Age of plant: “Cuttings” can be switched as soon as desired, however, for optimum yields it is generally best to wait until the clone has a strong root system (typically 2-3 weeks old). For “seedlings”, if space (and time) permit, better yields can be obtained from a 6-8 week veg period.

How long do you leave lights on for hydroponics?
Most plants need a grow light on for at least half of the day, so about 12 – 14 hours. However, some plants need more than that, and the light intensity and light quality vary greatly between grow lights.
When should I turn my grow lights off?
The only time you should stop using lights on your seedlings is when they are outside. As long as they are inside the house, they should be under the lights. What is this? Once you’re in the process of hardening them, you can turn off the lights while your seedlings are outside during the day.
When should I change my lights to 12 12?
Indoor plants, given abundant light on an 18-6 or 24-0 cycle during veg time, require the switch to 12-12 to induce flower production. Reduction of daylight hours redirects energy flow from expanding vegetative growth into bud formation during reproduction.
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. It’s 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.
How many hours per day should grow lights be on?
How Long Should a Plant Grow Light Be Left On? As a general rule of thumb, most vegetables and flowering plants need 12 to 16 hours of light per day, with flowering plants at the top end of that range. Plan on giving most plants at least 8 hours of darkness per day.
Can plants get too much artificial light?
Duration of Light Most houseplants do well with 12-16 hours of artificial fluorescent light each day. Too little light will result in elongated, spindly growth and too much light will cause a plant to wilt, color to fade, soil to become excessively dry and foliage to burn.
Should I turn the grow light off at night?
In general, it’s recommended that turning off the grow light at night. You should not leave grow lights on 24/7. Plants need a light-dark cycle to develop properly. Check your plant guides for the specific sunlight needs of your hydroponic plants as they grow and bloom.
Do grow lights use a lot of electricity?
Grow lights don’t use as much electricity as you may think. However, since most grow lights are so energy efficient, you are getting huge amounts of light (and growing power) for your money! Make sure your grow room’s power circuit can handle the power draw.
Can you leave grow lights on 24 hours a day tomatoes?
Scientists have found a gene in wild tomatoes that enables farmed tomato plants to be grown 24 hours a day under natural and artificial light, boosting yields by up to 20 per cent.
How do you transition from vegetative to indoor flowering?
How to Transition Cannabis from Veg to Flower With LEDs
- STEP 1: Adjust to 12-Hour Photoperiod. For the first 1-2 days in flowering, just let your plants get used to the new 12-hour photoperiod.
- STEP 2: Begin to Increase Light Intensity.
- STEP 3: Repeat Until Ideal Light Intensity Reached.
Can I change the light cycle during flowering?
At this last stage, almost everything about flowering is done. So, no need to change the light/darkness cycle so much. You can keep the lights for 6 hours and the darkness for 18 hours. Based on situations, some growers decide to provide an uninterrupted 24-48 hours of darkness to induce the riping process.
How far away should LED grow lights be from seedlings?
There is no universal rule for setting the distance but it’s recommended that LEDs are placed 12 to 18 inches away from the plants. Light is among the most vital factors to consider when growing plants because it triggers the photosynthesis process.
Should lights be on during germination?
First, true enough, light isn’t necessary to germinate most seeds: the majority are perfectly capable of germinating in complete darkness. But there is a significant proportion of seeds that will not germinate if they aren’t exposed to light. This includes maybe a third of the plants we commonly grow from seed.
Do plants need to rest at night?
First up: plants. So, do plants sleep? I posed the question to several plant experts and the short answer is no, at least not in the literal sense. But plants do have circadian rhythms tuned to Earth’s 24-hour light-dark cycle, which they maintain even if they’re kept in light fulltime, just as we do.
