Hey what do you use for taking your trichome pics?

i am wondering how the OriginalPoster did the double lens technique and also what the diffuser was.
also Noctua NF-P12 runs very quiet at 19,8 dB(A) and 1,68 mm H2O at 1.08W (12V, 0.09A)
so that is roughly 1/4 of the silverstone, but very quiet. so if 4 were stacked in series, the pressure would be more, but still quiet. it only takes up extra room. not true, the pressure doesn't inrease, but it may make up for lost pressure.
so in a pc case, room being important, unless there is a design to put it next to the light and pull it from the ceiling, one could get very low noise using the noctua fans in the technique mentioned above using a larger surface area, even using maybe two fans in parallel, and maybe even two in series. also the fans can be run higher than 0.09A (90mA) but not 13V and higher (the higher amps makes it more powerful and louder and still quiet compared to other fans when doing the same, for example a deepcool 120mm, i know this from experience).
also in the silverstone fans there is a 180mm fan called the SST-AP182 that can push 0.7mmH2O (500rpm) / 1.1mmH2O (700rpm) / 2.45mmH2O (1200rpm) / 6.1mmH2O (2000rpm)
with 17dBA (500rpm) / 18dBA (700rpm) / 34dBA (1200rpm)
so the 2000rpm must be real loud.
an idea for really loud running computers may be to run a rasberry pi tucked into the side headspace next to the light/lights and hooking it up to a monitor.
funny enough, if one knows about the raspberry pi and arduino interfacing, it seems the pi can code and controll the arduino so if there are people who know about that stuff they could set all sorts of controls for the biome from the desktop
like pH, temperature based triggers and humidity readings. there is a soil mousture sensor too so watering could be automated in theory.

also, about the fan stacking, here is a transcript from contacting Noctua.
Q: 'if i take two nf-a8 and stack them, they should be in series and have extra
pressure with their standard air flow/current being the same (with losses due to
pressure).
if i take a nf-a14 or nf-a15 and seal a 140mm to 80mm funnel on it and put it on
the same place the two stacked nf-a8 fans would go, does the pressure stay lower
than the two stacked ones, or does changing the channel diameter, also increase
the pressure that the fan draws?
it would seemingly get less airflow, but still better than the two stacked fans.
it would also seem to at least get near the same pressure of the two stacked fans.
better or worse (and depending on the more powerful nf-a14 or less powerful
nf-a15, i don\'t know)
i also guess the angle of the cone would effect the outcome and i am wondering
best case scenario.
lastly i am wondering, and asking, about how can i calculate this stuff on my own
like electricity and where may i find good resources (besides you experts).'''
A: ''Stacking the fans won't improve the pressure or air flow ratings significantly. Though you could consider fitting a funnel to a larger fan, but you do have to keep in mind that the funnel will have a negative impact on the ratings as well.
I'm afraid that there is no simple answer in this case and you may have to get a textbook on fluid dynamics.''
Q: ''i recommended to some people that instead of using a Silverstone FM-121, 3.26mmH2O fan, that multiple Noctua NF-P12 fans could do the job stacked and glue sealed with much less noise.
the material would just be loose carbon maybe an 25mm to 50mm, i was wondering how much it could go through and how many fans it would take to go through 180mm to 200mm.
''
A: ''
I'm sorry, but we don't have any kind of experience with this type of use.
Though I could imagine that one of the iPPC fans could fit your bill.
We're happy to provide you with data sheets if this is of any help.''
their iPPC fans are the industrial ones on their site. they are weather tolerant with IP52 or IP67 ratings.

they all run on 3 phase motors, and are more efficient,
"While Noctua’s NE-FD1 equipped NF-F12 and NF-A14 retail fans are amongst the most energy efficient fans in their classes, the industrialPPC versions with three-phase motors and NE-FD2 IC are even more efficient by around 10%: For example, the standard retail version of NF-A14 requires about 2.25W to run at 2000rpm whereas the industrialPPC version requires only 2.0W at the same speed. This further reduction in power consumption makes the industrialPPC fans ideal for various fields such as automotive industries, aeronautics or home appliances where, more and more often, energy efficiency is a key factor."
and have more torque,
" Rather than having a single reoccurring drive phase with torque dropping off in between the peaks, the motor has three overlapping phases that all contribute to the overall torque. As a result, there is much less variation in overall torque compared to standard single-phase motors."

and the noise ( 19,8 dB(A) at 0,09 A) is at 0.20A and about as loud as the Deepcool 120mm fan from the Gammaxx 300 cooler i ordered with a 100W 7 band LED chip. i originally thought the deepcool fan at 0.1A was to loud and was fiddling with available power supplies to run it to cool a transformer. the noctua nf-p12 using it's power supply was much more quiet. now, the deepcool with the 0.1A and 5 nf-p12 fans on 1A (all 12V) are about equal in noise). if all data is true, 21dB(A) is the max of the deepcool, with 0.13A and 13.2V, (over the 0.10A, 12.0V) and the nf-p12 at 0.09A, 12V (i ran it at 0.10A, 12V) is 19,8 dB(A). the effect may have to do with,
http://noctua.at/main.php?show=nf_b9_blade_design
"Basically, an increase in static pressure usually brings about higher noise emissions. In the case of the NF-B9, this problem is dealt with by adding Vortex-Control Notches to the blades' trailing edges. Due to the two notches at the trailing edge, the flows along the suction and pressure side mix more smoothly. This allows for less turbulence and velocity loss, which leads to a significant reduction in noise emission as well as increased efficiency. In order to achieve the smoothest possible transition and maximum noise reduction, the Vortex-Control Notches are rounded in shape.
NF-B9 Blade Design
In addition to optimizing the joining of the flows at the trailing edge, the Vortex-Control Notches fulfil the task of psychoacoustic optimization: Due to the Vortex-Control Notches, trailing edge vortices are split up into several smaller vortices. Thus the noise is spread over a wider range of frequencies and therefore perceived as much less annoying.
"
the psycoacoustic optimization (2nd part), which seems make the lowered decibles be percieved as lower.
meaning that if i didn't plastic weld my fans into my rubbermaid contraption, i might have been able to use louder
[NF-F12 industrialPPC-2000 IP67 PWM (0.1A so 10, 2 stacked side by side array pushing {4} and 2 stacked side by side array pulling {4})( and 2 on the CPU cooler)
or
NF-A14 industrialPPC-2000 IP67 PWM (0.18A {push 2A through each} so 5, 2 side by side array pushing {2} and 2 side by side array pulling {2})(and 1 on the CPU cooler)]
fans for the same 12W. especially if the psycoacoustic effect is doing what i think with my nf-p12 fans at 0.2A each
the fans may be $20 each and i still go for them in the per suit of excellence. it made for a good experiment and a pc case would need less air flow, and a smaller filter than what i am aiming at (a closet like scruber/classic scrubber, done better, with pc fans and put in double stacked rubbemaids or orbis straight wall nesting crates (stack pack), focusing on pressure and noise rather than airflow (LEDs that are "full spectrum" and/or wavelength specific to reduce heat and keeping heatsinks built out of the case [heat pipe CPU coolers])

If still any further assistant is needed, please feel free to let us know."
(it seems there is an amp limit here. it seems to be different with Noctua. here is a transcript with them about that.
Q: ''Is it alright to run a non PWM NF-P12 at 0.1A? 0.15A? what is the
safe limit, even if the noise goes up?
(i know the specs say 0.09A so i just wan\'t to check about squeezing more from it
in my projects with the power supplies i have)''
A: ''there is a simple answer to it: Please just don't go over 13V, this is the limit.''
my fans are NF-P12 not NF-P12 PWM, which runs on 0.05A, 12V.
i haven't asked Noctua if PWM fans can run safe on higher currents(amps)
maybe 2 Noctua 140mm IP67 (NF-A14 industrialPPC-2000 IP67 PWM) can push/pull a good scrubber well in a pc case. maybe 0.4A, ~31,5 dB(A), ~4,18 mm H2O, 4.8W and quieter than the Silverstone FM-121, 3.26mmH2O fan with 39.5dBA at 2400rpm at the same 0.4A. double or less money and two 140mm (140mm squared area [may be minus the inner circles of the rotors) fans with more torque and lower vibration an noise (slightly; however especially if the psycoacoustic effect is doing what i think with my nf-p12 fans at 0.2A each), all water and dust proof, compared to a 120mm fan that only has an adjustable controll as a highground. i hope they make a 180mm.
RANDOM, I HOOKED UP A INDUSTRIAL 120mm 3000PPC (3 PHASE ) WITH TWO INDUSTRIAL 120mm 2000PPC and i the 3000PPC broke. i guess only the same fans can be hooked up on parallel? this may be like needing to use a current mirror in LEDs in parallel.

although, i for instance ended up with a box with 12W running 5 fans and 1.2W on another. two are coolers of heatsink/powersupply. 4 are two side by side pushers, into a scrubber box, with two side by side pullers on the top. the 500mA supply for the 5 Noctua NF-P12 arrived as a 1000mA (1Amphere) so the 0.1A distribution is now 0.2A for each of the 5 fans.

and the noise ( 19,8 dB(A) at 0,09 A) is at 0.20A and about as loud as the Deepcool 120mm fan from the Gammaxx 300 cooler i ordered with a 100W 7 band LED chip. i originally thought the deepcool fan at 0.1A was to loud and was fiddling with available power supplies to run it to cool a transformer. the noctua nf-p12 using it's power supply was much more quiet. now, the deepcool with the 0.1A and 5 nf-p12 fans on 1A (all 12V) are about equal in noise). if all data is true, 21dB(A) is the max of the deepcool, with 0.13A and 13.2V, (over the 0.10A, 12.0V) and the nf-p12 at 0.09A, 12V (i ran it at 0.10A, 12V) is 19,8 dB(A). the effect may have to do with,
http://noctua.at/main.php?show=nf_b9_blade_design
"Basically, an increase in static pressure usually brings about higher noise emissions. In the case of the NF-B9, this problem is dealt with by adding Vortex-Control Notches to the blades' trailing edges. Due to the two notches at the trailing edge, the flows along the suction and pressure side mix more smoothly. This allows for less turbulence and velocity loss, which leads to a significant reduction in noise emission as well as increased efficiency. In order to achieve the smoothest possible transition and maximum noise reduction, the Vortex-Control Notches are rounded in shape.
NF-B9 Blade Design
In addition to optimizing the joining of the flows at the trailing edge, the Vortex-Control Notches fulfil the task of psychoacoustic optimization: Due to the Vortex-Control Notches, trailing edge vortices are split up into several smaller vortices. Thus the noise is spread over a wider range of frequencies and therefore perceived as much less annoying.
"
the psycoacoustic optimization (2nd part), which seems make the lowered decibles be percieved as lower.
meaning that if i didn't plastic weld my fans into my rubbermaid contraption, i might have been able to use louder
[NF-F12 industrialPPC-2000 IP67 PWM (0.1A so 10, 2 stacked side by side array pushing {4} and 2 stacked side by side array pulling {4})( and 2 on the CPU cooler)
or
NF-A14 industrialPPC-2000 IP67 PWM (0.18A {push 2A through each} so 5, 2 side by side array pushing {2} and 2 side by side array pulling {2})(and 1 on the CPU cooler)]
fans for the same 12W. especially if the psycoacoustic effect is doing what i think with my nf-p12 fans at 0.2A each
the fans may be $20 each and i still go for them in the per suit of excellence. it made for a good experiment and a pc case would need less air flow, and a smaller filter than what i am aiming at (a closet like scruber/classic scrubber, done better, with pc fans and put in double stacked rubbemaids or orbis straight wall nesting crates (stack pack), focusing on pressure and noise rather than airflow (LEDs that are "full spectrum" and/or wavelength specific to reduce heat and keeping heatsinks built out of the case [heat pipe CPU coolers])

with 18gal rubbermaids instead for small closets with a 10gal head, LED COB chips and the cpu cooler built through so the radiator is in the head.

and blynx who gave me hope that micro can be done and supply a person.
(while other people yeilded better and give great ideas with pictures of their boxes, i mention blynx's posts there because of the apparent feasability of growing in enclosed spaces being shown scientifically, strain labeled, weekwise progressions using only dirt and no scrog fimming or training with only cfl lights, in 1sq foot space, showing that even without improvements it is possible AND what to expect. that is vital in a "guidemap" and it is still the most scientific breakdown i have seen yet (pot size was the variable with strains changing later) thanks)

''Operating Voltage 10.8～13.2VDC'' ''Rated Current 0.13±10%A(MAX)'' ''Noise 17.8~21dB(A)'' also after contacting Deepcool, i was told, "Its air pressure of the fan on DEEPCOOL GAMMAXX 300 is 2.03 mH₂O.
If still any further assistant is needed, please feel free to let us know."
(it seems there is an amp limit here. it seems to be different with Noctua. here is a transcript with them about that.
Q: ''Is it alright to run a non PWM NF-P12 at 0.1A? 0.15A? what is the
safe limit, even if the noise goes up?
(i know the specs say 0.09A so i just wan\'t to check about squeezing more from it
in my projects with the power supplies i have)''
A: ''there is a simple answer to it: Please just don't go over 13V, this is the limit.''
my fans are NF-P12 not NF-P12 PWM, which runs on 0.05A, 12V.
i haven't asked Noctua if PWM fans can run safe on higher currents(amps)
maybe 2 Noctua 140mm IP67 (NF-A14 industrialPPC-2000 IP67 PWM) can push/pull a good scrubber well in a pc case. maybe 0.4A, ~31,5 dB(A), ~4,18 mm H2O, 4.8W and quieter than the Silverstone FM-121, 3.26mmH2O fan with 39.5dBA at 2400rpm at the same 0.4A. double or less money and two 140mm (140mm squared area [may be minus the inner circles of the rotors) fans with more torque and lower vibration an noise (slightly; however especially if the psycoacoustic effect is doing what i think with my nf-p12 fans at 0.2A each), all water and dust proof, compared to a 120mm fan that only has an adjustable controll as a highground. i hope they make a 180mm
.RANDOM, I HOOKED UP A INDUSTRIAL 120mm 3000PPC (3 PHASE ) WITH TWO INDUSTRIAL 120mm 2000PPC and i the 3000PPC broke. i guess only the same fans can be hooked up on parallel? this may be like needing to use a current mirror in LEDs in parallel.

Hey i brought a pc grow case carbon filter needs upgrade as dosnt get rid off smells evectivly , my 1st grow was pinnaple exsprees and 2 fast 2 vast , during finnal weeks off flower when ever fans turned on my room stunk , im currently useing 1 grow bar led light and 4 cfl 2 off each spectrum 2700k an 3700k i believe . Weed was off a high quality for 1st grow , but im inrested in just useing x2 ufo Led (Same ones you use ) but not sure yet .
Im using pots atm but am also think about using a hydro system insted

Anybody have suggestions for a divider so I can turn my huge pc tower into veg/flower box?

maybe some sort of wood panel if you have tools
maybe plexiglass, it can be bonded with chloroform (glue acrylic)
LDPE and HDPE from rubbermaid containers are durable and and be cut, and joined by melting. but safety is important (like if you set it on fire to drip melt it). plastic welders could be used. i have gone through a few soldering irons working with rubbermaid containers. the aoyue one i broke by bending the heating element/tip, it was alright, but would smoke at the highest setting, and was noxious,
another was a cheap one that barely heated up and the electrical contacts broke off,
the other was a heat gun which i kept in the on position too long, which it said not to do on the instruction, which is different than ceramic heater ones which run a long time, also goop kept getting towards the contacts, these are good for strictly cutting, but a scissor could be used for most panels and flat bits.
the positives are that one big container, used right, would give you all the partitions you would need maybe. i don't know if you have enough airflow or pathways in and out for cooling your computer components though.
also there is a case called the
Thermaltake Core X9 Cube
which is probably good for maximizing space.
also, this $7 50W full spectrum 380 - 840nm COB LED might do well in there

(i don't know if putting the COB on the ceiling with heatsink adhesive and a heatsink with heatsink adhesive on the outside, on top would work ok, or if it would work but not be stealthy)

I'm also rebuilding a pc tower which I have used once with 2 test plants and got about 14gs out of. I want to build a good smell proof and stealth proof carbon filter for my next build. Any help would be nice.
I am currently doing a Pc grow. My case is DIY also and not as fantasy as his lol, but I did harvest 23g dry and cured from my first grow. My second grow is currently going on.
