Flowering small cannabis plants

These solo cup plants were able to survive their entire lives in a small container. I wouldn’t recommend a solo cup because they tip over easily, and plants are prone to nutrient and root problems once the flowering stage begins (the root space is just way too small, even when doing 12-12 from seed or using an auto-flowering stage).

Make sure to let your young marijuana plants get a minimum 2-3 weeks in the vegetative stage before changing them over to flowering. Your plants will be healthier and will start flowering at the same time as if you started 12-12 from when they first sprout.
I have changed cannabis plants over to the flowering stage from seed, but no matter what the light schedule, plants don’t start flowering (making buds) until they are about 3 weeks old. Initiating a 12-12 light schedule at 3 weeks old from seed is as early as I’d recommend for this technique, if you choose to use it.

But like this extreme girl to the right (less than a foot tall and grown under CFLs), I’ve experimented starting the plants on 12/12 from seed to keep plants REALLY small.
Plant Training Techniques – Make your plants grow how you want
Some strains of cannabis will naturally start flowering after about 3 weeks, and you don’t need to do anything with light schedules to cause that to happen. These strains are known as “autoflowering” or “Ruderalis” strains.
The other disadvantage to overly small plants is their inability to recover well from problems: you have fewer leaves as a ‘buffer’ so the plant can’t bounce back when something goes wrong such as a pest attack. In a too-small container, as roots get more root-bound, cannabis plants have a harder time using nutrients efficiently, and may start showing nutrient problems.
Many Growers Who Want To Force Cannabis Plants to Flower at a Young Age May Be Interested in Auto-Flowering Strains – No Need for 12-12 and Often Much Better Yields!

But does the 12-12 from seed technique work to give you a faster harvest, and if so, what are the results?

Learn what it means to give your plants "12-12 from seed" to force them to start making buds early.

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.

Remember: Only female plants will produce buds. You can make sure to have female plants by using feminized seeds.
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%.

You do not have to think about tying your plant down at this point anymore. However, you might consider holding your buds up and close to the light if they are too heavy for your plant.
Around weeks 6 to 8, your plant will have stopped vegetative growth completely and only work on the buds. A few leaves might turn brown at the bottom now and this is perfectly normal. Your plants will be sensitive to a lack of nutrients at this point. Watch your pH levels to make sure your plants get all they need.
Finally! Buds with substance. White pistils will be sticking in all directions and the buds themselves will be bigger every day. Congratulations! You have come a long way and your plants are rewarding you. Here’s the best tips to follow during the flowering phase to get you here:
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.
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.

Before spotting a marijuana flower, you will still want to support your plants in the growth stage as much as possible. Once the flowers are showing, you want to optimize for light and nutrients. Now you can, and should, switch to 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.
