Semi-hydroponics (passive hydroponics) replaces soil with an inorganic medium — clean, low-pest and good-looking, ideal for B2B office greening.
In this article
Two substrates
LECA (clay aggregate): airy and moisture-retaining, best for thick-rooted plants (Monstera, orchid); Lechuza Pon (mineral mix): suits fine-rooted plants (Alocasia, Pilea).
Two setups
Submerged (net pot in reservoir, wetter); wicking (pot suspended, cotton wick, drier and more forgiving).
Nutrient solution and upkeep
Use a complete hydroponic nutrient solution; flush regularly to prevent salt buildup, algae, lockout and root rot. Opaque containers reduce algae.
From soil
Choose healthy, resilient plants (Monstera, pothos, anthurium); expect a brief root-shock period.
Office appeal: Clear or frosted glass with LECA is tidy, no soil spill, no gnats — perfect for hygiene-conscious companies and clinics.
