Hydroponics gardening guide -introduction to growing mediums and hydroponic supplies used in hydroponics
Growing medium is any medium, in which a plant can grow. Generally, hundreds of multiple types of growing medium exist: some are manmade and some are organic. Sometimes, even old AIR can work as a good growing medium for roots.
Defining the best growing medium is pretty challenging and disputable. It is a matter of personal likes, preferences and exact growing needs or requirements in most cases. It is like choosing a car: everyone picks the one, which suits his/her personal likes and requirements: someone chooses a small economic car for city traffic, and someone prefers powerful SUV to conquer sand and morass. Just like choosing a car depends on many factors, while choosing a growing medium it is also necessary to consider many variables, for example, what type of system is used, what plants you are going to grow and under what environmental conditions. Though there are a great variety of factors to consider while choosing a particular growing medium, it often comes to price, availability and personal preferences.
The most common types of growing mediums as well the description of their key advantages, disadvantages, their basic characteristics and tips on general use are specified below.
Oasis cubes
Expanded Clay Pellets
Rockwool
Coconut Fiber
Sand
Gravel
Perlite
Sphagnum Moss

Oasis cubes
Oasis cubes are lightweight cubes, which serves the best for plants propagation from seeds or cuttings. Pre-formed oasis cubes are commonly used by hydroponic gardeners. This type of growing medium features neutral pH level and can hold water very well.
Since oasis cubes are usually used at the first stages of plant growth, they are usually not larger than 2” x 2” inches in size. It is very easy to transplant such cubes into any type of hydroponic system, growing medium or even into the soil.

How do I do this chemistry conversion problem?
Vanillin is the substance whose aroma the human nose detects in the smallest amount. The threshold limit is 2.0X10^-11g per liter of air. If the current price of 50g of vanillin is $112, determine the cost to supply enough vanillin so that the aroma could be detected in a large aircraft hangar with a volume of 5.0X10^7 ft cubed.
google: liter in a cubic foot gives: 1 cubic foot = 28.3168466 liter
5.0X10^7 ft cubed @ 28.32 litres / ft3 = 1.416 e9 litres
================================
1.416 e9 litres @ 2.0X10^-11g per liter = 0.02832 grams of vanillin
0.02832 grams of vanillin @ $112 / 50 g = $ 0.063
your answer is
6.3 cents
