Semi-hydroponics aka ‘semi-hydro’ or hydroculture, is a fuss-free gardening method using inorganic materials as its medium instead of bark, peat /sphagnum moss or soil. LECA / Clay aggregate is usually use as a medium. This is because LECA / Clay aggregate are light, absorbent, long-lasting, strong and porous. Semi-hydro is especially used for houseplants due to its convenience. With hydroculture, you will have less bugs and do not have to worry when about under or overwatering your plants.
