When do plants flower outdoors

Joined: May 6, Messages: 28 Likes Received: Hey guys, I started growing my plants indoors at the end of April, and then i moved them outdoors about a month ago. They are growing well, but I am wondering when they will start to flower if i leave them outdoors.

There are also cannabis plants that aren't light-sensitive, called autoflower varieties, that will automatically flower on their own at a particular point of their maturity independent of how much light they're getting.

These plants tend to have much shorter life cycles, which is appealing to some gardeners. Harvesting happens when the plant's flowers have fattened up but before the very cold weather comes on, typically by mid to late fall. Speaking of life cycles, let's talk about the plant's stages of growth and development. This is where we see the importance of timing once more, since outdoor cannabis growers try to map out the growing season and find the sweet spot for optimal plant development.

If you're growing from seed, the first step in the life of your cannabis plant is germination. Once the seed has sprouted, it will immediately grow two little round leaves, called cotyledon leaves, that will be responsible for delivering energy to the seedling until it starts to grow the more familiar fan leaves we all know and love. As far as timing when to sprout your seeds, a general rule of thumb is on or around the Spring Equinox.

If you're not growing from seed but instead buying clones, they'll already be in the seedling stage when you get them so you don't have to worry about germination. Seedlings are baby plants. Whether you've sprouted your own seed or bought a clone, during this first stage of life the plants are delicate and sensitive.

Folks in cooler climates often elect to start plants indoors to keep them safe and warm, waiting to plant outdoors until they're somewhere between 6 inches and a foot tall and strong enough to handle the environment outside. Even in warm climates, many growers like to start their plants indoors to give them a leg up since seedlings are susceptible to pests, disease, and mold.

In cooler climates, growers should wait on putting plants in the ground until there is no danger of overnight frost, and plenty of sunshine. Of course, you could always grow your plants in pots or containers. Lots of outdoor growers elect to use pots and other containers, and they offer the added benefit of being able to bring the plants out during the day and inside if nights tend to be cold. The vegetative stage is when the plant's growth will really take off.

For several weeks, it will grow more foliage, reaching ever upwards to that glorious summer sun. During this phase, growers might consider topping and training their plants to encourage outward growth. This provides more even distribution of light to the leaves while also managing overall plant height.

Growers should note that plants that are forced to flower early will not grow as large or produce as much as plants that are allowed to develop over several months. Those growing cannabis in warmer climates can have rolling harvests, planting marijuana crops back to back and forcing each to flower early.

Doing this allows them to harvest buds every few months, so the difference in plant size will not significantly impact their overall yearly yield. Some warmer climates allow growers to cultivate cannabis at any point in the year.

In these climates, there is no specific time when a grower should force their plants to flower. However, areas farther north, such as along the American and Canadian border, experience their first frost between September and October. This early frost date makes it impossible for growers to let their plants finish flowering naturally. In these places, cannabis growers should force their plants into the flowering stage between July and August.

The idea behind forcing an outdoor marijuana plant to flower early is reducing the hours of light it receives to twelve or fewer. However, that is not the only factor in getting cannabis plants to flower early. Below is a summary of several methods to use when forcing outdoor plants to flower. The first step for any grower that plans to force their plants to flower early is to choose a strain that finishes fast.

Some strains, like Blue Dream , take as many as twelve weeks to finish flowering. This extended growing time makes it difficult for growers to let their plants finish flowering, even if they force it to flower early. Instead, growers should choose a plant that has a short flowering time, like Green Crack.

This strain takes as little as seven weeks to flower. Growers can allow the plant to stay in the vegetative stage for longer, increasing its size before it reaches the flowering stage. One of the simplest ways to force a cannabis plant to enter the flowering stage early is to cover it with a tarp. Growers will need to use poles and stakes to prop up the tarp so it does not damage the plant, but also does not allow any light inside. Growers must be sure their plants are getting enough airflow under the tarp to prevent mold.

It is also important that they watch the temperature under the tarp. If the sun is beating down on the outside of the tarp, it could raise the temperature under it high enough that the plants get burned. This is another reason adequate airflow is critical to the success of this method. Growers with a more complicated setup can use an automated roof to cover their plants. Typically, this is done by growing plants in a shed or similar structure. The structure can be fitted with a manual roof cover or one that is set to a timer that automatically closes at a set time every day.

Growers will need to be sure their grow area is fitted with fans and ventilation to ensure adequate airflow when the roof is closed. For growers who want to keep things simple, moving plants inside to a prepared growing area every day is a good option.

Of course, this is only an option for growers who are using growing containers rather than growing their plants directly in the ground.

The growing area will need to be prepared similarly to the structures mentioned above, with fans for ventilation and a thermometer to monitor ambient temperatures. Growers who need to force a quick harvest should consider pollinating their cannabis plants. Once the plants have been fertilized, they will be ready to harvest in about one week. However, the flowers should be at a certain stage before pollination takes place. Learn how to take care of your plant in this stage to harvest quality buds!

Growing outdoors, plants will start the flowering stage when the days grow shorter, usually when Autumn is coming. The flowering stage in Cannabis plants usually goes from 8 to 11 weeks, depending on the strain. The flowering period for Indica strains is typically around 8 weeks, but it may take up to 10 weeks.

Sativa strains may take up to weeks. Typically, hybrid strains will take up to weeks to fully develop. For more information and tips on how to find out, read our full article on determining the sex of a Cannabis plant.

Light contamination may cause your plant to slow the budding process or even to revegetate go back to veg stage or start producing hermaphrodite flowers. On the other hand, high temperatures also affect the plant negatively. Relative humidity measures how much humidity is present in the air expressed as a percentage. Higher levels of humidity may cause problems such as mold and fungi. When the plant starts to bloom, the concentrations of P and K must be increased progressively, while the N concentrations are lowered.

That is why there are specific fertilizers for vegetative growth and flowering. Other secondary nutrients will be necessary for the correct development of the plant. Finally, the micronutrients are necessary but in a minimum concentration. So which is the best feeding plan or nutrient application schedule for my plant?

Even when growing organic, usually having your plant in plain soil is just not enough for the plant to produce big fat buds.

Several brands of fertilizers offer fertilizer kits specially formulated for each stage with the necessary nutrients. Read this article to learn more about nutrients for Cannabis plants in the flowering stage. Water your plant regularly with clean, safe and water.

Certainly, using chlorine-free or filtered water leads to better results. Always avoid overwatering and watch for good drainage. How to know when to water a Cannabis plant? Ventilation and airflow are key for Cannabis plants to thrive and grow healthy. In this stage, they need air not only to breathe and grow their bodies but also good ventilation to avoid the formation of mold, fungi, and rot. A good fan moving the air inside your growing environment helps a lot, but beware not to point it directly to the buds.

An exhaust fan is great for increased ventilation and air movement, this also helps lowering humidity. If the exhaust fan is not enough, a dehumidifier is definitely the best and easiest solution for keeping humidity at range. Most nutrients are available for the plant in the growing medium only between this range of pH. Are you growing in your garden soil? In pots with soil? In buckets? The bigger the container is, the more chances of getting a bigger plant you have.

Remember to transplant your tree before the flowering stage begins to avoid stressing the plant or accidentally damaging it. Share your work with a community of like-minded individuals while learning to grow better. From week plants stretch and grow in size and height. This phase is also known as the transition phase, as plants experiment drastic changes these days. Plants stretch and may double their size in this phase. Towards the end of the third week, the plant starts forming its bud sites in the plant nodes where the main stem and the branches meet.

Look for clusters of female preflowers. All those places where white pistils have been growing are future bud sites.

You may lightly defoliate your plant during this phase, but be careful not to touch or damage the forming bud sites. Look at the color of the fan leaves and the general look of each plant to have a better idea of their health and needs.

The fan leaves should be vibrant green, not too light nor dark. For example, yellow and discolored leaves may indicate a deficiency, while dark and clawing leaves may indicate nutrient burn. Track these changes in the Grow with Jane app as soon as you notice them for a better chance of diagnosing your plants correctly and in time to heal them! Most importantly, to eliminate these at this point is usually easier than doing it later into the flowering stage.

From week plants stop growing in size and start growing, fattening their buds and darkening their pistils. At this stage, you should continue to train your plant if you started some weeks earlier and you should be seeing some changes. In addition, if you need to tie or move your plants, bear in mind that now they are putting all their efforts into growing buds, so any stress or damage may slow that process.

Remember to continue to move your lamp or plants so they maintain their adequate distance. Now your plants are growing at a fast rate and they need their feeding and watering schedule to be followed for optimal results. If you notice lots of leaves yellowing or any changes in color or texture in the new or old leaves, check for nutrient deficiencies or burn!

In the last few weeks, buds gain the most weight. They are sticky to the touch and can be very smelly. Most importantly, buds are now covered in trichomes, which are rich glandules for secreting THC and other cannabinoids.

These are responsible for the stickiness in the colas. Depending on the strain and the breeding, these buds may have strong aromas, reminding of fruits, flowers, and spices for example.

In this stage of the Cannabis plant, pistils may show white, cream and brown colors. They also start curling inwards and they get covered in trichomes. Similarly, trichomes also change colors and you should pay close attention to these changes because they are one of the best clues for knowing when is the best time for harvesting. Flushing a Cannabis plant is basically to run a lot of water through its growing medium soil, for example to get rid of the excess of salt and mineral nutrients.

This action forces your plant to use up any amount of nutrients previously absorbed. The result will be buds with better flavor and aroma. The excess of fertilizer in your Cannabis plant may result in buds which are harsh to the throat when smoked and.

Flushing with clean, room temperature water will help to get rid of fertilizer excess in the soil. Two weeks before harvesting is usually a good moment to start flushing your plants and watering with water only and no fertilizers until the harvesting moment.

Regarding the amount of water needed, a good rule is to calculate 3 times the volume of the pot. For example, if your pot is 5 liters, you can flush with 15 liters of water per pot. An easy way of doing this is carefully placing each plant in a big bucket, barrel, shower, or bathtub and add the water gradually to the soil, without drowning the plant. The excess water will slowly drain from the bottom of the pot. A good visual sign is that, in the beginning, the water coming from the bottom of the pot will be dark and will gradually turn to a lighter color.

Place a container bucket or similar under the pot for collecting the excess water, be careful or this may result in a bit of a mess. By running this process once in each plant, most of the salt buildup should flush away from the substrate.

All explained in a simple way, with pics and a Step by step harvesting guide. If your plant is showing clear signs of nutrient burn, you should definitely do it. If it was grown organically it may not be necessary. Some growers swear by it and some just skip this process. Thanks for reading and commenting! Have a nice day! Hi Juanette! The duration of the flowering period is more important to achieve a higher yield and even higher THC concentrations.

Harvesting just in time, not early nor later, will have more impact on the quality of your flowers. The rest may be up to environmental conditions, especially if growing outdoors. This means you may harvest sooner than later and avoid strong winds, rain, or even snow, which may damage outdoor crops severely. Follow a nutrient schedule for the flowering stage and avoid interruptions in the hours of darkness if growing indoors.

My leaves a changing to purple n orange its outside i live in florida ive never put chemicals what so ever whats your recommendation my buds are beautiful smell great just fist time grower. There are Cannabis phenotypes that show orange and purple on the leaves and buds. Drops in temperatures sometimes trigger these changes. If trichomes are still transparent, wait a few more days and check again until you start seeing white trichomes, maybe some of them amber. Thanks for reading and happy harvesting!

Hi Brandon! Hey everyone…started them late not until june didnt get very big.. Hi Robin! I hope you enjoy your harvest! Thanks for commenting! I started flowering, and one of my plants has started budding but are not filling out and the leaves are curling up.

What do I do? Hi Herman! Thanks for commenting and happy growing! Hello, yes you can! Some panels have veg and flower switches for adapting to each stage.

Always set to 18 hours of light and 6 hours of darkness for veg stage. Pushing plants to flower stage since its been 10 weeks. Lights are blue and red. Its been 2 weeks and I dont see any signs of hairs. How long does it take? Some Sativa strains may take more time to develop and start flowering. Most plants start showing preflowers in the first or second week after switching, this might take a little longer.

Add nutrients intended for the flowering stage, as nutrients for veg have high levels of Nitrogen and this may delay and hamper flowering. Temperature and humidity are fine, keep them that way. Make sure that the dark periods are completed without any interruptions or light filtrations, this may confuse your plants and also delay flowering.
