Product Information

If you have the PPFD values, including all this information, you have a reliable way to compare lights. And you’ll know for sure how one light compares to another on light intensity. Green light stimulates photosynthesis deep within the leaf and canopy. Studies show green light contributes to carbon gain and crop yield ( 2). How Far to Keep from Plants: 24-38″ is the standard starting distance for the vegetative stage. You can move it to 18-20″ away in the flowering stage, or possibly even a few inches closer for light-loving strains.

LED grow lights come with built-in cooling systems and heat sinks which vent air up and away from plants. This can make it so that you can hang the LED grow light in your tent and not necessarily need an exhaust system to control the temperatureFor optimal results, you never want your PPFD to drop below 510 μmol m(-2)s(-1). You also never go above 1500 μmol m(-2)s(-1) at any given point of the coverage area. Otherwise, you’ll have to manually turn on/off your lights, which is a hassle, trust me. What to Look for And How to Rate LED Grow Lights

The full spectrum of wavelengths within PAR are covered by this light. Its coverage of wavelengths is the same as other high-quality white lights. Well, they use the same LED diodes as chips used in the premium lights on the list: Samsung LM301B diodes. But it also includes chips that cover the red spectrum (660nm) for the Emerson effect.

Introduction: Are LEDs a Good Choice for Growing Cannabis?

In nature, plants are exposed to the sun and are naturally exposed to the ultraviolet radiation that sunlight contains. When humans absorb UV radiation, we produce melanin to defend against the sun’s rays. Average Yields: 2-3+ ounces – keep in mind that the strain (genetics) and any plant training you do will make a huge difference in your final yields.

In practice, don’t let this stop you from getting high quality quantum board lights like from HLG. These quantum board lights are extremely high quality and significantly better than an average bar-setup LED grow light. What’s the right distance to keep your LED lights from your plants If you want tall and leafy plants, crank up the volume of blue light, and you’ll get just that. Certain LED grow lights are designed with adjustable blue light and red light dials. LEDs need to be kept much further away from plants than CFLs, which means that CFLs are better suited to short grow spaces without a lot of available height. LED grow lights generally need to be kept 12-18+” away from the tops of plants, while CFLs can be kept just a few inches away.

DIMMABLE AND DAISY-CHAIN FUNCTION– Design for the full plant life cycle. The light intensity can be adjusted by the knob. With a daisy chain design, one light can control the intensity of the other 99 lights by dimmer at the same time. No additional controller is needed. The plant growing light includes 1440pcs 3000K LEDs, 576pcs 6500K LEDs, 288pcs 660nm deep red LEDs. The sun-like light is best for indoor hydroponics and soil cultivation, such as potatoes, peppers, tomatoes, etc. PAR is the range of all the different wavelengths/colors of light that plants use for photosynthesis ( 5).
