Abstract
A method of growing plants in a coherent growth substrate product can comprise: providing at least one coherent growth substrate product comprising man-made vitreous fibres (MMVF) bonded with a cured aqueous binder composition free of phenol and formaldehyde; positioning one or more seeds, seedlings, cuttings or plants in contact with the growth substrate product; and irrigating the growth substrate product. The aqueous binder composition prior to curing can comprise; a component (i) in form of one or more lignosulfonate lignins having a carboxylic acid group content of 0.03 to 1.4 mmol/g, based on the dry weight of the lignosulfonate lignins; and a component (ii) in form of one or more cross-linkers.
