How to grow orchids hydroponically? Detailed guide to care methods and growing environment

1. Placing correctlyOrchidsolution

The interval between adding orchid solution is generally 15 to 20 days, and 30 to 40 days during the dormant period. To ensure the amount of solution added is accurate, a syringe can be used to measure it. Orchid growth can be divided into three stages. The first stage: the orchid is pulled from the soil, washed clean, and transplanted into water culture until white new roots grow; this stage is called the "adaptation period," and during the adaptation period, add only 0.4CC to 0.5CC of orchid solution per pot each time. The second stage: when the new roots come into contact with the planting water, this is called the "normal growth period," and the amount of solution added each time is 1CC to 3CC. The third stage, the dormant period, the amount of solution added each time is 0.4CC to 0.5CC.

2. Replacing the transplant water

During the growth process of the orchid, root metabolic matter sheds into thegrowingwater, and over time thegrowingwater becomes dirty. To keep the water clean, rinse the whole plant and replace the growing water at any time; after changing the water, the solution must be added again.

3. Preventing the growing water from breeding [mosquitoes] in summer

Any one of the following methods can achieve the goal: 1. Cover the inner sieve fully with the stones or sponge used to fix the plant, to prevent mosquitoes and insects from entering. 2. Use the method of replacing the growing water, changing it once every fifteen days. 3. Use a mosquito-killing spray to spray a small amount of mist into the growing water in the pot, taking care not to burn the plant.

Orchidflower'shydroponic method is only a reform of the planting method; it does not change theorchidflower's ecological habits. Orchids like shade, coolness, and ventilation. The growing temperature is between 18 and 28 degrees; in summer and early autumn, more shading is needed, with light intensity of about 50%. In late autumn, stronger light should be given to promote full growth and more flowering. When displayed in a room or hall, keep the air circulating and the light must be bright. Avoid placing them where there is cooking fumes or polluting gases. In summer, in an indoor environment with air conditioning, orchids will grow more vigorously.
