The vegetative phase (often called “veg”), is the phase of plant growth between seedling and flowering. This is when the plant forms, and your grow light and light spectrum play a crucial role in the plant’s development during this phase. Most growers prefer their plants to be short and bushy, and the best way to ensure that is by providing your plants enough of the essential blue spectrum they require during the vegetative phase. Why blue light spectrum is best for the seedling and vegetative growth phase, or maintaining mother cannabis plants: When you compare a dedicated veg grow light to a multi-phase grow light, you’ll find that not surprisingly, the multi-phase light has less blue light intensity. That’s because those lights need room for LEDs that emit both blue, and red, and sometimes more. You shouldn’t use red light spectrums (Red LEDs, or HPS bulbs) during the vegetative phase of growth if possible. The red light may encourage male plant growth, whereas intense blue light will encourage your seedlings to grow as female plants. What Distance From Grow Lights When Starting Seeds? Watts or wattage (W) - the amount of power which a piece of electrical equipment uses. LED bulbs are more energy efficient with a lower wattage, and will last longer than incandescent bulbs with higher wattage.

If you have a strong grow light above 500 watts of power, you’ll likely need to keep a larger distance between the light and your plants – a rough estimate would be 36 to 48 inches if the grow light were running at full power. Low light plants 500 - 3000 lx (for example Sansevieria, ZZ will tolerate low light, but will grow better in medium light) The difference in this phase of growth is that the light needs to be much stronger than when you’re starting seeds.LED grow lights are the optimum solution for accelerated plant development and explosive flowering. LED technology is soaring in popularity among beginner and professional growers. They're easy to use, durable, strong, cost-efficient, and offer full-spectrum light for the vegetative and blooming phases. We offer top-quality LED lights for indoor plants from leaders in the industry including Photon LED, Gavita, Maxibright or Telos, among others. You'll find the best LED grow lights in the UK! Take a look at the lights below that will provide sufficient intensity for maximum growth and development during this phase. The Best LED Veg Grow Lights: HLG 300L B-Spec As with any grow light, you will need ventilation in your grow space to keep the area cool while using this grow light. Other specifications:

Running a low powered T5 or T8 light during this phase could risk stretchy plants, which is why I recommend against this option. Strong light will keep those nodes tightly spaced during vegetative growth. There's are different types of hydroponic lights. Quite simply, plants need light to grow. The job of a grow light is to provide the correct kind of light to bring natural light to your indoor garden. This seedling grow light utilizes Samsung’s LM301H 3500K white spectrum, plus 470nm blue LEDs. Out of all the LED grow lights I’ve seen, the HLG 300L B-Spec is the most dedicated seedling and veg spectrum available. Recommended Distance From Plants: The ideal environment for keeping a mother plant in is the same as you would have for vegetative growth a temperature range of 18-27Cis fine with the difference between the high and low temps being no more than 5C ideally (eg 25-28C lights on 20-23C lights off). Humidity is important to keep an eye on as if using CDM or halide bulbs or indeed sodiums the humidity will be much lower than under LED or flourescent lighting. It needs to be 60-70%RH ideally and to keep these high levels a small humidifier such as a Mist Maker 3 or Ram ultrasonic humidifier will keep your humidity high and your mother beautiful! If you need to light a large grow space for vegetative growth, consider the Scynce LED Raging Kale 2. This grow light has the same blue spectrum, but covers 6×5 feet for seedling growth, or 3×4 feet for vegetative growth.To keep a mother plant you need to keep it in 18-24hr light but 18hr is preferable as different processes happen within the plant in the dark period that are helpful for good plant growth. Most plants use light from the sun to grow. We call that white light, but technically, white is the combination of every single color we can and cannot see. What you see in everyday life is the reflection of said light bouncing off an object.
