As a rule, the most important aspect of growing marijuana is increasing your yields. In fact, growers are always searching for various methods to improve production.
One of the most often used method for increasing yields is to keep your grow lights on 24/7. However, there are many downfalls to giving a plant to much light.
Actually, many specialists agree that 24 hours of light can keep a plant from efficiently completing the respiration process. Bottom line, if your plants absorb a lot of light, they will be in a constant state of photosynthesis.
In result, too much photosynthesis can lead to damage to the plant and degradation of important plant proteins.
What Happens If I Accidentally Leave the Grow Lights on for 24 Hours?
One of the most often asked question from new growers is from those who accidentally leave their grow lights on for more than 24 hours. Leaving the lights on for too long is actually a common problem.
It’s often due to a malfunction in the timer, the timer breaking, or forgetting to shut the timer off manually.
If the plants are in the vegetative phase, generally it is not an issue if they are overexposed light. Nonetheless, 24 hours of light is really not good for production.
However, overexposure to light will not kill your plants.
Some growers believe that seedlings need 24 hours of light. But in actuality, many experts recommend that you give seedlings 12 hours of light and 12 hours of dark.
On the other hand, some specialist feels that your seedlings need 16 hours of light, depending on the variety.
Flowering Marijuana Plants & the Light Cycle
All plants have growth cycles. In addition, all plants require their own particular light cycle. Knowing how much light a plant needs for a certain objective is crucial to all growers.
For example, a grower that wants to produce plants with an overabundance of blooms will constrain that plant by overexposure to light, including leaving their grow lights on 24/7.
Too much light can interfere with growth, flowering, dormancy, and fruit. However, giving a plant 24 hour lighting can make it to grow much faster.
After the quick growth stage, the plants can have normal light and dark exposure so the flowering and fruit cycle starts.
To produce a profusion of blooms, the plant needs to go without darkness and be exposed to light 24 hours a day. However, too much light can disturb the natural process of its various plant cycles such as growth, flowering, fruit, and dormancy.
The flowering state is when the buds are forming and they begin to get stinky. During this stage it is crucial that the plant get the proper amount of light.
In fact, the grow light should never be left on for 24 hours. This much light will keep the plant in a vegetative state and it will not enter the flowering stage even if it has started budding.
Actually, all budding and flowering will come to a complete stop. It is when the plant has less light that it starts to bud. In fact, when a plant has less light it causes it to flower.
Going from 24 hours of light to 18 will help your plants bloom. Likewise, some experts recommend that you give the plants only 12 hours of light instead of 18.
Best Grow Lights For Marijuana
ECO Farm Newest quantum board with daisy chain
ECO Farm LED grow lights utilize the latest in high yielding LEDs technology today-Samsung LM301B diodes, high Energy Efficiency with 2.7 umol/J, delivers powerful light output and uniform canopy penetration to resulting maximum higher yields. Running 50% less power than the HPS or other SMD LEDs or Blurple lamps.
Upgraded series growing lights have a dimming knob and light switch. A single light can be adjusted the light intensity at liberty. Multi-light Connection with unified dimming especially beneficial for large area of indoor growing and commercial planting.
Excellent full spectrum - white, blue, red and IR (3000K, 660nm and IR 760nm and UV 395nm). 3000K diodes providing more reddish light. The 660nm red and IR light is especially useful during bloom, where it speeds up flowering time and boost yields. Turn your seeds into your own supply. And the light looks fairly natural, so it's good for accurately monitoring plant health.
No Fan Noise Free. High Safety performance MEAN WELL Driver, Fair Waterproofing. Update aluminum board is thick and sturdy, doesn't put out a tremendous amount of heat, high-quality protective covers for cables; User-Friendly Packaging. Quality components mean the light lasts longer, but they also save you money.
Using the Newest high-yield LED technology-336 pcs Samsung 2835 diodes. So BP1000 LED Grow Lights achieves a high energy efficiency of 2.7 umol/J and improves the light transmittance. The LED Growing Lights consumes only 90W of power, which is 50% less than the operating power of other 200W HID/Blurple/HPS lamps, while help gets 50% higher yield harvest. The maximum output is 2.5g/w. Veg Coverage: 2 x 2 ft, Flower: 1.5 x 1.5 ft.
The Full Spectrum led grow lamp can provide everything the plants need under natural light at all stages. The powerful blue light makes the plants grow faster, and IR light is particularly useful during flowering, it can accelerate bloom time and increase yield, fill the flowers with space and obtain an amazing harvest. This can not only reduce buds but also increase yield while saving energy and costs.
A fanless design is used to provide you with a silent growth life. Using high-quality Samsung LED chips and reliable drivers, the light is also made of the LED board is passively cooled by a large-area thick aluminum heat sink. The fast-dissipating aluminum material reduces the light lost in walkways and walls, increasing the light intensity by 20%, allowing your plants to get more energy without burning the plants for maximum space.
Plants Growing Lights was designed for indoor growers, the Plant Grow Lights aim to help individual indoor growers and greenhouse growers to obtain higher yield and better quality within the budget.
