  Yup yup!

For that price you could have gotten a proper LED light like you were planning on building! :rofl:   I managed to snag a 180w for $73 :shh:   But I have no other input since I haven't used them before. HID might work better for you since you need the heating too, but I'd still be careful about...

  Let us know how it goes, I'd be interested in pics and a grow log.   I've debated going all white LED to see if there is a noticeable difference. Don't forget you are going to probably need a heatsink for those LEDs

  That was an interesting read, they also mention PAR vs lux/lumens as well: Measurements of PAR give an indication of the possible amount of photosynthesis and growth being performed by the plant. Foot-candle sensors and lux meters are inappropriate because they do not directly measure light...

  You've got the right idea. Be careful with power supplies, they can EASILY kill you if you don't know what you are doing, or attempt to modify them/open them.     I'm an engineer and I understand efficiencies better than you might think, I think I'm qualified to chime in on this topic.  ...

Thrips? http://en.wikipedia.org/wiki/Thrips

  True, but with "white" LEDs really being a combination of blue, green, and red light, I'd be curious to know how efficient they really are at producing a true white light. I can imagine that some of the efficiency is lost by producing the red light to adjust color temperatures. I just like...

  I guess a better question would be how large is your plant, and how many plants do you have/want to keep? If it is only a couple mature plants I might suggest looking for a "UFO" solution around 50-90w as it looks like they are easy to hang and would provide sufficient light for a medium size...

  Well, let me rephrase that. The WAY that efficiency is measured for ambient or direct lighting doesn't have significance in growing plants, as I mentioned earlier. Lumens is irrelevant when comparing a white light source to say, red or blue. http://en.wikipedia.org/wiki/Luminous_efficacy  ...

  Incorrect on so many levels.     More correct, but still incorrect. This "efficiency" is based on Lumens/watt. As I mentioned earlier, lumens are not a good measure of how "good" a grow light is. Also I am not convinced that HPS and MH are more efficient than LED. I never see 1000w LED grow...

  Is this by chance me? :P   You are right about lumens not being important (though these lights are way too bright to look at directly, I will even use sunglasses occasionally if I am working on the plants while they are under the light, the indirect light reflecting off the leaves, pots, table...

Is there a possibility your peppers are cross pollinating? If they are even remotely close together you will get cross pollination unless you use something like ultra fine mesh bags on the buds before they flower, then hand pollinate.

My time to shine!   I might win the award for most expensive yet least impressive grow room!   270w and 240w LED grow lights, about $370. Folding table Extension cords Cheapo Pedestal Oscillating fan   I'm probably going to mylar my set up and add a small heater to keep the area semi warm when...

Yeah they were kinda pricey. One of them is 270W "full spectrum" which has 7 bands, no UV, and far infrared, which is pretty much useless. You really dont need a lot of bands to be effective though, only a few key bands. I paid about $200 or so for the first one.   The second light I use is a...

I solved the mystery!   These are some "old" plants. I was a negligent owner and let them sit in cups for MONTHS, rarely potting them up. I potted the one in the back left (my T-scorp) about 2 weeks ago (it was soooo root bound, there were roots everywhere!) and then BAM! It shot up and now it...

Try growing some Bolivian Rainbow. They have nice color fruit with 4 colors at the same time on the plant during ripening.   http://www.amazon.com/Seeds-Things-BOLIVIAN-RAINBOW-ORNAMENTAL/dp/B0033HFYOO

So did you end up fertilizing right away or holding off?   Lookin good, I can't wait to get my plants big enough to do that!

So I'm growing indoors and a week or so ago I noticed small white bugs squirming around in the soil of some of my plants. So I sprayed with neem oil daily for 3-4 days and didn't notice them come back.   They did look like small roaches but I wasn't sure. 2-3 days ago I noticed a small roach in...

Sorry, looks like we need to amputate.

  As an engineer I fail to see how 1oz of dried =/= 1oz powder. Unless you are losing some to the grinder or the powder flies around everywhere it should equal the dried weight.
