Resumo: Hydrangeas have been a very important greenhouse crop well known for their large colorful inflorescences. Once such plant, ‘Avantgarde’ hydrangea, is a hybrid between some Hydrangea macrophylla cultivars that don’t need cold to bloom. Therefore it is possible to make the entire production in 22 to 26 weeks by using the appropriate photoperiod and light. For the present study three trials were design to adapt ‘Avantgarde’ culture conditions to the usual production of better known hydrangeas. Regarding density, best results were obtained by using density 3, which means half of the density conventionally used. Cold was responsible for the delay of flower developmental stages of plants in trays. Some interaction effects were detected between different times of cold storage, different concentrations and frequency of growth regulator applied showing a trend of associating long cold storages to delayed flower stages. Larger growth regulator applications are related to smaller plants. Treatment frequencies have more influence on the final plant height than the applied concentrations
