GIRL's GOT SKILLS

[Ichabod Crane]

And So the fight begins. The Heat Wave is about to engulf the while South...

No reason to fight. I dropped my electric bill $400 a month. And I can run my rooms with up 70 degrees out side with no cooling required where as before it was a max of 35 degrees out side. I will have to wait and see if I can go above 70 degrees when that comes. I might be able to get away with just bringing in the air.

But if you are waiting for the LEDs to get better before you buy them that is like saying I am not getting a DE fixture because there will be something better and so I will stick with my T5 till then.

And if you know what to look for the LEDs are just barely above the cost of a new good quality DE.

Yup the leds running a lot cooler = less cooling needed. Another + is led rooms like it warmer then hid rooms. I run my canopy at 85 with no heat stress. This also = less cooling needed.
LED's = more $ on the front end.
LED's = less cooling needed.
LED's = no bulbs to replace.
LED's = no reflectors to replace.
Can someone help me out with the math here? I'm not very smart

Yeah but Joe you forgot that the driver only has a 7 year warranty so you might have to replace it in about 10 years. And if you get the Samsung LEDs they only have a 100,000 hour life span till they are down to 90%of their brightness. The same 100,000 hours expected life span for that Meanwell driver. So you will end up replacing them real soon you know.

Yeah by then there will be better led's so I'll just spend the replacement money on those

De lights and single end lights are just going to have to do for now... A couple of harvest and ill go all LED... That is if I auctulay ever learn to grow... know what I mean...

If you are going to do that just run the QB boards you have at a lower current and you can jump up there efficiency numbers.

All these people scrambling to get the newest chip could get the same efficiency numbers by just running more chips at a lower current. For example if you use the Samsung 301B S6 chip and run that at .125 amps it has a efficiency of 181.9 lm/wt. If you run the Samsung 561B+ S6 at .1 amps it has a efficiency of 180.5 lm/wt. That is only 1.4 lm/wt difference. Or put another way the 301B at that current is only .004% more efficient.

And the 301B is replacing the 561C you are running and the 561C replaced the 561B+. So you can get about the same efficiency numbers with a diode that is 2 generations older.

You would need to run more chips but you still get the same numbers. It works out to about 20% more diodes needed. So what I am getting at is cost dictates what you do. If the 561B+ is more than 20% cheaper you can get a cheaper light with them than with the newer chip.

Dont discount your light just because it is older because you can still run it more efficiently and still keep up with the newest lights out there. And besides you have some of the best diodes out there so they should last a long time.

 

[Ichabod Crane]

Here is another way of looking at it.

You are running the 561C S6 diode. If you ran 1764 of these over a 4x4 area say you would get these numbers.

93930 lumens
497.3 watts (not including driver loss)

If you run the 561B+ diode at the same number of 1764 you get these numbers.

93933 lumens
520.4 watts (not including driver loss)

That is only 23.1 watts more heat. Lets say you run about 450 watts less than a 1000 watt HPS. At 23.1 watts it would take over 19 of these ton just equal the heat that you save on one HPS 1000 watt bulb.

And that amount of extra power can be lost in a bad driver selection.

 

[Smokin Joe]

I've already been upgrading the drivers. I put my hlg 600h 54bdrivers in the veg room powering 6x 288 boards each and am using invertronics eud 600s 280dt drivers powering 4 boards each in flower. I'll get some numbers for ya when I get a chance.

My new Grow room with GG4 Ogkb2.0 and Gorilla Bubble... Not too shabby for a rookie right guys... thanks to everyone for helping me learn and grow my Skills...

Salve cerco aiuto!!!!.....e la mia prima hydro rdwc....volevo sapere e normale che il mio ec diurno e diverso da quello notturno??nel senso che il giorno ho un ec pari a1.0 e di notte come si spengono le luci a le si alza....anche ad arrivare a toccare 1.2 chiedo ai piu esperti e normale questo cambiamento

 

[Aspenou812]

Temps holding at 75 rh at 65 ... that's 15 plants that can be moved around... the trays are on casters sitting over a passive drain... I can pull out the center tray and access the timer box and power outlets... and I can pull the trays out very easily... they can freely spin around in there own foot print... I have direct access to every plant in the room... I have the irragation manifold built just have to get the time to assemble it

Sorry Willie... I don't understand... can someone translate please...

I wanted to know and normal that my day ec and different from the night? in the sense that the day I have an ec equal to 1.0 and at night as you turn off the lights to get up .... even to get to touch 1.2 I ask the more experienced and normal this change.

 

[RockinRobot]

If your meter readings are different with the light on than with it off then chances are your meter is picking up electrical interference from the lights.

If EC is simply rising overnight, it may just be evaporation, though 0.2EC would require a good amount of evaporation..

 

[Willy1234]

Thank you for answering me ..... RockinRobot !!! yes, actually, and only one factor that occurs at night ... so in your opinion is an issue of evaporation ?? .... Is this a problem or not? If it's a problem that you advise me to do, I thank you.

Nice build their Aspenous

3000k in lighting.. passive drain... The trays can be pulled out and rolled out of the room and spin 360 in there own foot print... Scrogs are all up and I don't have a single damaged stem.. AC and dehumidifier... This Run Is going to be much different...

RWDC can be tricky... They always looked comacated to me... I run coco in 5 gallon air pots... DTW style.... Wish I could be more helpful...

Looking real good Aspen I like your style. By the way you ain’t no rookie after what I’ve seen you grow here. I’ve got a question...you’re still growing in coco right...if so what do you have covering it?
