Turn your thermometer readings into a climate strategy.

Log temperature and humidity readings manually — no special sensors required. GrowScope calculates VPD from your numbers and derives a CO₂ target from the plant's stage and PPFD, using pure deterministic math. No AI credits are spent on climate calculations.

The problem

A thermometer tells you the temperature. A hygrometer tells you the humidity. Neither tells you the VPD — the single number that determines whether your plant can transpire properly. And CO₂ management is even harder: the target changes with light intensity and growth stage, but most growers either ignore it or run enrichment blindly.

Why it's hard to solve alone

VPD outside the right range directly limits photosynthesis regardless of light, nutrients, or genetics. CO₂ at the wrong level wastes money (if you're enriching) or caps yield (if you have sealed-room conditions that deplete ambient CO₂). Both are hard to calculate correctly by hand across changing conditions.

How GrowScope helps

Enter your temperature and humidity readings, and GrowScope computes VPD immediately. A separate deterministic CO₂ model — no AI, pure math — evaluates your reading against the target for the plant's current stage and PPFD, producing a verdict and any relevant warnings.

How it works

Manually enter temperature and humidity readings — the product does not include automatic sensors as a standard feature.
VPD is calculated from your entered values and fed into AI context for other features like watering and feeding recommendations.
A deterministic CO₂ model compares your reading against stage-appropriate targets derived from plant stage and PPFD — no AI credits spent.
The model produces a verdict for each CO₂ reading (in range, low, high) and generates warnings when values drift outside target.

In the app

GrowScope daily check-in — empty temperature and humidity fields — The only input GrowScope needs: today's temperature and humidity, typed in by hand from any thermometer or hygrometer — no sensor hardware required.

GrowScope VPD result — 1.43 kPa above target with a correction tip — Those two numbers become VPD instantly — 1.43 kPa against a 0.6–0.9 target for this plant's stage — flagged "above target" with a concrete fix (raise humidity to ~76%, or lower temperature slightly), not just a number.

What you get

You get climate insights — VPD and CO₂ targets — from readings you already take, without spending AI credits and without buying new hardware.

Frequently asked questions

Does GrowScope include automatic sensors or sensor integration?

No. Climate data is entered manually by the user — temperature, humidity, and other readings. There is no sensor hardware included or sold by GrowScope, and automatic sensor integration is not a standard product feature. A single pilot integration exists for one developer account only.

How is CO₂ guidance different from other climate features?

CO₂ targets are computed deterministically — no AI is involved. The model derives the target from the plant's growth stage and PPFD, compares it to your reading, and produces a verdict. This costs zero AI credits.

What does VPD calculation do for my other GrowScope features?

VPD is computed from your temperature and humidity readings and passed as context to AI features like Smart Watering, Feeding Tracking, and AI Plant Analysis — so those recommendations account for how well your plant can transpire right now.

Can I use data from my existing sensors?

Yes. You can enter readings from any thermometer, hygrometer, or CO₂ monitor you already own. GrowScope doesn't require specific hardware — it accepts whatever numbers you provide.
