Rockwool vs. Cocopeat--A Head-to-Head Media Event!by Bob Johnson

Only a fraction of the carnations remain that once filled the Green Valley Floral greenhouse complex on Old Stage Road outside of Salinas when it opened in 1985. The market for U.S.-grown carnations has been so reduced by low-cost imports from the Andes that even the remaining acre of Green Valley’s carnations will soon be phased out.

As the carnation market soured under the pressure from low-cost imports from Colombia, red roses were planted. But soon the rose trade followed the carnations south. So Green Valley sought refuge in more than 60 varieties of tea, sweetheart, and spray roses of every color. Their highest quality long-stemmed roses are grown hydroponically in coconut fiber (sometimes called coir or cocopeat).
