Our Data & Methodology

The plant data in Truleaf is compiled from multiple authoritative sources:

  • Agricultural Extension Services - University research and extension publications from institutions like UC Davis, Cornell, and Purdue.
  • Peer-Reviewed Research - Scientific papers on plant nutrition, hydroponics, and controlled environment agriculture.
  • Industry Standards - Guidelines from organizations like the Hydroponic Society of America and greenhouse industry associations.
  • Community Validation - Real-world testing and feedback from our community of growers.

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.

Open & Transparent

Truleaf believes in transparency. Our plant database methodology is documented, and we welcome contributions from the agricultural community. If you find an error or have updated research to share, we want to hear from you.
