Black dog led vs kind led

[mauricem00]

Do they get very hot though?

any light is going to produce heat even LEDs. LEDs provide a better spectrum than HPS but CMH produce the best spectrum for plant growth. closes to natural sunlight for a space that size you are going to need ventilation and possibly A/C.I live in the high desert where humidity is low and summer temperatures are high but an evaporation cooler lowers temperature and raises humidity. we all have different environments and different strains so you will need to experiment to find what works best for your environment and strain

that would actually be a great test, 300w cmh (350W at the wall) vs 275W of LED side by side in 3x3 spaces

both should be better than the HPS youre used to

GREAT info if that's closest thing I can get to the sun I need that... sun does amazing things

I just told OP to be careful WHO he takes his info from. and THEY changed it from LED vS LED to both of those suck, here is ours.

Oh where did I say here is ours? Show me where I stated anything but fact....... Furthermore I said anything over 2.0 umol/watt lots of companies doing that..... Personal attack any???? You are going back on ignore..... I'm not feeding the trolls any longer no hope for you bud. A pitty too. You are in the LED AND OTHER LIGHTING SECTION. IF YOU DON'T LIKE LED YOU ARE IN THE WRONG PLACE.

CRI isnt really as big of a deal for our application

CMH has 90+ CRI. HPS has CRI in the low 20s but still grows great bud

not dissing CMH but the CRI is just one of several attributes

it has more to do with the amount of blue,violet. and UV a light produces.plants have close to 400 different pigments. you can grow them just targeting 4 pigment (red/blue monos) but you get better quality and higher yield with true full spectrum light. CRI deals with human eye response so a RGB LED can produce a very high CRI but only drive a few plant pigments.look at the SPD for CMH bulbs and compare that to the SPD for sunlight and the absorption spectrum for cannabis plants.even with my T5s I use a mix of P@A, 6500k and UVA plus bulbs to get close to the absorption spectrum and see an increase in yield and potency over just 6500k bulbs.with LEDs you need 1700ppf to cause photo inhibition and other signs of light stress. with sunlight it only takes 700ppf. this is the bases for claims by black dog, platinum. and high end LED makers that plants only use 40% of the light produced by white LEDs .with so many contradictory claims being made the only way to know the truth is to do test grows.on youtube I have seen great grows with CFLs and these are the least efficient lights being used to grow plants.

been doing for a few years, sorry if you don't believe, but I grow trees.

You call plants done under ceiling less than 8 foot trees??? Haha.

Okay. Have fun with that.

I invite you to read the first post AGAIN, and maybe comprehend what the op wrote. Crybaby!!

Any input will help even if it's recommending other sorce of light

"danielson"?

You fucking retard. LMAO.

BTW - Did you know the Riviera was discontinued back in '93? fuckin idiot

you don't even know your own references fuckin idiot!!!

 

[Dr.Nick Riviera]

LOL

You spelled it "danielson", you fucking tool. Nice job, clown shoes.

 

[Johnny Lawrence]

LOL

Yeah, i guess that's one way to spell "fail".

So tell me again - what did this Danielson character do?

You are a liar where did I say here is ours? I actually mentioned HPS was better than both. ( personal attack much)?

I did and told him nothing but fact TROLL lmao

I invite you to read my post again as well.... Will you admit you jumped the gun? Nope..... Will you admit I stated nothing but fact? Nope not man enough to own up to your mistakes. SAD really.

I never said your name specifically, feel guilty much? Probably because I hit close to home. But yeah, you posted some info that the OP probably has no clue what it means.and while not actually saying your units name, your avatar is an AD. good job.
