Should I Use Both Veg And Bloom Switches?

With a full range of LED grow lights, you gain control over your plants’ growth from seed to harvest. Whether you’re nurturing new seedlings or helping your existing stock reach their full potential, we can help you find the right solution. With your choice of canopy lights, you have more control over your yields than ever before. With spectrum technology, you can make your plants think it’s Spring when it’s really fall and make them think it’s Summer when it’s really winter.

How do plants know when to grow or when to flower? It all comes down to these special light sensors. Your plant’s photoreceptors pick up signals from the light they receive and send that information out, so your plant knows exactly what to do. For example, as fall approaches, the sun sits lower in the sky, increasing the intensity of red light. A plant’s photoreceptors take that higher concentration of red as a signal to start producing as many buds as possible before winter sets in.

Let’s face it, if you want to grow top-quality plants in your space, you’re going to want to take full control of the growing environment. By using custom LED light panels, and following these simple guidelines, you can adjust the pulse rate and spectrum for each stage of the growth cycle.

Light spectrum effect on plants?

What is the light spectrum? Think of it like a rainbow. Each color in the rainbow has a specific purpose. In gardening, we care about red, blue, and UVB light. Although they are “colors” in the visible spectrum, plants see them differently than humans. Plants use these colors differently from each other and differently than we do!

  • UVB: When plants are exposed to UVB light, they produce more trichomes, increasing potency, flavor, and fragrance. Without UVB lights to protect themselves, plants cannot survive in the harsh sun.
  • Blue: Did you know that blue light is your secret weapon? Well, it is. You see, blue light creates an environment that makes THC more available. It allows the cannabinoids to bond with the terpenes.
  • Red: The red spectrum provides the wavelength necessary to promote flowering. However, too much red at the wrong time is counterproductive. It will encourage multilevel plant growth, which results in lower yields and lanky, unstable plants.

Which spectrum to use for different growth stages?

We asked a real horticulturist to share her insights on how to use the spectrum chart, how often to switch it up, and which shades yield the best results for different phases of growth (vegetative vs. flowering). The spectrum you select tells your plants what to do when by guiding them through the seasons. If you’re growing indoors, you have to completely recreate the sun for your plants through variable spectrum LED grow lights.

  • Seedling: Give your seedlings 24/7 light in a low-intensity grow light spectra, between 15% and 30% red and between 30% and 70% blue and white. Increase the intensity as they grow to more than two sets of leaves.
  • Clones: Keep the red to 25% and blue and white 45%, and you are more likely to get roots rather than “leggy” plants. They will have more energy to focus on the important stuff down below.
  • Veg: When added during the vegetative stage, more blue light keeps plants shorter with longer internodes. This makes it easier when trimming in the flowering stage. Keep blue and white light around 100% with less than 60% on the red spectrum, and you’ll avoid problems.
  • Pre-flower: The pre-flower stage is crucial to the success of your grow. If you give your plants too much red light, they will enter the flowering stage and produce buds instead of the upward growth that you are looking for. However, this does not mean you should avoid using red light altogether; just use it sparingly and remember that the right amount can be just enough to inspire your plants to grow bigger.
  • Flowering: Up until now, you’ve been shielding your plants from a blast of red light to prevent stretching, but now your plant needs all the photons it can get. Turn your red light spectrum—that’s red and deep red—up to 100%. This maneuver helps you get those higher-than-ever yields.
  • Pre-harvest: This is the place where you can fine-tune your grow light. Remember when we talked about blue and UVB lights and how they’re crucial to getting flowers that are ready for harvest? Well, this is where you get to decide how much blue and UVB light is going to be used. What you want to do it set each number to 100%, while going with a lower number on the red scale (maybe around 50 or 60).

What about greenhouse grows?

Growing cannabis in a greenhouse can save you a lot of money. This is because you can provide your plants with light at a lower intensity, since they are receiving much of their light and energy directly from the sun. However, you have to do some calculations to make sure that you’ve got the right mix of natural light and artificial plant lights. After all, plants need light, CO2, water, and nitrogen.

It’s important to keep the light on for at least twelve hours a day, but you might be able to get away with shorter days in summer when days are longer. There is no hard and fast rule about this, so you should experiment and see what works best for your own situation.

Don’t panic, super familiarize yourself with the guide above and then you can add supplementary lighting to boost your yields and get as much product from your plants as possible.


If you are short on light, your plants are going to tell you about it. The leaves will stretch out like crazy and you’ll notice a ton of them. If this happens to your cannabis plants, you know you need to increase the amount of light they’re getting. Working with LED lights is an easy, effective way to increase quality and profits.

If you’re planning on using supplemental LED lights in your greenhouse, be sure to choose fixtures with a slim profile to minimize shadowing. When it comes to industrial agricultural lighting, you can’t do better than VS LED lights. They use 50% less energy and drive your plants to produce an even higher quality product. That’s great if you are into growing profitable crops.
