Grow it right the first time

Budometry is a complete home-grow school and gear shop: dial-in guides for every stage, an AI Plant Doctor that reads a photo of your plant, and the lights, fans, filters, and nutrients that actually move the needle.

Legal notice: We do not promote or encourage breaking the law. This site is for adults 21+ growing in states and jurisdictions that have legalized cannabis cultivation, and who are following all legal growing guidelines, plant count limits, and permit requirements that apply to them.

The six stages

Every grow follows the same arc. Know the targets for each stage and most problems never happen.

AI Plant Doctor

Snap a photo. Get a straight answer.

Upload a picture of your plant and our AI tells you what stage it's in, what's wrong with it, how close it is to harvest, and exactly what to do next — plus which gear fixes the problem.

  • • Nutrient deficiencies, light burn, heat stress, overwatering, pests, mold
  • • Harvest readiness from pistils and trichome guidance
  • • A prioritized next-steps list you can act on today

Sample readout

STAGE: Mid flower — dense bud sites, most pistils still white.
ISSUES:
- Slight nitrogen tail on lower fan leaves (normal this late)
- Canopy humidity looks high; leaves are praying but tacky
HARVEST READINESS: Roughly 2-3 weeks out. Check trichomes with a loupe.
NEXT STEPS:
- Drop RH to 45% with a dehumidifier
- Defoliate the lowest larf sites for airflow

Gear that earns its spot

Lights, timers, airflow, climate control, watering, media, nutrients, and genetics.
