Perlite Alternatives Rice hulls share similar physical properties with perlite and may be substituted for it in fresh or parboiled forms. Because parboiling rice subjects it to steam pressure, which kills all weed or rice seeds, it is preferred over fresh rice in potting mixes.Also Know, how do you use horticultural grit? Add approximately one handful of grit (40-50g) to each litre of compost and mix well. Many plants such as alpine and cacti do not like moisture. To aid drainage and to keep the foliage dry remove 1-2cm of compost from the pot and replace with Westland Potting Grit. Correspondingly, what is the difference between perlite and pumice? Perlite is lighter weight than pumice and lighter in color. It is pure white. In soil mixes, perlite tends to float to the top of the soil, spilling over the edge of a pot when watered. It usually costs less than pumice and is manufactured in different grades, weighing as little as 2 pounds per cubic foot.Which is best perlite or vermiculite?Perlite and vermiculite are both good at retaining water, but vermiculite acts more like a sponge, holding much more water than perlite and offering less aeration for the plant roots. Because it is porous it allows excess water to drain more readily than vermiculite and improves soil aeration.
