Quick Answer: What Light Do You Use To Grow Hydroponics?

Most hydro gardeners use High-Intensity Discharge (HID) lights. HID bulbs produce light by sending an arc of electricity between two electrodes that are encased in glass with a mixture of gas and metal salts. The gas aids the creation of the arc, which then evaporates the metal salts, producing bright white light.

How do you choose a grow light for hydroponics?

I would recommend that you give your plants 50 watts per square foot during the vegetative stage.

Can plants photosynthesize with LED light?

Plants can survive under regular LED lights, but they will only grow under LED grow lights. Plants need a light spectrum of 400-700nm for photosynthesis to happen. This is done with a combination of blue light and red light. Hence, the regular white LEDs have little effect on a plant’s growth rate.
