enough light
[/quote] I like this one @Tryingtogrow with the inclusion of UVA and IR spectrums. Also not see how many LED horticulture grow lights have this capability PLUS detachable driver???
I’ve been using a HYPHOTONFLUX HPF4000 480w for a couple years and it has the detachable Driver out of the box.
Hyphotonflux released a new 480w model for 2022 with the expanded spectrum that now includes the UVA and Far Red.
This Mars Hydro is the first 300w model I’ve seen with the expanded spectrum that includes the UVA and Far Red and detachable Driver. Really can reduce heat in your tent. And has a 2.8 umol/J efficacy?? 
make sure to get the extension cable for your driver.
Limited-time deal: 2022 Upgraded MARS HYDRO FC-E3000 300Watt LED Grow Light 3X3ft UV IR Full Spectrum Grow Light Bar with 1184pcs Diodes, Dimmable & Detachable Grow Lampe for Veg Bloom Flower, Achieve 2.8 umol/J
Says it only flowers a 2.5x 2.5 tho
Four lamps required, using above footprint
The light is said to cover a 2.5 x 2.5’ during flower stage. It comes up way short in coverage as well as power needed to flower a 4x4 space.
When looking at lights look closely at the PPFD maps. One caution when doing so is you hope the maps provided by the manufacturer / seller are accurate and truthful. Where possible I like to compare mfgr. representations to an independent third party’s tests.
The diodes used is the most important in terms of the energy consumed to produce the light. Samsung 301 b or h are most recommended.
Regarding PPFD maps…
what space is the map covering. 4x4 3x3 2x4 etc
Note the fixtures height above the plants
note what the PPFD is at the edges of the space you want to cover.
As a general rule you want an average PPFD edge to edge of around 750. Many want it to be closer to 1000.
I
I run 2 marshydro ts3000 for my 5x5 veg tent because like @beardless said they fall off on the edges
@beardless Well spoken Congrats, you got this, as usual thank you.
My current lights map in four quads of 4x4. Obviously, I need better lights for Christmas.
1000 watts meter measured using older LED lamps, acquired over last 10 years. Old now, like me.
I also have 2 vispectras 125 actual watts used
So if I use 2 vispectras and the mars hydro in the above pic. Would that be good in a 4*4 tent
If your sticking with Mars hydro you’d want the fc6500 for a 4x4, this will give you 100% coverage. Also note that There are two types, fc and fc-e. Fc will have the better Samsung lm301b diodes, Fc-e has the cheaper BridgeLux, hence the price difference.
You would still have an issue with coverage. Something that will cover 4 linear feet.
Within the mars line, the SP3000 covers 2x4
A top pick for a 2x4 is something like the HLG 350r or the HLG 320 XL V2 Rspec.
And they are the already out of date lm301b, there not lm301H or top tier Evo. Are they lm301b swept up from the floor or top bin. And we don’t know, crappy china company’s lie about everything.
Who knows, maybe, maybe not. What I will say is that some people can’t afford top of the line hlg, chilLed, etc. would I rather them chose a Growcraft x6, absolutely, unfortunately we can’t all have Lamborghinis.
It’s not a matter of Lambo, Chevy or Cadillac. Or what one can afford or not. It’s integrity and priority’s at a completely different level.
That mars fc 6500 is currently on sale at rightbuddotcom for 665.99. Great price.
They are authorized hlg distributor and they have scorpion for 899.00 and the diablo for 1174.00.
4 days shipping and was discreet.
I’ve heard that rightbud is not a good company to order from
They are authorized HGL dealers, would hgl have them if they weren’t. Hgl was out of what was recommended by the forum, so I Google and found them. As mentioned, very discreet shipping. No ties other than were I bought my light.
Got a quality light from them in 4 days,
Posted my picture like a proud papa.
