HGL Technology 336X & Ultraviolet Surround - LED Grow Lights - International Cannagraphic Magazine Forums

Phaeton · 01-11-2012, 07:56 PM

The lights, 5 each HGL 336X-PRO growlights, 500 watts at the plug, arrived yesterday.
20 Reptisun 10, 20 Naturesun 2.0, and 30 Florasun/Redsun 48" fluorescents comprise the 8' diameter surround. The Zilla Desert 50's flunked the spectrum test and are in the 'donate' pile.

I had a longer post with pictures last night, but the site had "internal server error" and lost the thread. If this short post takes, then I will add the pictures and descriptions again.

/tagging this thread, great stuff!

I followed your last thread and am wondering if you ever calculated just how much lower your yields were with the supplemented UVB. I noticed you said that UVB was definitely not a yield builder, and I'm curious as to just how much of an effect this had.

bring on the pics... sounds like an incredible setup!!!

Whew, taking a break, smoking some of that UVB sativa.
25% loss to stunted growth. Was it worth it?
Well....I aquired a UVB meter and the surround in the photo's contains 40 bulbs putting out UVB. Enough to maintain 175 mw inside the surround, very omnidirectional, just like the sky.

The LED's are as advertised. They are set with the tops getting 1000 umole and the lower branches are maintaining 700 umole. The HID setup had about half the depth of field, with the tops at 1000 umole the lower branches dropped to almost 400.
Once the plants stabilize the tops will get 1200 umole, pretty much the max my plants can handle. And that was on a good day, the plants start to cook with HID at that level.

The pictures are before and after the LED's were hung, lots left to do.

AMAZING !!!

I notice the units have changed from lumens to umol's in my posts. I used them myself right along, but no point in posting these numbers, most members don't have quantum meters.

Why the change? Lumens are for humens? Not much info there.

Here is what I measure:

Quantum meter, reads total PAR light (360 nm to 740 nm) in umol/mm2/ms. Shortened to umol.

UVB meter, reads UVB (280 nm to 320) in microwatts.

Blue meter, reads blue (420 nm to 480) in milliwatts.

Red meter, reads red (600 nm to 740) in milliwatts.

I special ordered no meters peaking in green/yellow (480 nm to 610), and this is the most easily understood reason why lumens are useful for comparing similar bulbs only.

The green/yellow region is what a lumen meter reads, I can get those locally for $40 and do not have to wait for shipping from a specialty house.

Comparing different types of light cannot be done using just the green/yellow wavelengths, extreme variations cannot be avoided.

So I went geek for the duration.
I give brand names of the various lights as well, personal conclusions differing from mine can be drawn if the raw data is included.

Details will be itemized when the break periods allow. As the grow gets more involved, general usage terms are not always exact enough to convey the differences.

I don't wanna be a geek, but momma said "you don't always get what you want."

Or was that the rolling stones? Mick and momma had similar lips.

Looks cool and I hope it works out for you. I have a great appreciation for a scientific approach. From that I also carry a great amount of doubt regarding LED. They fail misserably to cover the entire spectrum!!!!! Don't leave out the greenand yellow! Green is important and very beneficial to the girls.

I will follow along and hope to see where this ends up.

Regards, Azeo

Green has been discovered as a key component in photosynthesis. It actually penetrates deeper in to the chlorplasts and canopy than any other color. It drives certain photosythesis very well and can contribute to yield and quality. I will look back a few pages in the CMH thread and try to "borrow" some links to the great data/studies posted by whazzup and folks like spurr (will no one is really "like" spurr) (no offense that is a compliment to spurr!), but the data is out there and many are exploring it futher.
