How do I grow orchids hydroponically?
Just like for the ones grown in soil, you will require to be positive that your orchids will have proper nutrients, adequate supply of lighting & the correct temperature & humidity range ought to you pick to do hydroponic gardening. In terms of lighting, a 400 watt HID light is ideal for plenty of orchid species. Orchid plant species that need intense lighting may be placed directly under the lamp while low light plants may be placed farther away from the lamp.
The 400 watt dual purpose light fixture can effectively provide a 6′ x 6′ growing area. To promote lush flowering, the Metal Halide lamp ought to get replaced with a High Pressure Sodium bulb that emits the red & orange color spectrum. One time in bloom, orchids may be removed from the grow room & displayed anywhere. It is also important to note that orchids grown under high intensity lights consume more water than those grown outside. However, it is important to make positive not to over water. Ideally, the roots ought to be very dry before watering.
In terms of nutrient feeding, orchids grown in hydroponic gardening using supplemental lighting will require to be fed more often because of their vigorous growth. very potent hydroponics nutrient that you can use is Advanced Nutrients‘ 100% organic nutrients formula, Iguana Juice Grow & Bloom. By using this formula, you can be positive that the roots of your orchid plants won’t burn & they will grow strong, healthy & lush. You can also use all sorts of growing medium for your hydroponic orchids. For example, expanded clay pellets are uniform in size & porous allowing orchid plants to basically stabilize while providing great capillary action. Available in a variety of sizes, clay pellets are a great surroundings for orchids with thick roots & they do not wear out basically so you can use them for several growing seasons. Another lovely mix of soilless medium that you can use is the combination of perlite & vermiculite. Perlite & vermiculite are heated natural minerals which can be used individually or with a mix of peat & bark. Both perlite & vermiculite have a light & fluffy quality that won’t get waterlogged. These media are well suited for orchids with narrow, airy roots.
Finally, in terms of temperature & humidity range, fresh air & lovely ventilation are essential for orchids under artificial lights. High humidity necessary by orchids is a ideal breeding ground for fungus which is why lovely air movement using a wall or a ceiling mounted fan will help to eliminate fungus & viruses while circulating the air. To keep the humidity at a proper range, grow room walls can be draped with plastic. When white plastic is used, humidity retention & increased light intensity can be achieved inside the grow room, thus, allowing you to have better success in growing orchids using the method of hydroponic gardening.

Why exactly would you want to grow them hydroponically? Most commercially available orchids are epiphytes, and don’t grow in soil. They (again, for the most part in a commercially available sense) have spongy roots that can store water, and are generally potted in a mixture of bark, moss and other materials, sometimes even just volcanic rock. This potting medium acts as a way to keep humidity around their roots, humidity being the most difficult factor to control in a typical home environment. Your best bet is to go to a book store and find a beginner’s book. In my experience, Phalanopsis (moth orchids) and Paphiopedilums (slipper orchids) are the easiest to grow in a home situation. Of course, If you live in a warm, humid climate, you have much more options. I’ve found that orchids are near indestructible- it’s getting them to flower that’s the tricky part. In general, bright indirect light, humidity, warm temperatures, and air movement are the key common factors. Just look them up in
