Benefits of a marijuana growing chart

Are there any advantages to having a marijuana growing chart? Many cultivators believe there are. Some include:

  • Keeping track of your plant’s developmental progress
  • Having a guide to show you what to expect from your crops
  • Monitoring feeds to avoid deficiencies or over-supplementation
  • Organizing all the cultivation information in a single place
  • Understanding your weed plants better so you can identify any issues swiftly

Overview of what a marijuana growing chart should include

A marijuana growing chart doesn’t only focus on one aspect of cultivation. Common sections on a chart include:

  • The conditions at each growth stage
  • Feeding
  • Light, humidity, and temperature requirements

The conditions at each growth stage concentrate on monitoring the development of the plant. Keeping track of the height, foliage, and other structural aspects helps you pick up on any issues.

A feeding chart serves as a reference point for supplementation. You can track how many nutrients the plant requires at different phases of the life cycle.

Cannabis requires different light, temperature, and humidity levels as it matures. A chart helps you stay on top of these needs.

Some charts also include information about the vapor pressure deficit, watering schedule, pest management, humidity and pH levels, and training techniques.

Building your marijuana growing chart

Creating a marijuana growing chart is straightforward if you follow a few simple steps. Gather as much information about the strain and seed variety as you can before outlining your chart.

Decide if you prefer a physical chart or a digital one. There are plenty of cannabis apps that have relevant sections for tracking cultivation. They’re ideal for tech-savvy growers.

Creating a timeline for your cannabis plant’s life cycle

The first step is considering the lifecycle of your plant. Take note of how long each development stage typically takes, and include any strain-specific timelines. The germination and seedling phases are usually standard, but things get tricky as the plants mature further.

Key milestones in a cannabis plant’s growth

How many developmental stages are there in a weed plant’s life cycle? From seed to harvest, it transitions through four distinct phases.

The first is seed germination, which occurs when a small taproot appears. The duration of this phase varies according to which method you use. Once the weed seed sprouts, it’s time to plant it, and within a few weeks, the first leaves appear. This is the seedling stage.

In the seedling stage, the foliage doesn’t display multi-fingered leaves associated with cannabis crops. Once the plant starts producing them, it enters the third phase.

During the vegetative stage, the plant matures rapidly before transitioning to the last phase. It’s during the final flowering stage that the buds form and become ready for harvest.

Estimating duration for each growth phase

A key element for your marijuana growing chart is working out how long each development stage typically takes.

Germination lasts around 1–7 days, and the seedling phase continues for 2–3 weeks.

The vegetative stage is more complex. Its duration is predictable with autoflower strains, but if the crop is photoperiodic, it depends on the grower. If there’s no change in the light cycle, the plants can remain in veg indefinitely. The average vegging duration is 2–8 weeks.

The blooming phase is strain dependent. Flowering typically ranges from 6–12 weeks.

Detailing nutrient requirements

Cannabis crops rely on certain nutrients to flourish. During each stage of maturity, these requirements change. The selected growing medium and strain play a role in the quantities required.

Understanding the nutrient needs of cannabis

Marijuana plants need a variety of macro and micronutrients. The former includes nitrogen, phosphorus, and potassium. The latter consists of calcium, iron, and magnesium.

Feeding your crops is a delicate endeavor. Providing too little may result in a deficiency, but excessive supplementation can cause nutrient burn. A feed chart is beneficial for tracking these levels.

Noting changes in nutrient requirements through the lifecycle

The needs of marijuana crops change as they grow. During the first few weeks of development, the soil provides all the nutrients they need.

Supplementation in the early stages could result in nutrient burn and damage to the plants. Wait until the crop is a bit bigger before feeding it.

Once the plant develops a few true leaves, indicating a transition to the vegetative stage, you can start offering supplements. There are mainly two ways to provide nutrients.

The first option is to offer nitrogen, phosphorus, and potassium (NPK) at a ratio of 2:1:2. It’s a moderate amount and not likely to cause nute burn. The alternative takes a more aggressive feeding approach. Provide an NPK fertilizer with a ratio of 4:2:3.

As the crops mature, the dosage can increase. When they’re about six weeks old, change the supplementation to an NPK fertilizer with a ratio of 10:5:7.

When the crops are almost ready to flower, drop the nitrogen and increase the phosphorus, so the ratio is 7:7:7. Keep this dose for two weeks into the final phase.

During week three of flowering, alter the NPK ratio to 5:7:10. When mid-bloom occurs, it should be 6:10:15, and in later bloom 4:7:10. Some growers opt to do a pH flush shortly before harvest.

Tracking light and temperature conditions

Environmental factors play a key role in the health of cannabis crops. Tracking the light, humidity, and temperature helps you regulate conditions for optimal development.

Every maturity phase has different lighting requirements, and the ideal temperature and humidity levels fluctuate. Having this information on your marijuana growing chart streamlines the process.

Documenting ideal light cycles for each growth stage

During germination, dark spaces work well, but once the seed sprouts, light is a critical factor.

During the seedling phase, plenty of light boosts growth. Many cultivators opt for CFL bulbs with a blue light spectrum. Using these for two weeks after the first leaves form is ideal. A light schedule of 16–18 hours is best, with nighttime ranging from 6–8 hours.

When the crops transition to the vegetative phase, switch to more powerful lights. There are various options, depending on your preferences.

HID or LED options are the most popular, but some select fluorescent bulbs. Most growers provide either full spectrum or blue light during this phase, as it’s when the most vigorous development happens. The day/night cycle is similar to the seedling phase.

When you flip the crops to flower, multiple changes must happen. Change to a red spectrum light and switch the light cycle to 12/12 in bloom.

Recording optimal temperature and humidity ranges

To maintain a healthy cultivation environment, the temperature and humidity levels need to be consistent.

Each strain has specific requirements. The average temperature required is around 68–77°F. Marijuana plants usually enjoy relative humidity (RH) levels of around 40–60%. In most cases, the RH levels should be high during the vegetative phase and low during flowering.

Customizing your chart based on strain and growth method

While these averages offer a great reference point and provide you with an idea of the requirements, it’s not a one size fits all. Tailor your approach to meet the needs of the strain you select.

Adjusting for different cannabis strains

There are several considerations when adapting your marijuana growing chart. Some of the factors include:

  • How large the plant grows
  • If it’s susceptible to any deficiencies
  • Which climate it prefers
  • Whether it’s photoperiod or autoflowering
  • How long the flowering stage lasts

Noting strain-specific growth considerations

After considering the various elements of the strain, record them on your chart to serve as a unique guide for your specific cultivar.

If your plant typically develops a bushy structure, include a pruning schedule. Crops that grow tall may require training.

If a particular strain typically produces heavy buds, take measures to support the branches. Understanding the cultivar’s needs is essential.

Modifying the chart for indica, sativa, or hybrid strains

The classifications of indica, sativa, and hybrid strains are fading out, but you need to accommodate them on your chart.

Sativa plants usually have a tall, lanky structure. Their foliage is sparsely spaced, and they take a while to mature. Indica crops are more compact, robust, and bushy. In many cases, they mature a bit faster.

When it comes to hybrid plants, it’s trickier to determine their structure, as it depends on which genetics are more dominant.

Adapting the chart for various growth methods

Building an accurate marijuana growing chart depends on whether you have an indoor or outdoor setup. Decide which growing medium you want to use. Certain ones require larger doses of nutrients and more frequent feeds than others.

Changes for indoor vs. outdoor growing

When cultivating inside, you have complete environmental control, but there are more elements you need to adjust. Outdoor growers can only control certain aspects.

If growing inside, your chart should include factors like:

  • Temperature
  • Humidity
  • Ventilation
  • Airflow measures
  • Lighting
  • Pest control
  • Supplementation
  • Soil pH
  • Estimated growth periods

Outdoor growers can include factors like:

  • Pest control
  • Soil pH
  • Seasonal changes
  • Estimated daylight hours
  • Estimated growth
  • Supplementation requirements

Adjustments for soil vs. hydroponic vs. aeroponic systems

Adjust your marijuana growing chart to accommodate your selected grow medium. Each option has advantages and drawbacks.

If you select a soil medium, your chart needs to include supplementation, flushing, pest control measures, and transplanting plans.

Hydroponic setups require less feeding and are less likely to encounter pests. When cultivating in aeroponics, equipment and timers should be on the chart.

Utilizing your marijuana growing chart

Once you’ve created the chart and selected your seeds, you’re ready to grow a cannabis plant. Put your research and hard work into practice.

Monitoring and recording plant progress

Document new developments on your marijuana growing chart. Include dates to determine a timeline. Observe how long germination takes and when the first leaves appear.

Documenting key growth observations

Record any changes in color or structure. This observation allows you to pick up any problems with your plant quickly.

Record the height, leaf quantity, and when the true leaves form. Follow up to see if the crops are developing as they should according to the average strain information.

Updating the chart as needed based on plant response

Every plant grows at its own pace. If your crops develop slower or faster than expected, adapt your marijuana growing chart. Similarly, change it if you encounter any issues on your journey. Pests, pathogens, diseases, and deficiencies can hinder plant development.

In some cases, growers choose to extend the vegetative stage to allow the crops more time to recover. Don’t be afraid to change the chart so it stays relevant to your cultivation situation.

Troubleshooting with your chart

One of the benefits of having a marijuana growing chart is being able to identify problems fast. It already contains all the information you need to figure out what’s wrong with your crop.

Check what sensitivities your plant has. Determine if it’s susceptible to any deficiencies, pathogens, or diseases. Analyze the symptoms and rule these issues out first. In most cases, a solution exists, as long as you diagnose and treat the problem fast.

Identifying potential issues using the chart

Are there any drawbacks to using a marijuana growing chart? While there are many advantages to this tool, you need to be careful to avoid certain issues.

One example is feeding. When you purchase nutrients, the dosage recommended on the bottle may differ from your chart. This issue occurs because the supplement amount is only for that specific product.

When using a blend of nutrients, stick to the chart. Adhering to instructions on the bottles instead may result in overfeeding.

Another issue that may occur is a difference in the average grow time. Each plant develops at its own pace, and some may be naturally more compact or large.

Sometimes, using a grow chart may lead you to believe there’s a problem with the plant when there isn’t.

Using the chart to guide problem-solving measures

This tool is useful for diagnosing issues with your crop. When using a marijuana growing chart, it’s easy to puzzle together any symptoms of deficiency or infestation. You can act quickly to remedy the situation.

Examples and templates of marijuana growing charts

Beginner growers might find creating a marijuana growing chart from scratch a bit daunting. Fortunately, there are templates available to make it easier.

Depending on what you prefer, there are different formats. Some are digital and come in the convenient form of a mobile app. Others are printable charts that you can stick on a wall.

The simplest form of this tool displays the plant’s life cycle. It describes what each development stage should look like and has accompanying images. It includes common issues and remedies during each phase. While useful to new growers, it isn’t detailed or specific.

The most common marijuana grow chart focuses on nutrients. It’s often called a feeding schedule. Growers use these in conjunction with a log or journal to track the plant’s progress while providing adequate supplements.

Comparing different chart styles and formats

Some growers prefer a blank chart where they log environmental factors and plant observations over time. Others prefer one that shows the expected height at each phase and issues the plant may be susceptible to with symptoms.

These charts include information on when to supply nutrients and the appropriate ratios.

Analyzing sample charts from successful growers

Many sample charts have a section for the plant growth timeline running horizontally at the top. Below that are light cycles and PPM, EC, and other variables. The different plants or strains feature vertically.

This chart is straightforward and allows you to cater to each plant individually. It’s also the most common.

Other charts feature a nutrient cheat sheet. Common deficiency symptoms are listed vertically. The corresponding nutrient required is listed horizontally.
