Hey mate!

The Color Temperature (in Kelvins) are usually written on the label of the CFLs (bulb specification)... If its not there then i wouldn't buy it because you are not sure whether the color temp is good or not. If not, your plant will have a slow growth and could also appear yellowish.

Remember: you need to lower your light gradually as they become bigger and mnore resistant to heat. :thumbsup:

For example: you read on the label 5000K, it means the color temp of that/those bulb(s) are of 5000 Kelvins.

Vegetative phase (phase in which your plant grow) require Kelvin temperature between 5500K and 6500K.

Flowering phase require a bulb with a more red spectrum in the 2100K - 2500K (closest to 2100K if possible)

HPS (high pressure sodium) bulbs will do best for flowering! :thumbsup:

Hope it he
