full spectrum 5000k cfl instead of 6500k for veg whats your opinion?

Thanks pedro I learn something every time you post. The system hasn't let me rep you for a while. Yet still...here we are. A bunch of cfl growers with no SPDs.

• Is anyone the wiser from this thread, in real terms of which specific CFL to use?
• Who is not planning on using a 5000k or 6500k for good veg growth, after discovering these revelations?

Seems to me we are both right, really. I still don't know my bulbs' spectral output so this hasn't really changed anything for me. We can talk about SPDs all day but yeh, not gonna help most consumer CFL guys. Thanks for explaining your stance so well. If I do find a bulb that doesn't perform as expected, well I know probably why.

I'm going to stick to the old fashioned method of analysing bulbs - by growing a plant under them and observing. Peace.

Edit: I think if there are bulbs that don't perform as expected, we should have some kind of sticky or database so we know which bulbs not to buy. I can't contribute, obviously.

If you get a hard copy of the commercial (not retail) catalogue from companies like Sylvania, Philips etc they have spectrum charts for their CFLs and 2G11 (pll tubes) in them, not sure about online though.

Hey Canna, yeah I looked for the bunnings bulbs, the main ones most aussies use, and they don't have one. The main brand other than that is the Osram Duluxstar mini twist 23w'ers - they have a pdf but they break it into 3 seperate charts, one for red, blue, green, or something - I couldn't work it out. No problem finding them for Osram pl-ls though.

I use a 125w 6500 cfl...it's huge and it rocks. It outpreforms my old 5000 by just a little.

You guys have some good cfl options in your stores!
It would be fun to see what people can find of strange bulbs around the world.
DK is different from what I see here when it comes to cfl's.
Where I live it is very hard to find cfl's bulbs above 30W, except for the big 100w+ e40's from the growshops. It's easy to find all kinds of tubes though, and we have a few mostly internet based shops who sells pll's.

I love the ufo bulbs, use them for a lot of plants during the dark winther.

Everything is expencive here. An osram pl-l 827 55W costs 25$!, a 20W e27 can easily cost 20$ It's a bit cheaper to buy our stuff in germany.
I bought this work lamp for 35$ though, two 36W pl-l's, it is to become vegging light. Didn't like the 4100K's, that came with the lamp, and they will be replaced with tritons (My favorite bulb of all time ).

How!

How!

I've used 5000k a lot because they only sell the big watters (well, 48w lol) in that temp here, in the veg range. It works fine. Definitely no need to buy a new bulb imo.

Hey buddy i got some 250w ers i wanna hang. ive only got the fitting e40 hanger. how did you get them to sit like that buddy?

Hi Scroger, those are just those mechanic's hendheld lights for looking under cars and such. I'm not sure of the E-size but they're standard household size. They have a clip on them, as well as a reflector but I cut the reflector off and make my own, or so I can hang them vertically. They clipped to a bit of scrog screen up near the roof.
