HOUSEPLANT SEMI-HYDROPONICS

While we have a lot of experience in outdoor gardening and market farming, we also have knowledge of houseplants. It comes with the territory of being immersed in horticulture. Evidence is showing that semi-hydroponics results in increased growth and health of houseplants. Semi-hydroponics, semi-hydro for short, is the technique of growing plants in an inert medium like lightweight, expanded clay aggregate (LECA), perlite, pon, or pumice. These growing mediums don’t rot because they can’t decompose. They’re inorganic mediums made from rock. Most of these have microscopic pores that hold air.

Out of all of these mediums, we like pumice the most. Pumice seems to hold water better than the other mediums and it’s irregular size makes it act more like soil. It’s heavier than perlite, so it won’t float when you water it. It’s also readily available in our part of the US and it’s more of a renewable resource than the others.
