Anyone have compacted, decomposed granite floors in your g.h.? If so, would you do it over again?
I use DG for walkways and patio floors but all outdoors never in a greenhouse or indoor use. From what I have seen is can become slippery when overly wet and also will turn green with alge, DG drains well if the base material is done correctly prior to installing DG, Also DG must be compacted very well to avoid sinks in the final product.
In my greenhouse I used a weed block material then a 2 ince base of peat moss and charcoal(I thought that the wet peat would help to addd RH, don't know if it worked or not?) then covered with 3/4 chunk gravel 4 inces thicks, then over that I used pea gravel for final level.
