MeGreenControlLog helps you run your greenhouse with clear, simple tools. Log daily work across these fields: date & time, crop, growth stage, temperature, humidity, CO₂, nutrients (EC/pH), water use, notes, and operator. Track lights in one place too: type (LED or graphene panel), intensity (µmol/m²/s), hours, spectrum, power use, and notes. Use quick helpers to balance temperature, humidity, and VPD so plants stay on track. Watch root zone pH drift and estimate dissolved oxygen in water before it slows growth. Check your carbon footprint and find easy ways to cut waste. Run a fast profit check on each crop or room. Convert angles between degrees and % slope in a tap for simple layout planning.
