When you embark into growing your own marijuana at home you will come to understand the two main phase of growth. The first main phase after germination and seedling is the vegetative growth phase of weed. This phase is where your ladies go through adolescence and mature into adults. The second phase and final phase prior to harvest is flowering which we will cover in another article.
A rule of thumb being a base equivalent power of 400W can cover a specific area. An approximate number of 16 females can germinate. At the beginning of the process, we do not know which ones will survive. It will be helpful to plant almost twice as many plants (8 in total) even if we have to use smaller containers due to lack of space.
Cloning is a technique that consists of cutting pieces of a branch of a mother plant (cuttings or clones) and beginning a process of developing a root. Obtaining a portion of the mother plant we can be sure a new plant of the same genetics. Cloning during the vegetative growth phase of weed avoids the need to plant seeds. You will see in our other posts the challenges regarding germination.
They are just weeds but aren’t they just finicky.
What should we do after our weed plant sprout?
Once the seeds have sprouted, we place them in the final pots and administer a minimum of 18 hours of light per cycle. This regime can be continuous (24 hours of light). In the first phase, it is helpful to use a fluorescent light assembly (colour 33) or to move them farther from the normal sodium light, although this will cause them to gather excessively.
We recommend to start the process with the assembly of two or three 120 cm fluorescent tubes (which will can also serve for the vegetative growth phase of weed as well as the cloning phase) Keep them in degradable peat pots until the shoots measure a few centimetres (5-10 cm.) and then transplant them to the final pots under sodium light or you equivalent LED. Thus, by avoiding the gleam produced by sodium light, we gain a few vital centimetres.
If the sprouts start to droop a lot, they may need a wire or similar type of support to bolster themselves.
What are the light cycles for the sprout phase of weed growth?
It is good practice to ensure they receive the continuous light regime (or a minimum of 18 hours) from the moment they sprout. It is even better to put the peat pots or similar under the light as soon as you bury the seed as the lack of light could cause excessive moisture and facilitate the formation of fungi. Ignore that last statement if you are germinating your seeds with a process other than directly in soil.
Once the plants have had 24 hours of light in the final containers, you will grow them to a height of between 20 cm at the lowest and 38 cm at the highest.
Initial irrigation is done according to the needs and conditions of the environment. Since the initial soil mixture nourishment is sufficient at this point, it will not be advisable to fertilize until they have reached a hearty height. It may not be necessary because if the soil mixture is made well, it will support this first phase of the process. Nutrient should only be added if you see that the plants have become pale or lose vigour.
What are the light cycles for the weed vegetative growth phase?
The rule of the green thumb is that for plants to have the desired height, it will take about a month. If you plant different species, you will have different growth patterns which we can unbalance the rule mentioned above. You will be forced to twist or cut the tips of those that shoot in height while you are waiting for the small ones to reach the ideal height.
It is not necessary during this phase of the process to provide more care than the supply of water, the monitoring of the height of the lights and the rotation of the plants on themselves periodically. As well as the continuous rotation of those that grow more on the sides. Your garden should be as uniform as possible. When all the plants have the desired heights (20-38 cm.), It will be time to change the light regime (12 hours of light-12 hours of darkness) which will force them to bloom. You must gather your cuttings (clones) before moving to the flowering phase if you want to perpetuate the system.
Keep the ball rolling with cloning during the growth phase
Remember with four plants legally allowable in Canada if you want to never pay for your weed again, cloning is the way to go. We will discuss in a further post about how you can increase your yield through “Training.”
To ensure that your ladies get the appropriate amount of light too (absolute) dark it is a good idea to purchase a timer for your lights and your ventilation systems. Remember the12-hour timer will cause the flowering phase if the timing is off you risk sending your weed plants back into the vegetative state. It will be essential that the night period is absolute dark, so you have to check that there are no slits through which the light leaks from the outside if it exists.
The use of fans, essential during vegetative growth, will not be necessary during the night unless the humidity is excessive. It is also not advisable to connect the indoor fan until the shoots do not measure a few centimetres (or not focus directly). The extractors that provide fresh air and extract the odour should work as long as the lights are on and free to choose at night
