1) I keep my relative intensity(par meter) right at/under 1000µmols. Plus or minus from there based on how the girls are doing. My average PPFD has not exceeded 1200µmols PPFD. But prefer the 800µmols then maximized the relative. Saturation levels are 1500µmols+.
2) Not more accurate as a thermocouple instrument...but more accurate/secure as a procedure/process/mounting. You can solder it to the Tsp point. (Tsp=Temp solder point), not rely in kapton tape or use adhesive with poor thermal properties, and/or getting some in between the couple and Tsp point. And that is how cree recommends doing it with the CX lines. K's are fine...just pushing your buttons... but I do really use a T-type now.

Gigahertz-Optik MSC-15- I have emailed them, but never got an answer on anything. I couldn't find a price either. If anyone has time to get ahold of them, please post info.

@nevergoodenuf WHEN IS IT GOING TO BE GOOD ENUF!! lol. thats a badass instrument , 360-830nm range..... !! must be expensive.

@Greengenes707 thanks for answering those questions. here is what I have. Ill be using the meter on the right side of the picture. and eventually getting an arduino based data logger up and running with temps referenced to a RTC real time clock. and collecting all sorts of data. (probably more than I know how to decipher, lol).

looks like my thermo tips can be soldered right on the COB?

@VegasWinner they look big and power hungry, but compared to HID lighting. theres only 1800w worth on that board. and only 1200w is being utilized right now.

@Scotch089 can you elaborate on bohhhhhdiiiii?

@The Green Griffin thanks for the positive vibes man.
-the pairs were originally configured that way from my original setup (700ma over a 4x8 . I kept the pairs because it should be acceptable spacing once I install 2 more bars, and I figure the light mover will smooth out my uneven umol readings across the X axis. but I am going for perfect even photon blanket here, so adjustments may need to be made.
-my man at my local hydroshop hooked me up with that C.A.P. controller for $100 used. I figured its worth that alone for the fuzzy logic CO2 controller. Would I buy one new for 6-700bucks, hell to tha no. its old tech and there are a lot of annoying things about it. but it is functional and the internal components like the relays and connections are all analog and very solid.
-sleep is for the weak.

@Michael Huntherz thanks brother, but please explain your new avatar to me. lol

@thetr33man Im glad you mention that (and picked up on the 100-150 umol drop). Not having the grow area enclosed in reflective material is clearly a dramatic drop off. GG and others have preached this for years. But seeing it here reinforces it further. Something will need to be done about this, or ounces of product will disappear into thin air.

@Greengenes707 I like the new kicks analogy. I was thinking new car that needs to get scratched or keyed, lol. So now you are telling me my K-type sensors arent good enough! when does the spending stop! I have this awesome setup and I'm eating frozen pizzas and PBJs for dinner already! lol
I have some questions for you.

-At what density to you start thinking about carbon (CO2) as a limiting factor for photosynthesis?
-is a T-type thermocouple more precise? I thought it just had a wider range.
-got any photos or links to your IDEAL mod, i want to make sure I am measuring from the right spot. (for the video).


For anyone else who reads this and has seen my videos. You guys are all very positive and constructive with me, and I appreciate it. I realize that my genetics are far from the dankest available. Early on, before youtube, I was so focused on yield and GPW. Now, I realize as most growers and consumers of herb, that quantity really doesnt mean shit when the genetics are average.
I like my Tangie because of the terp profile and the taste, even though bag appeal is not great, and the plant is not the most photogenic, lol. (but ill keep growing it, b/c i like it)
-alien blues has been retired due to dismal yields and no colas, bad pheno i guess.
-I feel like my only dank strain is the Exotic Genetics: cherry cream pie. featured in my "night nugs video" (although I have seeds for their Gorilla grip and Pink v2).

any comments on the quality of my genetics are welcome, my feelings won't be hurt. to refresh your memory , check this out. its end of wk6 or 7, i forget. but at 1:16 is the CCP. its pretty much what I am moving towards growing, until I get better.... #oceangrown

Get some of that bohhhhhdiiiii

in coming data: PIN vs FIN heatsinks pretty compelling stuff me thinks.
pins whether passive or active cooled win hands down.

In ad hoc testing I did recently I found the pins to allow better conduction of the heat from the base plate to the tip of the pin with a smaller amount of metal compared to fins. thin fins better dispersion, but lower conduction. thick fins for better conduction use a lot of metal.

Also found that air flow with sparse pins has lower resistance than fins and staggering the pins causes turbulence that increases air contact giving a heat dispersion better than fins.
