The cannabis vegetative stage is an essential evolutionary period for the growth of cannabis plants. During this stage, cannabis produces leaves, branches and roots but no buds. The amount of light that the plant receives determines when it enters flowering.
When growing photoperiod feminized seeds indoors, you can control the length of time in veg with 18 or more hours of daily light. If you grow photoperiod feminized seeds outdoors, the length of day dictates when flowering starts. With autoflower seeds, however, it’s the age of the plant that determines when flowering begins.
Therefore, cannabis vegetative time is a period where the plant prepares itself to enter the flower and start producing buds. Knowing how much time your cannabis should spend in its vegetative cycle is essential for obtaining maximum yields from whatever strain you are growing.
Be sure to give your plants enough time so they can properly develop during this stage before you start inducing bloom or triggering pre-flowering development signs to signal harvest time.
Basic Tips On Vegetative Cannabis Plants
Having healthy and vibrant vegetative cannabis plants is an essential part of producing an abundant, high-quality crop. During the vegetative stage, it is vital to ensure that the plants are given a nutrient mix that is nitrogen-rich.
Providing the perfect balance of nutrients to meet the plant’s needs during this stage of growth can be difficult to achieve but will result in significantly improved yields. Plants should also be regularly checked for any signs of pests or disease and kept in optimal environmental conditions – particularly with regard to lights and temperatures – as fluctuations can have a devastating effect on cannabis growth.
How Much Water Does Cannabis In Veg Need?
For young cannabis plants in their vegetative stage, it is important to not over-water them. These plants have very low transpiration rates and consequently demand less moisture from the roots. Overwatering can lead to poor root development caused by waterlogged and oxygen-deprived soil, which can ultimately stunt their growth.
To avoid this, some growers make use of moisture meters to determine accurate soil moisture readings so that they know just how much water their plants need.
It’s also important to note that cannabis grows more quickly during the vegetative stage than most other crops, meaning that the amount of water needed may increase as the months go on in order for the plant to retain its health and keep growing at its expected rate.
What Kind Of Nutrients Are Best For Vegetative Cannabis?
Nitrogen is an essential nutrient to any plant, yet it’s especially important for cannabis during the vegetative phase. Nitrogen helps stimulate stem and branch growth and encourages lush green foliage.
Too much nitrogen, however, can be detrimental to the health of your cannabis plants at the veg stage. In high levels it can burn the fragile leaves of a young plant, reducing its ability to grow properly in later stages.
Organic forms of nitrogen are great options as they keep things natural and there is less risk associated with them than chemical-based fertilizer supplements. Always carefully read fertilizer labels or nutrient product descriptions so you know what kind of dosage and frequency you need.
For beginners, opting for an organic all-purpose fertilizer may work best because these fertilizers tend to have a balanced range of nutrients and are easier to use in moderation. Remember, knowing how much and when to feed your cannabis plants will make all the difference between good yields and potential damage!
How Often Do You Feed Nutrients In a Vegetative State?
The vegetative growth stage is an essential stage in a plant’s life cycle, and the nutrients you feed your plants during this period will have a big impact on how healthy and productive your crop will be.
If you are growing organically in soil with slow-release organic nutrients, then you may not need to add any extra nutrients to the veg state, although adding a light top dressing of general-purpose bloom nutrients, later on, can be beneficial for keeping your plants healthy.
What Is The Ideal Temperature / Humidity For The Vegetative Stage?
The ideal temperature and humidity level for plants during the vegetative stages of cannabis growth can vary depending on a number of factors such as room temperature and local climate. Generally, many growers aim for temperatures between 23-25°C (73-77°F) during lights-on periods.
Dropping to a few degrees lower when the lights are switched off. Keeping relative humidity (RH) levels at around 60-70% or higher is recommended for veg growth as it helps with absorption and retention of moisture when root systems have yet to fully develop.
It’s important to note that RH levels should be reduced during flowering, as high humidity can result in mold or bud rot in later stages. Monitoring both temperature and humidity throughout the entire growing cycle ensures an optimal environment is maintained, which makes all the difference in achieving successful harvests.
Adjusting RH according to the specific plant variety being cultivated will ensure they receive their best opportunity to thrive and produce quality outcomes.
How Much Light Should Cannabis Plants Receive In Vegetative Stage?
When it comes to lighting for cannabis plants, PPFD (photosynthetic photon flux density) is the most popular measure of light intensity. Measured in units of micromoles per square meter per second (μmol/m2/s), it allows growers to decide what light level is suitable for their plants given their stage of marijuana growth.
To make things easier, many grow light manufacturers have developed specific recommendations for cannabis plant hanging heights and PPFD readings at various stages of growth. For example, seedlings are able to tolerate a light intensity between 200-400 μmol/m2/s while larger plants can cope with gradually more powerful lighting options.
It’s important that growers understand and apply the correct light levels throughout the different stages of the marijuana growth cycle in order to maximize yields and avoid stunted development or even complete failure of fruit or flower sets.
Carefully monitoring, adjusting, and managing plant lighting based on measured PPFD levels should result in healthy and high-yielding crops when harvesting time rolls around.
Can I Veg Cannabis With Fluorescent Lights?
Yes, cannabis with fluorescent lighting can be a great way to boost yields and provide good results. High-wattage compact fluorescent lights are particularly useful since they offer sufficient PPFD light intensity at the plant canopy.
These lights are also great for starting seedlings, as they provide lower levels of ambient and directional light which promote healthy growth in the early weeks of vegetation. For larger plants, however, you may need to switch to an option that offers more intense illumination such as LEDs further down the line.
Overall, fluorescent lights are a low-cost effective way to keep your garden going during the vegetative phase.
What’s The Best Veg Light For Cannabis?
When it comes to choosing the best veg light for cannabis, there are several options available. For those on a budget, HPS/MH lights tend to be the cheapest option. However, LED grow lights have become increasingly popular in recent years due to their high efficiency and long-lasting performance.
LED lights are used by many professional growers because they produce higher cannabinoid levels compared to HPS/MH lights. Additionally, fluorescent fixtures like compact fluorescents can also provide good results and serve as another option for those looking for a lower-cost solution.
What Colour Of The Light Spectrum Do Cannabis Plants Like During The Vegetative Growth Phase?
The light spectrum for cannabis plants during the vegetative growth phase should be rich in blue wavelengths. This provides the optimal environment for good vegetable growth. Blue light helps to increase leaf and branch structure, promoting a more compact and bushy growth form.
Red light can also be beneficial for veg growth but can cause the female plant to stretch out. Later on in bloom, growers may want to include plenty of red wavelengths alongside orange, yellow, and green for optimal results.
When To Prune, Top And Trim Cannabis In Veg?
When it comes to pruning and trimming cannabis plants during their vegetation period, some growers swear by it while others choose not to.
While the removal of leaves is generally not recommended when it comes to young cannabis plants as they are solar panels that can provide energy for future growth, many experienced growers do like to remove certain leaves that may be blocking light from reaching lower bud sites as those marijuana plants get larger.
The logic behind this practice is that ultimately the overall yield will increase due to the more distributed exposure to bright light allowing all of the bud sites to develop properly.
How Long Does The Cannabis Vegetative Stage Last?
The vegetative stage of cannabis growth is considered the foundation for a healthy and successful harvest. During this stage, cannabis plants focus their energy on building up healthy roots and leaves, rather than focusing on developing flowers.
The length of the vegetative phase depends on two main factors – the type of cannabis seeds you use and how you grow them. Autoflowering cannabis seeds tend to have a virtually predetermined vegetative cycle.
Generally, these types of seeds will enter the flowering/blooming stage after about five weeks or so in the vegetative state – regardless of light cycle changes or other environmental conditions aimed to extend vegetable growth.
How To Tell If Your Plant Is Ready For The Flowering Stage?
Germinating cannabis seeds and determining when it is ready for the flowering stage requires knowledge, experience, and a keen eye. Knowing how to tell if your plant is ready for flowering is crucial in optimizing your yields.
The vegetative growth of cannabis generally lasts 4-6 weeks when growing photoperiod feminized seeds indoors. This timing largely depends on the cannabis cultivators’ personal growing style and method used, though SOG growers will usually reduce the length of vegetative growth down to 1-2 weeks while SCROG growers might take up to 10 weeks.
Cannabis Vegetative Stage Most Common Problems
To ensure a successful cannabis vegetative stage, proper planning and optimal grow room conditions are crucial. Despite these measures, some problems may still arise. Here are a few of the most frequent issues that growers may encounter.
Cannabis Plant Starting To Bloom In Vegetative Stage
It can be a surprise when a cannabis plant that is in the vegetative phase starts to show signs of blooming. This tends to happen more often with a prolonged veg growth period, and autoflowering strains are prone to suddenly setting bloom, as their genetics will naturally decide the timeline.
When this occurs, it usually requires the grower to switch from veg to bloom light cycle, such as 12/12. This should allow the plant to do what it’s set out to do from the beginning, but if stopped too early or too late it may compromise how well your marijuana plants grow and develop.
Cannabis Leaves Drooping In Vegetative Stage
Drooping leaves in a cannabis plant’s vegetative stage of growth is a fairly common issue most growers face at one time or another. The cause is often due to overwatering, using too much water in the growing medium, and nutrient solution.
This mistake can cause root rot, stemming from the root system being submerged in water and not having a chance to breathe and get air. Too much water within the medium can cause oxygen depletion, ultimately leading to droopiness.
To avoid over-watering, growers should monitor their watering schedule with a hygrometer (moisture meter). It gives the user an accurate measure of moisture content in the soil or other growing mediums so that they can accurately gauge when it needs more or less water, avoiding issues such as drooping and wilting leaves.
Cannabis Plant Turning Light Green
Yellowing or light green vegetation on cannabis plants could be an indicator of nitrogen deficiency. During the vegetative phase of growth, the right nitrogen level is essential for healthy and full optimal growth. Without the proper amount of Nitrogen, leaves will start to yellow and lose some of their usual green colorings.
A good way to identify a nitrogen deficiency is by examining the discoloration pattern. If it’s isolated spots or along one side/corner of your plant, then it usually points to too little nitrogen.
Slower Plant Growth Than Usual In the Vegetative Stage
Slow plant growth during the vegetative stage of cannabis growth can be a cause for concern, but it doesn’t necessarily indicate a problem. Certain genetics may have slower growth than others, so all growers should be aware of which strains are typically slower growing in order to understand any discrepancies.
What To Do If You Lose Track Of The Light Cycle?
If you’re an indoor grower and have lost track of your light cycle, don’t panic. It’s not a big problem and there are some simple steps you can take to get back on track. The first step is to reset the timer and switch off all artificial lights. This will help to remind mother plants of the natural circadian rhythm and allow them to acclimatize, which may only take a few days.
