About Truleaf.org
Free tools and science-backed guides for every grower — from first seed to full harvest, in any environment.
Free tools and science-backed guides for every grower — from first seed to full harvest, in any environment.
Truleaf was created to solve a simple problem: growing plants shouldn't require expensive consultants or confusing spreadsheets. Whether you're tending a backyard vegetable garden, managing a commercial greenhouse, cultivating mushrooms in a grow tent, or fine-tuning a hydroponic system — you deserve access to accurate, science-backed growing information.
We combine agricultural research, soil science, mycology, and modern technology to create tools that work for growers of all experience levels and in every environment — indoor, outdoor, and greenhouse. Our database is built on peer-reviewed research, and we continuously update our information as new studies are published.
Hydroponics, grow tents, indoor gardens
Controlled environments, year-round production
Garden beds, containers, traditional growing
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.

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 grower — from hobbyist to commercial — should have access to quality growing information, regardless of budget.
Growers across all disciplines — hydroponic, soil, greenhouse, outdoor — contribute recipes, tips, and feedback that make Truleaf better for everyone.
We promote efficient growing practices for every environment — reducing waste, optimizing water and nutrients, and helping you grow more with less, whether indoors or out.
The plant data in Truleaf 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.
