Yeah that's where I got most of mine. A pretty heavy discount can be found when compared to retail prices. Some friendly advice - I keep mine about 8 inches away from the tips in bloom, 10 in veg. I use the veg only spectrum for the first two weeks then switch to flowering spectrum only the last two weeks of flowering. This may seem wierd and I've heard a bunch of people say why turn off half your light during the final stages - just give it a try man. You'll be pleasantly suprised. I'm assuming you got the PG 180, as those are typically the ones found on ebay. If that is the case I would personally recommend only putting two plants max under the light, although the website says you can do three. For reference I'm a soil grower so this is probably why I can only fit two, if you had a hydro set up with the plants closer I could easily see fitting three properly.

I'm debating selling my 100w GLH ufo and my two 90w ufos to pick up another Pro Grow. Right now I'm running two of the 180s and 1 250 (last years model, now the PG 260 with a better veg spectrum).

You're going to be happy with your purchase.

Thanks for all the tips, you are correct it is the 180W. I was actually thinking of just leaving both spectrums on the whole round, but I'll take your advice and give half a shot.
I also own a Lighthouse Hydro 90W and 3x Sunshine System 28w Panels. I'm thinking this will go nicely with those to handle 3 plants without a problem.

Cheers,

yeah you're set for three, I'd use the PG for two, the blackstar for one and the 28 watters for side lighting. My closet is split in half with pretty good light blockage from one side to another. I tried leaving one side on full illumination (I too was skeptical about the switchable spectrum) and switched the other side to flowering only spectrum and saw a noticable difference for the better on the flowering only side of my grow. Since then have been switching the first and last 2 weeks of each cycle.

Not exactly a scientific comparison but convinced me enough to save a bit of electricity and give the plants what they obviously wanted.

I've done a lot of research on the LED technology.. Or mainly I've read this thread http://www.gardenscure.com/420/lighting/117772-how-build-your-diy-led-array.html
This guy knows near everything about LEDs, unfortunatly he is not so active on the thread anymore. But anyway, he has done a lot of testing, trying to find the best spectrum for cannabis. He has not found the holy grail yet, but he has found the best red and blue spectrum needed and a mix that would yield very good.
Plants would want the deep red spectrym (660nm) and the royal/deep blue (455nm) and also some white to get full spectrum (can't remember if it should be warm or cold)
In addition he says that wattage is not really important in LEDs it is the bin, (the efficiency per watt) which varies a lot in LEDs..
Now enough blabber from me, read the pages if you want to know about LEDs. It will also help you to sort out the bad chinese products..

Pretty spot on. Most quality led panels these days are using at least 6 different nm diodes and the capacity at which they are driven varies between manufacterers.

lookin good guys

No thoughts on the "Laser Emitting diode" link I posted? I could of sworn that 1000 times the brightness at half the wattage of a regular LED diode all while being 100 time smaller would turn some heads. This is for the automotive industry but I can see this being the next big thing some day.

LED grew some beautiful nugs ... best yet

That might just peel our skin clean off, sounds too intense.

nice roor man the signature on it is the same as on my bubble bottom roor that was blown over 10 years ago, funny lol same blower still blowin away with roor.

The tech is going to be used for B&W headlights and from the looks of it they are spreading the light via fiber optic blocks but how they manage to control the spread is beyond me. I would think if you can control the intensity and spread to be safe as a headlight you should be able to control it in the grow room. I wouldn't doubt however if the tech is patented and or uber expensive. :/

 

[Kaptain Kron]

if its fiberoptic kessil is doing it already with LED, they use a fiberoptic chipset for their LED its technically not an LED per say but i think your talkin about the same style tech, my kessils light compared to the blackstars feels physical like its there and u can touch it. Or i could be talkin bout somethin totaly different

Haha, I'm not passing judgment. It's hard to know what to trust on the Internet so I decided to contact her myself. Not saying, I trust or distrust her; just reporting back on what I found.

Cheers.

P.S. Talked with Mike from GrowLEDHydro last week. Hoping to get an interview with him soon about those Spectras.

Nothing personal but all i read was basically the same stuff he craps out on the website.

Light Sabre .... sign me up, I want one.

 

[PSUAGRO.]

Jesus "their" still trying to pimp Hydrogrowled lights around here.....lol.

 

[Kaptain Kron]

wowowowowow really lol

 

[PSUAGRO.]

Hey Kaptain, I see you use kessil lights....overall thoughts??
Still shopping for an led fixture....would appreciate your opinion on them (looking at the h350 btw)

thanx..

 

[Kaptain Kron]

oooooh boy h350 muy bueno when i used 3 h150's which is not quite as strong as a 350 i pulled more than i pulled off of my blackstar and the 3 h150's more effectively covered the area. I like em better less power usage for = to better results i wont garauntee better results but i can say it will equal easily a blackstar while consuming less power easily. The h350 is gonna be bitchin though man its going to replace my blackstar and single kessil im running over my AO right now.

I read over all the Kessil stuff yesterday and I have to admit I'm quite impressed. I think their spectral spinner (that rotates the lights) is a genius idea. I'm still trying to wrap my mind around the low watt draw though. Their h150s only draw 36 watts and their new powerful h350 only draws 90 watts. Comparing this to the Blackstar 500 that draws 300 watts and the new diamond series from advancedLED that draws 100 to 700 watts (depending on the model) has me wondering what Kessil knows that all the other guys don't.

It's like all the LED companies started out with low watt lights and then realized they needed more power. Kessil is the only one who isn't really moving in that direction. It probably has something to do with their dense matrix setup where they cram like 20 LEDs into a dime-sized space. Anyways, Kessil is definitely unique.

What type of Blackstar are you using? 240w? 500w?

 

[doups3]

Can anyone point me to some reading (or give me a short explanation) on why some LED grow lights are using white chipsets?

Thanks in advance

 

[Kaptain Kron]

240 blackstar, i can tell you what kessil "knows" that others dont they are in bed with DICON the number one fiberoptics producer in the country fiberoptics uses laser like LED chips to project that light SUPER far to transfer data, they basically took that led chip made it a bit bigger for us thats why it puts down so much power and the light feels like its physically there instead of just bright. I feel like i can FEEL the kessils light when i run my hand through it like the atmosphere is thicker its an illusion but one no other LED produces. However i saw some new interesting stuff come from irish boy the other day i guess the guys hes been playin with now have led's so powerful you have to keep them 30+ inches away or so for proper growth, somthing to look at but i still feel kessils going to take the cake, prices have come down, they are still a bit high but worth it IMO i love the quality i got with their light.
