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.
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.
Once you’re ready to hit the flowering stage indoors, simply change the lighting regime to 12/12.
This is the time when color changes start to take place in the flower. Those fine hairs which form the pistils may be turning darker or even amber colored. The trichomes, which were a bit harder to see, may start to turn milky. This means you’re not too far off being able to harvest your crop.
There are some things that you must do before you actually harvest, however. The first is called flushing. This basically removing the nutrients from the soil and replaces them with pH balanced water. It’s done normally about two weeks before the big day. This is not actually for the benefit of the plant but to get rid of nutrients that might well affect the taste/flavor of the final cannabis product once you harvest.
We hope that showing you the cannabis flowering week by week in pictures gives you a much better idea of what lies ahead and what to look out for. Understanding the various phases of cannabis plant development comes with practice and experience so don’t be too hard on yourself if you get it wrong first time. Treat it as a learning experience.
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.
Most strains come with their own nutrient schedule so it’s important to check this and keep to it to avoid over or underfeeding your crop. If it isn’t provided with the seeds you bought, you can always check online.
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.
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 …
While plants have been growing and prospering like crazy in the vegging stage, your plants will now be more prone to problems. Everything that happens from here on out will affect your yield – for better or for worse.
In weeks 4 to 6 of your cannabis flowering, the buds will get bigger and fatter. Once the flowers are showing as small white pistils (white wispy hairs), your plants will need more phosphor and potassium. Both are important for a good bud formation. The nutrients support flowering and fruiting.
A final, supremely important thing to note about lighting during the flowering stage: once you start switching to the flowering light cycles – never go back. Never expose your plants to light in the dark phase of the day. You do not want to confuse your plants or make them switch back to the vegetation phase. This could dramatically impact your yield. It is the un-interrupted darkness that leads your plants to flower. Make sure this darkness is definite – not one minute of light in the night! Use a programmable timer to make sure you don’t forget when you need to turn your lights on or off, and be sure to test your settings and confirm they’re correct before trusting it on your precious cannabis plants.
Be sure to get a good thermo-hygrometer, measure your grow room daily, and employ the use of a dehumidifier if you see your humidity start to creep up into a dangerous range. A standard 30-pint dehumidifier like this one will work for most setups from small grow tents up to a 500 square foot grow room. For bigger grow rooms (1000 square feet+), consider stepping up to a 70-pint dehumidifier like this one.
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.
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 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.
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.
It might be tempting to cut big branches, but your plants need all their power and health they can get right now. Never taste the freshly developed flowers – let them grow in peace. You might bend the plants and tie them down to create a more horizontal table-like shape instead of a Christmas tree shape.
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.
