Lighting Migro Aray

[Vlada]

GrowlightAustralia Highlights are hitting 3umols with a 390-800nm spectrum.

Hello @damien50 I have looked at HighLights 420 as you pointed it to me in another post.
And I am looking serously at them.
May end up buying both those lights and SANlight.
Here is what I also got from Dutch Passion:
"the main benefit of sanlight compared to Migro is that the leds penetrate deeper into the canopy"
Also compared to Telos (which alos penetrate deeper than Migro):
"Sanlight is somewhat more expensive but they are simply the best"
And:
"Some of our varieties grown under SANLight actually won again at the Homegrown Cannabis Cup which is one of the heighest regarded cups in the Netherlands"
It looks like Dutch Passion highly recomends SANlight which is very valuable information.
On other hand it seems they are not familiar with GrowlightAustralia Highlights but according the diyleduk those lights are among the best ones or even the most recomended ones from their website.

I am looking for more endorsments for GrowlightAustralia.
Isnt 3umols too strong for plant that requires high knowleadge in providing everything at optimum?

The 3umols/j refers to the efficiency so compared to the entry level Chinese lights, you're going to get more output for less power.

They will be my next set of lights and they cost less than the Sanlight with a better spectrum imo. I think there is real value for 2x2-3x3 spaces without the need to run UVB/660/730 except at lights out and they are on their second generation.

At Rolitup forum GrowlightsAustralia is doing good job of explaining those lights and I will do research there.
I believe those lights are among the top ones.
What I am trying to figure out is in SANlight for 2×4 grow space they recomend two Q3W lights each using 120W so total 240W with 2.7umols/j while GrowlightsAustralia for 2×4 grow space recomend HighLight 420 that use 340 or 365W from the wall with 3umils/j.
So higher effuciency of australian brand but much higher wattage as well.
Shouldnt light with higher efficiency use less wattage for equal light output of the same grow space? Beside that SANlight advice to dim their pair of lights which altogether use 240W as at full strenght those lights may be to much if not everything at optimum.
It lets me think how than HighLight 420 with higher efficiency and higher wattage can be used for the same grow space?

From what I'm reading on their RIU thread, their rep seems to know what he is talking about.

That said, more light, more watts etc.. you need to have more of everything else. Is 365w in a 2x4 gonna need co2? Certainly will need more of everything else.

Their main selling point seems to be their inclusion of IR and the decrease in flower time from it. I am just browsing tho and could be missing stuff. They also are releasing an updated version it seems soon if not already, so I'd make sure to be getting that one.

MIGRO ARAY PRO @2.37 umol/watt ppfd

I asked their support and they tell me they are using exclusively Seoul 3030 diodes(with Osram red) from now on. I like it, might actually get the Aray 4.

Some interesting info on these diodes from an Austrian company that also uses them.

SULFUR is an important secondary nutrient for plants growth and an efficient fungizide. Unfortunately it is also known to cause fast degradation of LED-Systems. Find out more...

So don't know if any of you noticed, Ledgardener made a really cool ppfd plotting machine and is doing ppfd charts now. He put the Aray 4 Pro under it, some really impressive numbers there.

I’m using the Aray4 pro, they grow big plants with tight node spacing from my experiences so far.

Hey man what height you been hanging your aray 4 in veg seems to need to be higher than the recommended plants not liking it even at 50% when 15cm from plants seems to be too strong

I start off at around 30cm and lower it down, at the moment the unit is hanging around 20cm on full power. I think genetics play a big part, some plants can take it and others are more sensitive.
