Growth charts are a very interesting tool when it comes to knowing the exact amount of fertilizer our plant needs and when to add it. Most brands have their own fertilizer chart for cannabis cultivation, but in this case we are going to focus on the Agrobeta feeding charts, an organic fertilizers company that stands out for its wide catalog of great quality products.
What is Agrobeta?
Agrobeta is a spanish company that manufactures fertilizers and additives, most of them organic, to boost and improve indoor and outdoor plants. Their ECO products are CAAE certified (Andalusian Committee of Ecological Agriculture), which guarantees that they are sustainable, environmentally friendly, reduce water footprint and control energy usage.
Agrobeta products are suitable for all types of crops and growers, whether amateur or professional. Regardless of their level, yields will be immediately improved. In addition, the wide variety of products (fertilizers, stimulators, boosters, additives, correctors…) is offered at a price that defies all competition. Therefore, this brand is an excellent choice to promote the correct development of plants.
How to interpret Agrobeta feeding charts?
Just like most fertilizer brands, Agrobeta has also launched its own growth feeding chart, which indicates the exact amount of fertilizers, additives or boosters the crop needs every week. As usual, Agrobeta makes a reference to the type of cultivation, growth and flowering weeks, the different products that can be used (Agrobeta boosters and fertilizers), the correct dosage and other data, such as water pH.
Below, discover the cultivation scheme for the two main ranges of Agrobeta fertilizers, which have contributed to the brand’s eco-responsible identity: the Black Line and the Blue Line. Additionally, a specific cultivation scheme has been developed for Agrobeta flowering boosters, within which some of the company’s flagship products are included. It is intended for individuals who wish to combine Agrobeta additives with their usual fertilizers from other brands.
All Agrobeta cultivation schemes divide:
- The growth phase in three weeks 18 hours of light
- Flowering in seven weeks (12 hours of light)
- Harvest, or flush, in two weeks.

In addition to the products applied, it will be necessary to ensure adequate environmental conditions.
Parameters to respect for Agrobeta feed charts
- In the growth phase, pH will be adjusted to 5.5; before gradually increasing to 5.8. As for the flowering phase, it requires a pH between 6 and 6.2.
- Indoors, it is recommended to maintain a temperature between 20 and 25 degrees Celsius. At night, make sure to decrease the heating by a few degrees, to simulate natural climatic conditions as closely as possible.
- Adequate humidity conditions will be established for each stage, with humidity levels between 40 and 70% for the vegetative phase, and 40-50% during flowering.
If Cancerbero is applied, it should be diluted separately to avoid clogging your drip irrigation system, regardless of the cultivation phase.
For all Agrobeta cultivation schemes, always alternate between a fertilizer watering and a pure water watering.
Agrobeta feeding chart: boosters and additives
This table is intended for horticulturists who wish to combine these prestigious additives with their usual fertilizers from another brand. It groups together a selection of four flowering stimulators that have acquired great renown among growers in Spain. Their application will result in an explosive production of buds, incredibly dense and compact. Agrobeta boosters are compatible with fertilizers from any other manufacturer, whether from Agrobeta or others. Below is a simplified explanation of when to use some of the Agrobeta boosters and in what quantity:
| AGROBETA FEEDING CHART: FLOWERING STIMULATORS | |||||||
| Week | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
| Phase | Flowering | ||||||
| Mega PK (56-35) | 0.5 g/L | 0.5 g/L | 0.5 g/L | 0.5 g/L | |||
| Genesis | 2 ml/L | 2 ml/L | — | ||||
| Terminator | 2 ml/L | 2 ml/L | 2 ml/L | 2 ml/L | |||
| Tricoma | 1 ml/3 L | 1 ml/3 L | 1 ml/3 L | 1 ml/3 L | |||
Mega PK (56-35)
Mega PK (56-35) is an extremely phosphorus-rich (56%) and potassium-rich (35%) flowering stimulator. It allows the cultivator to obtain bulky and compact buds, while also reinforcing the plant’s natural defenses. Additionally, it is particularly soluble, facilitating its absorption by the plants.
Genesis
Genesis is a powerful flowering booster that allows to accelerate the flowering phase and promote the formation of bulky flowers. In fact, the plants will be shorter, generating longer lateral branches and a shorter internodal distance. It contains 3% phosphorus, 5% potassium, and 20% organic elicitors.
Terminator
Terminator, as its name suggests, is used in the last weeks of flowering to compact and harden cannabis buds. It is composed of 2% nitrogen, 6% phosphorus, 6% potassium, 2% magnesium, and 8% ascorbic acid. This allows stimulating the plant by metabolizing its reserves. Consequently, the harvest weight will increase.
Tricoma
Tricoma is a stimulator based on 1% nitrogen, 20% phosphorus, and 25% potassium. It also contains small doses of chelated iron and magnesium. The plant receiving this product will be sturdier, and its flowers more compact. This product promotes the production of trichomes, making it perfect for concentrate enthusiasts.
Agrobeta feeding chart: Green Line

Agrobeta feeding chart: Black Line
For those growers who wish to apply exclusively products whose components come from living matter, Agrobeta has designed the Black Line. These 100% organic products (from living matter) contain amino acids obtained by enzymatic hydrolysis, nutrients, biostimulants, humic and fulvic acid. With it you will be able to see plants grow in full health and respectful of the environment.

Agrobeta feeding chart: Blue Line
The Blue Line is a range of bio-organic fertilizers, made from algae and enzymatic extracts that function as powerful biostimulants. Spirulina microalgae provides all the amino acids, polysaccharides, phytohormones and trace elements necessary for the life cycle of plants. The enzymatic extracts, on the other hand, guarantee a perfect absorption of these nutrients. Blue Line consists of two phases: A (growth) and B (flowering).

Other Agrobeta feeding charts
In addition to these cultivation tables, which include the brand’s most emblematic fertilizer lines, Agrobeta offers other cultivation schemes. These are specific tables for autoflowering varieties, coco growing, hydroponics or the application of mineral or organo-mineral fertilizers. In our grow shop online, you will find an almost unlimited choice of fertilizer brands and growing products.
A few tips
It’s very important to highlight that these indications aren’t straight science (as stated in the Agrobeta charts) because each plant has its own development and you need to observe the plants, read into their needs and give them what they require, otherwise, you run the risk of over fertilizing them.
It’s very important to recognize the different stages of the plants and apply the right dose at the right time; no need to follow the chart strictly. For example, if you feel that the plants are overly fertilized and the Agrobeta growth chart says that you need to spray them with water and fertilizer, follow your own instincts because experience should predominate over the chart indications.
Not all plants develop at the same time, therefore, using a flowering fertilizer on week three could be counterproductive if the plant hasn’t reached that stage yet. As a final conclusion, Agrobeta feeding charts are only a guide and reading into the plants’ needs is way more important.
