Growing cannabis indoors can be a highly rewarding experience, but it requires precise planning and careful execution. A suitable growing chart will help you maximize your plants’ yield by effectively managing watering, fertilization, and controlling pH and electrical conductivity (EC). Below, we present the best indoor growing chart you can find and a complete guide to help you interpret it in the best way, focusing on the growth and flowering phases.
⭐ What is a Cannabis Growing Chart?
A cannabis growing chart is a detailed plan that specifies the management of watering, fertilization, and monitoring of pH and EC throughout the growing cycle. The chart is divided into two main phases:
- Growth Phase (4-5 weeks)
- Flowering Phase (8-10 weeks)
⛳ Structure of the Cannabis Growing Chart
Growth Phase (4-5 weeks)
During the growth phase, your goal is to develop a strong root system and healthy vegetative growth. Below is a recommended program for pH, EC, and necessary products:
| Week | Water pH | EC (mS/cm) | Recommended Products | Comments |
|---|---|---|---|---|
| 1 | 6.0 | 0.5 | Root Stimulator, Growth Base Fertilizer | Introduce mild nutrients to start growth. |
| 2 | 6.1 | 0.7 | Growth Base Fertilizer, Root Stimulator | Increase the frequency and amount of nutrients. |
| 3 | 6.2 | 1.0 | Growth Base Fertilizer, Microelement Additive | Increase the dose according to plant development. |
| 4 | 6.3 | 1.2 | Growth Base Fertilizer, Microelement Additive | Adjust pH and EC to support robust growth. |
| 5 (optional) | 6.3 | 1.4 | Growth Base Fertilizer, Flowering Stimulator | Prepare the plants for the transition to the flowering phase. |
Flowering Phase (8-10 weeks)
In the flowering phase, the focus shifts to the development of flowers and buds. The growing chart should be adjusted to provide the necessary nutrients for optimal flowering:
| Week | Water pH | EC (mS/cm) | Recommended Products | Comments |
|---|---|---|---|---|
| 1 | 6.3 | 1.2 | Flowering Base Fertilizer, Flowering Stimulator | Introduce specific nutrients for flowering. |
| 2 | 6.4 | 1.4 | Flowering Base Fertilizer, Flowering Stimulator | Increase the fertilizer dose. |
| 3 | 6.4 | 1.6 | Flowering Base Fertilizer, Flowering Stimulator, Bud Fattening (PK) | Continue increasing EC to support flower development. |
| 4 | 6.5 | 1.8 | Flowering Base Fertilizer, Flowering Stimulator, Bud Fattening (PK) | Adjust pH and EC to maximize bud production. |
| 5 | 6.5 | 1.8 | Flowering Base Fertilizer, Bud Fattening (PK) | Maintain optimal nutrient levels for abundant flowering. |
| 6 | 6.5 | 1.8 | Flowering Base Fertilizer, Bud Fattening (PK) | Monitor flower development and adjust as necessary. |
| 7 | 6.6 | 1.6 | Flowering Base Fertilizer, Bud Fattening (PK) | Prepare for root washing, if necessary. |
| 8 | 6.5 | 1.6* | Nutrient-Free Water for 8 or 9-week flowering varieties; if longer, repeat week 7. | Start root washing to clean the plants before harvest. |
| 9 | 6.4 | 1.4* | Nutrient-Free Water for 9 or 10-week flowering varieties; if longer, repeat week 7. | Continue root washing and monitor flower quality. |
| 10 (optional) | 6.3 | 0 | Nutrient-Free Water | Finish root washing and prepare for harvest. |
