Damn you got that mainline thing down huh? looks great...I'm mainlining my newest clones and having a lil trouble considering the alternating branching from clone. But seeing that post lets me know its very possible

It was the second true node clone off the seed mother so the cuts to 2 and 4 were symmetrical, and only the cut to 8 was uneven but I know what you mean, clones are more of a challenge.
Check back Friday after 10 PM eastern for the day 35 update, I'm more impressed with this plant every night when I open the cabinet.

The new 3x3 tent arrived today and is setup next to the other 3x3 with the deathstar in it. The new critical kush mainlined to 8 is in it and the two will share the Cree floods starting tomorrow morning. Should be able to move the light setup from one tent to the other in about two minutes. I'll post a pic of her under the floods in the morning.

Well it took two weeks but the deathstar has finally responded to my care and I found her this morning with leaves pointed to the lights for the first time.
First move of the lights took about four minutes but that was with powerstrip and all, I'm sure I'll cut that in half with some practice and further setup.
The critical kush fits her new home perfectly and I'll be supercropping her from the start so she doesn't get out of hand like her mother.

Almost forgot,Cree has a new bulb out now.

Holy shit. 93 CRI...
-edit-
Oh, they're filtering out Yellow light. Nvm. Still kinda cool, I guess.

My question,Is the extra 4 watts worth it?

It's the same LED just driven harder, correct? If you take the glass off both bulbs you're paying about 10 cents more per Watt. I'd go with the cheaper solution.
I want 90+ CRI, but not by throwing energy away...

Here you go, I wonder how many lumens it puts out with the glass off?
If its efficiency is close to the regular one with the glass off then it would be just a higher watt option,but you have to remove the glass.

The heated glass can shave off the protective silicone and phosphor if you're not careful.
The California rebate has a CRI stipulation that the standard Cree bulbs don't meet. My guess is no.

Hi Cap'n, what's up? I'm liking what I see so far with your new setup. I'm wondering what happens to the CRI of the newest CREEs when you take the cover off? I'm wondering if these bulbs should be left alone? Making 2 CREE light rigs soon (4 bulb) and I'm using 3 2700Ks so maybe I'll slap the newest CREEs in with them.
Noticed you asked a question in a different thread but I thought you might like this here. Or should I say I'd rather respond to it here
. IMO as mono LEDs get better with their efficacy, they'll just get better at growing. Especially as people find out what really works best. Here's an oldie but a goodie. Blue and Red have always worked it's just such a new way of growing and the fuckin predators lying to people about their LED's abilities that have been making a way to quantify growing with LEDs possible.
Nabesei Co Ltd, a company specializing in electronic parts, exhibited plants grown under LED lights in three different colors at an exhibition that took place from April 15 to 17, 2009, in Tokyo.
Plants of the same size were continuously irradiated with light from a lighting device equipped with 630nm red LEDs, a device with 430nm blue LEDs and a pink-colored LED light composed of half red LEDs and half blue LEDs.
After three weeks of irradiation, the growths of the plants were compared with one another. As a result, it was discovered that the pink LED light most effectively promotes the growth of plants, the company said.
According to Nabesei, plants do not need all wavelengths in the visible light range for their growth, but they absorb light with certain wavelengths to grow. For example, when they perform photosynthesis or come into bloom, red light around a wavelength of 660nm, which is the absorption peak for chlorophyll, promotes the growth. Meanwhile, when the plants form flower buds, blue light around a wavelength of 450nm promotes the growth.
When comparing the plants under the three kinds of light, those under the red LED light grew slower than others and were smaller as a whole. The plants under the blue LED light had fewer leaves and were spindly on the whole. On the other hand, the plants under the pink LED light had larger leaves and had generally grown in a more balanced way.
However, the wavelength ranges that affect the growth of plants are slightly different depending on the plant type. Therefore, field tests to evaluate the irradiation time and other issues should be conducted at agricultural experiment stations from now on, Nabesei said.
In line with the ban on the sale of incandescent bulbs in 2012, the company plans to focus on the application of LEDs to illumination equipment for growing chrysanthemums. The irradiation of red LED light can delay the formation of buds on chrysanthemums. Moreover, LED light keeps bugs away because the LED emission spectrum is deviated from the bugs' visibility curve.
In addition, Nabesei exhibited a completely watertight LED light in a tank. The product is also available in a bendable type, which is suitable for interior lighting and plant cultivation requiring water sprinkling, the company said.
One can argue with what they're saying about needing different spectrums but the article is for the most part dead on. Here's something about pink LEDs that shows how many ways you can do pink in a single package. Me I just mix Blue and Red
. But shit changes and and there's probably some more timely info out there.

Thanks Fran, I kinda thought it was something like that. I already have one that's kinda close to that,I ordered a 20 watt all 660 flood on ebay and they messed up and sent me one with 16 red and 4 blue,it looks more violet. They told me to keep it free and I should get the all 660 next week, it processed through china post 3 days ago.

And just a reminder kiddies, you take that cover off, you better have some respect when around them. Here's something from; http://www.designingwithleds.com/tech-blogger-has-trouble-with-led-bulb-cover/?ModPagespeed=noscript
seems CREEs original bulb has some problems with the glue getting loose and people are running them without the globes on.
"This is a horrible idea, and if the same thing should happen to your bulb, please don’t do it. The electronics in the Cree bulb are non-isolated: The cover serves to keep consumers away from the 120V ac line voltage. If you touch the electronics portion of the bulb with the cover off and the power on you risk electrocution.
The Cree bulb packaging specifically says don’t run it with the cover off. Yes, Marco says he has it in an enclosed fixture but that’s not good enough. If you want to get more into the technical issues of non-isolated vs. isolated bulbs, here’s a place to start. And here’s a tear-down of what’s inside the Cree bulb.
OK, we’ve covered the safety issue here. Next up: What about Cree bulb’s quality? I got in touch with Mike Watson, Cree VP of corporate marketing and asked him. His responses boiled down to this:
1. Home Depot has sold more Cree LED bulbs than all other LED bulbs combined, so anecdotally, Cree failures may seem to be more noticeable.
2. The failure rates for the Cree bulb are less than half the rate of any other light within its category (that is, 60 and 40W equivalent incandescents, other LED bulbs, and CFLs, etc) sold by Home Depot.
3. If any buyer experiences a problem with their Cree bulb, they should take it back to Home Depot for a replacement, no questions asked. If they prefer they can send it back to Cree.
4. You should never, ever operate a Cree bulb with its glass bulb cover off."
I've got a CREE 2700K right next to me. It's been on for hours now and I can just twist the globe off if I wanted to. I can feel the glue giving away when I twist it a bit. Lawsuits in 3,2,.......

Next thing you'll probably tell me it's not a good idea to wet my finger and stick it in a light socket to see if it's on.
Lights on in 5 minutes so I'll be posting a weekly update in a few.
