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.
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.
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.
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.
There is another section on plant problems but a good hint to know at this stage is that it is common to mistake too many nutrients or PH misadjustment for nutrient deficiency. Always carefully check PH before adjusting nutrients to fix a problem and if adding nutrients doesn’t seem to be fixing your ‘deficiency’ try flushing the system instead. Unlike the drooping leaves that result from under or over watering yellowing and necrosis from nutrient problems generally don’t recover but they stop getting worse and new growth will be green and healthy.
With the screen of green, or SCROG technique, a screen of wire such as chicken wire is held up as a horizontal plane above the plants. The plants are nudged through the screen to create a uniform canopy so that all light is utilized by growth. Generally anything below the canopy is trimmed off.
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.
Sea of a green is a technique whereby you grow a far greater number of smaller plants rather than a small number of large plants. Usually clones are used for uniform growth characteristics and each plant is trimmed so that only the main stalk grows.
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.

Removing leaves in the vegetative phase will slow down the growth process of your plant. Only remove leaves from a healthy plant. It will let you control the shape and growth speed of your plant. Use this technique to create a smaller plant that exposes its buds to the grow lights.
These steps create a lot less stress for your marijuana plants because they are only tied down or bended. There is no cutting involved. Through bending, you can make your plant grow a horizontal rows of buds. Bend over branches that are taller than the rest. You can try tying them down or use weights. Super cropping is essentially a technique where you bend your plant until the bent point is slightly damaged.
Growing indoor gives you the opportunity to build just the right conditions for your plants. The growth phase is the heart and soul of your plant’s health – just follow our ideas and tips from this article. We have covered light, air, and water in a hydroponic system before and I recommend you to check out these resources for best practices for your cannabis plant.
For today’s piece about vegging cannabis, we will assume that you have planted your seeds or clones already. After the process of propagation, small and fresh baby weed plants have now started to grow. You might have used seed starters, a special growth medium or a plastic dome to help them grow initially. Now you have brand new marijuana plants to take care of. It is time to find their spot in your grow room and start improving their health, strength, and shape.
One of our favorite options for the best pots for growing weed are the 5 Gallon Fabric Aeration Pots from iPower, which you can usually find on Amazon in a 5-pack or 10-pack for under $20.
You’ll want to change up your nutrient mix for each stage of growing from seedlings/clones, to vegging, to flowering. Your plants have different needs as they go through these stages and you need to feed them differently to keep them healthy.
Fimming is similar to topping. It’s called FIM for “F*ck I Missed” because you pinch off
The size of your plants will be determined by their roots. The amount of roots will be determined by the pots or net pots you are using. Give the roots room to grow and the plant will grow as well. If you plan to grow in soil, your plants will need to be watered frequently, especially if growing in a small container. In addition to more root space, larger containers will afford you a bit more leniency here as well. Lastly, breathable fabric pots (rather than plastic) will help ensure your plants get the aeration they need.
Keep in mind how big you need your plants to grow. When using the same space, having a lot of plants will mean less time until the room is filled in buds. A smaller number of plants means the need for them to grow bigger and taller until the space is completely filled.
