I have some ?'s about your next LED grow. How many LED's and what size? Are you going to match your HID watts or HID lumens? I would think it would have to be actual watts to make a true comparison IMO.
IMHO, to go from a 1000W HPS to LED in your cabinet is going to make you wanna pull your hair out! LED for veg might cut it for your requirements and expectations, but I don't think they will compare for Bud cycle. Prove me wrong..... but after I weighed out the pro's and con's about LED's, I said F' it! Even though the higher end LED's are coming out with some better warranties to warrant the price difference, BUT; can you afford to be without your LED for several weeks while it is sent back for warranty repair!?? I know I sure as heck can't! I guess it is possible if you already have HID's on hand, but for those starting out and thinking of going LED, it would pose a huge issue!
PS. Flipped my grow to 12/12 today after I did a res change! Let the fun begin!(1st attempt @ SCROG! YAY!!!!)
PSS. Forgot to mention.... I am one of those "lurkers" you refer to all too often Jin. BIG Props and keep up the inspiration for that great project you are working on! Make sure you leave some spare time to expand that green thumb of yours while you are at it!
