1200 watts of floro? 1200WATTS OF FLORO??? Duh

Or 600?
3 gallon pots?
Looks good and what I'd expect. Nothing unexpected here!

Clearly your nurturing skills are on point!!

972 watts, 18, 54 watt bulbs, 2 gallon pots 8)

been growin awhile, written 2 books about it, I like experimentin

The par #'s on the illumitex I believe stay fairly consistent as you move away from the panel because you are entering the region where all the beam angles from the individual chips are overlapping. I bet that panel would kick ass for veg and growing lettuce etc. but as @Hybridway has been pointing out - that panel doesn't crank out the intensity for flowering

yeah sure, so you would need two of them

the point I am trying to make is that multiple light sources with optics gives penetration greater then HPS

that is what this whole thread is (supposed to be) about

myth busted, leds have better penetration that HPS

Very interesting. Way to be persistent with your preferred lighting.

Still bro...you're pushing a lotta ass there. 900 WATTS
2 gallon pots.

With lights on top how would a 6' plant fare at the bottom compared to something with higher spot PPFD numbers.

You're always welcome at my house to teach me some growing methods that's for sure

Woah woah. I'm riding this horse here.....

If you used a magnifying glass on an hid then it would have more penetration..... You have to know the focal point of the lens and then the light PPFD diminishes similar to every other light. So yes you're right but nothing you're saying hasn't been said.

Come on man. You're doing an impressive job there but 2 gallon pots. That puts it all in perspective. They're great for they're size....tho I don't look at donkey dicks they're not arm sized man. Not my arms anyway

A 6x6 is 44% larger than a 5x5, but it's fine because plants don't know math... right?

Oh Honorable RM3... please teach us poor saps how to grow donkey dicks... We get scared every time you leave the house.

972W of T5 in a 5'x5' gives you about ~9.72W/sqft of PAR power density at 25% efficiency.

972W of thousie HPS in a 6'x6' gives you ~9.72W/sqft of PAR power density at 36% efficiency.

Hands down, the thousie crushes the T5, and this is seen in practice by HPS growers conventionally.. Not taking in consideration how low the light intensity is in both, you could add 44% to your grow area without adding any power just by upgrading to HPS and yield ~44% more.

Also, if you're really growing with 9.72W/sqft, you could benefit greatly from adding more light to your grow area... I thought my 12W/sqft was low...

Logical.
If I have a sniper rifle that shoots at 2500fps (gun 1) and one that shoots at 1500fps (gun 2) shooting the same powder and BC (ballistic coeficency), they will perform as these lights.

Now say gun 1 has to go out to 300 meters for that round to be at 1000fps where as gun 2 only goes to 60 meters to match the 1000 fps.

That gun 1 will take 100 meters for its Bullet to reach 500fps where as gun 2 will only take 20 meters.

See my logic.

nope, photons have no resting mass they aren't bullets.

wrong again. the panel has the intensity, very close to a thousand ppfd across the canopy. The problem is the F3 spectrum.

come on dude, what are you doing marketing for kind led or smth?
how do photons get magnified? no you know what I dont even wanna hear it, photons DONT get magnified

HPS already has an optic, a reflector, we can use reflectors on COBs too and get the same results

@PurpleBudz
I have used the F1 spectrum in veg, very nice healthy leaves,internodal spacing and general bushyness

dunno for flower though I use 3000k cxa(yeah I know, im overdue for an upgrade but I just keep dropping the drive current rather than buy new cobs)

Are you saying light can't be directed? That's all a magnifier does. Ever fry ants with a magnifying glass as a kid? I guess the magnifying glass was a placebo

Lens=magnifier
