These can be grown without difficulty in the kitchen, cither on window ledges or by fixing up simple plastic tents just outside. If the tent is made from polythene sheets and designed in a lean-to style, it will be possible to allow hot air from the kitchen to flow through an open window or ventilator into the growing compartment, keeping it nice and warm in winter time. Suitable culinary species that do well in hydroponics include: borage, chervil, chives, fennel, garlic, horse-radish, marjoram, mint, parsley, rosemary, rue, sage, savory, tarragon, and thyme.
In growing hydroponic vegetables, salads, fruits and other edible plants in the home, the aim should be to secure as large a yield as quickly as possible from the smallest given area. With flowers, the object is frequently to obtain 'massed bank' effects. For foodstuffs, we normally like to have constant supplies and one way of achieving this is to sow a succession of crops, having another ready to use as soon as a previous and earlier lot is exhausted. Careful planning and a little forethought are all that are needed to get such results. As mentioned before, spacing between plants in hydroponics may be reduced, by as much as fifty per cent, as long as light availability is assured. This also assists in the production of higher yields from limited space.
