Turns out that GRO3 announcement was infusion related, not cultivation, so of no interest to us. However the announcement did state that they do have cultivation related deals/contracts progressing so Roto-Gro could be involved with some of those:
"The GRO3 Team has made significant strides toward penetrating the Cannabis Industry with the EcoPr03. Currently, GRO3 has 8 additional deals/contracts progressing behind the scenes across multiple sectors of the cannabis market including cultivation, extraction, and infusion. Further details about these upcoming deals can be expected over the coming weeks and as they continue to develop."
