchids place in all sorts of containers:
- beer mugs;
- small aquarium.
For large plants, choose a large pot.A plastic container is used only as a temporary vessel for transplantation. Holes can be made in it at any time if the growing method is not suitable.
Main components of the substrate
The substrate for an orchid in a closed growing system consists of certain components that cannot be to mix. They are laid in layers.
The composition of the substrate:
- sphagnum moss;
- expanded clay;
- pine bark;
Pieces of bark are made 1-3 cm so that moist air passes freely between the pieces. This will get rid of mold during cultivation. Cones can be an analogue of bark.
Sphagnum moss has disinfecting and antibacterial properties, so it does not need to be processed like other components. It is recommended to collect it yourself or to buy moss where there are small green branches.
This substrate keeps the root intact and protects from decay.
Phalaenopsis in a closed system is grown according to the following rules:
- The container is treated with boiling water for disinfection or sterilized.
- Expanded clay is placed on the bottom with the first layer, which should place about ¼ of the pot ka, this is about 3 cm.
- Moss-sphagnum is laid in a layer up to 0.5 cm.
- The remaining space is filled with bark and charcoal.
- The substrate is poured with settled warm water and left for half an hour.
- The remaining liquid is drained and a flower is planted. Lay a little moss on the top layer, as a mulch.
The roots should not reach the expanded clay with water. After the actions taken, the flowerpot is placed in a permanent place.
Care for the orchid consists of transplanting (if necessary), watering and proper feeding.
A plant may need a transplant if the root system does not fit in the pot. The plant is transplanted in the phase of intensive growth (so the orchid will tolerate stress more easily). The bush is transplanted with a small amount of land on the roots, but pruning dry or rotten ends.
Feed the flower in a closed system with less intensity. Use standard fertilizers for orchids:
- “Kemira Lux”;
Dosage is reduced by 10 times from the instructions.
Only mineral solutions are used for top dressing. Do not fertilize during flowering, within 10 days after transplanting, in hot weather.
- apply in dissolved form;
- sprayed on green mass and visible root system;
- added to the water intended for irrigation.
Fertilizers must contain, in addition to nitrogen, phosphorus and potassium, also manganese, magnesium and boron. Trace elements increase the immunity of the flower.
Features of watering
An orchid, gaining access to moisture, begins to grow faster. Therefore, the amount of water and the regularity of watering is an important stage of care. Expanded clay should always be wet, this allows the plant to draw moisture from the bottom of the substrate.
To determine when to water the flower, look for the presence of condensation drops on the inside of the container. If they are, then watering is not required.
The color of the root serves as a guideline for adding water. If it is green – the substrate is moist, light gray – the plant requires watering.
Water the flower with a watering can on the inner wall of the container to the level of expanded clay. It is also possible to immerse the pot in a container of water for 20 minutes. The main thing is to adjust the frequency of watering according to the microclimate in the apartment.
Diseases and pests
Wet substrate like midges. The optimal insect repellent is a dry mustard powder, which is sprinkled on top of the substrate.
If thrips and scabs are found on the flower, treat it with one of the solutions (reducing the dosage):
The processing interval is 10 days, the number of sprayings is 3-4.
When only the root rots, it is urgently removed from the substrate, washed with water, the decayed parts are trimmed and dried for 4 days.Then they completely change the substrate in the container and plant the flower back.
Growing a phalaenopsis orchid in a closed system allows it to grow efficiently in any conditions. With proper care and following all the rules, you can get a healthy and beautiful plant.
