KOOL BLOOM and RIPEN, the same thing?

I guess Ripen is made by the European division of General Hydroponics. I called my local shop and was told Kool Bloom is the same thing, but for USA.
Is it REALLY the same?
Should I buy liquid or powder?
Is there a different bloom enhancer that may be better?

Have you guys seen impressive results?

NO one can help me with this???

Bueller...Bueller...

As far as kool bloom the liquid and dry have a dif pk values. I use liquid from 12/12 switch through week 5. Then use dry 6-7 and straight water week 8. Im a noob but have gotten what I consider good results with it with gh's flora series and cal/mag. Just a hair under .5gpw every run so far in soil

I've also been hearing great stuff about Crystal Burst.
