About
About HydroGrowLab
Free tools and guides for hydroponic growers — calculators first, then crop and system notes you can actually use.
Why this site exists
Hydroponics rewards precision. Wrong pH, the wrong PPM scale, or a vague “feed until it looks right” recipe wastes weeks. HydroGrowLab keeps the calculators and crop guides free so you can act on numbers instead of guessing.
What's here
Nutrient and environment calculators, system guides (DWC, NFT, Kratky), plant pages, and editorial gear reviews. No account required.
Editorial policy
Reviews describe what we look for and how we would use the gear. We do not accept payment for rankings. Calculators and guides are free — useful tools first, ads later only if they do not get in the way.
