Guy 27 Posted May 31, 2017 Report Share Posted May 31, 2017 (edited) Plans for the new home for my CPs are moving on. It seems sensible to have a layer of something under the peat and perlite mix to allow any excess water to be drained off through the drain tap I'll be fitting. Gravel of about one inch diameter is the obvious answer, but will it introduce unwanted minerals into the soil? Guy Edited May 31, 2017 by Guy Quote Link to post Share on other sites
billynomates666 76 Posted May 31, 2017 Report Share Posted May 31, 2017 Depends on the gravel, you need something inert, you obviously don't want anything alkaline, nor any gravel that will break down in acidic conditins. Often gravel for fish aquariums is OK but is generally smaller than the size you need. Granite chippings may fit the bill. Cheers Steve Quote Link to post Share on other sites
Guy 27 Posted June 1, 2017 Author Report Share Posted June 1, 2017 How about these lava stones? Hope they'll be OK, I've just ordered a bag! Guy Quote Link to post Share on other sites
