Should Grow Lights be Left on all the Time?

If I expose my plants to light for the entirety of the day, this will hasten their growth, correct? My theory is that all I have to do to turn them into monsters is make sure the lights are on.

No, as a rule, grow lights shouldn't be left on continuously while they're being used. A cycle of light and dark is necessary for plants to achieve their full development potential. It is believed that they do, in fact, "rest" throughout the night and that they use this time to carry nutrients to their extremities while slowing their growth. This hypothesis is supported by the observation that they have been observed doing so.

Keeping this fundamental fact in mind, remember that the majority of plant species require a minimum of 12 hours of light per day, of varying intensities. The plant manuals for your hydroponic setup should have information on where and how much sunlight your plants need as they mature and produce flowers.

You can, of course, use a timer to control the length of time that the lights above your hydroponic garden are on, which will guarantee that your plants receive the ideal amount of light at all times. When you have a timer, you never have to worry about forgetting to turn things on or off since the timer will do it for you.
