Hello all,I am planning a side by side (kinda) grow experiment between Enhanced Spectrum HPS Bulbs and an array of 3 different bulbs of different spectrums from Sunpulse Bulbs. The details of my experiemnt are in the conversation so I wont go into it here.

I found some of the "scientist's" remarks intersting, some enlightening, but mostly it seems to me like he is talking down to me and to cannabis growers in general in them which is part of the reason I felt I should post.

Without futher ado...

I appreciate your desire to understand our technology and how it
compares to what was.

Anyone, not you specifically, who thinks HPS was ever good, has no grasp
of photobiology, plant science or light. HPS was never good for plants.
There's a white paper on SunPulse vs. HPS on our website, in the tech
info section I think will help you understand more.

You might also grab the Sept. 2011 copy of High Times and read an
article on light there written by a real photobiologist, so you have
another reference.

I also recommend reading a book called "Photosynthesis" by Hall and Rao.
Once you understand this data, you'll understand why HPS light was
always a problem and learn what plants really want. Plants and all
living things on Earth just want the Sun.

Our lamps have been out 13 years, and are sold internationally. The
"testing" phase of our development has long passed. I'd love for your MJ
community to understand the deeper science behind our lamps, but its a
lot of science and physics to absorb.

I can't call up Sony and ask them for a Playstation3 for me to critique.
If I asked them to send me one that I could "check out", and "let them
know what I think" in my "experimentation" - they'd tell me I was on
acid. The best engineers in the world, with the most advanced testing
gear in the world, did all the thinking so I don't have to.

We're plant people who make lighting for plants. I'd love to take the
time with you to educate you more on all of these things, but its
learned over years. If you're prepared for the journey to the truth, I
invite you along. I can show you what's mythology, whats misunderstood,
what works and doesn't work. But I can't do it in an email. You have to
call if you want to learn the deeper meanings. I teach and educate on
these sciences around the world at the highest levels. If you're in the
SF bay area, I could meet with you.

Since genetics are the random factor in all of this, results may vary.
There's no magic wand for shitty genetics, not even a lamp. The lamp is
one part of a larger equation, all things must be considered.

I want to encourage your desire to learn. If you have a science lab, a
quality light meter, a UV meter, a spectrometer, and other scientific
eqpt related to plasma and gas sciences, then you have the tools to
"test" our lamps. Without those tools, you'll be flying blind. As a
scientist, that's all I can say.

I've attached a couple of docs for you to check out. Let me know what
questions you have after reading more.

I regret to inform you that less than 1% (one per-cent) of large
scale and small scale medical growers currently use your bulbs???
And all of this despite your very expensive promotion in High Times
and other places and all of these graphs and charts that show why
your lamp is purportedly better than an HPS at producing the most
efficiently grown medical cannabis that is possible at this time.

I simply offered a chance to SHOW what it is that you are speaking
about in your graphs and charts. Something that more of as person
who would purchase one of your bulbs would care to know than the
scientists that you have working on your bulbs.

I have actually found a new challenger to all of the current market
of "hydroponic" lights that are being offered, including HPS, MH,
PSMH, and LED's so I am hoping that my results can be even more
broad and geared towards forward thinking ideas instead of the
stagnant state that the industry is in right now.

I wish you luck and will still be testing your bulbs for their
actual effect on the quality of the finished as well as live
Cannabis plants for medical consumption. I am still of the opinion
that Pulse Start Metal Halide technology is a good step moving
forward to the future of indoor gardening.

Thank you for your time and detailed response. Take care and stay
safe.

I have always felt, never used them, Sunpulse was a strange and kinda hoaky company. I do to a degree understand the thinking and science behind these lights. It is just a huge investment for what seems to be a nominal gain. We as growers are not overly interested in spending a ton of cash to get only slightly better results. If it is night and day we are talking about I am all ears(and eyes, and nose, and palate), but truthfully I have my doubts. I hope this thread moves forward I would love to know the difference. Thanks

Peace

I have a test budroom and Sunpulse 4000k was tested against Phillips 4000K CMH and Agrosun red sodium. Three separate grows, same Northern Lights clone.

The Sunpulse and CMH could have been the same light, absolutely no difference. The sunpulse is digital and the arc wanders, doesn't affect output. The CMH is magnetic, no visible flicker. The light supplied to the plants has identical effects.

The HPS did not do so well, the buds took six days longer to mature, with leaf yellowing starting three weeks in.

Context: 56,000 lumen HPS, 59,000 lumen HID. Slight advantage to HID but all the other tests I've read have been 50,000 to 30,000 advantage HPS, this is way closer.

I have done three separate tests with HPS, trying to see what level does the least damage to the plants (about 4:1 MH) but every bulb from multivapor ($16) to mastercolor ($121) outgrows sodium in my testroom.

Which is possibly why Sunpulse feels another test would not be helpful. The answer to this one never varies.

[stonedar]

their website sucks and so does their service. I tried to find out if I had a 2 lamp set up what 2 lamps to use and when to use them, I got a similar response telling me all about places I could go to educate myself on lighting. Wasn't even asking for free bulbs, I just had a spare 1000w ballast laying around and was considering buying a splitter from them. Told me that my questions were something that should be handled at the retail level. Blow me.

[Dorje113]

I have tested MH + HPS vs. Only HPS in combination and in a dual arc bulb.

I agree that it is an advantage to supplement HPS but it is a trade off. Cannabis does great with only a Hortilux HPS during flowering, so when you go with a dual arc bulb or supplement with MH, you lose those lumens in the red spectrum that are best for flowering in trade for some blue light that increases quality... in some (probably most) strains. A friend grew the same strain twice, in a dialed hydro system, 1st using Horti HPS, then Horti Super-Blue MH. I forget what yields were (sorry) but he had samples tested and the Super Blue produced 10% higher THC levels than HPS.

Currently, I use a MH in between 2 HPS bulbs with wide dispersion Magnum hoods.

I have not done a real side-by-side but I have yields of 1.4 g/W using only HPS, it's only a guess, but I doubt any other bulb is going to produce yields like that. And very few people would notice the difference in quality, IMO, but I also have limited space and am running a lot of watts per area so I don't mind throwing in a MH.

So, I think light bulb scientist is right but to what degree this translated into real world results is not clear, from what I've seen I'd expect a drop in yield and a slight increase in quality.

TWO different SUNPULSE BULBS. YES, this was in an AIRCOOLED hood.

they burn stupid hot and don't do any better then the CHEAPEST hps on the planet.....

when i emailed the pics to them, they said IT WAS MY FAULT, even without asking what my aircooled hood was and what kind of exhaust for the hood.....

Whoa those bulbs looks ugly! NEVER had any bulb I used fail in any way. The Sunpulse bulbs always caught me eye until Krunch's pics.

i found out when i was changing them to new bulbs.....

what if i didnt change them and the bulbs fired like that for a few more, days, weeks or months?

ID BE IN JAIL FOR BURNING MY HOUSE DOWN WITH A GROW!!!!!

The dude you emailed kinda sounded like he was copy/pasting bs to make his email sound educated.
