Question:

Hi Keith, this is Elliot. I just purchased your book How-to Hydroponics. I bought it from Barnes and Noble and read it cover to cover. Great book, great information and awesome DIY designs. I was thinking of making the Aerospring System and was wondering if I could use an LED-Grow light. What are it's advantages and disadvantages? Sorry if LED grow lights aren't your area of expertise. Thought I'd try because they are so energy efficient!!

 

Answer:

I've used them with the following results:

60w 7 color LED
vs.
2 x 24w T5's

Results clearly favored the T5's measured in terms of overall size and
biomass of the plants grown separately under each light.

$150 LED vs $75 Flourescent

My advice, 250w MH or HPS over an Aerospring size garden and you'll
never wish you bought an LED.
