How long does it take to Grow Cannabis – Full Guide 2020

How long time takes to grow cannabis

How long it takes to grow marijuana is one question many growers ask, especially those growing the crop for the primary time. Though it’s going to seem like a clear-cut question that contains a ready answer, it is not. This is often because the longer it takes to grow marijuana depends on the spread of things and, therefore, the strain of the marijuana plant. The mode of growth also determines how long it’ll take to grow your weed from seedlings to harvest. The life cycle of the expansion starts from germination to growth stage and eventually to the flowering stage before you get to the harvesting phase.

Each of these phases is very important if you would like to attain quality product and optimum development, and this might take anything from three to four months on the average, but there are other marijuana planting methods and tools which will have you ever harvesting the crop in about eight weeks. One of the most effective and fastest methods of growing cannabis is indoors because it takes lesser time than growing it outdoors. In this article, we’ll attempt to guide you through the marijuana growth timeline for indoor grow tent and grow room growers so as to answer the question; HOW LONG DOES IT TAKE TO GROW MARIJUANA?

Readying you equipment for planting

Getting your equipment ready for the seedlings may take anything between one to two weeks. However, if you’re a seasoned grower, then you recognize what exactly you would like, and this era might be shorter for you. New time growers may, however, take up to two weeks to organize everything. Preparation means setting up the grow rooms, determining what methods you’re using like HYDROPONIC GROWING, POTTING SOIL or DWC system, and other mediums like LED GROW LIGHTS, REFLECTIVE MATERIALS, and much more.

Seed or clone collection

For people who stay in states that legalize marijuana cultivation, then this stage is going to be too easy for them as they will get clones from healthy cannabis mother plants easily. People who stay in states that don’t legalize cannabis cultivation may have a harder time getting clones, but the great thing is that they will get the seed online. Delivery of the seeds takes anything from two to four weeks.

Seed germination

The average time it takes to germinate the seeds is anything from two to three days, but if you’ve got clones, then this stage isn’t necessary.


The seedling stage takes anything from one week to four weeks, but as long as you using sees rather than clones. If you’re using clones, then this stage is again unnecessary.

Growth and vegetative stage

This is one of the most important stages, and it determines the length the crop will take to mature depending on how you handle it. You hold all the ability during this stage, and therefore the slightest mistake can cause inferiority yield or none at all. During this stage, you’ve got to create sure that the plants get enough light, enough nutrients, enough water, and enough oxygen.

In this phase, you’ll force the plants to grow much faster by giving them more light hours or allow them to move to the nest stage gradually by giving them 12 hours of light and 12 hours of darkness. Though giving the crops more light hours so as to hasten their vegetative stage allows us to start out another cycle of growth sooner than later, you’ll end up with smaller plants that will not offer you much yield. Marijuana buds take two to three weeks to make buds if you started with seeds. For optimum yield, the advice would be 18 hours of light for a minimum of three weeks.

The flowering period

The flowering of the crop takes anything from six weeks to three months, depending on the strain. Marijuana starts to flower when the sunshine hours reduce. For this phase, you’ll, therefore, give your plants twelve hours of uninterrupted lighting and another twelve of uninterrupted darkness. During this stage, you also increase NUTRIENTS with higher levels of Potassium and Phosphorous and reduce Nitrogen. In about seven to ten days during this stage, cannabis revels their sex, which is two white hair sprouting of the nodes being female and, therefore, the rest being male. Some marijuana strains can take up to sixteen weeks during this stage.


Harvesting of the crop depends on what proportion you’ve got in your grow room, but this could take anything between one day and three days.
