Stop guessing your potting mix ratios. PlantMix builds custom soilless blends for your houseplants based on plant type, light, watering habits, and pot — then explains why.
Whether you're repotting a Monstera, a cactus, or a carnivorous plant, PlantMix recommends ingredient percentages you can actually measure and mix at home.
HOW IT WORKS
1. Choose your plant type (Monstera, Philodendron, Alocasia, Cactus, Succulent, Orchid, Fern, Calathea, Anthurium, Carnivorous, and more)
2. Set light level and watering habit
3. Enter pot size and material
4. Pick ingredients you have on hand — or auto-select the optimal set
5. Get your recipe by volume %, batch size in liters, and a plain-English explanation
BUILT FOR SUBSTRATE SCIENCE
• Porosity-based mix engine tuned to real horticultural material properties
• See water holding capacity (WHC), air-filled porosity (AFP), pH, and CEC for your blend
• Ingredient reference library with substitutes (perlite ↔ pumice, bark ↔ coir, and more)
• Warnings for tricky cases like carnivorous plants and poor drainage
SAVE & REFINE YOUR MIXES
• Save mixes locally on your device
• Version history when you repot or tweak a recipe
• Quick fork presets: too dry, too wet, or more drainage
WORKS OFFLINE
No account required. Your saved mixes stay on your phone. Compose and reference ingredients without a connection.
NOT A WATERING REMINDER APP
PlantMix focuses on what goes in the pot — the right structure for drainage, aeration, and moisture retention for how you actually grow.
