Prof Gert Venter explains the benefits and disadvantages of semi-hydroponic structures.

While hydroponic farming has been around since the Middle Ages, many developments over the years have made it far more efficient and affordable. Prof Gert Venter explains.

The most important variable affecting plant growth is light exposure, and it is therefore important to measure the amount of light your plants receive. Prof Gert Venter explains how this is done.

Seawater greenhouses may be the answer to the world’s water scarcity problem, says Prof Gert Venter.

About 70% of the earth is covered with surface water, but 97% of this is seawater. With only 3% consisting of freshwater, and less than 1% available to living organisms, hydroponic production can play an important role in reducing agricultural water usage, says Prof Gert Venter.

The saying, “If you fail to plan, you plan to fail” is certainly applicable to intensive farming systems such as hydroponics and aeroponics. Planning should encompass climate control, handling, processing, value-adding and marketing your products, writes Prof Gert Venter.
