This page seems to have nice offers, a 300w LED panel (with 144 3 w LED's) only costs 340£... Is this too good to be true?
There's no link, so it's hard to tell if it's too good to be true based on it's specs.
Though specifications can tell you a lot, an actual grow journal is the best proof there is.

Im new to growing, and my first time will be hydroponically with led, so i hope it goes well, i plan to start my grow in the next month at latest. plan to use HSS led's( 2x PPF-400 90watts) and maybe t5's or some type of CFL light in combination.

I am in need of a little advice in the nutrients category( would like to use adv. nutrients liquids/powders) what nutrients do i need to grow great plant.

Does anyone know anything about the Pro-Grow LED lights? Are they good quality LED's? There are some things i dont really understand about them including why they use white, green and UV diodes in their lights? I feel like using white lights defeats the purpose of what LED's are good for, which in my understanding is to isolate only the wavelengths of light that plants use instead of all spectrum that is in white lights? Is this correct?

Just to clearify im talking about the lights from this site Hydroponicshut

I am pretty sure they are a reseller for Gotham Hydroponics if I heard right

GLH says their white diodes put out 3 wavelengths, a red, blue, and green if I remember correctly. Although the results from the "Light Lab" are coming back and I guess the specifics of the white wavelengths changed (gotta wait for site to update soon :( )

That red and blue stuff is all cannabis plants need is old and false. You can grow fine plants with just that but more spectrums help things along with potency and flavor and complexity of high, as well as the vegetation part. White is excellent because it is multiple colors, all of which get used. UV is useful to bring out potency and complexity in the high.

I'm sorry to say, you did not hear right.
They are a completely different companies, who don't seem to get along too well.
That's because Hydrohut makes theirs on US soil with US cree diodes and chipsets yet Gotham issues a spec in some Chinese factory then gets them shipped back to the states, you could see why Hydrohut would prefer not to associate themselves...

Do you have any proof of this that i can look at about how red and blue spectrums are not all you need? And it is completely false that all colors in white light are used by the plant..

So would anyone recommend the Pro-Grow series over GLH lights? These are the two companies im trying to decided between.

I think they are as good as each other but GLH has seen more people doing journals on them. I have done a thread on my Hydrohut panel but have not got great results due more to grower/medium error rather than the lights. IMO you would not be unhappy with either except Hydrohut is much cheaper..

Icculus, I am not an expert on this, but I have read some from people who are. I do not have references at hand, I am not that guy. If you google green light and plants you can pick some of this up, but it is deep. Also, the 'experts' disagree a bit on many things. UV is another one.

To summarize, it is far from proven that green light or uv contribute nothing to cannabis health or smoking effects. There are plenty of knowledgeable scientists that think otherwise. Sorry I just noticed you said as fact that all colors do not get used... Good luck smarty.:-P I should have ignored you.

For those interested in led lights but never got around to checking out my grow...i used a 3w 180w extreme flower led panel from advancedledlights.com, grew 2 autos and one photoperiod strain from seed and harvested 110 grams of dry bud, top shelf quality. Highly recommend this company for those looking for alternative companies to grow with.

That cool ignore me i dont need bias opinions by people who get kickbacks for giving companies sales anyways. Will not be going with Pro-Grow

Hey all, After much researching I've decided to go LED. It seems for my situation the small thermal footprint that doesn't require heavy cooling is a big plus. Also it seems that LED light is even more efficient then people realize based on most people don't subtract the watts the LED cooling fans produce from their W/G ratio. With that in mind it seems the tech will and already can advance in more efficient ways to cool single and multiple lights. I look at it like I look at cooling a CPU and can see someone perhaps water cooling multiple lights from a single low watt pump. Yeah.... I'm a modder if you haven't guessed and I just may do a little opensource R&D!

Anyway I have decided on the Blackstar line based on the smaller start up investment compared to other high cost panels. A good friend of mine who owns a local shop considers LED a waste of time but that attitude is based on his research from 2 years ago and a whole lot has changed, so I have a point to prove to him and I believe there are a decent chunk of people who don't want to manage heat, bulbs or fires. Not to mention quality... it seems LED bring the sticky to a new level. This should be fun. =)
 
I for one know that LED's work. I don't have proof because where I live but I have been building custom LED Grow Lights for a while now and as long as i use the colors that work, the lights work. Plain and simple. The individual LED's do not have markings on them so... its too easy for china men to put any shade of blue or red in there. I had to sift through a few led providers before I actually got the shade of blue and red i needed.

Check out my light!

If you're trying to prove that LEDs DONT suck, I wouldn't count on Blackstar to change his mind....
.5 gram a watt would be all that I need to prove a point but .7 should be an easy attainable goal from these lights. See the thing is start up costs... most people don't care about how great and grand an LED is if it costs a mint at startup. Sure you can try to use logic and math to show them it makes sense but without them actually seeing results with there own eyes or talking to someone they know first hand then they won't give it a second thought.

I'm primarily a supporter of the tech because of the efficiency and electrical savings and not just for grow lights but for home lighting as well. Soon the tech will be mastered and replacing a standard 60w bulb with a 6w LED unit for $5 will happen (yeah, I'm optimistic) :P

I've seen what Blackstars can do and am completely satisfied with that choice as a startup light to be introduced to LED growing. It may not be anywhere close to the best but it certainly is in the good spectrum. =)
