What Is Hydroponics?

Hydroponics is the art of growing plants without soil. It is the perfect way to avoid heavy, back breaking work, such as digging. Pests, diseases and weeds are generally much easier to control. Over the past few decades hydroponics has proven an ideal method for both keen amateur gardeners and commercial growers looking for an alternative way of producing plants.

How to Get More from Limited Space Using Hydroponics

Trellis Systems

Due to the exceptional growing conditions within a greenhouse many plants and vines require assistance to grow to their potential. Crops such as tomatoes, cucumbers, melons, aubergine, capsicums, beans and snowpeas require strong support and the plants must be trained up to an overhead wire or other support system. This is achieved by tying the central stem as in the case of tomatoes or main leaders as in the case of capsicum up to an overhead wire using string, or string hooks which are designed for longer-term production of many crops such as tomatoes which may be layered over time.

Hanging Gardens

An advantage of hydroponic systems in greenhouses is the ability to use overhead space. Hanging systems such as column culture and bag culture have been specifically designed to utilise overhead space. Hanging systems have been used commercially to grow trailing and climbing plants such as strawberries, zucchinis, cucumbers and climbing beans.

Tiered Beds

Tiered beds are used in both outdoor and greenhouse operations. Tiered beds not only provide the advantages of raising plants off the ground, they also allow more plants to be grown in a specific area. A typical system is a tiered rack of PVC gullies in a NFT system.

Tips For Maximising Growth

Stopping

There is often a requirement in some greenhouse grown species to temporarily stop shoot elongation and to promote lateral branching. This process can be undertaken manually by pinching the terminal bud, however, there are now chemicals available to do this. Chemical stopping will enhance branching and prevent flowering and ultimately fruiting of landscape ornamentals. Species where stopping is practised includes azalea, clerodendron, fuchsia, gardenia, ivy, geranium, kalanchoe, schefflera, privet, holly, olive and verbena.

Various longer-term vegetable crops such as tomatoes, cucumbers and peppers are typically stopped as they reach the end of their productive life, this allows any fruit left on the plant to mature through to harvest, while vegetative growth is terminated at the top. Stopping speeds up the rate of fruit development and ripening and is a useful tool in hydroponic vegetable production. For edible crops, stopping must be carried out manually by removing the growing point as most plant growth regulator compounds are typically not permitted for use on food plants.

Trimming

All plants grow foliage that can be removed without detriment to the health of the plant. In forced growing conditions, removal of unwanted growth is required to maximise plant energies to producing a saleable product. With tomatoes, all foliage below the first truss (fruit) is often trimmed off by growers in the mistaken belief that this will allow faster ripening on the fruit. However these leaves directly surrounding the truss – both above and below are the principle producers and supplies of sugars (assimilate) to that fruit and removal not only reduces final fruit size but also sugar levels and flavour quality. It is preferable to leave at least 2 leaves below the bottom truss until all fruit are harvested from that truss for this reason. Tomato plants are typically heavy croppers and are source, rather than sink limited (source being the leaves, sinks being the fruits), thus removal of `excess’ leaves is not beneficial to the plant.

The only excess growth that should be removed from tomato plants are the lateral growths that develop in the axils of each leaf. Tomatoes are typically grown as a single leader with no side branching and regular removal of lateral growth is required.
