What are LED Grow Lights?

LED Grow Lights use light emitting diodes to emit light instead of gas

LEDs are cheaper to operate in the long run as they require less power

High-output fluorescent bulbs, however, have changed the way we approach systems like the T5, allowing them to be used even during flowering stages of growth.

The T5’s effective range is only around a foot, so a stronger light will always be a little better for flowering.

How should I choose the right LED Grow Lights?

These factors are most important: Price, Coverage area, yield, and whether the light is capable of facilitating growth during all stages of the marijuana plant life cycle
