The first aspect to decide on before starting your marijuana crop is the place. Outdoor cultivation helps you save money thanks to the weather.
Meanwhile, many planters tend to choose indoor options because of their advantages. Indoor crops enable you to decide every condition for your project’s best result.
This article will give you comprehensive guidance on how to grow weed indoors. We will share with you tips about setting the materials and planning the space.
Let’s read on to discover!
Advantages Of Growing Weed Indoors
People enjoy growing their cannabis plants indoors because they can control all the conditions in their crops. Besides, there are still some benefits for indoor cultivation.
You need more materials than cultivating outdoors. Moreover, you will most likely have to spend even more money on supplies to power the equipment.
However, you surely have complete control over your growing environment and what you feed your plant. It allows you to fine-tune your installation to produce some top-notch weed.
Check out this article. If you don’t know indoor vs outdoor weed: Which is better?
You will not depend on the sun and the weather conditions as you are with outdoor cultivation. You’ll be offering the plants everything they need to develop.
Indoor growth can also enable you to manage the number of nutrients and water that your plants get. Other factors like humidity or temperature are controllable too.
You may let your plants develop to their full potential. You also need to manage when they blossom and harvest. And, you can start another crop right now or anytime you like.
You may plant at any time in the year, even straight through the summer or winter. You’ll always receive consistent outcomes.
Security and privacy
Although you live in legal states, you may want to keep your crop discrete. Indoor cultivation allows you to plant quietly behind a closed door.
Setup Growing Weed Indoor
Indoor cultivation requires the gardeners to do everything. For the best harvest, you need to work on these tasks. Don’t miss anything in the checklist below or you’ll ruin your crop.
Find A Place To Grow Cannabis Indoors
Growers have tons of options for growing space. Below are some of the finest ideas.
Basements include a hidden safe haven for marijuana cultivation because they are underground. They generally don’t have any windows, so there aren’t any light escapes. Basements are also often big, providing more space for a huge crop.
You’ll also notice that the temperature in the basement is quite consistent throughout the year.
The majority of basements feature air tubes that allow trapped air to escape. Keep an eye out for the end of the shaft.
Regulating the temperature in a garage is simple. Even under the severe weather conditions in the summer and winter, this place still stays cool.
In most cases, garages are not as effectively insulated like the other parts of your home. Cover any holes or drafts that could allow the odor of your plant to move out. Black off any windows if you aren’t utilizing a grow tent. If not hidden, the appearance of bright LEDs will attract curiosity.
One of the best sites to cultivate marijuana is in an attic. There is no reason for your guest to enter that room. Most attics are completely dark and won’t let any light in.
The attic may not have any electrical outlets. For added stealth and convenience, you might want to consider adding some plugs. Running some fans to maintain the room temperature is also a nice idea.
- Grow box
By creating a grow box, you may cultivate marijuana almost anywhere in your home. The tools for constructing the box are available around your house, such as PVC pipe, a fan, and a light. You can also feel free to adjust its size to fit any corner in your house.
- Tiny place
If the options above are impossible, don’t worry! Even a small place can be useful. It would be surprising that you can grow your plant in buckets or cupboards.
- Grow room
Constructing a grow room is the best choice if you have enough time, space, and budget. You can build a robust, closed-off chamber specialized to weed from wood, PVC, and other materials. After that, equip the grow room with lighting, ventilation, and other features before starting your cultivation.
There are three main types of medium to choose from when it comes to cannabis cultivation:
Soil is the most conventional and accommodating medium for planting cannabis indoors. This method is also an excellent choice for first-time planters. To assist the transformation of organic material into nutrients for a plant to absorb, good marijuana soil depends on a robust community of soil bacteria and mycorrhizae.
Natural soil comes in four varieties: Sandy, Silty, Loamy, and Clay. That most soils consist of varying ratios.
- Soilless Potting Mix
A soilless potting mix is a medium that comprises a combination of substrate without soil. Inorganic and organic ingredients, such as perlite and coco coir, are popular in soilless mixtures. For growing marijuana in containers, soilless mixtures are a great choice.
If you’re working with natural soil, you can improve any type of soil by adding amendments includes: Coco Coir, Perlite, Clay Pebbles, Vermiculite, Worm Castings, Bat Guano, Peat Moss.
The major growth medium in hydroponics is soilless surfaces or just water. Water-soluble fertilizers move straight to the roots of plants. Because the mixture includes no soil, the farmer has a lot more influence on the nutrient consumption of their crops.
This increased measure of control may lead to larger, richer harvests for skilled gardeners, since their crops can absorb more nutrients.
During their vegetative and blooming periods, weed plants require various degrees of light. While growing indoors, you will have more influence on the light system.
When crops are in the vegetative phase, they require 18 hours of light every day. When they are blooming, they require 12 hours.
When the weed starts to grow flowers, the light quantity needs to decrease, from 18 hours to 12 hours.
You’ll have to keep your interior grow area light-tight because the number of photons a plant obtains is so crucial. During the gloomy periods, light leaks might mislead your plants, causing them to grow male blooms or return to a different phase.
Different lights may emit various hues. There are some popular types of lights for indoor cultivation as follows:
High-intensity discharge is the abbreviation for high-intensity discharge. These lights are the international standard, with a wide range of applications due to their intensity, effectiveness, and cost.
They are somewhat more pricey than fluorescent or incandescent or fixtures. Yet, they generate significantly more brightness per unit of power required.
They are not as effective as LED lights, but they are considerably less expensive.
The two most common types of HID light used in farming are:
- Metal halide emits white light. This light works well during the vegetative stage.
- High-pressure sodium produces red and orange light. This is the best choice for the flowering phase.
The HID illumination system includes a ballast for each bulb. Some ballasts can work with only one kind of light, although many current versions can handle both.
If you have to choose between the said lights, go for the high-pressure sodium. It produces more light. Magnetic ballasts appear to be less expensive than digital ones, but they run harder.
Digital lights are a preferable option in general, although they are more pricey. You should avoid heap digital options. This is because they can result in electromagnetic interference.
Because HID bulbs release lots of heat, you may need the air cooler to put your lamps in. If you plan your crops in an open space with enough ventilation, you can skip the air cooler.
This necessitates the construction of exhaust fans. They will raise your initial costs but allow temperature management in your house much easier.
LED engineering has been famous for a long time. It keeps on improving inefficiency. The biggest limitation of LED grow lights is their high price. A high-quality fixture can cost up to ten times as much as an equivalent HID system.
However, the positives are various. LEDs can last considerably longer and consume far less power.
Moreover, it can produce significantly less heat. The finest designs include a larger spectrum of light, leading to higher yields and superior productivity.
- Fluorescent lights
Producers choose fluorescent lights for their marijuana crops with small sizes. This is because these lights are easier to set up in one box.
They also don’t need a cooling system as they don’t create nearly as much heat as HID fixtures.
The biggest disadvantage is that these lights are less effective. It only delivers around 20 to 30% less than the consumed power.
Space is also an issue. A single 600 watt from the high-pressure sodium light would take roughly 15 four-foot-long to offer the same brightness.
Weed plants prefer the fresh air. When there is a wind, they develop the fastest. It also helps to keep mold at bay.
A fan is the best method to provide the necessary airflow for your plants. To enhance airflow, you may also trim bigger leaves.
You may also want to exhaust the tent’s heated air and replenish it with cool air. At the absolute least, you’ll require an exhaust fan.
Carbon Dioxide Supplementation
Most growers have discovered that a Carbon Dioxide concentration of 1,200 to 2,000 PPM will greatly boost plant development when you are creating a high-quality lighting system in your garden. Furthermore, your plants can withstand a greater average temperature, about 85 to 90°F, while utilizing CO2.
Keep in mind that if the CO2 levels go too high for the quantity of light or heat produced in the garden, your crop will become a disaster.
Because CO2 is dense and sinks to the soil, it should preferably fall from above your garden. Utilizing fans can assist circulate CO2 throughout space, allowing more plants to obtain it. CO2 should only appear when the lights are working. Your plant photosynthesizes when it’s dark outside.
Controlling the temperature is vital for every crop. There are some factors you need to follow for the best growing conditions:
- Lights: Different types of light will emit different heat levels. Often, LEDs tend to release less heat than other light sources. You can adjust the intensity of the light to modify the temperature.
- Air flow: Air can affect the temperature. You can use fans to reduce the hot air and bring more cool air to your garden. Fans can slo exchange the air via a canopy to cool the leaves.
- Air conditioners: If you want to speed up the cooling process, utilize the AC. It works well when the weather is too hot and there are not enough fans.
- Heaters: On winder days, a heater can help balance the temperature. This assistance means more when the lights stop working and there is no heat from it.
The amount of moisture in the air is the humidity. Here are some tips on how to keep it under control in your cannabis grow space:
- Dehumidifiers: Dehueys can reduce moisture in the air while simultaneously raising the temperature. You can use this tool if the humidity is higher than necessary.
- Airflow: Controlling the air flow enables you to raise or decrease the moisture in the grow space. The simplest way to lower the humidity is to let the door open.
- Humidifiers: This tool can add more water vapor in the grow space. Growers use it when the weather is dry and the moisture level needs to rise.
- Water: If you don’t have a humidifier, spray your plants with water to add additional moisture.
Dehumidifiers And Air Conditioner
If the growing space is overly humid, a dehumidifier, often called “dehuey,” may be necessary. Remember that while dehueys lower humidity, they usually boost temperature. When installing a dehumidifier, you need to use extra fans or an air conditioner.
Maintaining the ideal environment for your crops may be a complex balancing act involving numerous types of equipment as well as a lot of power. The tools needed make indoor marijuana cultivation more pricey than outside cultivation.
Automation – Timer
You should definitely get a timer for the light system. The vegetative or blooming stage of a crop depends on the quantity of light it gets. As a result, it’s critical to provide it with a constant quantity of light every day. In this scenario, a timer might be useful. It’s a nice choice to double-check the timer every week to make sure it’s still functioning.
You may also control the timer to control the fan although a thermometer is preferable. Remember to set the tool to a certain temperature. When the weather is too hot, the fans will run. They will stop when the weather gets cold.
Most dehumidifiers and air conditioners come with built-in thermostats. If yours doesn’t, you’ll need to get one.
Environmental controls enable gardeners who have very little budget to invest in their crop to simplify the process. If you’re going to be away from the plant for a long time, these gadgets are important.
To maintain the growing condition, it would be best to install a controller in the fans, humidifiers, and dehumidifiers. Then, depending on your preferred environment conditions, establish thresholds for each device to turn on and off.
There are some pieces of equipment that include a mobile control feature. You can regulate the equipment via phone or computer easily.
Start Growing Cannabis Indoors
Once you have prepared everything, it’s time to start your crop. The first thing to do is to select the strains. After that, your stain will go through four stages of its life cycle. In each stage, there are some requirements to ensure the development of your crop. Let’s follow the instructions.
Marijuana plants include 4 key phases during their development from seed to harvest:
Germination (3-10 days):
Seedling (2-3 weeks) : 70-85°F; ~70% humidity
Vegetative (3-16 weeks) : 70-85°F; 40-60% humidity
Flowering (8-11 weeks): 65-80°F; 40-50% humidity
Check out the details on 4 key stages of marijuana growth for more info.
Choosing The Right Strains and Best Places To Buy Cannabis Seeds
There are two ways to get marijuana seeds: via seed banks and in person.
You should begin with fantastic genes if you want to decrease the risk. It also helps ensure that you constantly generate incredible-quality marijuana.
The way your marijuana plants grow relates a lot to the genetics they got started with, just like animals. Each marijuana plant combines the characteristics of its parents.
Because genetics has such a great influence on your achievements, knowing about the genetics of the species you’re treating is essential.
Sativa, Indica, and Hybrid are the three primary kinds of marijuana strains.
Almost every marijuana strain you meet will be a hybrid. Some strains are more Indica-leaning, while others are Sativa-leaning.
Indica strains provide a stronger body high and develop bushier and shorter.
Sativa strains can produce a mental high. Sativa plants tend to grow larger, demand greater light, and take longer to grow than Indica plants. Hence, they may need specific plant treatment to be suitable for indoor cultivation.
Indicas have thicker and rounder leaves. Meanwhile, Sativa’s leaves appear to be thinner and finger-like.
Growing marijuana plants from hybrid strains are generally the easiest. They will develop to have the finest features of both Indica and Sativa.
Auto-flowering strains are also popular these days. They begin blooming independent of the light routine. These are generally well-known strains that can develop to have the auto-flowering characteristic.
You may offer these strains up to 18 light hours every day for the whole growth. And, you can harvest your crop for approximately 3 months. Auto-flowering strains seldom grow taller than two feet due to their short growth cycle.
When choosing a marijuana strain to grow, pay special attention to the light needs, grow times, and other factors. This is to ensure that it is a suitable fit for your garden space.
Germinating Your Cannabis Seeds
A starting cube is the most convenient method to cultivate marijuana seeds. Simply place the seed, keep it warm and wet in the cube.
The roots and sprouts will develop after a few days. Then, you should place the complete plugin in your seedling container. You won’t be worried about treating the fragile seeds once you grow them this way.
You may even germinate the seeds in the same pot that your small seedlings will be in. It may be a plastic cup as well.
Put the marijuana seeds around 1/2 or 1″ deep to obtain this. The soil ought to be damp but not wringing wet.
Keep this condition throughout the germination stage by watering it anytime it starts to dry up. You’ll also want the seeds to stay warm. A heating pad or a light can offer heat.
During germination, try to maintain the temperature at 73°F and the moisture around 70%. Provide them 18 hours of light and 6 dark hours every day.
The marijuana plant has finally hit the vegetative stage when it develops its first pair of normal leaves.
The Vegetative Stage Cannabis Plants
When your marijuana plant turns to the vegetative stage, things start to get interesting. The plants are developing quickly. However, they have yet to form any flowers or buds.
The benefit of planting marijuana indoors is that you have complete control over the environment. It allows you to create the optimum conditions for the maximum harvests.
Lighting should be the first and most essential thing you can manage. You need to keep the grow lights on for about 18 hours each day when vegging.
Some planters want to provide 24 hours of light. Yet, we recommend opting for an 18-hour on and 6-hour off timetable.
You can also set the humidity and temperature of the air. Keep the growth space from 70 to 85°F. The humidity between 40 to 60% is the best for this stage.
No worries if you don’t have any humidity sensor. Your marijuana plants will thrive as long as they are neither cold nor burnt. Maintaining the proper conditions simply means quicker and greater growth.
Feed your plants on a regular basis. Provide them extra water if the upper part of the soil seems dry. Water the plants until you will the base of the pot with about 20% excess runoff water.
Ensure you don’t overwater your plants. Always wait until the topsoil layer is completely dry before watering.
Your marijuana plants will absorb a good quantity of nutrients if you utilize nutrient-rich soil. You’ll have to supply more in the future by applying them to water your plants.
Your plants should grow plump and short with a few peaks. Each peak obtains the same brightness and grows the same big bud as a result.
You can handle this in various ways. We prefer to tie down the young main branch and twist it downward. This is to force it to expand horizontally. Then a slew of additional branches will sprout from that too.
Your marijuana plants outgrow their pots. If you still want them to develop, you’ll need to change the pot.
If you’re filling a new container with fresh soil, wait for a while. Your plants need to use all the nutrients in the old soil before you stop adding any new watering to them.
At the end of the stage, you may want to do something new. You can use the female plants for other crops. They are clones now.
The length of time between vegging and blooming is contingent on how big you like your plants to become. An average strain would double in size during the flowering stage. So, you should remove it from the vegging stage when it is approximately half the size.
The Flowering Stage Weed Plants
Simply control the brightness your plants receive each day to urge them to bloom. Your plants will start to blossom if you adjust the lightning current to 12 hours off and 12 hours on.
The plants also require much more light throughout the blooming stage. Make sure you provide it. The finest grow lights are the powerful LED system.
Plants may get more sensitive to moisture during this stage. Remember to maintain it low to avoid mold.
Provide a temperature of 65 to 80°F and a humidity of 40 to 50% throughout the early stages of flowering. In the end, change it to 40 and 50%.
You’ll be able to identify the gender of the plants one or two weeks after that. You won’t need to worry if you have utilized feminized seeds because they’ll be all female.
After eliminating all the male plants, you should still take care of the female. They can totally turn into hermaphrodites, which generally happens when they’re under pressure. If this occurs, you can remove only the area of the plant that has started.
Another essential job during the flowering stage is to ensure that all of your buds obtain enough light. If you notice any bud in the shade, bring it into the light. It can develop and produce more.
Supplemental light is the most effective approach to achieve this. If your main fixture does not offer a lot of red light, you may want to consider adding additional lighting. In such a situation, a few tiny all-red LEDs might be quite effective in increasing yields.
Marijuana plants require a lot of nutrients during the first month of flowering. Their requirement will become less after that.
It’s a great idea to cleanse your plants in the final two weeks before harvesting. This implies that you should offer them only water, free of nutrition. This avoids the nutrients from leaving a taste on the weed.
Flushing and Harvesting Weed Plants
You can use two methods to know if you can harvest your crop now or then.
Looking at the tiny white hairs that come out of your bloom is a fast method. They are the pistils. They will begin to bend inward and get dark with time.
The second approach is more precise. However, it necessitates the use of magnification of some sort. The digital microscope is ideal for examining trichomes. This is because it provides more accurate images.
Observe the trichomes with magnification. They are the crystals that build up on your buds.
You’re only focused on the ones having the ball on top. They resemble mushrooms.
Also, check the color of the trichomes carefully. Trichomes may be clear and milky white. In this case, you will receive a more intense experience. The THC levels are high too.
You’ve come to the end when the trichomes have darkened. They provide more CBN, resulting in a more calming high.
Above is the step-by-step instruction and explanation on how to grow weed indoors. Every component is critical. They contribute to the quality of your crop.
