Soft White

[noone4u]

I have a question and im hoping someone can help me out

Today I bought some "soft white" CFL for the mother cab

They put off a yellow light?? wtf

Im used to the light being white what gives?

Should I get different ones or will these be ok?

If they are actually warm I dont want use them because of stretching I guess

soft white is more for flowering
day lite is more for veg.

I thought it was soft white for veg and warm white for flower ??

check the manufacturers info on what light spectrum its emitting. it will be in kelvin something like 4500k. warm white is 2700k. day lite is 6500k. if you combine some daylight and soft white your plants will grow fine. but plain daylight works wonders too.

ok well shit lol

what is a warm white used for? am i crazy is there no such thing as warm white? or is warm white just refereed to more as daylight??

warm white is yellow
cool white is blueish/white

they just typically dont say that on CFL packaging, but that's how standard floro tubes are marketed.

for vegging mothers you want cool white, or daytime, something with a higher color temperature, like 6500k.

From wikipedia:

Color temperature is a quantitative measure. The higher the number in kelvins, the 'cooler', i.e., bluer, the shade. Color names associated with a particular color temperature are not standardized for modern CFLs and other triphosphor lamps like they were for the older-style halophosphate fluorescent lamps. Variations and inconsistencies exist among manufacturers. For example, Sylvania's Daylight CFLs have a color temperature of 3500 K, while most other lamps with a 'daylight' label have color temperatures of at least 5000 K. Some vendors do not include the kelvin value on the package, but this is beginning to change now that the Energy Star criteria for CFLs is expected to require such labeling in its 4.0 revision.

Some manufacturers now label their CFLs with a 3 digit code to specify the color rendering index (CRI) and color temperature of the lamp. The first digit represents the CRI measured in tens of percent, while the second two digits represent the color temperature measured in hundreds of kelvins. For example, a CFL with a CRI of 83 and a color temperature of 2700 K would be given a code of 827.
