This study aims determine best type for orchids. research was conducted using experimental method preparation a Factorial Completely Randomized Block Design. The first factor medium, namely coconut husk, moss husk + moss, second fertilizer, without foliar liquid organic fertilizer. From two treatment factors, 9 combinations were obtained. Each repeated 3 times each replication consisted samples. results showed that there mutual influence between Meanwhile, compared fertilization, increase growth orchids during acclimatization.
