Soft, daylight, bright white?

[adrianvasquez1985]

i went to the store n i bought 2 of this kind
Walmart.com - Always Low Prices! - GE CFL Light Bulb: 42 Watt (150W Equiv) 2-Pk 2050 lumens

and 2 of

Walmart.com - Always Low Prices! - GE CFL Daylight Light Bulb: 26 Watt (100W Equiv), 6-Pk 1600 lumens(im not sure) should i return one of the packs and get all daylight or the lumens r more important even if its not 6500k? cuz i think the 2050 lumens r 2700 or 3500

For vegging you should be using ALL 'daylight' or 'cool white': 6500k

Using a warm white (2700k) will induce stretching and most of it's wavelength wont be used.

For flowering you want mostly red light with a few blue here and there. Say a 4:1 ratio

what cfl would have the red spect to it??

 

[daisy2687]

Red bulbs are labled as 'warm white'

If you look closely on the packaging you can find their Kelvin rating. For red bulbs the rating is 2700K. For blue bulbs it is 6500K (labled as 'cool white' or 'daylight')

im just gona get 6500k cuz i dont need a big plant im gona try to keep her low about 2ft.

 

[adrianvasquez1985]

will i need a diferent spectruc lights when i switch to flowering? like the 2700k or the 3500k?

 

[daisy2687]

Yes, when you flower you change all your bulbs from blue to red. SO for flowering you want all 2700k (maybe a few blue ones)

For vegetation don't just get all bright white bulbs. Sometimes mixing up the spectrum will help this particular cycle. Try doing a 10 to 3 ratio?

I'm currently using a 50-50 approach. 4 softs and 4 daylights.

As for flowering, yes, use all red spectrumed bulbs or soft whites.

Although i'm using a 400w HPS for flowering, I'm using CFL's for my veg cycle and i was looking for the 42w 6500k's. i checked all the walmarts in my area and they're all out of the 42w daylights (6500k). On a whim, i was bought six 30w 5000k cfl's somewhere else for a decent price, but i know 6500k is the best.
I'm really shooting for small, tight plants.
Would i be ok if i mixed in some 42w 6500k's with these 5000k's or should i scrap the 5000k's all together and just go get 6500k's?
thanks

Here is a list of spectrums for cfl's.

1. 6500K (daylight)
2. 4100K (coolwhite)
3. 3300K (softwhite)
4. 2700K (warmwhite)

For best results use a ratio 3:1 during all stages. Using the 6500K and the 4100K work best during your veg, and the 2700K and the 4100K during flowering. Just be sure to concentrate on the blue end during seedling and veg cycles, and the red during flowering.

ok thanks guys... im gona add 1 more bulb 30 watts cfl 2700k(125w)

Walmart.com - Always Low Prices! - GE CFL Light Bulb: 42 Watt (150W Equiv) 2-Pk

I saw these too and was wondering what kind of light warm or cool they dont say anything I dont want soft i need cool or warm no specs,

But i saw this for Walmart.com : Great Value CFL Light Bulb: 23 Watt (100W Equiv), 4-Pk : Decor alittle over $7 you can get more watt per $ but I cant find out if it is warm or cool.

I found that I can hook these lights up in series and make my own setup. otherwise I need to find some sockets that I can hard wire together any advice on how I should wire them up, because they are 23W i will get 12 so 276watt I hope i can get them in warm white, if not I will get this item because I will know what i am getting,, Compact Fluorescent Plant Grow Lights & Fixtures by Hydrofarm at Home Harvest Garden Supply

Will 4 6700K and 8 2700K 23-26 watt work for flowering and veg?? I would like to just keep what I have and not have to buy more bulbs. Right now I am only using 4 6700 and 2 2700 for veg. Next for flowering I want to still use the 4 6700 lights and add 6 more 2700Ks for flowering.. So how does this sound?

 

[goodgreen]

Ok so here is what I am doing, I just made a simple 4 6700 light fixure in another closet and will put one monther under it 24/7 for my clone, I will take cuttings and flower them with my 12 light soft and cool fixure i made, I will take some pics soon.

 

[adrianvasquez1985]

im planning on buying some seeds then im gona choose a mother n im gona start clonning cuz i wnt to harvest once a month....

 

[Joker52]

i've got a closet and use blue for veg, bright for flower.

 

[projump]

I really beleve it is ok to use a few cools when you flower. I am using cool mixed with the warms because I want to raise and flower clones and I need the cools to help the veg cycle out. I dont want to change bulbs each time.
