modular overkill led striplight build

[welight]

There is no active chiller, my actions are based on heat managment not necessarily cooling. There is a radiator which is inside my air intake and also a wort chiller (stainless coil) that will be burried in a pot. In addition to using extra electricity if the temperature is below the dew point you will get condensation. Effeciency in heat managment is about temperature diferential, too much and you are wasting energy, too little and, well, your hot or cold.
In short I would not start out with a chiller, I would find a way to store the heat. Think geothermal.

P.S. I take it you approve the hlg-40H-42a as appropriate drivers for the uvb/c strip?

sounds like a plan, on the driver I concur
Cheers

Hey I would be interested on you thoughts on watercooling re chiller, Im guessing thats a chiller there working as a table

I got some extrusion with built in TSLOT and made to watercool, any advice based on your experience on what sort of chiller?
I want to run our 560mm strips up to 100 watts each and run 4 x 1200mm at 800 watts, just cuz I can
Cheers
Mark

hahaha love it!


Also love those extrusions, very slick.

Domestic hot water pre heat.

...snip..sounds like you can have some serious production there.

No but I do take my hobby seriously.

Just weld on some brass barb fittings into the hole and you're off to the races.

Ever try welding brass to aluminum?

I can run water in my 185w strip light. Used a big tote in the next room for cooling and an Inkbird temperature controller to maintain 29C air temp in the tent.

THAT is thermal management!

Great build! I'm thinking of something like this for my perpetual full cycle tent. What would you think about mixing in a few 4000K modules to round out the spectrum a bit? Maybe I should just go full 3500K instead. Hmmm

If your flowering, 3000K. No exceptions.
Why do you think they're making board in 3000K with EVEN MORE added red?

 

[cobshopgrow]

you can may consider putting some 4000k on a switch in parallel to some 2700/3000/3500k, then you can play around a bit.
with my config 2x4 4000k, could work f.e., 4 alternating rows.
why not, it dont cost a fortune, its just wiring hasle.

 

[cobshopgrow]

hey people,
made some real world thermals in the 3x3 tent today which is in flower.
all nice n cool so far. 180w wall on the main 3000K and 20W on the 660nm leds.

 

[cobshopgrow]

well the critical run didnt went that well.
light, magnesium problems overfeeding, K blockage, a mix, idk.
the only healthy leaves are below the canopy.
whatever, i simply let them finish.

the buds are small, still lots of them.
smell is fine, frost also and theyre pretty ripe for beeing still below 8 weeks.

 

[cobshopgrow]

my new horses doing better, dinafem OG Kush.
i stay below 300ppfd, temps and RH arent good, low.
too much light and problems are starting for me.
thats about 70W wall over 3.33x3.33 (meter by meter).
feed is EC 1.1-1.2, perlite/vermiculite mix, dtw hempy.

front left is very lanky genetics, strange, one in the back is compact growing.

 

[cobshopgrow]

digitzed the graphs of the bridgelux eb3

and came to these results, not bad for a 3000k.

EB3 slim 3000k 80 cri

150mA 22.7% 10,17V 211,42 lpw 323,5l 1,53W

thats just the datasheet, not the real world tbc.

Phew boy, can't wait to see what that light does for ya.

 

[cobshopgrow]

went to 120w 3000k.
day 4 flower.



temp 23c, 40% RH, not that great.

 

[Rocket Soul]

Full screen, deep green and almost no purple stems, looking really good. Carefull to match intensity increase with temp increase

 

[cobshopgrow]

thanks, fear temparature is my weak spot.
lets see what temp it gives when were above 150w on the fixture.


btw, anyone have a clou of Dinafem OG kush phenotypes?
i would love to guess what i could expect.
1. compact strong stems, vigor is good, strong preflower hairs not so many shots.
2. very lanky, small leaves, looks almost like it have a gene defect., weak preflower hairs, many many shots, almost like supercroped.
3. in between these 2, more toward number 1

 

[Airwalker16]

thanks, fear temparature is my weak spot.

Leaf?

 

[fragileassassin]

Leaf?

You dont scare your plants?!

But kinda the same here. my leaf temps are mostly 70-72, in an 80F tent. Hoping the more wattage im adding brings them up some.
