The LED Grow Light must be used properly for optimum growth and yield. The most common mistakes with LEDs are not having enough light and not placing the light at the proper distance. If you do not provide enough light, your plants will not grow to their full potential. Similarly, incorrect light placement will also not allow plants to grow to their full potential. Placing a light too close will stunt growth, too far will cause stretching. Follow the recommended coverage areas listed on the Details Page of each light for optimal light penetration and coverage. Keep in mind that there are many variables to indoor growing with lighting being one of the most critical.

How Far To Place LED Lights From Plants In Each Stage Of Growth?
Once again, it is important to understand that there is no universal rule for how far to place LED lights from plants in each phase of growth. Different manufacturers construct their LED lights in different ways. There are multiple details to take into consideration, such as the power and angle of individual LED diodes within a fixture and the use of lenses to reflect light downwards. The best way to get that perfect distance between the light and your canopy is to consult with the manufacturer.

The chart below shows how the distance between the lights & plants needs to be adjusted based on the wattage of your lights:

Why Are LED Grow Lights the Best Option for Your Marijuana Plant?
led grow lights for indoor plants are the best when it comes to an indoor growing setup! This is because they provide a much better wattage of light compared to some of the older/traditional lighting systems (fluorescent lights/high pressure sodium lamps/metal halides) while also not carrying any harmful chemicals inside them. Moreover, they are much more energy efficient and help save electricity costs. Furthermore, LED grow lights tend to last for much longer (about 50,000 hours on an average) compared to older forms of lighting. The best option for most modern-day growers is to get panels of full spectrum LED grow lights which allow them to easily provide light to different kinds of plants through different kinds of phases of their growth.

PHOTOBIO PHOTOBIO•T 600W LED Grow Light

PHOTOBIO has a unique spectra and optical design
Through our unique spectra we are able to improve nutritional value, extend shelf life, drive more pigmentation, increase active compound production, and shorten flowering times. These spectra have been trialed on over 300 varieties of crops and have been thoroughly fine tuned and proven. PHOTOBIO believes that a fixture’s performance should be measured in real world trials rather than by how it looks on paper.
