Has anybody tried supplementing HPS with LED lights? I'm sure this is asked all of the time, but I can't seem to find any quality information online. I've read a few things where people dropped to a smaller HPS and supplemented with LED lights. From what I've read, HPS will give you the raw power needed, while LED in the right spectrum will help with crystal formation. Is there any truth to this? If so, what are some good LEDs to get, either with e27 bases, or diodes I can wire up myself. Thanks for any insight you can offer.
