But doesn't lowering one set of lamps cuz of uneven canopy kind of mess everything up? Like cross over lighting and such? Ive found it better to just block a plant to get that one or few up to canopy level. Assuming everything is in the same confined room or tent.

It really depends on the situation but I was only thinking a few inches. I even have scrogs that I raise or lower my individual CXA3070's by a few inches for a low or high spot,I'm sure it doesn't make a big difference but I like to keep my lights in a certain umole level from the canopy.

It almost makes it 1 module/1plant type thing which is cool.

It won't be for everyone but for small or odd shaped areas it's should make it easy to get nice even coverage. And at this price per watt I wouldn't hesitate to fill a larger area.

How many u rec for 4x4? 6?8? And 1 more question. What drivers he usin?

I still feel the manufactures should give a sq ft to height rating and the appropriate µmole rating for each distance. It would make it much easier to determine how many fixtures you should be looking at to get the desired light level you are after.
Maybe A51 will be the first to do it?

I haven't used Veros but the ones A51 is using have the raw numbers that are very close to the CXAs I've used for over a year. Going by just that, I figure about 2.5 sq/ft per per unit and that should give me around the same results I've been getting from my CXAs. I'm sure that Jeff will supply any info you ask for,he has in the past. He may already have all the numbers and just hasn't put them on the web site yet because he's so busy or he's still gathering them with testing. I'm sure there are grows here using 4000k Vero 29 v2.0s but I haven't looked for them,I usually work from the raw numbers if I can. I think Jeff did pre-orders as way to have guys that trust the numbers or A51 to get in on the first shipment of units but he might want to give his own reason for the pre-orders.

Thought I should mention that I run just under 30 watts a sq/ft going to my COBs and if you go for max yield you may want to up that number so it may be closer to 2.2 sq/ft per light in that case,it can vary depending on your set up.

...cap you have par meter and here on the forum we make calcs on ppfd... my question its at what distance we obtains this numbers... A51 use only one cob ...the math seems to me easy for search and match the missing distance... not?...

...and obtained on non reflective walls... medium reflective walls... or high reflective walls... ...and distance from walls too... not?...

...great test model ...and great for tunning too...for my pov...;)

...verify when you can or like... im not pressing you to do it... its only my curiosity... maybe the others too...;)

pd... forget my offtopic question....

:peace:

Saludos

There are many variables to take into account and that's why I mentioned,depending on your set up. I used the example of watts per sq/ft because my COBs and the A51 COBs are so closely matched by the numbers and many don't know what PPFD is. I think you can use less watts for a scrog vs taller plants and depending on how hard the COB is driven will affect it recommended distance from the canopy and it's penetration and so on. I like to get my meter out and measure umoles at the canopy to fine tune my set up and that number can vary depending on the strain also,like I said many variables. The techies can run the PAR numbers but many people don't want to learn all that and just need some more general recommendations.

Not off topic at all my friend. A lot of the very technical people I think go the DIY route and use these calculations to great effect but the average guy doesn't want the full education and looks for more understandable recommendations from the seller. I think it helps the average guy when the tech people can help fine tune his needs depending on his set up and expectations.

I see everyone is sharing the love,this used to be a lot friendlier forum. Put some people behind a keyboard and they just blow a fuse. I was in a great mood last night before Aquaium Pants started in.

i recently stumbled about this:

#1 “Everything you hate about The Internet is actually everything you hate about people,”
#2 “The worst thing is knowing what everyone thinks about anything”
#3 “If you think The Internet is terrible now, just wait a while”

quite depressing but sums it up right. why we can't have nice things anymore

Just a quick question about W90.

It says that optimal footprint per light is 20" x 20" but only draws 95W. If you follow these stats then to fill a 5 X 5 tent nicely you would only need 3 or 4 W90 using only 285 - 380W, but recommended LED watts for that size is between 600 - 800W which means you would actually need more like 6 - 8 units?

Am I correct or not? Can someone clarify please? Thanks!
