The growth of dust grains by coagulation in disks around young stars is the first step towards planet formation. Grain properties in protoplanetary disks can be determined by the slope of the millimeter SED. Using this method, grain growth up to mm-sizes has been firmly established for ~30 disks in nearby star forming regions (SFRs). These initial results suggest that grains can grow very efficiently in the disk midplane and, contrary to model expectations, can survive there for a long time. To remove possible observational biases and to provide firm constraints to grain evolution in disks and the early phases of planet formation, we propose to extend our mm studies of grain growth in disks by conducting an ATCA survey in several nearby SFRs. Once completed, our survey will provide measurements of the mm-SED of over 90 systems. Here we aim to obtain 3mm data for 60 sources in three SFRs, thanks to the excellent sensitivity offered by CABB. All our targets have been detected at sub-mm wavelengths and we anticipate at least 5sigma detections. This approach will provide more accurate mm-spectral indices and allow a cloud-to-cloud comparison of environmental effects on grain growth.
