Complaints
If you have a complaint about a growing media product, please address these with the manufacturer directly. Unfortunately we cannot resolve complaints about products or take these up with manufacturers on your behalf. If you have a complaint about the association, please follow our complaints procedure so we can deal with this as quickly as possible. As a sub-group of the HTA your complaint will be handled the HTA complaints process.
