What are you seeing?Here Yolia compares temperature, humidity, and other air data with the plant's current stage.
Why it mattersYou don't have to memorize numbers — Yolia lets you know when a weather combination deserves your attention.
How to think about itFirst check whether any alert is active; if there isn't one, you don't need to analyze every number separately.
Very simple example30°C can be perfectly tolerable in one context, and problematic if the air is also very dry and the root cannot replace water in time.
What are you seeing?Temperature, humidity, radiation and wind together modify the evaporative demand, the thermal balance and the response of the plant's stomata.
Why it mattersConnecting these signals prevents drawing a weather-risk conclusion from a single isolated data point, like temperature alone.
How to think about itCheck current conditions, active alerts, the coming hours, and the confidence/source of the data, in that order.
Very simple exampleThe same 30°C temperature can be normal on a humid day and risky on another day with very dry air — the number alone is not enough.
What are you seeing?The advanced reading adds the physiological mechanisms at play (transpiration, VPD) and separates the observed data from the weather inference.
Why it mattersA weather alert must be mechanistically plausible, traceable to its source, and proportional to the data's real quality.
How to think about itIt distinguishes variable, mechanism, interaction, uncertainty, limitation, and what additional evidence would confirm the real risk.
Very simple exampleAn alert's confidence depends directly on the source of the weather data used — not all sources have the same certainty.
Option 7 — Root flushing (soil flushing)
When to use it: if you notice signs of salt or nutrient overload in the substrate (burnt tips, white buildup on the surface, or before a strong recalibration). It is a reversible option: it does not change your formula, it only cleans the substrate so the next application works better.
- Calculate the triple-water rule according to your pot's liters (P5): for example, a 15L pot needs 45L of clean water for a complete flush.
- Adjust the pH of the flushing water to 6.0–6.5 before applying it — a pH outside that range does not release accumulated salts well.
- Pour the water slowly and let it drain completely before pouring more — never apply it all at once.
- Repeat the pouring until the water coming out of the drain runs crystal clear, with no color or visible sediment.
- Sentinel's mandatory handbrake: after the flush, Yolia freezes irrigation for 72 to 96 hours so the substrate dries and the roots breathe oxygen before resuming normal irrigation.
Important: Don't water again before the 72–96 hour window ends, even if the substrate feels dry on top — that rest is necessary for the root to breathe oxygen after the flush.
