[Review] Galaxy hydro 400w COB

[frica]

yea they are noisy, but wiring them in 6 volt works just fine.

i think you guys need to understand that this post is purely educational, i ahvent said its the best, most efficient whatever light, its cheap, and works quite well, and thats it!

i took thos pictures and created this topic to give people an idea of what this pannel could do. nothing more. i dont get why some people are automaticall sceptical, im sure i wouldve posted about a 3000 dollars american made led light everybody would thank me and say its great bla bla bla, its kind of sad, i wanted to make a review of another one of their pannel but i wont bother.

It's just tough love bro.

@jrock2000 now you know what its like to take the extensive time and effort to document a full grow, post it and get met with a bunch of dick head comments.
I think the plants and bud looks great and is on par with what I would expect from that type of light. Thanks for taking the time and spreading a real world account of your experience. You are appreciated, cheers.

Good to see you post mau. Been a while.

 

[frica]

But no joke.
Wiring to 6V may hinder cooling to the point where longevity of the lights is pretty impacted.

Those galaxyhydro lights never really had the long lasting diodes, but maybe it's a different story with the COB.
Maybe after a few grows it will be noticably dimmer.

Would have taken a lot less heat if he didn't call us idiots in the first post.

Chunky looking buds, thanks for sharing!

someone doubted it was possible to get the pictures to look whiter = stupid

someone didnt believe a 400w pannel actually uses half = stupid.

once again those comments only happened because ots a cheap chinese pannel, and once again im not trying to sell it to you guys, just sharing my experience so other people can learn from it, whats wrong with that?

appart from that thanks to the other members that were supportive i appreciate it!


as for the other pannel, the 300w ive had it for more than a year and never had any issues, all the led are still functionnal. im pretty sure they wont last as long as higher end gear though.

regarding the wiring in 6v i have a fan that blows air right on the pannel so it doesnt overheat.

some people do have to understand that some of us dont have the tchnical skills or the time to build their own pannel, nor have the money to buy top shelf gear, i am one of them and therefore this chinese pannel is a grat buy

It's just tough love bro.

fine then

Your plant looks good and you obviously have talent when it comes to growing but the end result was much less than if would have been if you used a better light. Not better as in build quality of life expectancy but the cheaper cobs do lack efficiency and about 50% of what a Cree cob produces. .7 is about 50% of what most people get using the Cree. So the math is spot on. Open your eyes lose the attitude and you can learn something from this and also help others out too. But coming here saying I told you so isn't proving anything. Smoke a bowl, sell the rest buy a mau5 kit or a timber kit and double your yield next run.

Yea

"125 grams, with less than 190w of power consumtion, and its easily possible to get better resuklts with a larger grow room ( mine is tiny) and LST, but i think its nice to see the result on a less than optimised plant...

i think the results will shut up more than a few idiots here saying chinese pannels are crap, i was really happy with this one"

This is the big problem.
0.65 watt per gram with hydroponics and then calling people idiots for saying it's crap.

cant you read that i did mention it was possible to get better results???

im calling people idiots for pointing out stuff that doesnt make sense...

0.65g/w for a 130€ LED lamp, in a very small grow room, and without LST is fine...

fine then

If you have the technical skills to do hydroponics then you have the skill to assemble a cob panel.
All intimidating at first, but really there's not much to know.

And here, if it only consumes 200 watt, we call it a 200 watt panel.
Not 400 watt, even if galaxyhydro marketing says 400.
We all know those led companies like to say their panel is "x" watt, but only really "1/2x" watt

Good to hear that you have another fan blowing on it, that definitely helps.

 

[jrock2000]

well im sorry for not knowing you were supposed to put actual consumption, my bad, i did mention it was only using 190w though... wheni said 400w i was referring to the commercial name of the pannel.

i might be able to assemble one, but some people arent. and components arent as easy to find as in the usa unfortunately

and one last thing, i dont grow weed that much, i mainly grow peppers, tomatoes and strawberries, those plant do need lots of light, the more the better, but unlike with cannabis there isnt a competition to get the highest G/W, sure higher yields is of course nicer, and efficiency is nice but its not everyones aim. some people just want a cheap, sufficiently efficient light that doesnt heat too much, and if you dont want to assemble it, its a great choice!

First time I've EVER seen someone's blurple light magically become white light.
@HydroRed @Hybridway @Big smo @Rahz @Growmau5 @robincnn @a mongo frog

Real talk, this is why you get so much shit around here. You are confrontational, negative, and ignorant all at once.

@jrock2000 you shouldn't call people idiots. Nice grow, well documented, cheap light, but the problem with bottom of the barrel chinese panels isn't that they can't grow, you really have to fuck up a spectrum to make a light that can't do that. The problem is they are more expensive, less efficient, and less reliable than bargain basement HPS options, so what is the point?

for me the 1st point, and the most important was heat issues, i live in a small flat, and it gets hot really quick, an hps lamp heats too much, only option was to get a 150w, i already did, and got significantly lesser results, not mentionning that you do have to get a MH bulb for grow, and you do have to change those bulbs, and in the long run it is more expensive in my actual setting.

and once again im not trying to sell them.

You said the results will shut up retards who call it crap.

0.65g/w isn't anything that shuts up people.
People call those lights crap precisely because the results will be around those 0.65 g/w.
People here don't want 0.65g/w, after 1/2 grows your light will have been the more expensive one.

This forum has a big DIY community and you can make (much) better light for the same price.

Also the money you spend on a more expensive but higher quality Cree/Vero/Citizen COB light will be paid back with the saving you make with a massive increase in yield if the lights are the same wattage.

You're a good grower, I have little doubt in your skill with growing a plant.
But there are people who can do 1g/w fine, who are much worse growers than you are, and they are doing it in soil.

Look at this light.

https://northerngrowlights.com/collections/all/products/photon-180clu-1818?variant=21167728452

You might say, 360/330 dollar is too much.

But then you realize you should do at least 1.2 g/w with them, you're a good grower.
That's 234 gram vs 125 gram with the Chinese light.

109 gram more.

If weed is let's say worth 2 euro per gram for you.
That means you've saved a hypothetical 218 euros ith the Northern Grow light.

218 euro is about the difference in price between the quality Northern Grow Light and your Amazon/Ebay light.

So after the first growth is done, the lights are basically as expensive as each other.
Afterwards the Northern Grow Light is clearly 100% superior in every regard.

And that's assuming you can't do more than 1.2g/w, which you very well may be able to do.

If weed is let's say worth 3 euro per gram for you, then the Northern Grow Light is undoubtly cheaper than the Amazon light after the first harvest is done.

You understand now?
What seems cheaper at first, is actually more expensive.

So no, I don't think 0.65g/w for a 130 euro growlight is fine.
It may only be more cost effective if you intend to never grow again after the first harvest.

Last edit: But you've grown well.
You obviously know what you're doing with the plant.
The grow light can be better though

150 watt HPS is crap.
Same goes for 250.

Only becomes worth at 600, but maybe not even that anymore since quality LEDs have become cheaper.
1000 watt HPS is still good, DE HPS is still very good.
HPS is more efficient at higher wattages, it's crap at low shit like 150.

But like you said, in a small flat 600/1000 watt is a lot of heat.
Too much, so not an option for you.

Citizen cobs should be easier to get. Cree should be fairly easy.

Check cobkits.com they have some chips for less than $15. Two of them would be great in that light if you need to upgrade at some point.

Good looking grow. I'm sure a scrod, sog or lst would increase yield a lot. With my t5 two plants in a scrog in 7.5 gallon pots yielded double than three plants, untopped in 5 gallons.

If your happy then that's all that matters.

 

[JorgeGonzales]

You know, in fairness, a 150W HPS is very low efficiency bar, and it's possible a cheap China panel could be slightly ahead. I'm honestly not sure, but it wouldn't be too suprising.

Point still stands though.

my closet is 40cm*70cm... of course 0.65g/w is not good, but given the conditions ive grown in it is good, not excpetionnal but good, and with those pannel i wouldnt have got 2 times more !

all the things that were said before regarding efficiency and G/W is true, but once again, keep in mind the size of the closet...

and as far as weed prices go, im not selling, i barely smoke im just a hobby grower, as said earlier i mostly grow tomatoes and peppers.

and regardless, compared to chinese pannels that were available a few years ago they have come a very long way, and if you dont want to build your own pannel, theyre still a viable alternative if you want to get into leds ( which is my case), even if in the long run they end up being more expensive.

to make it simple, i think it is a good compromise

but i get your point

I understand your point too.

I personally grow more pepper than other stuff also.
Tomatoes are for the balcony. Peppers go indoor.

And I agree that those cheap China lights have improved over the years.
From the results I've seen.

With the weed prices it was more an example that you don't have to buy anymore.
But 125 gram should probably last you a whole grow cycle unless you're sharing/consuming like crazy.
