LED flood lamps are perfect for maintaining mothers if you can swallow the cost. You can probably make your own LED spotlight for less if you're inclined to some DIY fun. Check eBay for "Mean Well LED driver Warm White" and check out the wattage you're interested in. You can buy passive CPU...

$.86/W for the 3Wx112 on eBay. Of course these aren't actual Watts, but it's getting much better. I don't think you need the Orange given the number of Warm Whites. I say add it to WW or split it between WW and Red. Lookin' good.

Astir, I believe. Something along those lines, at least. If they increase the price much I say drop it. You can make your own 100W spotlight for <$1/W pretty easily. CFL's are cool, too. The new Philips "MasterColor" series is getting some nice buzz...

Daaaaamn. Nice plant, dude. Hate to be a Debbie Downer, but that's gonna be one helluva bitch to trim, good Lord... Fun to smoke, though. bongsmilie Did you LST by adding side lighting? I'd say, "Yea, basically." There seems to be a lot of popcorn action going on at the bottom, though. I mean...

I've heard good things about those RBO panels on eBay, even specifically with CFL supplement. Why not buy two 120W panels, though? Using the BIN option those 90W UFO's are $1.22/W and the 120W panels are $1.05/W. No idea what the bid wars end up at.

Philips CDM bulbs look cool if you plan to go HID...

Cool study. Thanks for the link. Lol, why didn't you post this link in that jag off's "All Red" thread? Didn't you see it? Douche bag vomited on me. :confused: As for the study I linked, I think this is what you are referring to, right? If not care to quote it? This is sort of their...

Green promoted stretch in this study. No light was removed, only the addition of Green light. The plant went crazy thinking it was in a shaded environment and stretched to find higher light saturation areas, even though the control group was perfectly happy/healthy...

Personally, I'd use the CFL for UV. Here's what I'm feeling this moment. Likely to change with mood. 730nm : 660nm : 630nm : 2400-2700k : 4000k : 460nm : 430-440nm 1 : 18 : 2 : 18 : 3 : 1 : 2 I'm thinking the increased number of Warm Whites will take care of the reduced number of 460nm's and...

What, like a cylinder shaped RP lens that slowly rotates around the mixing chamber while also slowly changing in CCT to mimic the Sun's color change during the course of the day?

That Diamond series panel you're looking at should be very capable of 150g's per harvest.

Well, you're absolutely right, lumens don't have the last word. That said, these LED flood lamps aren't the most efficient use of your money, imo, but they are a really nice way to get your feet wet if you're interested in the technology. Again, though, keep in mind that in order to fully...

"The message you have entered is too short. Please lengthen your message to at least 10 characters."

Your interpretation of what that picture represents is 100% incorrect. Also, the key part of the quote above is "because of the increasingly poor match between air and the driver." This has nothing to do with light... I agree, we are off topic, which is what I've been trying to say. I hope...

30W at $220 is $7.33 per Watt. That's insane. You could do much, much better. May I suggest LED flood lamps? Within your budget, much higher lumen output per dollar and easy to hook up. Or stick with CFL, I mean, hey, if it ain't broke...

8/ No one? Apollo's are still relevant. I'd drop the 610nm and add another 2700k. Also, if you can, drop one of the 460nm's and add a 440nm. All of this is just imho of course. 4x4 is kinda big for two panels, though, if you ask me. You can always add supplemental lighting as funds permit...

How many Watts are these bulbs you're looking at? I'd say you'll need about .6W of LED for every 1W of HPS that you'd like to replace. Also, one of the really cool things about LED's are their directional behavior. They emit light in pretty narrow cones, whereas HID bulbs emit light in virtually...

Red light travels less efficiently than Blue? Where did you hear this? High frequency sounds are directional. Low frequency sounds expand in all directions. High frequencies are so directional that they can even be reflected off a small object whereas low frequencies will simply bend around...

Ack, sorry for the delayed response, just saw it now. I believe most manufacturers run their stuff at 50-60%. I think you're right on target with your guess. Coming from an efficiency standpoint it makes perfect sense to me. I don't even wanna think about running LED's close to max load w/o a...

What benefit is there to doing all Red LED's in your opinion? I also think stretching will be an issue w/o a bit of LST. I recommend having supplemental White spectrum bulbs or LED's on hand. Do you plan to cut clones from a flowering plant? I believe clones will root better when under veg...
