nutrient solution

Hydroponics is the method of growing plants without soil. Instead of nutrients in the soil, plants thrive on a nutrient solution which contains the minerals that the plants need. So, rather than searching throughout the soil for minerals, your plants are able to get nutrients easily, directly from the nutrient solution. Grow media -- such as gravel, peat, vermiculite, Perlite, coco, old rubber tires, rockwool or expanded clay aggregates -- is often used to support the plants and their root systems and perhaps to hold moisture around the roots. The growing medium is not a source of nutrients in itself.

Why grow hydroponically?

Hydroponic gardening is an easy, environmentally sound way to grow a wide variety of healthy plants. It offers numerous benefits including:

Does virus vaccine increase the risk of cancer?

Lung specialist Wolfgang Wodarg has said that there are many risks associated with the vaccine for the H1N1 virus.

He has grave reservations about the firm Novartis who are developing the vaccine and testing it in Germany. The vaccination is injected “with a very hot needle”, Wodarg said.

The nutrient solution for the vaccine consists of cancerous cells from animals and "we do not know if there could be an allergic reaction".

But more importantly, some people fear that the risk of cancer could be increased by injecting the cells.

The vaccine - as Johannes Löwer, president of the Paul Ehrlich Institute, has pointed out - can also cause worse side effects than the actual swine flu virus.
