The grow app that doesn’t ask who you are.
Stop guessing if your plant is okay.
GrowScope is a private grow diary and AI co-pilot that tells you exactly what your plant needs today — light, water, feeding, and when to harvest — without ever asking your name.
No email required · Free plan included · Runs right in your browser
You've checked four forum threads tonight and gotten four different answers. Is that a nutrient burn or just the light sitting too close? Is this normal for week six, or the exact invisible mistake that costs you the whole harvest? You're not looking for more opinions — you're looking for someone who actually knows this plant.
Every single day
Water, feed, or wait — stop guessing, start knowing.
Overwater and the roots rot. Overfeed and it burns. Underfeed and it stalls. GrowScope tells you which of the three today's plant actually needs, in exact amounts, built from its own recent readings — not a fixed calendar.
AI proposes the plan, but hard deterministic rules — safe dosing windows, mixing-incompatibility checks — have the final say, every time.
- AI-built nutrient calendar, tuned to this plant's strain, pot size, and substrate
- A single fertilizer cabinet — add what you own, GrowScope handles the math
- One decision card a day: water, feed, or wait, with the exact amount
How GrowScope fits together
One connected system, not another app to babysit.
Tell it about your plant once
Strain, pot size, box or balcony dimensions, your lights. It takes a couple of minutes, and it’s the only setup GrowScope ever asks for.
Get a plan built for that exact plant, every day
Nutrition calendar, watering, light and climate targets — recalculated for this plant’s age, strain, and equipment, not generic advice.
Check in with a photo when something looks off
AI reads it against that plant’s own history — its age, strain, and recent feeding — not a generic healthy/unhealthy guess.
Light and airflow, mapped — not guessed
You can't fix what you never measured.
A light that isn't positioned right wastes electricity, and dead zones you can't see cause stretch you can't explain. A physically-modeled 3D map of your actual equipment shows light distribution and airflow together — where it's strong, where it's stagnant, and exactly what to move.
Lambertian light distribution and wall-reflectivity modeling, calibrated against your own real PPFD readings — not a wattage lookup table.
- PPFD and DLI targets that adapt to the plant's current stage
- VPD calculated from your real temperature and humidity
- Airflow mapped for dead zones and direct-blast stress
A second pair of eyes
Four forum threads, four answers — none about your plant.
Something looks off and every thread contradicts the last. Upload up to four photos at once, and GrowScope reads them against that plant's strain, age, substrate, light, EC/pH, and recent feeding — not a generic photo classifier.
The trichome tracker reports the percentage of cloudy and amber trichomes — not a guess at a harvest date.
- Health index and week-over-week comparison
- Growth-stage and training guidance tuned to this plant
- Pest and mould screening based only on visible evidence
From seed to jar
Was this grow actually better than the last one?
Right now the answer lives in memory — and memory says everything worked. A dashboard stacks all your plants on one chart — growth, light, feeding — so you can see whether the new light or the new feed actually helped, not just guess.
Reminders follow the real 60/60 drying and curing target range, and every finished cycle becomes a data point for your next grow.
- Side-by-side growth dynamics for every plant
- Shareable AI-generated daily or whole-cycle summary cards
- Archive with g/W and g/m² results
GrowScope Lab
Your phone is the lab — no sensors to buy
Seven tools that turn your phone's camera and accelerometer into grow-room instruments. Honest relative readings against your own baseline, not fake precision.
And the rest of the toolkit
Everything else that's already handled.
EC/pH drift, flagged automatically
Drift is invisible until the leaves show it — and by then damage is done. Plain-math risk flags for drift, dilution, and drainage ratio catch it early, always on.
Growing outside? GrowScope adapts
Generic advice assumes a sealed tent. Balcony and terrace growers get advice for sun angle, wind, and discretion instead.
Your data, exportable or gone in one tap
Your grow history shouldn't be held hostage by one app. Export everything, including photos, or wipe your grow data whenever you want.
Every feature above is included in one plan. No tier maze.
Try it before you sign up
Free tools, same math as the app
Not simplified demos — the exact formulas GrowScope uses internally, running right here with no account needed.
VPD Calculator
Vapor pressure deficit from temperature and humidity, checked against your plant's stage.
DLI Calculator
Daily Light Integral from PPFD and photoperiod, checked against stage-specific PPFD targets.
Pot Size Calculator
Estimated height and diameter for a given pot volume — plan headroom before you plant.
Good grow or just what you're used to? You have no way to know.
Is your yield-per-watt actually good, or just good for you? You've never had anything real to compare against — only your own guess at “normal.” Now you can see your cycle length, development pace, and yield-per-watt against similar real grows.
Which raises the obvious question: how do we compare you to other growers without knowing who any of you are?
Your plants are yours. Your identity isn't required.
We don't ask for your email, phone, or name — the product was built without anywhere to put them.
Growscope
That’s the whole form — one field. No password either: nothing to leak in a breach, nothing reused from another site to break in with.
Your grow photos are analyzed by an AI provider to give you a diagnosis — that's the only reason they leave our server.
Your IP address is used for a few seconds to stop abuse, then it’s gone — never written to a log or database.
We never touch your device’s GPS. For outdoor features, you type in a location yourself.
Payment is crypto-only — no card, no billing address, no name on file.
Questions & answers
The essentials, without the fine print.
These answers reflect how GrowScope works today. If your question is specific to your setup, ask support — a real answer is better than a confident guess.
Signup requires only a username — no password, email address, phone number, real name, billing address, or card details. The rest is grow data you enter yourself. GrowScope uses no ad trackers and does not sell your data to advertisers or data brokers.
