Does hydroponics need sun?

Light is required for hydroponics, but not necessarily sunlight. You can grow hydroponically outdoors or in a greenhouse where your plants will get all of the light they need naturally. Or, if you have indoor space with sufficient natural lighting, that will also work.

How much sun does a hydroponic garden need?

You should plan your system on having at least 14 to 16 hours of bright artificial light, followed by 10 to 12 hours of darkness every day. The darkness is just as important as the light—just like animals, plants need time to rest and metabolize.

How do you take care of a hydroponic plant?

The nutrient solution (fertilizer and water) should always be drained, cleaned and refilled at least one or two times a month. Since plants grown hydroponically do not require soil, there is less maintenance, no weeding and no soil-borne diseases or pests to worry with.

Where is the main location for early hydroponic garden?

The earliest examples of hydroponics date back to the Hanging Gardens of Babylon and the Floating Gardens of China. Humans used these techniques thousands of years ago. Although the general theory behind hydroponics remains the same, modern technology has enabled us to grow plants faster, stronger, and healthier.

Are LED lights good for hydroponics?

LED grow lights are becoming the go-to for hobby hydroponic gardeners and for good reason. LED grow lights are overall more efficient and have a longer lifespan. There are now so many different grow lights to choose from.

What is the best light source for hydroponics?

High-intensity discharge (HID) lights are the brightest, most effective option. They come in two distinct types: metal halide and high-pressure sodium. Metal halide bulbs are strongest in the blue range of the light spectrum, which is critical for stem and leaf growth.

What lights do professional growers use?

Today, the most widely used lights for professional use are HIDs and fluorescents. Indoor flower and vegetable growers typically use high-pressure sodium (HPS/SON) and metal halide (MH) HID lights, but fluorescents and LEDs are replacing metal halides due to their efficiency and economy.

How many watts do you need for hydroponics?

For high-light plants like tomatoes you will want to achieve around 40 watts per square foot for optimal growth and fruit production. For low light plants, and small leafy plants like herbs and lettuce, you will only need to achieve about 25 to 30 watts per square foot.

Can I leave my grow light on 24 hours?

A: In general, you should not leave grow lights on 24/7. Plants need a light-dark cycle to develop properly. Its believed that they truly do “rest” during periods of darkness, and probably use this time to move nutrients into their extremities while taking a break from growing.

Can plants have too much light?

Plants cannot get too much light, but they can get too much of the heat energy that comes with the light. Photosynthesis and other plant growth processes will shut down when the environmental and tissue temperature gets high enough that all the water taken up by the plant is used to cool the plant tissue.

How far away should light be from plants?

12 In general, youll want to hang your light no more than 12 away from your plants. - Remember: after 12 fluorescent lighting loses its power, so make sure you dont raise it any more than 12 above your canopy otherwise your plants arent getting light energy.
