The vegetative growth is said to last for 2-4 weeks depending upon the energy produced by the plant. The growth of the plant is related to the leaves size and photosynthesis system. Bigger the leaves, better the photosynthesis system. Better the photosynthesis system, faster the growth. In an ideal condition, your plant can also grow up to 6 inches per day.
The presence of tiny white hairs at the bud sites is the indication that the flowering has begun. They are visible after 10-14 days after you initiate the flowering stage. Now it is time to remove male plants if you have any.
Having an extraction fan on the ceiling promotes the airflow. You have to keep in mind that your fan should change the air in your garden at least every five minutes. Of course, this largely depends on the size of the room and the power of the fan.
On the other hand, HPS emit light on the orange and red end of the spectrum and a small amount of blue, and therefore more preferable during the bud formation and flowering stage.
You switch to the flowering stage by changing the lightning to 12 hours of light and 12 hours of darkness.
Hydroponic Grow Room Setup-Vegetative phase of marijuana growth.
Since the beginning of the modern hydroponic system, people have been using the HID (High-Intensity Discharge) which consists of HPS (High-Pressure Sodium) and MHL(Metal Halide Lights). LED has been a recent development in the lighting field.
To make sure your cannabis plant grows accurately and completely, you have to be cautious about the light they need. Lighting is an important part of the Hydroponic Grow Room Setup. From blue wavelength to the red and orange one, I will walk you through how these are used at the different growing stages. But, before that, why do we need the light?
We know that they need 18 to 24 hours of light per day during this phase, but it is recommended to use a timer for less than 24 hours. The lighting need depends on several factors like the temperature of the room, reflectivity, spacing, maturity of the plant, the distance between the plants and lamp, and the performance of the lamps, etc.
There are also CFL lamps, but they are not as efficient as others.
There is another type of light used for Marijuana Cultivation; Compact Fluorescent Lamps, also known as CFL. They don’t produce as much heat as the HID lights, which allows them to be placed closer to the plants. Usually used to compensate for the blue light during the vegetative growth, CFL is now available in different spectrums.
Now that we have established LED the King of Cannabis Lighting, let’s move forward.
LED lights are considered best for this process, as the HPS lights are not so active in a blue/green part of the spectrum and hence, not very useful. As for the MH light, they emit quite a great deal of heat which is not a suitable condition for the marijuana plants to grow in. (Since they start growing in spring)
If you’re using auto-flowering seeds, they will shift to the flowering phase whenever they are mature enough, regardless of the light cycle.
These, obviously, produce only the female buds, with great growth and quality. You might think that the potency of the weed may get compromised, but that’s not the case. In fact, the end flavour and potency is better than the weed produced from non-feminized seeds.
Hydroponic Grow Room Setup- switching to flowering (budding)
There is no correct answer to the question- when to switch to flowering.
LED lights are preferred because they give you better control and use less amount of energy than what is required for HID Lamps. You can use LED lights during all stages of development as they provide a spectrum for every phase. Moreover, they don’t require additional investment in the form of ballast and don’t present any heat and space issues.
Out of all the mentioned lights, LED takes away the prize with its measure benefits and great value.
When they reach the flowering stage, we need to change the light cycle to 12 hours of light and 12 hours of darkness. This would be enough to trigger the flowering phase. You can start doing this once your plant reaches 12-20 inches of height.
Once the required conditions are set for flowering, you will notice the change in 1-2 weeks. Another note for all you cultivators; Make sure you get rid of the male plants, as they only create pollen which will impregnate the female plants with seeds. Nobody likes a seedy weed!
Your Hydroponic Grow Room Setup requires the right kind of lighting for the complete and proper growth of your weed. Vegetative phase demands that 14% of the light should be blue light which helps to limit the stretching.
Light for the vegetative phase.
Metal Halide lights come the closest to the regular light and are preferred for the vegetative phase of the plant due to the blue wavelength of light produced. It promotes bushy and compact growth and is, therefore, better for the early stage of growth.
Plants use CO2 and light for photosynthesis, and the heat is given out from the lamps. You need to have a good ventilation system to bring in the CO2 rich air while taking out the CO2 depleted air.
A cheaper way to go about the process would be to use a mixture of baking soda and vinegar or dry ice. Just remember not to use fumes from a propane heater as they contain some dangerous gasses and can cause a fire hazard.
You may notice that your plant grows slower in the flowering stage. This is because energy is utilized for the flowering process. You have to make sure that your plant is at least 6 inches tall and has a minimum of four sets of leaves before moving on to the flowering stage.
You have to understand why the flowering stage is so crucial. It is the time where all your “high” ingredients are produced by the plant. All the THC, CBD, and CBN is the work of the flowering phase. This means your flowering phase will decide the potency of your strain.
Before you start with this process, make sure your Hydroponic Grow Room Setup is complete and working.
The lightning for the flowering stage has already been discussed, but you have to ensure that the 12 hours of darkness is perfect without any interruptions from daylight, room light, or any other light. Imperfect lightning, other than moonlight, delays the flowering process, and if it continues, can hamper the flowering stage completely.
