Ordering my medium and nutes online?

I'm considering ordering a 50L bag of Canna Coco and Cana A&B nutes from this website: http://www.hydroasis.com/ is this kosher?

Thanks,
Sleepless.

I order all of my nutes and grow medium online.I have never ordered from that company,so i do not know how their service is.I have never had a problem ordering online.Most of my orders are made on e-bay.OPH
