You got way more blue than red in your mix. I'm not saying it wouldn't work because it might. I would do at least 4 Floras. The Fiji graph has been done. Flip back a few pages :). It covers the entire blue spectrum and has a 6% red 610nm spike. So very little red, but it is something. 6...

I purchased some Sylvania Gro-Lux T5 HO to try out from overseas. I have to say they put out a real nice color. Probably a good veg bulb. Here is a photo of the Sylvania Gro-Lux sitting next to a Flora Sun and a Coral Wave. Photo is as follows from left to right, Coral Wave, Flora Sun...

I've been thinking. When you look at the photosynthesis spectral absorption graph, plants utilize the far red much more than the near. Such as, they use 660nm much more than the 630nm. This being said, if you only had one red wavelength to choose from could you get away with less 660nm than...

Has anyone tried the california orange strain? Is it decent?

The T5 grow I'm doing has 130w of plant grow side lighting as well. So 562w of T5. Then when I add the UVb it will be an additional 108w which puts it at 670w. I think it's a fair comparison considering the T5's consist of a more "exact spectrum." Yes, very fair. :) I can't wait...

Update to room #2, 400w HPS super hortilux, and a 400w MH super blue hortilux. I took out the CMH and the dual spectrum because I think these are higher quality bulbs, This bud shot was NOT taken with a flash, this is how it actually looks under the 2 lights. Since this covers more of a full...

Lol, I posted this the other day. Go back a few pages, trust me. I have nothing to gain by proving a valid point. I am as intrigued by these experiments as everyone else. I have noticed a general trend from everyone and from the last 10 years that I've grown, that plants grown under HPS...

CMH's use a magnetic HPS ballast only. Here is a shot of a leaf comparison I posted the other day. HPS grown leaf on the left, PUR T5 leaf on the right. What differences do you notice?

I agree about the HPS/UVb. HPS is just not a good stand alone light source. If there was a HPS bulb that emitted more of a reddish spectrum instead of the yellow I would be all over it. But we can only use what exists. I think that a HPS/MH blue/UVb in a 3:1:1/4 would be a good combo, but we...

I will try explaining one more time. Again, the carbohydrate statement was a metaphor. And the reason the HPS grows big buds is because they have a high intensity in the yellow spectrum which is close to the red spectrum. The red spectrum is responsible for leaf growth. But, that's what you...

Now try adding some 420nm, 440nm, and some 660nm wavelengths to your HPS and see what happens. The reason the HPS grows mammoth buds is because of their intensity in the yellow spectrum. It's close enough to the red spectrum that the plants still can use it, but it's less than ideal. As time...

Hey I can take steroids and appear larger and more muscular. I see what you are saying, but bigger buds do not make a difference. It's like the jumbo baseball bat sized carrots you can buy from food distributers. They hardly taste like a carrot. Now compare it to an organically grown carrot...

Exactly my point. HPS will grow really big buds, but that's all they are, lots and lots of plant cellulose. The comparison I was making with the potatoes and rice was metaphoric. What I meant was that HPS is like a simple carb, a starch, the way white rice is to us. The HPS will produce a...

They might be lacking in magnesium. I don't see a whole lot of dark green leaf curl that would be present from over-feeding, but I'm no expert.

That's a color analysis, it's a program that will tell you how much blue green and red are in a photograph. I take a photo of the light reflecting off a white surface and enter it in the program so it will give me a general idea of how much of each color the light mixture is producing. It's...

You do realize that we are using special T5's that put out specific wavelengths of light right? These aren't your typical grow/bloom bulbs that emit mostly green/yellow light. The point we are making with these grows is that a person can grow better quality if not equal bud to that which is...

WHY WOULD YOU? Your results prove that you have the perfect mixture of light! The only thing I would experiment with next if I were you would be to add some UVb light for 4 hours in the middle part of the light cycle and see if you get stickier smellier buds. I've been wanting to use my...

YES!! 4 REAL THOSE ARE THE BEST BUDS I'VE EVER SEEN UNDER FLORO'S!!! A++ JOB, Gotta ask, what is your final flower bulb mixture?

What color are you using? Are all 4 of the Kessils the Magenta color or the Deep Purple or a mixture of both?? Lookin real nice.!!!

nice lookin buds man! BTW, the Fiji Purple graph has already been released. You can find it one page back. The analysis was done on a $4000 spectrometer so I wouldn't question the accuracy! They guy who performed the analysis has a Phd in physics so I highly doubt we need anyone else to...
