What kind of lights do you want to use?

Your choices?  CFL, T5, HD or LED? They all will produce buds but think of them this way: Good; CFL, Better; T5,  Great; HD,  Awesome; LED. After years of growing and comparing results of quality and quantity of yield versus energy cost, LED wins hands down.

As late as last year, LED lights were way overpriced but now they are reasonable and within reach of all the home growers in the world.
