One
of the largest hydroponically grown crops is tomatoes. They grow larger,
faster and more uniformly in hydroponic systems and have quickly become
used in some of the largest agriculture producers in the world. Most
of the tomatoes in US supermarkets are grown without ever touching soil,
so it is certainly true that most people have already consumed a great
deal of hydroponically grown vegetables, however they are not limited
to large hydro-farms. It can be very rewarding to grow hydroponic tomatoes
at home, especially since they can be grown out of season, inside or
outdoors.
Hydroponically grown tomatoes are delicious and packed full of nutrients.
If you grow hydroponic tomatoes at home you can pick them right off
the vine and consume them almost immediately whether it is on a sandwich,
salad or alone. Fresh tomatoes are significantly higher in nutritional
value than ones that have been sitting in a supermarket, those tomatoes
were often picked weeks prior to being consumed.
To grow hydroponic tomatoes at home, you must first decide whether
you will be growing them indoors or outdoors. Outdoor growing requires
the least amount of work and supplies, but is limited by sunlight, changing
seasons, and freezing or hot temperatures. A basic outdoor set up requires
a pump, channels for the nutrient solution to flow down, tubing to re-circulate
the solution and a material to support the plants as they grow. Once
the system is set up and functioning, the sun will do the rest, just
be sure to check the nutrient solution daily, and replenish it when
necessary.
Colder climates and areas in the highest and lowest latitudes are difficult
places to grow outdoors, so an indoor system is preferred. Some companies’
market smaller units designed for easy home set up, sizes range from
about the size of a travel cooler, to the size of a stand alone freezer
while custom built models can be made to fill rooms or basements. With
indoor systems the entire process is controlled, you can determine the
amount of light, type of light, temperature and humidity of the grow
room.
To grow hydroponic tomatoes at home indoors requires the use of an
external light. Tomatoes prefer lots of sun, but specifically they prefer
light in the blue area of the spectrum. Metal halide lights are great
for tomatoes because they provide the bluest light, although LED lights
are making improvements in power and efficiency and create much less
heat than halide or high pressure sodium lights. Heat from the lights
has to be regulated, a hot environment is not ideal for plant growth
and in extreme cases will completely dry out and kill the plant. Fans
are essential to most indoor hydroponic systems, keeping temperature
and humidity at optimum levels.
No matter where you choose to grow hydroponic tomatoes at home, indoors
or out, it can provide a tasty and cost effective alternative to purchasing
produce from a grocery store. An efficient hydroponic system uses very
little water, and can pay for itself in only a few months.
