How long is the vegetative stage for Autoflowers? ›

Autoflower cannabis average time from seed to harvest

With 5-6 weeks of vegetative growth and around 9 weeks of bloom it can take 15 weeks or more for a feminised strain to reach harvest.

Geoflora VEG Makes the Vegetative Stage Simple

Nitrogen is the most important nutrient to have abundantly available to your plants during the vegetative stage, as this nutrient is the staple component for vigorous root, stalk, stem, and leaf growth.

The longer you keep your plants in the vegetative stage, the bigger your plant will be, resulting in bigger yields from plants that were vegetated longer.

Vegetative (3-16 weeks) Flowering (8-11 weeks)

However, indoor growers can manipulate the lighting and can keep plants in a vegetative state until they run out of room or if they want to take cuttings during an extended period (they want lots of cuttings). Most growers will run plants in a vegetative state anywhere from 3-8 weeks.

During the earlier stages of plant growth, the fan leaves should only be removed if they yellow or dry out. However, once the plant begins to flower, you can trim off some of the fan leaves. However, don't remove more than half of the fan leaves, because they are still needed by the plant.

Vegetative period

After sprouting, it is recommended to water frequently - 2 times a day. But the amount of water should be small - about 200 ml. The fact is that at this time, the root system of marijuana is still very poorly developed and simply cannot extract moisture from the soil.

Give Your Plants More Light – If you're growing indoors, then as long as you give your plants more than 14 hours of light each day, they'll stay in the vegetative stage. But you can actually give them 24 hours of light each day and it's like “forcing” more growth.

These youngsters feature a short stem and two rounded cotyledons. Eventually, the first “true” leaves will form. Over the subsequent 2–3 weeks, seedlings will start to mature and produce a large number of fan leaves—structures required for photosynthesis. This marks the beginning of the vegetative phase.

What is the fastest yielding vegetable? ›

Over fertilization can actually decrease growth and leave plants weak and vulnerable to pests and diseases. It can also lead to the ultimate demise of the plant. Signs of over fertilization include stunted growth, burned or dried leaf margins, wilting, and collapse or death of plants.

Switching from Veg to Bloom

Plants need at least 13 hours of light each day to stay in veg – a few 'long' nights may be enough to trigger budding. Plants begin budding when they get at least 12 hours of 'uninterrupted' darkness each night (12/12). This must continue until harvest.

To some degree, more light translates to fatter buds and higher yields (you'll need to pay attention to the distance between your grow light and plants or your plant may suffer from light burn). Increasing light intensity is the most effective way to fatten up buds.

Generally March and April, when the soil begins to warm, are the best months to begin sowing many hardy annual vegetable seeds outdoors including broccoli, cabbage, chard, carrots, peas and parsnips.

It ends when plants begin the transition to budding, whether because they have reached their mature size or because the conditions have triggered the start of reproduction. That's the time to switch a bloom stage fertilizer – excess nitrogen can inhibit the development of flowers.

Vegetative phase

We recommend defoliating vegging plants just before you switch them to bloom: Start by removing big, hand-sized fan leaves first. These tend to overshadow almost anything below them, making it hard for light to properly penetrate your plant's canopy.

A bud consists of a short stem around which immature overlapping leaves are present. Vegetative buds can also give rise to new plants.

Removing these fan leaves opens up light and produces better air exchange to the lower canopy. Healthy leaves at the bottom of the canopy should be kept to trap valuable light from being lost and wasted. The more quality light a flowering site receives, the larger it will grow and the faster it will mature.

Trimming Boosts Harvest

At the flowering stage, the plant experiences rapid growth, and any significant pruning at this stage will lead to plant shock. Although defoliation is still effective, it should only be done in the first period of flowering.

Should I trim all fan leaves before harvest? ›

Usually, growers trim the fan leaves weeks before harvest, which is a period that leads to senescence, a phase in the plant cycle when the larger leaves start fading away. It is safe to start removing these dying leaves and continue until harvest. However, the main trimming processes commence after harvest.

Timing Is Key: When To Flush Your Plants

If you're growing in soil, begin flushing between one and two weeks before harvest. If you're growing in coco, flush your plants for up to one week prior to harvest. If you're growing in hydro, your plants only need to be flushed for one to two days.

For soil growers, plants can be fed once every second or third watering. If plants are fed with every watering then nutrient buildup and lockup becomes a problem causing stunted growth, “crows foot” (curling downwards of the leaves), leaf burn, deficiency symptoms, burnt and damaged root system and decreased yields.

Plants, however, do not stop growing when they are being flushed. Rapidly expanding buds can be seen even while the flush is removing nutrients.

What stimulates vegetative growth? An abundant supply of nitrogen, sufficient water, high air humidity and moderate temperatures stimulate vegetative growth. For good vegetative growth, it is important that the plant can properly take up the nutrients in the soil.

Epsom salt – actually magnesium sulfate – helps seeds germinate, makes plants grow bushier, produces more flowers, increases chlorophyll production and deters pests, such as slugs and voles. It also provides vital nutrients to supplement your regular fertilizer.

It is recommended that you wait until your plants have at least four nodes before topping them, and most growers recommend topping the plant above the sixth node. Nodes are the part of a plant that connects new stem offshoots with older growth, which can form a branch, a leaf, or in the case of cannabis plants, a bud.

In the vegetative stage, LED grow lights should be between 12-24 inches away from the top of the canopy. During this stage, more light is needed for photosynthesis, so the light source should be located closer to the plants. As the plants progress through the flowering stage, their demand for intense light decreases.

One easy way to make seeds germinate faster is to presoak them for 24 hours in a shallow container filled with hot tap water. Water will penetrate the seed coat and cause the embryos inside to plump up. Don't soak them for longer than 24 hours because they could rot. Plant the seeds immediately in moist soil.

Waiting longer to harvest gives the trichomes ample time to develop. But the longer you wait, the more highly intoxicating and sedative your flower will become. This is especially true for indica strains, but even sativa strains can become sedating.

What vegetable takes the longest to grow from seed? ›

Which of the common vegetables to plant take the longest to germinate? Asparagus has a relatively long germination period, taking from 21 to 28 days to do so. Parsley is another slow-runner, with 18 to 24 days, and okra takes 15 to 20 days.

1. Asparagus (Asparagus officinalis) Probably the most popular of the perennial food plants, asparagus can take two or three years to become well established but then can continue producing spears for at least 15 years or so.

Spinach takes around 30 days from sowing to harvest. It can be sown at the beginning of every month to get fresh green spinach leaves by the end of the month, which can be used from salads to pasta.

Symptoms of excess nitrogen include thickened and sometimes cupped leaves with atypically deep green color. Overfertilization can cause leaves to turn brown, gray, dark green, or yellow at margins and tips or overall. Affected foliage may wilt temporarily or die and drop prematurely.

When plants receive too much nitrogen (N), they become more attractive to insects and diseases. It can also cause excessive growth and reduce the strength of the stems.

Plants do best when watered about three times a week, factoring in the rain. If the plants are seedlings, water twice a day until established. But don't just water without thinking. Feel your soil!

If growing autoflowering seeds, the cannabis vegetative stage tends to last for the first 5 weeks or so. After that, the autoflower genetics initiate the cannabis bloom stage. There is little that you can do to control the cannabis vegetative stage with autoflower seeds.

Week 3: Vegetation Well Underway

At this point, your autoflower will be well into the vegetative phase. You'll notice new fan leaves forming, which will ramp up photosynthesis. Aim for the following environmental factors during week 3: 50% RH.

The start of the vegetative stage can be considered as soon as the first Cotyledons (first two small circular leaves) appear on your seedling. The seedling will take a couple of days to completely emerges from the soil and after up to 2 or 3 weeks you will see the first true leaves.

How long will it take for my auto to start flowering? In general, autoflowers stay for 4 weeks in the vegetative stage, so about 4 weeks. Then your auto will start developing flowers for 3 weeks, and fattening up the buds for the last 3 weeks.

How do you keep a plant in vegetative stage? ›

Give Your Plants More Light – If you're growing indoors, then as long as you give your plants more than 14 hours of light each day, they'll stay in the vegetative stage.

During flowering, cannabis doesn't need much nitrogen, but instead needs more phosphorus (P) and potassium (K). This is why you will usually come across two types of cannabis fertilisers—those for vegging, and those for flowering. The above applies to both autoflowers and photoperiod cannabis.

Just like photoperiod plants, autos have low initial nutrient requirements which increase steadily as the plant grows. Again, as with photoperiod plants, Nitrogen rich nutrients are required initially to allow the auto to grow healthily in the vegetative growth phase. As the autoflower ages it starts to approach bloom.

18/6 light cycle for autoflowers

The 18/6 autoflower light schedule is very common. It means 18 hours of daily light is followed by 6 hours of darkness. Many growers also use this light cycle for vegetative growth of their feminised cannabis seeds.

Overall, autoflowering takes about 8-14 weeks from seed to harvest. This is much faster than “photoperiodized” strains.

And since autoflowering plants have short vegetative phases and often grow shorter than photoperiod strains, you'll typically want to give your autos at least 18 hours of light. This allows for robust growth, without overspending on energy.

Vegetative period

After sprouting, it is recommended to water frequently - 2 times a day. But the amount of water should be small - about 200 ml. The fact is that at this time, the root system of marijuana is still very poorly developed and simply cannot extract moisture from the soil.

Regular autoflowering plants are small, yielding between 10 and 50 grams per plant. You cannot expect a strain with a fast and short flowering time to produce more than 30 grams but super autoflowers can yield 200-300 grams if you give it the perfect environment.

Considering the above, autoflowering strains from RQS have a seed to harvest time of between 8–14 weeks. This is much faster than the vast share of photoperiod varieties, however, genetic variation means some strains take longer than others.

Not too many people routinely top their autoflowers, but those that do tend to do so after/around 4 weeks of growth. One of the dangers of topping autoflower plants is that the grower misses out on the main central bloom. This can often account for around 20% of the total harvest.
