Roses Lab is Yolia's laboratory dedicated to the rose. It is not a generic fertilizer recipe with a flower photo: when you choose this specialty, the engine changes its priorities (it strengthens flowering, pigments, structural calcium, aroma and silicon), offers the rose's own goals and reads the climate of your location to decide what is worth doing and what is worth waiting for.

What you receive is a process: a diagnosis, a strategy of goals separated by phases, a formula made with preparations that you make yourself (ferments, infusions and teas from common ingredients such as beetroot, eggshell, herbs or seeds), a logbook to record what happens and recalibrations when the evidence justifies it. You do not receive a jar or a bottled product.

A cut rose is a very demanding plant: it produces long stems and large flowers in a few weeks and repeats cycles of sprouting and cutting. That rhythm consumes carbohydrate reserves and strains the root. That is why in Roses Lab the work starts below, in root, absorption and reserves, before pushing the flower.

Heat is the classic enemy of the rosebush. The floriculture literature describes that at high temperatures the rose speeds up its development, the bud ripens faster and the flower tends to come out smaller and with fewer petals. That is why Roses Lab includes a specific heat-recovery objective, and the engine reads the maximums of your area and the alerts for your location (intense heat in the field from 35 °C; estimated greenhouse overheating from 36 °C).

Color and aroma depend on compounds that the plant makes with energy (sugars from photosynthesis) and minerals, and which degrade with excessive heat and radiation. The color pigments (such as anthocyanins and carotenoids) and the volatile compounds of perfume are secondary metabolites: they are produced better when the plant is healthy, hydrated and not overloaded. Genetics sets the ceiling; management and nutrition determine how close the plant gets to that ceiling. Yolia works on that second part.

Priority is a real relative weight of the engine: above 1.00 the function is reinforced, below 1.00 it is kept gentle. It is not an improvement percentage or a promise of results.

Before mixing anything, the engine reads the stage you declare. That is why the same plant gets a different strategy when rooting than when flowering.

The same specialty works for very different scales. What changes is the scope, the follow-up and the price, not the engine.

These are the ten real contexts the engine evaluates. If your case meets one, those functions rise in priority; if it meets several, they are combined. If you do not declare a piece of data, the engine flags it as missing instead of inventing it.

What Yolia does with an alert. If there is an alert crítica, the system holds back the field application. If it is high, requires a balanced review and lowers the boost mode to “balanced”. The forecast comes from Open-Meteo (7 days, hourly) and the multi-year climate history of your location; a location confirmed on the map is needed for this to work.

Ventana de cosecha y corte de emergencia. Yolia calculates a theoretical date of the optimal point according to the real progress of your program and, depending on the destination (local, national or export), suggests cutting 0, 2 or 5 days earlier. If a serious alert (frost, storm, heavy rain, strong wind) falls on the final stretch, it recommends bringing the cut forward. Límite honesto: it is a calendar-based estimate, not a reading of your plant; Yolia does not yet analyze photos to decide the harvest point.

When a critical alert falls on the week of application, Yolia holds back the field application instead of pushing ahead out of inertia. For a rose, that can mean waiting a day and avoiding a foliar application before a gust of wind or heavy rain; it is a decision the system explains to you with the alert that caused it.

It is what rose growers ask about most, and where it is easiest to exaggerate. The truth is that vase life is decided in three places: in cultivation, in harvest and in the chain afterward. Yolia only works on the first.

On the crop side, floriculture recognizes that nutrition before cutting can have an influence: calcium and cell wall structure, potassium and nitrogen balance, and carbohydrate reserves in the stem. The effect varies by variety and is not always large. That is why in Yolia it is a declared objective and is evaluated against your control plants, not a promised number.

If someone promises you “X more days in the vase” without comparing against a control plant of your own, be wary. What we can give you is the method to check it in your own batch.

A Yolia module is a unit of plant biochemistry: a controlled process (fermentation, infusion or extraction) with declared ingredients, times, pH and yield. The engine chooses modules from a catalog organized into four product families, measures how much load each phase can bear and places them at the right physiological moment. If two modules clash, they are not removed: they are separated into different phases.

They are real modules from the catalog. Which one is chosen in your case, in what phase and in what quantity depends on your plant, your stage, your climate and your logbook; the exact quantities are only shown in your formula, not on this page or in the Sandbox.

Without evidence, the system cannot correct anything: that is why the logbook is not decoration. You record notes and photos throughout the program and follow a few control plants —a representative group that you observe closely— to compare against the rest. With 1 plant, that whole plant is followed; up to 4 plants, all are followed; from 5 to 20, 3 are followed; from 21 to 500, 5; and from 501 to 5,000, 10.

Recalibration, no silent changes. When it is recalibrated, all 21 engines are run again in full with your new evidence. The previous formula is never deleted and each change leaves a visible event that you can consult. There is a manual recalibration, an automatic notice (when uploading a note, it only recommends and requires at least 14 days since the last adjustment) and, only in Resin & Trichomes Lab, an automatic recalibration with a verified photo. The plans include 0 (Diagnosis), 1 (Targeted formula) or 3 (Advanced laboratory); an additional one requires a new quote.

The vase test is not an automatic Yolia tool: it is a practice we recommend you record as text in the logbook to compare against your own evidence.

The value of the case is not the result but the logic: instead of doing more, the system becomes more careful when the crop is under stress.

A commercial fertilization program may have years of published trials and guaranteed analysis; Yolia does not have that yet, and that is why it is labeled a prototype. A field advisor can see your greenhouse with their own eyes, and Yolia cannot. What does make Yolia different, and you can verify it for free in the Sandbox, is that it reads your climate, separates goals by phases, blocks dangerous combinations, shows why it decides each thing and leaves a record you can audit. We do not compare Yolia against other brands because we do not have independent tests to do so.

One-time payment per program, processed by Stripe, with no automatic renewal. The large price is the one for 1 plant (the lowest); with more plants the price rises according to each card's list, and with each additional goal $2 USD is added to the one-time payment before the scope factor. Every Yolia formula is honestly marked as a prototype, still on its way to full experimental validation.
