you should find bulbs that say it on them the last thing you want to do is buy a bunch of them and have them being the wrong temp I'm pretty sure that if they don't say it on them it's going to be hard to find out idk I'm new to this to I'm just think it make logical sence in my mind sorry I wasn't much help homie
your colors are normaly marked with a K like 2700K or 6500K I know personaly my XP is that you need to read the small print on the back of the box or sometimes its on the bulb itself.
You want 2700-3000k for Flower and 5500k-6500k for Veg. These are commenly marker as Sun or Warm for 2700k-3000K were as the 5500-6500k are marked as Cool or Cooler.
I can not stress this enough for veg anything below a 5000k is worthless and for flower anything above 3500k is worthless for growth. Also you want to assure your looking at true watts with CLF they are graded on = to normaly bulbs. So you may see a CFL that says its = 100 watts but infact its likely only 47 watt.
oh yeah lad i wouldnt buy if i didnt know fully sure what they were, yeah as far as i can remember it didnt say the temp in Ks or in warm n cool, ill have to go back to shop and read some more
If your at the store and don't see color temp pull out your smart phone scan the bar code you'll get a description of the bulb including color temp. Go Sharks!!!
bulb manufacturers almost always have any info you could want online along with resellers such as your local supermarket, just look up the bulbs at the store (online if possible) and cross reference. at least that way you usually find what will work for you if not what was in the store.
