$6 Cree's?! Your Home Depot rocks, dude. On spectrum, most people consider Neutral White (~4000k) a more than acceptable veg spectrum. It looks something like: As you can see the Blue and Amber/Red peaks are relatively equal. Here's what one Royal Blue and four 2700k LED's might look like...

Wow, you got a sick deal, man. $5 per bulb is a pretty ridiculous price. Well played! On Blue light and damage to eyes: http://www.maestrogen.com/product_detail.asp?Pid=42 These guys are using 470nm dominant wavelength LED's to illuminate silicone in a lab environment. They use amber tinted...

About 7 weeks. https://www.rollitup.org/led-other-lighting/626538-multichip-led-remote-phosphor-guess-30.html#post9585619 Plant looks like shit, I know. Mostly has to do with over nitrification and then some over P lockout. She's still doing OK and I have yet to see any hints of mold.

Damn, that looks cool. At first I thought it was going to be remote phosphor to increase the light spread, but it's just got a diffuse lens over the LED it seems like. Very pragmatic. A truly great engineering feat is to do something on a budget. Much respect.

DON'T STARE AT THE BLUE LED'S! Blue light is harmful to your eyes and can permanently damage them. That's a remote phosphor lens. Because the bulb is supposed to be 2700k I'll go out on a limb and guess the Blue LED's are 470nm. That's a wavelength, not a Kelvin temperature. The remote...

The DampRid clone brought night time RH down to ~70% AC on fan only (not sure if leaving the AC off is good, I feel there's less of a chance for mold at cooler temps). I plan to cut a couple holes in one of the lids that came with the tupperware containers and add a PC fan. This stuff actually...

Thanks! They've gotten bigger than I thought they would, tbh, I was expecting them to mainly just frost up, but they decided to do the opposite: swell and not get very frosty. Can't wait for her to finish. I've got a scope and scale in the mail coming at me in anticipation. :fire: She smells...

Idk, there's not a whole bunch of room in there, if you start training them for more branches (are you training them in any way?) it could get unmanageable quickly. I'll wait for others to respond who probably have more experience, but looking at what you've got going right now I'd try to let...

Some nice roots you got there, man. Well done. Can't wait for them to grow a bit more, it's gonna be a jungle in there. Diggin' the setup.

Beginning of the 7th week within the next few days. RP spot light only Merry panels only Bud shots Made a DampRid clone to help with high RH. Went from ~45% day, 99% high at night to ~30% day, ~75% high at night. This shit works. I bought 3lbs of industrial grade Calcium Chloride off...

Nah, he used a 10W driver as a test using five LED's in series. It was the driver meant for and wired up to the full string of 10 that was flashing. Good to see you got it working, jimjim, light looks killer.

It's also a possibility that the center of our galaxy emits an undertone of energy that shapes/molds matter over time via string theory frequency modulation and for whatever reason "wanted" marijuana plants to exist. That could take any amount of time. Think of our supermassive black hole as...

Idk, it sounds like you're overloading the driver, yet everything seems to match up. I'd contact the seller that you got the driver from and tell them your issue.

Check your wiring again (the ones at the ends). Is everything right?

http://electronics.stackexchange.com/questions/52999/why-is-my-constant-current-source-led-driver-pulsing Wrong driver? Check the math again.

I have to... :oops: Many (most?) Christians also believe in "science," lax123, you'll find people like that at every extreme. JMD: There's actually a lot of controversy in the scientific community on evolution, its mechanism(s), and fossil dating discrepancies. I'm no anthro/paleontologist...

Loooool. If this was the new thread:

The window AC dumps condensation into a Rubbermaid roughneck tote. No idea how many gallons the roughneck is, but it's quite a bit (37gal?) and it fills up at least once every week if left on during lights off. The AC unit is removing quite a bit of moisture, but obviously not enough, especially...

The LED's are doing all the work? The second two threads are 100% LED grows, of course they are. HPS is Yellow/White, Philips CDM is White, the sun is White, some LED's are White, LEP is White, fluorescent is White, and all flower perfectly adequately. I'm not quite sure what kind of proof...

I'm sorry, it's like we're egging each other on. Almost everything you say makes me angry. So did you not go through those last two threads I just posted? There are plenty of pics.
