Build a nutrition plan for the whole cycle, not one day at a time.
GrowScope builds a full-cycle feeding calendar deterministically — zero AI credits — from your strain, pot size, substrate, and the products in your fertilizer cabinet. A separate AI advisor can help you discover and select real fertilizer products through web search.

The problem
Feeding schedules from manufacturers are generic — they don't know your pot size, your substrate, or your strain's actual appetite. Adjusting them by hand means cross-referencing three product labels, converting units, and hoping the mix is compatible. The calendar you built for veg doesn't automatically transition to flower, and forgetting to adjust is the easiest way to burn a plant.
Why it's hard to solve alone
Nutrient issues are the hardest problems to diagnose — deficiencies and toxicities produce similar symptoms, and by the time you see them the root zone is already compromised. A nutrition calendar that actually fits your setup prevents most of these problems from ever starting.
How GrowScope helps
The feeding calendar is built deterministically for your exact setup — no AI credits spent. You add your fertilizers to a cabinet, and GrowScope computes the schedule across the full cycle using that product list. A separate AI advisor with web search helps you find real products to add to the cabinet. When AI proposes feeding amounts, the same deterministic safety layer from Smart Watering clamps doses to the manufacturer's safe window.
How it works
- The feeding calendar is built deterministically — zero AI credits — from your strain, pot size, substrate, and fertilizer cabinet.
- Add your fertilizers to a product cabinet — GrowScope handles the math of scheduling them across the full cycle.
- A separate AI advisor with web search helps you discover and evaluate real fertilizer products to add to the cabinet.
- When the AI is involved in dose suggestions, the same safety clamping used in Smart Watering enforces manufacturer dosing windows — AI proposes, deterministic rules approve.

What you get
You get a nutrition calendar that runs from seedling to harvest, built for your actual products and setup, with safety checks that prevent out-of-range doses.
Frequently asked questions
Does the feeding calendar cost AI credits to generate?
No. The calendar itself is built deterministically — it spends zero AI credits. AI is used only in the separate fertilizer discovery advisor, which searches the web for real products you might want to add to your cabinet.
How does feeding safety work?
The same deterministic safety layer from Smart Watering applies here: when the AI suggests a dose, it is clamped to the safe range computed from the fertilizer manufacturer's dosing window. AI proposes — deterministic rules have the final say on anything going into the plant.
Can I use my own fertilizers, or do I have to use specific brands?
You add the fertilizers you own to the cabinet yourself. GrowScope does not restrict you to specific brands — the AI advisor helps you discover products, but what goes in the cabinet is your choice.
Does the calendar adapt if I change pot size or substrate mid-cycle?
The calendar is built from your entered parameters — strain, pot size, substrate, and products. If you update these parameters, the deterministic engine recalculates the schedule accordingly.
Can I add a fertilizer from a photo of its label?
Yes, on Pro. Photograph the back of the bottle with the camera or pick photos from the gallery — several bottles at once. GrowScope reads the brand and product name (4 AI credits per successfully read photo), then looks up the manufacturer's official data in the background (25 credits) to fill NPK and doses; the label photo becomes the product's avatar. The label is only a search hint — numbers come from official sources.
What happens when two fertilizers end up in one tank?
Base fertilizers of different lines that meet on the same day share one full strength instead of doubling it (an A+B pair of one line counts as one base); stimulants and additives keep their full rate. Plants watered with the same composition and rate on one day get one shared mix with the water and product amounts already summed.
Does GrowScope react to runoff EC?
Yes. If runoff EC is at least 1.3× the input EC two waterings in a row, Today suggests doses 20% lower; at 1.6× or more it suggests plain water with 20–30% runoff; at 0.7× or less, 10% more. Nothing changes until you tap to apply it.
