The word hydroponics is derived from the Greek hudor, meaning "water and pones [work ]." It basically means working water.
Hydroponics is growing plants without soil. It is a more efficient way to provide food and water to plants and is very effective with orchids.
The simplest way to grow orchids hydroponically is to buy a very basic hydroponic planter.
This method puts an end to over or under watering, the leading killer of houseplants . Hydroponic planters will deliver water and nutrients in precisely the needed amount . The indicator on the planter tells when they are dry or need food.
The dirt-free planting medium of grow rocks eliminates root rot, mold and mildew . Grow rocks are clay that have been expanded by heat and then glazed to maintain a neutral pH balance. The result: healthy and happy orchids no matter how unsuccessful efforts have been in the past.
