Cannabis flowers can be used for evaporation, smoking, or processing into other entertainment foods after being dried and pickled.

Before you start, you need to understand whether the local laws support planting and ownership. If you live in the United States, then the following website can help you

Why Indoor Cannabis Grow

  • Save money and time-growing by yourself is more economical than buying
  • Health reasons-using cannabis to treat various diseases
  • Supply-stable supply, never drying up
  • High-quality cannabis-can produce any cannabis you want
  • Safety-no need to deal with drug dealers or other channels to obtain marijuana
  • Fun-planting will give you happiness and a sense of accomplishment

How long does it take from start to harvest

After you start planting, it takes at least three months for most types of hemp to be harvested (some varieties take less time, some varieties take longer). After harvesting, hemp buds need about a week to dry. The drying time depends on temperature and humidity. Most growers usually marinate the buds for more than two weeks to get a better taste. In other words, it takes 4 months from planting to smoking.

Growth schedule

1 week – dry

2 weeks – pickling

Total: 4 months

 Indoor Cannabis Grow

Basic knowledge of growing cannabis

Cannabis plants are similar to other plants and require various conditions to grow. In order to thrive, hemp needs to meet the following points

  1. Light (the intensity and spectrum of light have a great influence on yield)
  2. Air (where air flow is needed)
  3. Growth medium (not necessarily soil, but soil is the most accessible and economical choice)
  4. Temperature (the most suitable temperature for marijuana growth is between 70-85 degrees)
  5. Nutrients
  6. PH (maintain the correct pH value, the pH value of the soil is 6-7, the pH value of the hydroponic solution should be 5.5-6.5)

These are the six conditions necessary for marijuana growth, whether it is indoor or outdoor cultivation, you need to ensure that these six conditions are met. You will be rewarded for harvest! A common problem for new growers is that they tend to skip certain key steps, such as maintaining the correct pH. Maybe you will be lucky to grow cannabis successfully, but the probability of the plant’s death, in the end, will be much higher.

Light

Outdoor planting

When marijuana plants are grown outdoors, they usually need at least 8 hours of light a day. If a marijuana plant wants to grow quickly in a short time, it will need a lot of light energy to power this growth.

Many indoor growers like to grow cannabis plants next to windows instead of using artificial light sources, which will save electricity bills. In fact, they are wrong. Usually, the light from the window is not enough, the cannabis plant will not produce flowers and buds at all during the flowering stage, and you will get nothing.

Indoor planting

Nowadays, growers rely on growth lights to provide light for plants when they grow indoors, and they are usually used in conjunction with timers to realize plant growth lights automation. There are many types and sizes of plant growth lights, how to choose the right growth lights, you need to consider the planting area and budget decision.

Air

Your cannabis plant needs air! Cannabis plants breathe carbon dioxide like humans breathe oxygen. As for why carbon dioxide is needed, look at the equation of photosynthesis and you will get the answer. They need a continuous supply of carbon dioxide to thrive.

In addition to exhaust fans, you can also install some small fans on the top of the tent to blow air from above to below the plants, which will provide fresh air and carbon dioxide for your plants.

Growth medium

Cannabis growers can choose many media. There are many methods for you to choose from, such as soil, cocoa, hydroponics, etc. How to choose a suitable medium for cannabis?

The growth medium is where the root system of the cannabis plant develops. Most novice growers will choose the soil, which is easy to obtain and free, but you can also choose another. There is no optimal medium. Each medium has its advantages and disadvantages. You can choose according to your actual situation and planting experience.

For details, please refer to What Is The Best Growing Medium For Cannabis?

Temperature

Pay attention to the temperature not too cold or too hot. Cannabis likes room temperature or a slightly warmer temperature. 70-85°F (20-30°C) is great. Keeping the right temperature can keep your plants growing fast.

Nutrition

Getting cannabis-friendly nutrients is important if you plan to use nutrients during your growth. Some types of nutrients just don’t contain the right “stuff” for the best plant growth and bud development.

Cannabis nutrients are easy to use – just follow the directions, like a recipe.

Unless you have composted your own cannabis super soil, you will most likely want to supplement your cannabis grow with nutrients to make sure plants are getting everything they need.

If you’re growing in soil, you will want to get nutrients made for soil.

If you are growing in any medium besides soil, you will need to get hydroponic nutrients (nutrients specially formulated for hydroponic growing). Some popular soilless mixes for growing cannabis have special nutrients, for example, there are many nutrient systems made specifically for growing cannabis in coco coir.

PH value

In order for your plants to absorb nutrients through the roots, they need the correct pH of the root environment. The easiest way to maintain a proper pH is to test and adjust the pH of the water before watering the plants.

What pH are you looking for when growing cannabis?

Soil: 6.0 – 7.0 pH

Hydroponics: 5.5 – 6.5 pH

Settings and selection

  • Choose your planting space
  • Choose your medium
  • Choose grow lights
  • Nutrients (if needed)

Choose your planting space

The first step in indoor cannabis cultivation is undoubtedly the need to establish a growth space for cannabis. There are many forms to choose from, including planting tents, planting rooms, etc. You can choose the most suitable method according to the actual situation. If you don’t have much experience, you can choose a ready-made, easy-to-implement method. A prefabricated planting room or planting tent will be your best choice.
The planting room can be located in the garage, bedroom, wardrobe, or even any corner of the house.

Planting tent vs planting room vs greenhouse
Planting a tent: You may be wondering what is the fastest and easiest solution. Planting a tent is the simplest and most common solution. The tent has a variety of sizes and styles to choose from. You can create a controllable growth environment for plants without complicated operations such as drilling.
Growth space: The growth space can be a bedroom, a garage, etc. This requires certain experience and skills and is more like a DIY solution. You can buy fans, reflective materials, and hydroponic systems to set up the growth space. There is space, so the cost can be less.
Outdoor planting: There is no doubt that outdoor planting is the most economical option. It only requires a greenhouse and does not need to purchase too much equipment, but the plants may be plagued by unpredictable climate.

Pros and Cons – Growing marijuana indoors vs. Outdoors

Choose your medium

What is the best medium for cannabis cultivation? Understand the advantages and disadvantages of soil, coco, rock wool, and hydroponic cultivation so that you can better choose the medium.

Cannabis growers can choose from the cultivation medium and technology to get the harvest. Soil, coco, hydroponic plant
Which one to choose? What are the advantages and disadvantages of each technology? How should you choose? Since the choice of medium is a very important step in growing hemp, we will provide a guide to make it easier for novice growers.

What Is The Best Growing Medium For Cannabis?

Choose grow lights

Now almost all indoor growers are using plant growth lights, but now there are many types of growth lights, usually divided into HID plant growth lights, CFL and fluorescent lights, LED plant lights, next, we will analyze each kind of light The advantages and disadvantages so that you can choose the right growing lamp.

Most common HID bulbs:

  • MH – Metal Halide Grow Lights– used for the vegetative stage, makes white/blue light
  • HPS – High Pressure Sodium Grow Lights– used for the flowering stage, makes yellow light
  • (New) Ceramic Metal Halide(Various names for this technology include CMH grow lights, Light Emitting Ceramic, LEC grow lights and LECs)

For the comparison between HID lights and LED lights, please refer to the Comparison of HID and LED grow lights

Advantages of HID

Cheap: MH/HPS/LEC is one of the cheaper grow lights, especially when your budget is not enough, it will be a good choice for you.
Easy to use: just hang on the top of the tent and start working
A large number of tutorials: HID lights have been used for planting for a long time, you don’t need to worry that you will not use them. Almost all HID grow lights are used in the same way, and there are already a lot of related tutorials on the Internet.

Disadvantages of HID

Heat: HID lamps generate a lot of heat when they are used, and a fan is usually required to discharge the excess heat.
Height: Small MH/HPS settings require at least 5 feet (1.5 meters) in height, larger settings require 6 or 7 feet (~2 meters) in height

CFL and other fluorescent plant grow lights

The two most common types of cannabis fluorescent lamps:
CFLs
T5 panel

Pros of CFLs & Fluorescent Grow Lights

Cheap setup: CFL and T5 can be started with a small budget.

Low height needed – CFLs are sold as individual light bulbs and T5s are sold as several long tubes in a panel, but each needs only a few feet of height for successful growing

Options for low heat, low electricity – Just a few CFLs or a single T5 doesn’t produce much heat or use much electricity

Cons of CFLs & Fluorescent Grow Lights

The low yield-the yield of these grow lights tends to be small unless you use a lot
Heat-Each CFL bulb generates a little heat (especially large bulbs), and growers who use many CFL or fluorescent tubes need to expel additional heat (usually by using a fan to dissipate the heat outside).
The least efficient plant light-when considering the light production (and output) used for electricity, the energy-saving lamp is the least efficient plant light. T5s are made for gardening and do better, but they are still not as good as other grow lights.
Routine maintenance-it can be difficult to place the CFL near the plant, and the lighting needs to be constantly adjusted during the planting process

LED plant light

Advantages of LED

Customized spectrum-As one of the latest types of cannabis plant growth lights, LED plant growth lights are different from any other products that grow cannabis on the market. In the past few years, prices have dropped and quality has improved. LED production is increasing every year, and there are now many reliable LED models that have been proven to be used for cannabis cultivation
Invisible-Small LED spotlights or panels are very suitable for invisible growth because they can fit into many sizes of spaces, and they usually have a built-in radiator to disperse heat into the growing space (instead of direct heat beams to the plants )
Low heat and low battery options-the small LED panel does not generate too much heat or consume power

Disadvantages of LED

Expensive setup-when considering the price of how much light will be produced, LED grow lights are the most expensive cannabis grow lights
Heat —— Each LED panel generates a little heat (especially high-power models), growers who use a large number of LEDs need to discharge the extra heat like any other grow light (usually by using a fan to dissipate the heat to the outdoors)
The use of LED requires the skill-each type of LED plant growth light needs to be used in a different way. The size of the LED chip, the reflector of each bulb, and other differences in each model make it difficult to make any generalizations about how to use a particular LED panel. You cannot use your LED panel like your friend unless it is the exact same model from the same manufacturer. Even if your LED panels look the same, they may need to be used in different ways to avoid harming your plants. It is very important to ask the manufacturer how far away the LED panel should be from the top of the plant, and how much space the panel can cover at that height.
