It's all good P. If you don't mind me thread crapping a bit, here's how someone who seems to really know about cooling thinks.

Yeah I agree with this, don't think this panel is designed for growing "trees"............It's definitely beneficial to use a scrog/sog under this little guy(IMO)...
Post away my friend, we are all here to learn something new............So Apache Tech has it figured out with their panels, they have two fans mounted on the side drawing air out(i think)........well we will know for sure when puffenuff gets his new toy any day now.......I want pics puff!!!!haIt's all good P.

"When several devices on a circuit board generate the heat, a solution could be to use a
fan to blow air across the circuit board. Cooler air from outside the equipment can be
blown over warm components to reduce their temperature. Airflow will reduce the
effective thermal resistance of the air interface.
Careful placing of cooling fans can make a big difference to the performance. Large
objects like electrolytic capacitors will tend to block the flow and may steer the cooling air
away from areas of the PCB. If the air flows in the direction of heatsink fins, it will be more
effective. Air flowing across the fins will only cool the front and rear fins, see Figure 14.7.
View attachment 2190836
If mounting a fan at the top of equipment make sure that the air flows upwards,
with the fan blowing air outwards, so that the fan aids the natural buoyancy of the
hot air. Fans mounted in the side of equipment are much more effective if two
fans are used, one on either side of the enclosure. In a wide enclosure, both fans
could be mounted on the rear panel; one fan should blow in and the other should
blow out so that air circulates around the components inside.
Fans do have a reliability issue, so consider adding a fail-safe mechanism in case the
fan fails to operate. A fail-safe mechanism should monitor the temperature of
sensitive components on the circuit board. Driving the LEDs at a lower power or
turning them off when the temperature rises too high may be a solution."
Until someone convinces me otherwise that's how I'm looking at fans and cooling right now
Surly there is some spacers lifting the fan 5-10mm or so.
Ding ding........you're right as usual
View attachment 2191480
........id say a 5mm spacer Yeah personally id prefer it pulling the air away off the flat backing.....but I think it's irrelevant in my space as you stated...Remember we are taking something that's general and is applying it a very closed space, in this blow direction debate.
Reversing the flow in the standing rectangle would take energy to counteract the rising hot air flow.
In the box matching our lamps the space is so small it doesn't matter. And cooling directly on the
LED has first priority vs. using extra power on fan's
Can't wait for pics........As for the fans not being an important aspect to thermal management.....well that debatable
.........ZZZZZZZZZZZZZZZZZZ
Also he's got a much larger fan blowing directly at the heatsink, so it's kind of a silly argument
I think those are just for his trimmers (bonsai hero)..........oh fyi check his site, all sold out of his led panel...ha.....go figure....
My bad psua, I didn't mean that fans aren't important because they really are especially for the majority of the panel designs. It just has me thinking though: if there are panels out now that don't have fans like haight solid state for example, or when I look at the vapor cooling design by Kessil, and another company tells me the fans are just for good measure, then it seems like the fans (although useful/helpful) might not be the most important aspect of heat management. Just thought I'd offer another perspective since there is a lot of design and diy talk going around lately...which is great to see.Can't wait for pics........As for the fans not being an important aspect to thermal management.....well that debatable
Day 5 still nada on germination.......
Nah Puff I was just messing with you lol.......I agree their allot of "cool" designs going around now and the importance/use of a fan in some is just a precautionary measure...kinda like hans dropping a fan at the last moment on his panels(unless their is something he's not telling us
)...........
This is an awesome set-up. I just am infatuated with LED. wanted to go LED but was nervous about it. I think its the best option, IMO. Very efficient. Hope the BM Auto pops for you.Alright fellow led growers I will be testing Hans panel in a stealth/summer sealed room(oh oh)..........
Light: Hans Panel the specs are here http://www.bonsaihero.com/ledgrow.html I payed full price! if it sucks, Ill be the first to tell you...pics

Medium: 50% cocco/ 30% organic potting soil(microwaved/fu gnats
Ferts/additives: Organic TRF (dynamite)/ Horticultural lime granules ....mixed in the medium/ very light application
Water: Aerated tap water ph 6.6-7.1( aerating using aquarium pump/airstone, thus removing chlorine and adding high O2 levels)
Intake/outake cfm's: None!! complete sealed room(apt complex/ stealth is key) little worried about a sealed summer run(never done it before/only winter/will see)
Strain: Nirvana (lol/ shitty genetics/owner IMO) blue mystic auto(lol again, don't like autos) BUT it was free/ buddy hates them too/ good for the test maybe
View attachment 2183906
CO2 enrichment: Ha.................CANDLE........yes that right/ testing has shown in my 4x4x6 one candle brings the ppms to 1600 in a hour and maxes out at 2200 ppm (obviously with the plants the number will decrease due to consumption)and don't even think about trying this enrichment without a "flame defender", I don't want anyone to get hurt by being careless
View attachment 2183916View attachment 2183917
Enviromental control: Temp/rh/ppm(co2) meter........vital in a sealed room/ don't bother running one without a ppm meter.......
Air Circulation: 10 inch fan (4w low/8w high) over a 2x2 area.....
Light schedule: 24/0 yep, its an auto so i'm running this shit fast(germ-harvest under 9 weeks)ha will see , this panel consumes at max 64w so it's like running a standard light bulb(figure less than a pack a smokes for a month 24/7 draw)
Pots: Three gallon smart pots....
Light supplementation: None, I have a clamp light(with 5w led bulb/ha keeping it honest) to check on defs/pests/nute issues
Odor control: Two gonzo bags and a small air ionizer(1.5w)....Nirvana says neutral smell while growing....ha again will see Gipsy
Key to running a successfull stealth grow:
Don't show your grow....
Don't Tell about your grow.......(i know my seeds where given to me/ he runs a WAY larger grow than me, so it's a non issue)
Don't sell your grow......
Don't use a room/closet/cupboard were plumbing/electrical breakers/cable and internet wiring/etc. might need to be accessed!!
Well the seeds are in the ground and once popped, we begin the countdown............Thanks to all the RIU led growers for the great info, this is my first led grow/ my first summer sealed grow/ my first auto grow(lol)....so i'm gonna need your help....
On with the show:View attachment 2183923View attachment 2183924
Comments and criticisms are welcome...........Just don't tell me "yo drop an hps in there and grow some trees noob"!!
Edit: Starting out on early flowering phase(43w) since auto have basically no veg period i think(any auto experts chime in please)
No co2 until first set of leaves develop..........be safe and happy growing...
I hope so too brother grower...........stepping out of my comfort zone for this one...........ill try my best/hopefully the bitches cooperate
And If They Dont Back Up To That Bumper And Smack That MonkeyI hope so too brother grower...........stepping out of my comfort zone for this one...........ill try my best/hopefully the bitches cooperate
5mm That's not much I think I would use use a few more - depending on the fan speed and so on,,,Ding ding........you're right as usual
Day 5 still nada on germination................ZZZZZZZZZZZZZZZZZZ
Thanks but I don't like to fuck with them once in the medium..........patience grasshopper ................oh btw one came up5mm That's not much I think I would use use a few more - depending on the fan speed and so on,,,
Don't think I've ever waited longer than 2 days from putting a seed in the ground
(that had already cracked and a little 1-2mm white root peaking out)
to there was something visible sticking up in the pot.
5 days ! I would start an investigation, digging carefully to inspect the progress
the two in the other smarpot where put on a shelf above the lights(darkest area).......light flipped on (early flowering phase/43w)no co2 until first true set appears..
Gotta agree........They're pushing these so called "freebies" on us like they are doing us a great service, but in reality(through experience/ and this grow) it's "let's dump the old stock and gain customers win-win"...lol...........^^Yeah I never expect much from freebies. I got a Connie Chung and a Sour Cream and both couldn't even shed their seed casings, had weak ass stems and died soon after germing. But at least you got one going though. Patience grasshopper, indeed!
