Orchid Care - Orchid Fertilizers - Technical Stuff 

There's a lot of information on a fertilizer package. Fortunately, there are standards manufacturers must follow so understanding what's inside and comparing different products isn't difficult. 

Macro-Nutrients and Micro-Nutrients

Nutritional elements are divided into 2 categories; macro-nutrients and micro-nutrients. Plants need large amounts of some elements (macro-nutrients) and only trace amounts of of others (micro-nutrients).

Macro-nutrients -  All fertilizers contain 3 main elements; Nitrogen (N), Phosphorus (P), and Potash (K). These elements are called macro-nutrients. The 3 numbers on the front of the package describe the percentage of how much of these elements are inside. So if your fertilizer package has 7-9-5 on the front panel, it contains 7% nitrogen, 9% Phosphorus, and 5% Potash.

Micro-nutrients. Micro-nutrients, or trace elements make up the remaining 10 elements needed for a complete nutritional diet. Fertilizers will always contain the 3 main elements (or macro-nutrients), but many skimp on micro-nutrients to cut costs (look on the back of the package.)

Hydroponic Advantage: Hydroponics never relies on the growing material for any nutritional value. Hydroponic fertilizers always contain all 13 elements needed for a complete, balanced nutrition program.

How Can Nutrients with Lower Numbers Work Better?

It all has to do with the purity of the chemicals, not the amount. Many nutrients are made from low grade minerals which are much cheaper (1/4 the price!). Low grade minerals contain filler elements that your plants cannot use - not good for orchids.

In nature, orchids roots are designed to quickly absorb anything that comes their way. The roots act like a sponge but are sensitive to harsh chemicals. Their nutrient supply is pure and doesn't contain cheap chemical fillers.

Why jeapordize your plant's health with cheap fertilizer that's mostly filler? 

Hydroponic Advantage: Fertilizers designed for hydroponics use quality ingredients because hydroponics delivers the nutrients directly to the plant's roots - without the soil getting in the way. 

What About Organic Fertilizers?

Organic means "the nutrient contained in the product is derived solely from the remains of once living organisms". This includes animal wastes, crop residues, compost and numerous other byproducts. 

Organic fertilizers sound good but most are incomplete in their nutritional value. They contain only one or two nutritional elements so blending different products is necessary. The result is uncontrollable, difficult to measure, and usually carries an odor. You never really know what your plants are getting.

Earthworm castings, seaweed, and bat guano head the list of organic remedies. Do you really want to put this stuff on your plants, and in your home? Why take a chance when complete, balanced nutrition is so easy? 

Hydroponic Advantage:  A complete, balanced nutrition program is easy with hydroponics. Our hydroponic nutrients have all the elements needed for healthy growth in an easy to use concentrated liquid. Just add a couple of drops every time you water and your plants will be getting everything they need.
