16 Litre Tub We don’t like to waste anything, so our seconds and reused tubs have 25% off our RRP. The tub might be one we are reusing to reduce waste, or they may have old branding designs on them or the label may be a bit scratched. The contents however will always be our top quality soil conditioner. Help us to reduce waste and save yourself some money at the same time! Plant-based fertiliser and conditioner made from maize.
