LED Grow Lights have an advantage for indoor gardening 

Here's a quick list of why I chose LED Grow Lights:

1. Bigger investment but more efficient - good for environment and wallet 

2. Smaller and more versatile 

3. Same Yield - debated topic as LED lights don't put off as much heat so you may need to supplement with a heater. On the other hand,  LED lights will not burn your  plants
