32w 2700k versus 23w 5000k for veg?
So I have a pile of bulbs to choose amongst for putting over my seedling (see sig link for pics of the little girl), and I'm trying to decide whether it's better to have more lumens or for those lumens to be in the vegging part of the spectrum.
I have four sockets for CFLs to put right over the seedling, which currently have the following bulbs:
1x42w 6500k (2800 lumens)
1x42w 2700k (2800 lumens)
2x32w 2700k (4400 lumens)
Total: 148w (10,000 lumens)
I'm definitely going to keep the two 42w bulbs, even though one of them is 2700k, but I'm trying to decide whether I should swap out the 32w 2700k bulbs for 23w 5000k ones. I don't have any higher wattage 5000k or 6500k bulbs, so that's not an option. If I do swap them, I'd be losing a total of 1200 lumens, but I'd be changing from 28% of my lumens coming from vegging spectrum to 68%.
So who thinks I should swap them out for the 5000k bulbs, and who thinks I should keep them as-is with the higher wattage 2700k ones?
P.S. I mistakenly bought these 5000k bulbs thinking they were 6500k since they said "Daylight," but it looks like 5000k is okay for vegging too, right?
5000k will work
buy u some of these and use all the bulbs u got
I'm already using those things:
I will be adding more bulbs as she gets bigger, but I just want to know which would be the best four (4) bulbs to use for the first couple weeks.
ok i looked at grow in signature

Is that a 5 gallon bucket you made the "reflector" out of? Pretty sure those let off some fumes or whatever when they get too warm, I'd be careful about that.
148W is plenty, your spectrum is fine just personally id add another 6500k and or 5000k to promote veg. theres pretty inexpensive bulbs on ebay some are like 6 bucks for a 20w 6500k, theres 6-8 dollar packs of 6500ks at walmart or if you really can't get one yes id personally say lower your watts but get that 5000k in there this is the time your supposed to have the blue spectrum you already have plenty of light for the flowering so at least you dont need to worry about that, hope i helped.
Yup, but it's a food grade brewing bucket rated to 190F. I don't imagine it releases any toxic fumes below the temperature it's rated for food. I definitely wouldn't use it for anything other than CFLs, but when I put my hand on the bucket it's definitely not 190F. But in any case I'll be switching to real reflectors once I have a couple larger plants, have no fear!

Right now it's 1x42w@6500k, 1x42w@2700k, and 1x23w@5000k. As soon as she gets a little bigger I'm planning to add a few more bulbs (maybe 2-3 weeks from now).

lots of people do
but a better reflector op would be buy a short piece of galv metal duct
and split in half then u got two reflectors
there is even a few diy threads in diy sub forum
I did line the inside of the bucket with reflecting tape since a lot of light was leaking through the plastic, but I'm probably just going to buy some real reflectors soon instead.
