Yo! I was offered a great deal on an HLG 650r but I’m thinking I should get a bar style light for distance to canopy purposes since I grow in a tent..

I’m trying to decide between a Mars Hydro FC4800 and a Grand Master Tarantula Torch 480. Specs are somewhat similar. I think GM is probably a newish company. They’re out of Canada and will probably have better customer service and warranty, though I believe ultimately the lights are built in China.

The MH light has equal red to blue in the spectrum and no far red. The GM light is more red heavy and has some far red in the spectrum.

Anybody have any experience with Grand Master? Also open to other suggestions. I think the ACI EVO6 would be an option as well..

Depends on what your using it for just flowering, just veg or veg and flower.

I dunno about mars hydro it’s either then or spider farmer I read weren’t build as well I can’t remember witch it was in a discussion about lights I read but didn’t get involved in as I’ve no experience with either.

I would also think the opposite new company , less lightly to get good customer service as the bigger companies live or die by reputation and a newer one a unknown also Chinese electric’s always scare me.

I know many have no problems with Chinese lights however after a few doggie Chinese electric items one blowing up I tend to not trust them no more.

If your using it for veg and flowering then one with a more even spectrum makes more sense.

I use lumteck lights not a big massive like mars or spider farmer name but are known I like them quite a bit but haven’t got massive experience with led

I grew up with street lamps lol opps ever walked down a street and wonder why the lights didn’t work ; probably a grower had them 🤣 and mainly used hids leds are still quite new to me tbh

Well, one cool thing about grand master is that Migro recently reviewed his flagship light and recorded the “most even coverage in the world!” That’s not the one I would get but it is a good sign. You are right that the company could just disappear.. That is certainly a risk.

It would be just for flowering. I’m finding it very difficult to make a decision and pull the trigger on any one light! I found someone on Facebook that is using the same light that I’m eyeing and he loves it. In fact he prefers it to HLG which he has also used. Still can’t decide though..

From watching lots of Dr. Bugbee videos, I am skeptical that adding far red LEDs is beneficial, but that doesn’t mean the light will suck.

I also tend to be skeptical about the benefits. It's not that I think there aren't any. My skepticism arises when I think about marginal differences. In other words, is a few grams more yield worth many dollars more cost? The answer for me often is no, it isn't. Even so, I can still be drawn toward advancing technologies and chasing the next big thing. I just began a run with a new light that works with my controller, so I can adjust the light with the phone app from anywhere. I'm also curious about its capability to do dawn and dusk transitions. So, I suppose I too am attracted to advancing growing technologies.

I think I recall Bugbee claiming there was no benefit to the dusk/dawn transitions, only drawbacks, but don't quote me on that. Also, I don't take everything he says as 100% gospel but I do tend to trust his word on lighting over most people's. Having control over spectrum would be the coolest feature!

The most logical use for far red that I've seen is in the very beginning stages of vegetative growth, and perhaps then again in the last two weeks of flowering.

I dropped Mars Hydro as an option due to the fact that they have worthless customer support. Right now it's between Grand Master, AC Infinity, HLG and Vivarspectra. The first 3 are all 550 dollars or so. The Vivarspectra is only 300 dollars but seems to have a weird spectrum and the other options are all more powerful as well.

Ah, well, that wasn't the only reason I bought the light. It's just a curiosity for me. Currently, the transition is set to 30 minutes, which probably won't have much of an effect. It's part of an on-going interest I have in managing plant stressors. I'm not mentioning it much because the pursuit could indeed be futile. It's only that curiosity is one of my driving motivations for growing these wonderful plants. I can say, so far, that the plant growing under this light looks happy.

I have ran many HLG lights and they are actually really nice lights! I have the Mars fc4800 and it's nothing to call home to mom about! GrandMaster led has some of the absolute best lights ever made! Most even ppfd across the canopy! They are set out to make sure they make the best light in the market every single light they make! I would 100% get the GrandMaster light! Use code Amanda and you'll save 10%! You won't be disappointed if you end up going with GML! Also, I seen you mention customer service! Their customer service is top notch! Again, their goal is to be the absolute best led light company on the market and customer service is a huge part if that! They will make sure any questions are answered and any issues are resolved!

I just ordered the 5x5 tarantula ultimate tent light for my 5 x 10, I also run a medic grow fold 8 , optic slim line 650s and mars hydro fc8000……mars hydro won’t be seeing another dime from me. That fc8000 has melted driver connections 4x and dealing with 1 back and forth email per day in week 4 is no bueno…..that literally send u the replacement part with zero instruction……come to find out they shipped the damn thing out wired backwards which is why I was melting cords. On the 4th replaemt I wired them opposite to what it was shipped as and low and behold it stopped melting

If you’re trying to cover a 5x5 and u want 3-4+ a light u can’t really buy anything but the best…..that’s why I tell people 5x5 areas are for advanced growers.
4x4 their are dozens of lights that can cover it properly.
5x5 theirs only one and that’s their 5x5 tent light ….even mammoth and hlg have piss poor ppfd in edges and corners, when your pulling 3-4oz per square foot that shits adds up real wuick

I'm rocking a kindled 2 channel targeted spectrum on my 5x5. It's a lower price point than the evo considering the uv/it/far red being a stock feature. Drawback is only having on/off control with my ac infinity controller.

You should go with spider farmer or ac infinity probably. A removable driver is important and a bar style allows good air flow.

The ac infinity lights have terrible par coverage. Their par maps are all over the place . Will it grow ? Yes. Will you loose out 2 lbs from half that area being out of par spec? Also yes

That's more solid advice than mine. Lol. I just really wish I could use the incremental power settings with mine. Other than that I have no complaints with my less expensive light.

It’s a good light with great diodes from an awesome company it will grow sum damn fine weed. I’m just worried about my 3-4, most people growing just want to grow to blow so it really dosent need to be looked at from my perspective. But when u don’t smoke but everyone you know does….3-4 a light matters a lot lol.

I had extreamly high hopes for their ion series. All their other stuff is too dog, fans tents the whole 9….i just with these bar lights had fans in between the bars that would be baller

Hey I just noticed this post I know it was from January, just wanted to say I have hlg scorpion Diablos and in my opinion they are junk, unfortunately everybody thinks because they're made in the United States they are a top of the line light which they are not! I do not have a gml fixture at the present time but I have seen the quality of the Borg and they are second to none way over engineered which is great for the consumer! Unfortunately they are not cheap, in this situation it is true you pay for what you get!
The far red is definitely a plus, you can use it to do the Emison effect 15 minutes before lights on 15 minutes after lights off. Testing has also shown that running the far red throughout the lighting cycle produces more trichomes and resin as long as you keep the far red and the white Channel within 10% of each other it won't promote excessive stretching! More is waiting to be learned as testing continues! Bar lights of the way to go, panel lights are old technology... this is just my opinion! ✌️ 💨 👻

That was my #2 light choice. Glad I passed because I have minimal complaints about my choice.

Hi, Ijust noticed your post from January, GML in my opinion has the most
Extensive and innovative line of LEDs on the planet, why settle for a one channel fixture, when you can have a two channel or four Channel fixture that you can crop steer
( Borg or Borg evolution) !
Please keep in mind how versatile these fixtures are, not only can you crop steer, one example by adding the far red 730 ,15 minutes before lights coming on, and 15 minutes after lights off to obtain the Emerson effect, testing has also showed that leaving the far red on throughout the whole cycle (increasing Terps and resin) during both veg and flower to control the stretch by keeping the white and red channels within 10% of each other! You can also add more blue to spec. during veg to
build a vigorous healthy plant, as far as roots, stems and leaves. This will help you if your plant stretches too much and you need a shorter bushy plant!
Lighting Companys HLG, Spider Farmer, Mammoth and Mars Hydro goes ,there one Channel/6 panel No Frills old technology
BIG waste of Time and Money ! Bar lights have been proven to have more of an even spread of lighting across the canopy.
I can truly say, by seeing the plants! They are much happier praying under Grandmaster LEDs! The name of the game is to have vigorous /happy plants.
one last point, I do not really care how efficient the light is as far as operating cost goes and yield I want to obtain the highest quality cannabis possible! ✌️💨 👻

Hello@Gmix,
I forgot to touch on one thing, what's great about these fixtures (Borg/Borg Evolution)You can Veg and Flower in the same tent/Rm!
with over 60 preset spectrums to choose and as many as 500 plus custom spectrums!
Theses fixtures are second to NONE.
I have been following Grandmaster level since 2017 he also had the distributatior rights for hlg and they screw them so he opened his own light company, and has taken the lead!
