The Key Points for Cultivating Hydroponic Clivia Miniata
Let me tell you about the planting contents of the hydroponic flower Clivia Miniata, the key points for its care, as follows:
Clivia Miniata is native to southern Africa, growing under trees, so it is afraid of heat and not cold-resistant, prefers a semi-shaded and humid environment, and is afraid of strong direct sunlight. The optimal growth temperature is between 18-22℃, below 5℃ and above 30℃, growth is inhibited. Clivia Miniata likes a ventilated environment and is suitable for indoor cultivation in hydroponics.
Clivia Miniata can also be hydroponically cultivated, and the method is as follows:
Container Selection
For hydroponic cultivation of Clivia Miniata, the container must be chosen first. Generally speaking, a transparent glass container is preferable. If raising a seedling, just a glass jar would suffice. For large-scale hydroponics, a metal mesh with a mesh size of one centimeter can be made with fine iron wire, and then a glass hydroponic box slightly smaller than the metal mesh can be made; a goldfish tank can also be used as a substitute. Then, place the metal mesh on top of the hydroponic box, and insert the Clivia Miniata seedlings into the nutrient solution through the mesh, with the depth of the roots in the nutrient solution not exceeding the false bulb of the roots.
Nutrient Solution Preparation
The nutrient solution is divided into inorganic and organic types. The inorganic nutrient solution can be prepared according to the following proportions: calcium 1.5 grams, ferrous sulfate 0.01 grams, urea 1 gram, potassium dihydrogen phosphate 1 gram, magnesium sulfate 0.5 grams; after mixing these five inorganic salts, dissolve them in 1000 grams of water for use. The organic nutrient solution is prepared as follows: roasted sesame flour 100 grams, bone meal (made from salt-free fresh bone) 100 grams, soybean cake powder 150 grams, ripe sesame powder 50 grams, then dissolve in 1000 grams of water. Comparing the two nutrient solutions, the organic fertilizer is rich in components but not high in nutrient content, while the inorganic fertilizer is relatively simple but has a significant effect and takes effect quickly. To make up for each other's shortcomings, they can be used in combination. If used alone, inorganic fertilizer is applied once a week, and organic fertilizer is applied once every 5 days.
Water Usage
Hydroponic Clivia Miniata cannot be watered directly with tap water; it must use "stagnant" water. So-called "stagnant" water refers to tap water placed in a container and exposed to sunlight for 3-5 days, allowing harmful bleaching powder and other chlorinated substances to precipitate from the roots of Clivia Miniata. The "stagnant" water, from the appearance, has precipitates changing from strip-like to clumpy, and the ideal water color is green. After "stagnating" the water, make sure the water level does not cover the false bulb. If the water level is too low, Clivia Miniata will not get enough water; if it is too deep (covering the false bulb), it will cause root rot. During the breeding process, it is necessary to observe the changes in water quality. If the roots start to turn yellow or black, it indicates that there is a lack of oxygen and nutrients in the water, and the water must be changed immediately.
Air, Sunlight, Temperature
Whether the aeration of the roots of hydroponic Clivia Miniata is handled well is the key to success or failure in hydroponics. After a period of cultivation, a layer of green algae grows on the roots, and too thick of an algae layer can severely affect the root's respiration and corrode the nutrient solution. At this point, use a soft and clean brush to gently remove the algae layer from the roots (there is no need to clean it very well, as a small amount of algae on the roots does not matter). In addition, it is necessary to check whether there is enough oxygen in the water. The method of checking is: place two or three small fish in the hydroponic box, if the fish swim freely in the water, it means there is no oxygen deficiency; if the fish always float to the surface with their mouths and gills exposed to breathe, it indicates oxygen deficiency.
After discovering oxygen deficiency in the water, it is necessary to supplement oxygen. There are two methods: one is to change the water, and the other is to supply oxygen to the water with a small oxygen pump. In terms of sunlight, Clivia Miniata is a semi-shaded plant, and attention should be paid to lighting, especially in the summer, to avoid strong direct sunlight and allow it to receive scattered light. In addition, according to the phototropic nature of Clivia Miniata leaves, it is necessary to ensure that the leaves receive uniform light; otherwise, the leaf lengths will be inconsistent, and the growth direction will be disordered. Generally, the lighting angle should be adjusted every two or three days. In terms of temperature, the ambient temperature for adult Clivia Miniata is best between 11℃-25℃, and for seedlings, it can be slightly higher, at 20℃-35℃. For growing Clivia Miniata in water, it is necessary to master the day-night temperature difference. In winter, keep the daytime temperature around 20℃ and no lower than 15℃ at night.
The above experience on the key points for caring for hydroponic Clivia Miniata may provide you with some help in your life!
