why 5000k is better.

SOMEBEECH said:

Hey Poly i was gifted a 1k MH and really dont need it,was thinking of a conversion bulb to HPS.

You have any thoughts? Also,What do think about adding some Cfls blue spectrum to a 400wHps in a small space,like a 3x4 with Mylar?Thanks in advance.

3:1 red to blue Beech! Read it lot of place! The plant's should like it better than just having one or the other! I'm using some blues in there w/ my red!

polyarcturus said:

actually 5000k and 3500k for flowering would be most efficient. but yes what you are saying is correct.(unless your using specialty red enhanced bulbs such as redsun, colormax ect.)

I read a few places too that 35k is the most ineffective CFL that you can use, but I still added a couple in just to mix my spectrum!
I think we should hold this thought and bring some fourth some more documentation before we go to far!
What you got for us Poly?

I've read good and bad about the 35k CFL

Yeah I lol'd at my own thing. It's just the 23w coming into play that made me bust up laughing. I dunno why? I find it funny!

Yeah...I just don't know why you think it's so funny because I happen to mention my bulbs were 23W, I was asking for advice concerning 5000k, which was the subject of the thread.....my questions were serious but I guess it's just fun to belittle those who aren't running 150w CFL's.

Thanks Poly for answering my rookie questions with respect

Not even. It's all love bro. You just gotta ask the right question to get the answers you want....
It shows that you've applied yourself, which would go a long way with me(personally)....
I(personally)don't answer question that I think are "not good" or could be easily answered via google ya know?
But I'd easily put some effort in to help someone whose looking for some good info, but not quite there yet.

I'm still a rookie bro...But I know a hell of a lot bcuz I wanna know what I'm doin' here. Therefore I'm always looking to learn

Sorry bro but you missed my point...my concern it was not about "asking the right question", as Poly did answer my questions

my last post was asking why those think 23w bulbs are so funny....I'm sorry but that's what I have....maybe one day I'll get larger lights but for now this is what I have to work with...

sorry for being defensive but it appears I'm being ridiculed becasue I'm only using mere 23w bulbs....so if I had said my bulbs were 150W, would that have made my questions about 5000k more legit?

Sorry you took it that way,It was tht kron was tottaly off the subject.
Hey we all started small,me also I did the cfls and still usem.

I apologize if I offended you.

conversion bulbs work although a 1000w conversion HPS may be impossible to find, i would stick with the MH or go play with one of these
http://www.ecat.lighting.philips.com/l/lamps/high-intensity-discharge-lamps/ceramic-metal-halide/energy-advantage-cdm-lamps-with-allstart-technology/928601172801_na/

just remember something like that is a vertical bulb, so bare bulb, parabolic or something like the OG or luxor reflectors would be best for it.

adding CFLs to HPS ezpeciall something like a 400w is realistic, because with the 400w the intensity is not too much more the make the placement of CFLs in efficient, so i say do it! hell if i where you i would only add 26w 10.0 reptile uvb bulbs(basically a 6500k bulb with some UVB output). like 4 or 5 for that space.

the main thing about the 3500k is that its only slightly better, maybe 10% better than a 2700k. is it worth the improvement ist up to you, the charts a page back are accurate, and shows that the 3500k has a wider spectrum in the red than 3000k.

Thts what i wanted to know if adding Cfls to Hid would do anygood.
I dont see it really helping with say 600-1000hid,Correct me if im wrong....

chill man, that where cracking jokes at me, i dont use CFL and flouro all like that , me, kron, and somebeech all use err, bigger toys. but i always appreciate th backup

and no problem man, i always try to help the best i can

thats good to know cause i just bought a slew of phillips 500k t5 lamps this morning for 7.50 a piece. of course before I read the thread, I was going to do one 6500k, 5000k,6500k, 5000k in my 4ft 4bulb fixtures. thanks for the research!

your not wrong, unless well your talking about some T5 or PLL lights which could at least do some damage at those types of distances, but really for the wattage heat they produce added another HID might just be simpler.

Mine was for Kron,Not you he was way off the Subject!!
Also i have a chit load of 23watters,And i think they vegg better
then my T5HO.

But it was free also came from Ups with no addy from where it came from,I kept it for months before I even opened it.

this is phillips3500k T5ho chart

couldnt find 5000k again it was same chart on a website with the 2 bulbs. fuckers.

they should veg better but only up to a certain distance, and the reason for this is, because there are more angles of light hitting the plant surface under cfls. in terms of intensity being very close to a cfl will provide the most light in a small area. perfect for seedlings, and clones and even flowering small plants.

i would also like to point out fter some respeach and what i have seen being alluded to, is thats 2700k,2800k and 2900k are all the same phosphor mix as 3000k, but this is because in any brand you look at (besides grow lights) only CFLs have those kelvin values, because thier bulb shape and tube diameter effects the spectrum slightly.

this is why slick marketing guy use the 2800k rating on some linear bulbs without offering a spectrum graph(you will be hard pressed to find a 2700k graph) because they know the mix is the same as the CFL mix, but produces a slightly different light.

if anybody can found some solid evidence to back up what ti say or a 2700k linear bulb graph,that isnt a 3000k mislabeled that would be great. of you can prove me wrong that would also be great, perhaps the mix is different but from what i am reading it is not, just tube shape and size.

Poly - it appears your Philips 3500k and 5000k charts are the same. I just got some Philips 5000k HOT5s the other day and would love to see the chart as it compares to the 5000k Flora Sun.

Thank you for your information in this thread, it's very helpful.

So did you guys ever figure out which 23w bulb was most efficient. Lemme know when you guys have this chat about some 1000w gear. I'll be interested then.

Hope that's on topic enough for you.

I thought you can have a MH conversion bulb running off a HPS ballast, but not a HPS bulb running off a MH ballast - there is no ignitor :/
