"I will even take a particular sellers name (ebay) if youā??re willing to assist in the qualifing.

Might seem like pimpin'.
They frown on that around here.
But, I'll root about and see what I find.


With 90W of current draw, is the heat comparable. Iā??d always imagined that it was considerably lessā?¦.but those cooling vents on the top of the UFO look pretty serious! My electronics background reminds that watts have to equal heat somehow. Si o No

They look serious but they're just 3 small, cheap, muffin fans.
Leds don't radiate heat like incandescent lights or HPS/MH.
That's why we can have the lights right down on the canopy.
LEDs produce heat at the diode junction.
So we have to suck the heat out the back and dispose of it.


Is there enough blue in a UFO to put up a respectable veg?"

There is in the one I have.

I'm quite pleased with it and I have several homebrewed lights to compare it to. Of course vegging is easy, I've vegged under 14 Watts of R n B

Lemme get this disclaimer out of the way.
Notice:
This lizard is not an expert at anything but loafing.
I don't have "the one true way" . I'm just an old fart who has plenty of time to think about things and a budget that mothers my need to cobble together my own lights.


Got to thinking about HPS vs LED budwise, the other day.

Read some feller posit that what was missing from bi-color leds was that useless spike of yellow that sodium generates, so they started adding amber leds.:wtf::silly:


Hmm, I got a different take on it.
First.
400 Watts of LEDs will produce as much or more bud than 400 Watts of HPS.
Why bother, yah?
My goal is the same yeild with less than half the power consumed.

I don't think adding an amber or warm white emitter here and there will do very much good. (don't shoot, just my opinion)
The other difference from leds is how the lights turn on and off.
The HPS come up gradually, and when they fade to black, they radiate quite a bit of far red light.
Will adding far red at lights out produce fatter, tighter buds?
Ah dunno. But I have a small experiment going to find out.

Meanwhile we are testing some high output 660 nm. led arrays.
So far, I'm impressed.


(How 'bout your light DH?
Had enought time to compare it to your HPS grow yet?)


I used DWC for the last couple of mothers, but have started using coco for the bloomery now that I'll be SOGing many small clones instead of 2 or 3 beeg girls.
I don't have a lot of experience with either method but will offer help where I can.


I like your plan and will pull up a chair.
