Ebb and Flow Hydroponics

The ebb and flow hydroponic system works by periodically flooding a grow container with the nutrient solution and then letting container drain back to the reservoir. The system is sometime referred to as a flood and drain system. The flooding can be done manually but it is most often controlled by a timer and uses a pump to move the nutrient to the container and gravity to move it back. Like most media based hydroponic methods ebb and flow hydroponic systems can survive power failures because the media holds nutrient between waterings. The ebb and flow systems also have other advantages.

Drip Hydroponic Systems

The drip hydroponic system is one of the most common in the world. Drip systems are used to grow everything from lettuce to cut flowers and melons. The design of the drip system is simple.

Hydroponic Growing: Plants without soil

Hydroponics is the method of growing plants without soil. Hydroponics it literally means working water. It’s not a modern idea and it really isn’t hard if the plant’s primary requirements are met.

Hydroponic Fertilizer- Magnesium and Sulfur and the Micronutrients

In my last article I discussed the Primary macronutrients in Hydroponic Fertilizer
and calcium which is considered a secondary macronutrient but which I think should be considered a primary. If you are interested in learning about the rest of the elements that make hydroponic fertilizer so effective, I’m going to lay out the basics here. After reading this article you’ll know what the other elements in hydroponic nutrients do.

Hydroponic Fertilizer – The Macro Nutrients

In my reading I’ve read that there are between 13 and 17 essential plant nutrients. I think the people who say there are 17 are padding the list a bit since they include carbon, oxygen and hydrogen and sometimes water but that is all academic. When you get down to the nitty gritty most people who think think of hydroponic fertilizer when they think of the chemicals you add to the water. And when your thinking of plant food there are 3 groups of nutrients on your mind: the Primary Macronutrients, the Secondary macronutrients and the micronutrients. In this article I’m going to deal with the Macronutrients and the red head step child of plant nutrition calcium.

The Basics of Indoor Home Hydroponics

Growing indoor plants at home successfully using hydroponics comes down to controlling environmental factors. If you want to grow plants hydroponically you need to control the light, the nutrient solution and air supply.
One of the most important factors you need to control while growing indoors is the light. You need to supply enough light for the best growth but at the same time you need to make sure you don’t provide so much light you burn your plants or overheat your growing space. You can choose to use artificial light from metal halide, high pressure sodium, fluorescent or leds to provide the all the light your plants need. Or you can use sunlight and use an artificial light just to supplement the light supply so you can grow plants that require more light.
Another important factor to control is the nutrient solution. When growing hydroponically the nutrient solution provides your plants with all the food they need to grow as well as the water they need to survive.since there is no soil to provide nutrients your fertilizer must be complete, with all the macro and micro nutrients a plant needs. It must also be mixed to the correct strength. If it is too strong the nutrient solution can burn the plants roots and kill the plant because they won’t be able to absorb water. If it is too weak it can slow plant growth and cause the plant to develop nutrient deficiencies.
The final important environmental factor that needs to be controlled is air supply. Plants need both carbon dioxide and oxygen. The carbon dioxide is used in the process of photosynthesis which the plant uses to make sugar for food. The oxygen is needed both around the root and around the foliage. Plants produce oxygen but remember they also use it just like you. If you want to grow healthy hydroponic plants make sure that there is a healthy amount of oxygen near the roots and enough air movement around the leaves so that the plant can get both enough oxygen and enough carbon dioxide.
Growing indoor hydroponic plants can seem very complicated. But if you can control the most important environmental factors you will find it as easy or easier than growing using soil.
