Sometimes the packets won't say - The makers don't have to. In my experience of generic or branded CFL's (Sold for general house lighting) they seem to be the 2700k type.

I have found this picture, Kelvin colour I was hoping to find a 'real' picture of various kelvin rated CFL's but i could only find this CG picture.

It gives you the jist of it anyway. The lower the Kelvin rating the yellower it appears, the higher the Kelvin the "whiter/bluer" they look. so you should be able to estimate your bulbs if it doesn't say. You want the white looking ones for veg.

I dont think you need the rooting hormones, they are used for cuttings (clones). but useful if you are going to clone.

23watt bulbs are fine, the more you have the merrier the plants. Its just the kelvins you need to get right
