The initial thing to do is get the large fan leaves out of the way so that you can see the rest of your plant clearly. These don’t have much value except for compost and can be discarded. The smaller bud leaves, however, have trichomes on them and are great for making edibles and hash oil. Carefully remove these and put them safe, working around the bud until you reach the sugary coating.
With all indoor photoperiod plants, you can decide when they go into the flowering stage. You do that simply by changing the amount of light they are exposed to. In the vegetative stage you have probably been using about 18 hours of light and 4 hours of darkness.
This is generally the most nerve-wracking time for newbies but it’s not something you should be afraid of. Our first big tip is to try not to touch the flowers more than you have to. You want to keep those delicate trichomes intact as much as possible and handling them can cause a lot of damage.
Next it’s time to change this completely with 12 hours of light and 12 hours of dark. From now on, your flowers should start to develop the buds that are going to make up your next cannabis harvest.
This is normally a good time to add extra nutrients to the soil as your plant is using up an awful amount of energy simply growing. Experts recommend you do this during the first week and also indulge in some light stress training (LST) if you want to improve the size of your crop.
All the energy now is going into bud growth and you start to smell that tell-tale aroma as the buds get bigger and juicier. This smell is down in no small part to the trichome growth. The rest of the plant will have stopped growing completely now and you don’t have to worry about training the stems.
Once you’re ready to hit the flowering stage indoors, simply change the lighting regime to 12/12.
To help you out, we take a long, hard look at flowering week by week in pictures. While plants can vary slightly in how they look, this should give you a great idea of what to look out for. It can help you plan better for harvest time.
In just the space of a few weeks your plant will have increased in size by about a half but this will now begin to slow down. On the female plants where you noticed hairs last weeks, buds will start to form. We’re now entering a pretty important stage and one where you need to be vigilant.
There’s no doubt that the flowering stage is important when it comes to producing a great crop of cannabis. Over the next several weeks, you’ll find those buds developing and it’s a pretty exciting time. Of course, it’s vital to know what to look out for as things develop so that you know when …
If it hasn’t happened yet, your plants now might develop the known marijuana smell. Make sure to use a carbon-filtered airflow system. Your airflow system is important at this point and fresh air needs to be constantly flowing into your grow room. In this phase, your plants will need a lot of CO2 (carbon dioxide) for growth and health.
The flowering stage is the moment we all have been waiting for. For you, as a professional grower, this is the most important part of growing marijuana. Let’s discuss how you can take care of your flowering cannabis and grow the best yield ever.
In week 3 or 4, the first real buds will show instead of only hairy pistils. The growth of the plant will now slow down a lot – it’s important to watch out for the health of your plants at this point. A few dead leaves are normal (ex: if they do not get enough light). You do not want a major disease at this point so it’s also important to watch your nutrient levels and observe your plants closely to ensure nothing strange is happening.
Some pros trim their plant leaves at this point (defoliation) so their plants can focus mainly on bud growth. Make sure to leave enough leaves to support your plant’s health! The leaves are fueling the plant’s system and therefore bud growth.
When it comes to managing humidity during the flowering stage, keep your grow room between 45% humidity. While cannabis plants do love moisture, especially in the cloning and vegging stages, in the flowering stage you run the risk of powdery mildew on your buds with humidity anywhere about 50%.
Nutrient burn could be a source of declining health of your plant. Make sure not to over-feed your plant with nutrients. You will notice that the tips of the leaves will seem burned if you over-feed your plants.
To introduce your plants to this new stage in their life cycle, make sure you are using the right flowering grow lights. Gradually change the light cycles until you reach a 12/12 hours ratio of light and darkness. Again, growing indoor gives you the perfect opportunity to create an environment that suits your plants best. It’s important to take advantage of indoor growing instead of being dependent on the rhythm of the sun. The better your cannabis flowering stages are, the better your yield will be.
The first 1 to 3 weeks of the flowering stage are a transition phase and your plants will still be growing. Your plants could double their height at this point depending on the type of strain you are using.
When your plants switch from the vegetation to the flowering stage, the growth will eventually get slower. When the plants start to develop flowers (so called buds), it is time to treat them differently. This means changes in light and different nutrients for the flowering stage.
These flowering stage tips will take your cannabis production to the next level. It's the moment we've all been waiting for. Weeks in the making, now is the most important part of your plants' lifecycle. It's make-or-break for the success of your crop. Follow these simple steps to ensure you maximize your yields.
