A The great thing about T5 grow lights is that you can grow anything you can grow with HPS and LED grow lights, from clones to veggies, herbs to fruit trees. And like LED and HPS grow lights, all you have to do is find the right lumen output and color spectrum for the growth you want out of your grow room.
How far should I have my LED lights be from plants?
between 12-24 inches awayIn the vegetative stage, LED grow lights should be between 12-24 inches away from the top of the canopy. During this stage, more light is needed for photosynthesis, so the light source should be located closer to the plants. As the plants progress through the flowering stage, their demand for intense light decreases.

When it's time to flower you're going to go with a 2700k bulb to give you a yellowish/white spectrum of light that stimulates flower growth.
Can LED grow lights burn plants?

How do you know if a light is too close to a plant?

Why are my T5 plants leggy?
A common nightmare with seedlings is ‘leggy-ness’ which leads to weak, elongated stems. Leggy-ness is often the result of too much heat and not enough light, a circumstance that can happen all too easily with plants placed in a windowsill or other indoor location. One of the reasons T5 grow lights are becoming increasingly popular is because they emit only a little heat and can therefore be placed just a few centimeters above your seedlings. This close proximity eliminates leggy plants. Seedlings that are bathed with blue light from a short distance will have shorter internodal lengths, resulting in stronger plants that can focus their energy on healthy vegetative growth and root development.
What is the wavelength of light that plants use?
The specific wavelength range that plants use is commonly referred to as Photosynthetically Active Radiation (PAR). All light emitted in the PAR wavelength range is absorbed by specific cells in plants called photopigments. These cells absorb this usable light and use it for photosynthesis and sugar production. The two most common photopigments in plants are Chlorophyll A and Chlorophyll B, both of which absorb light with the highest efficiency in the blue (in particular 439nm and 469nm) and red (in particular 642nm and 667nm) wavelengths.
Do T5 grow lights spread light?
Just like giving one plant the right nutrition and depriving another will result in a difference in growth, giving one plant an abundance of light and not another will do the same. One thing that T5 grow lights are brilliant at is providing an even spread of light.
How high should I hang a T5 light?
