I got an E-mail asking what the best light for growing 'greens' is, meaning growing plants for leaves.
They asked if they needed any special color of light like red or blue.
All plants need BOTH red and blue light ALL the time. However, blue light promotes vegetative growth, so a light like a T-5 is ideal. Red light promotes flowering, but is also needed for day to day physiology maintenance in plants. A T-5 will also have some red, enough for seedlings. If you are going to flower plants, you will want a lite like an HPS, or an LED. All the LED's from HTGSupply.com will have enough blue and red for both vegetative growth and flowering.
E-mail me with any questions,
