Disclosed is a substrate for artificial turf that includes a base pad with a channel that extends across an upper surface of the pad and a tube that lies within the channel. The base pad has a generally flat lower surface and a generally flat upper surface that is spaced apart and oppositely disposed from the lower surface. The channel has a sidewall and a bottom surface, the sidewall extending from the upper surface of the base pad to the bottom surface of the channel and the bottom surface being spaced apart from the lower surface of the base pad. The tube has a sidewall defining an inner diameter surface and an outer diameter surface, with at least one aperture through the sidewall adjoining the inner diameter surface and the outer diameter surface. The channel and the tube are operable for liquid to flow through. In some instances, a radiant heating wire can extend across the upper surface of the base pad.
