Jogging also known as the jungle of green or JOG technique is a useful way to maximize the yield from your crop. It is very effective in a low grow space as well.
Typically indoor growers who can control their light cycles will use either 18 hours of light per day or 24 hours of light per day. There are mythical claims that a darkness period is needed but there is no evidence to support. What is in dispute is whether the extra light hours bring a great deal of benefit compared with 18-hour light.
A couple things that any grower should be aware of are that leaves are solar panels. You might be twisting and directing the branches but the plant knows better than you when and where it needs leaves, leave them alone. If a gentle pull on the leaf doesn’t cause it to give way immediately then it is healthy tissue. Usually you will only want to remove browned leaves. With a thick canopy under indoor light the lower growth will yellow and die, this is because the plant isn’t getting much light there and steals the nutrients from these now unneeded leaves. This is nature at work and not always a sign of too much or few nutrients.
During vegetative growth you will want to use a fertilizer that is high in nitrogen at full strength. Nitrogen is used by the plant to grow stems, leaves, and other green parts and so is absolutely essential to the vegetative phase of growth. As always you should begin with the manufacturers suggestions for the period of growth you are in when adding fertilizer and then adjust up or down based on how your plants respond.
Different techniques have developed for training plants. The goal of training a marijuana plant is to optimize yield with the available light and space. Outside a plant in the middle of a clearing with a full year of vegetation can probably be left to do what it wants and give great yields. Indoors the light is more precious and many growers are using small cabinets. They just train their plants to utilize the space they have.
Another thing that is important to know is that the tops of the plant produce the most potent and largest flowers. Most training techniques focus on maximizing the number of those top flowers and on removing smaller lower flowers the plant will direct all its energy to the larger tops. How much difference different training techniques make is debated but trimming lower growth that is far from the light is universally agreed to improve yield. Any time you bend a branch horizontally it will cause the plant to produce a hormone that encourages lateral growth.
The vegetative growth cycle is about growing the plant mass in preparation for flowering. Outdoor you will have several months of vegetative growth. Indoors you can have as little as a week (if using clones), 4-6wks (typical), or as much as you want.
With the jog technique you will use wires shaped into “U”‘s to hold down the stem into the desired positions as you gradually shape it around the perimeter of the pot. The goal is to make the plant entirely fill the pots space with top buds. No matter how much training you do a plant will have a genetic maximum bud capacity that can not be exceeded. Training will help you reach that potential but nothing can allow you to exceed it.
The adult life cycle of the marijuana plant consists of two stages of growth. Vegetative and Flowering. The plant determines which of these stages of growth it should be in through the presence of a flowering hormone (phytochrome) which is sensitive to light. As long as light levels above 12-14 hours are maintained the flowering hormone will never be present in high enough levels to induce flowering in the plant. At any point during the plants life if the light is on for more than 12 hours a day it will cause the levels of flowering hormone to be reduced and the plant to revert to the vegetative growth stage. If a plant is reverted during flowering by irregular light patterns it can cause stress in the plant and stress can cause hermaphroditism. A plant can be maintained in vegetative growth without being allowed to flower indefinitely with no adverse effects.

For example, if the fall season begins in August, and one’s planning to vegetate the plants for 5 months, the plants should be sown in March. The duration of the vegetative phase greatly depends on the strain and preference. Generally, when growers want massive plants, they’ll leave the plants in veg for a long time; if short plants are desired, they’ll be planted closer to the beginning of fall. Autoflowering strains, which derive from Cannabis ruderalis genetics, have a very short vegetative phase due to their development in cold climates. Therefore, they should be planted during the 2 months with the most hours of sun as this will allow these short and fast-growing plants to thrive.
Temp: Outdoor plants can handle hotter temperatures up to 38ºC when the roots go deep into the cool ground. The perfect temperature for indoor plants spans between 21-29ºC. During the night, the temperatures should be slightly cooler, between 17-21ºC.
Humidity: During the vegetative phase, cannabis plants can handle higher humidity levels. Around 60% RH is recommended.
Ventilation: Air circulation is necessary during the veg; both indoor and outdoor growers need to provide the plants with a gentle breeze for them to inhale CO₂, and exhale O₂.
Nitrogen! The main ingredient which cannabis plants require during the veg is nitrogen. The N-P-K ratio (nitrogen-phosphorus-potassium) should be around 2-1-1, however, growers have different preferences and recipes. As a rule of thumb, when the leaves maintain a healthy green colour and don’t fall off, the levels are just right.
In most indoor operations, there is limited space for plants to veg. Indoor growers often prefer indica and autoflowering varieties because they’re relatively short. Cannabis plants with classic sativa traits are difficult to grow as they take over the grow space like those plants in Jumanji. Sativa plants can stretch up to 3x their height after they’ve been put into bloom. To control height during the vegetative phase in indoor environments, growers use SOG and ScrOG techniques to train the plants to grow in specific directions. These techniques are quite advanced; novice growers should get a couple harvests under their belt before attempting these methods.
pH: The pH levels should be around 6-6.5 for soil-grown cannabis. For hydro, 5.5-5.8 is optimal.
Sativa-dominant, photoperiodic strains, however, can reach up to 400cm. Depending on the strain’s genetics, the amount, shape, and size of the leaves will also differ. For example, indica varieties evolved in harsh environments between the Hindu Kush mountain range and desert climates; as a result, they developed a “wide finger” leaf structure as a defence mechanism to retain water and protect buds from the blazing sun. On the other hand, sativa strains develop “narrow finger” leaves, which help them to respire in the tropical and humid environment where they evolved. Let’s check out the fundamentals behind a vigorous and strong vegetative growth phase for cannabis plants.
Depending on the size of the plant, support may be required. Some sativa strains grow like normal-sized trees during the vegetative stage. Even though one doesn’t have spatial limitations outdoors, the branches may snap under their own weight if the plants are too tall. Tying the branches may be a smart move. One could also use topping techniques, which creates more bushy and stable plants.
The Vegetative Phase Of Cannabis Cultivation The vegetative phase in cannabis plants’ life cycle is vital as plants use it to prepare for an optimal flowering period. When caring for your plants
