This is interesting. Arent COBs all the rage these days partially because their intensity and penetrating power?

Like I said though, if youre running a dimmer and have it maxed you are likely running it at over the rated 100%. But ultimately I still believe its a non issue.

I just find this curious because it seems to fly in the face of all the research Ive been doing on VPD (vapor pressure deficit) .

You know, you come across as a pretty big dick in this thread, no offense. How are we supposed to have any idea how much electricity you need to live? Also, the power company will almost certainly not question you if you pay your bills. Considering how hard it seems for you to even...

No, money would be your limiting factor in that case. Power company will sell you as much power as you can buy. You should probably just stop using the term "limiting factor" because you have a different definition for it than anyone else. Also, have you ever grown before? It really sounds...

Do you know what your indoor humidity was from the time you had high temps to dropping them down?

So I hooked up my multimeter tonight and got some interesting results... The driver I got is the Meanwell HLG 320H C 1050A . Amps ranged from 410ma to 1210ma, with a voltage range of 288 to 301. Which gives me a range of roughly 118watts to 364watts. I didnt run the tests very long at all to...

Normal size screwdriver works just fine. Didnt cost me anything extra either, happened to have a screwdriver lying around lol. I cant dim below 50% though, so you got me there. Interesting note. Just did some testing with the multimeter and my A version dims from 37% to 114% of the rated...

A version gets me to 112% ;)

And another point, as long as you can keep Tc under 75c then ( which isnt hard to do at all ) it should still be under warranty if it dies on the short side of 20k hours being on a 12/12 cycle constantly. That or you squeeze that extra ~20% out of your light and weigh the costs of possibly...

This makes me wonder how they rate the non dimmable... just intentionally dialed back to 80% of what they are actually capable of perhaps. Also I wouldn't really worry as 20K hours is a little over 2 years at 24hrs a day.

cooler cobs put off more light. If I had to guess I'd think it would be TIM application differences perhaps.

They will work.

Your pump may struggle. you've got a lot of 90* turns and if it has to pump against gravity it may not work.

Your "limiting factors" are not really limiting factors or what normal people would call limiting factors. Limiting factors are among things that directly impact plant growth. or more specifically the things that are limiting the plant growth. things like light, nutrients aND atmospheric...

Well, looks like I definitely screwed up somewhere because I got my driver finally ( HLG 320 1050) and ran some tests with all 6 cobs hooked up and I came up with an efficiency of about 56% at 525ma. Regardless of errors, this is much more in line with what should be expected so Im happy my...

Thrips?

Heat pipe tech does not benefit us like it does PC builders. We dont have sensitive electronics that are packed into tight places like in a PC. I think youre missing the point that heat pipes do not dissipate heat, they still need to be attached to a heatsink. Then you have to ask yourself...

The lights put out ~7k btu... If they are active cool hoods much of that heat will be removed from the grow, so reducing the need for AC... I mean, is an AC unit really the only thing separating dense nugs from "fluffy garbage"?

Its reefer madness. Relative humidity is the relationship of absolute humidity and temperature. Hes failing to realize that you can change either variable, not just temperature. Likely too high when he wrote it... Perhaps a testament to his product. idk.
