They grow their phals hot, above 26-27 C, under ideal conditions for vegitative growth for a long period of time. About 90 days before they need flowering phals to sell they lower the temperature to below 16-18 C for flower spike initiation and hold the temperature low during spike developement.
What most people do wrong is that the plants get to little vegitative growth under non ideal condition. The plant accumilate to little energy and as the spike is initiated and grown under non ideal condition the result is most often less good compared to what the professionals produce.
Another issue is that when you buy a plant it has been pushed to it´s limit and is often really stressed. You can not expect a really good flower display the first rebloom as the plant is in recovery phase.
