Just to avoid yet more misinformation from those who "think" they know, Grosca is a wholesaler who's market primarily impacts California and Michigan. Based in ri, the owner was also listed to be the manager of the proposed Thomas Slater Compassion center. I don't run their gear but have visited quite a few rooms that they set up for patients (yup, bunch of assholes giving patients free grow rooms,....jerks) and their stuff seems to do just fine.
They just offered to outfit the "Jessica's Jungle" project. 8 x 1000's, scrubbers, fans, ducting, the works. All donated yesterday (it's on Facebook). Jessica has a brain tumor and a group of RI growers are all pitching in to grow a big batch for a stockpile of Phoenix Tears,....Grosca gave them all the gear
I see these guys in our community all the time, doing good things, felt they deserved defending.
