A discovery engine for plant science — and an open platform for botanics, researchers, and R&D teams worldwide.
Truleaf.org started with a simple belief: growing plants shouldn't require expensive consultants or confusing spreadsheets. What began as a set of free tools for home gardeners has grown into something bigger — a discovery engine for plant science that serves botanics at every scale, researchers in academia, and R&D teams developing the next generation of agricultural inputs.
We combine agricultural research, soil science, mycology, and modern technology into an open platform built on peer-reviewed research, extension-service publications, and community validation. Whether you're growing herbs on a balcony or mapping whitespace for a biologicals pipeline, the same structured, citable science powers everything you see.
From a single raised bed to a multi-acre greenhouse, from a university lab to a biologicals R&D pipeline — Truleaf adapts to how you work with plants.
Balcony pots, raised beds, grow tents, backyard plots, and self-sufficient homesteads — anyone tending plants for the joy of it or for the table.
Market gardens, CSAs, family farms, fincas, agroforestry plots, and small greenhouses where every plant earns its keep.
Multi-acre greenhouses, vertical farms, hydroponic operations, plantations, orchards, and commercial mushroom labs — designed and deployed with a dedicated agronomist.
Science & Research
University researchers, PhD candidates, and post-docs studying plant nutrition, controlled-environment agriculture, and crop physiology — anyone who needs structured, citable plant data.
Biologicals companies, ag-input manufacturers, and research institutes developing biostimulants, biopesticides, and plant-health products — teams that need to map whitespace and track efficacy evidence.
Detailed profiles for 350+ species — from soil-grown vegetables and herbs to hydroponic crops, mushrooms, cannabis, flowers, and microgreens. Every profile includes nutrient requirements, growth stages, and environmental conditions across all growing methods.
Explore Plants
A science-backed mixing tool for hydroponic formulas and soil amendments alike. Calculate exact NPK ratios, micronutrients, and adjust for growth stages — whether you're mixing a reservoir or amending garden beds.
Open Calculator
Design and visualize your growing space in 3D — from a small grow tent to a full greenhouse or outdoor garden layout. Plan equipment placement, lighting, and airflow for any room, any environment.
Start Designing
Every plant profile and nutrient recommendation is grounded in agricultural research — spanning hydroponics, soil science, and mycology. We cite our sources and continuously update our database as new studies emerge.
Core tools are free forever. We believe every botanic — from hobbyist to commercial — and every researcher should have access to quality growing information, regardless of budget.
Botanics and researchers across all disciplines — hydroponic, soil, greenhouse, outdoor, lab — contribute recipes, tips, and feedback that make Truleaf.org better for everyone.
Truleaf is built as an open discovery layer for plant science. We structure and surface research so that growers can act on it and scientists can build on it — reducing the distance between a published paper and a growing decision.
The plant data in Truleaf.org is compiled from multiple authoritative sources across all growing disciplines:
Each plant profile undergoes validation to ensure accuracy. When scientific consensus varies, we provide ranges rather than single values, and note where conditions may affect results.
Have questions, feedback, or want to contribute? Whether you're a grower, a researcher, or an R&D team — we'd love to hear from you.
