How to Grow Weed Indoors: A Beginner’s Guide

The most challenging obstacle you’ll encounter when growing weed indoors for the first time is to get started. To begin, you must first select an appropriate growing location and acquire the necessary growing equipment. Then you would purchase marijuana seeds or plants and devote a significant amount of time to monitoring and sustaining your harvest.

Before you begin, you must ensure that you are operating within the bounds of your country’s law. Many jurisdictions in the United States currently prohibit marijuana cultivation. As a result, check to see if home cultivation is permitted where you reside before continuing. Keep reading our comprehensive guide if your state permits growing weed indoors.

Step 1: Choose the Ideal Cannabis Growing Environment

It is not necessary to have room to grow or cultivate your plants. A tiny container, cabinet, or dedicated space in an empty room is a standard grow space for a first-time grower. Even an empty corner of your house will suffice if you’re short on room. Here are a few pointers to get you started.

1 – Start with a small plot and adjust as required.

By “small,” we mean that you are growing no more than a maximum of five to six plants. You may start with just a plant or two at a time. Indoor marijuana cultivation comes with an unavoidable learning curve. As a result, you’re likely to make several mistakes. Fewer plants will die if you have fewer plants in the first place.

The majority of the time, even experienced weed growers make mistakes and have accidental mishaps. As a result, it’s likely to have a failed harvest on the first try.

It won’t take much time for you to get an understanding of everything and start growing those lovely flowering weed plants. But, of course, you’ll have to find space at this point while your pot grows. By the time of harvesting, your plants may have doubled or tripled in size.

2 – One of the most important factors while growing is to keep the space clean.

Ensure that your growing area is fully sanitized and tidy. Pests and toxins present an unavoidable danger. Pathogens, infectious bacteria, and mold thrive in a cluttered setting. Making a weekly cleaning regimen and sticking to it is a smart idea. Wiping up the places nearby your plants with a damp microfiber cloth would suffice.

Being naturally bio accumulators, cannabis plants have the ability to suck everything within their setting, whether it’s in the soil, water, or air. To keep possible toxins away, make sure the environment around the plants is safe.

3 – Make the grow area as light-tight as possible.

The process of growing necessitates the use of light. Most of the time, your plants are exposed to direct sunlight. However, not many beginner growers know that darkness is just as vital for growing yieldable plants.

Marijuana plants, like other living organisms, need some time to “rest.” If any light seeps into your growing room while it is supposed to be dark, the (bud-bearing) females enter their survival mode and grow male flowers, destroying the chances of a good yield.

4 – Indoor Growing Success Needs the Following Features

You must choose a convenient location away from any “unwanted guests.” Doing this keeps your plants protected from intruders, be it humans or animals. It also allows you to keep track of them frequently.

Concerns over humidity and temperature will still be a problem. Choose a location from where the outside fresh air can’t enter.

The importance of convenience is equal to that of everything else. As a result, ensure your location is safe and available at all times.

Step 2: Choose Your Cannabis Grow Lights (and Use Them)

The type of lighting you have in your grow area has a big impact on your plants’ growth. We recommend allocating a significant portion of the expenditure to lighting. It’ll eventually pay off, particularly if you’re looking to grow cannabis long-term.

LED Grow Lights

LED lights are the preferred choice for most pot growers if they have a good budget. For growing weed indoors, these are extremely effective light fixtures. They produce almost no heat and consume hardly any energy. LEDs often produce wavelengths from all sections of the light spectrum, resulting in higher yields and higher-quality crops.

The disadvantage is that LED lights cost almost ten times more than a good HID system! However, if you are a serious grower and have the cash to spare, LEDs should be seriously considered. To prevent ‘scam’ LEDs on the internet, do your research thoroughly.

Grow Lights With Induction

Indoor growers can find induction lamps to be an unusual alternative. Many companies, though, have reportedly adopted them for use in the marijuana business. Induction lights can be a good deal in terms of expense and performance.

These grow lights are more effective than fluorescent lights while still being less expensive than HID and LED systems.

High-Intensity Discharge Grow Lights

HID lighting is perhaps the most widely used light if you wish to grow weed in a DIY style. When it comes to ease of service, performance, and expense, they usually provide the best value.

The biggest disadvantage is that HID lights need various accessories to function properly. As a result, based on the amount you’re able to spend, the total expense will easily escalate.

Based on the growth level, there are two major forms of HID lamps/bulbs preferred by most people. During the vegetative phase, MH lighting is the most efficient. Whereas during the flowering period, HPS lighting is the favored alternative. If you just have the budget for one, go for HPS because they provide better light in terms of watts.

HID lights generate significant heat. As a result, you’ll need to buy a hood and a ballast for your lights. Temperature control is almost impossible without this. To filter out heat energy and retain an average air temperature, connect your ventilation system to the hood.

Fluorescent Lighting

Fluorescent lighting is usually less expensive and simpler to utilise than other alternatives. They are an ideal option for someone who does not want to work for an extended period of time. They may not necessitate the use of an active ventilation device. Fluorescent lamps are inefficient compared to the other choices. They are, however, definitely the best choice for first-time growers with just a few plants.

Step 3: Healthy Cannabis Plants Need Plenty of Fresh Air

Ensure the airflow is constant in your grow room. You can comfortably accomplish this based on your room’s size. What you’ll need is an exhaust fan and a portable fan.

The exhaust fan will remove the moist, humid air as warm air increases. The portable fan delivers a steady stream of cooler, CO2-rich fresh air. This method ensures that the plants are supplied with fresh air regularly. It also aids in maintaining an ideal temperature.

The majority of marijuana strains prefer temperatures between 65-80 degrees Fahrenheit. Set the ambient temperature between 50-70 degrees when the room is dark. Indica strains favor the colder part of the temperature spectrum.

Step 4: Create a monitoring and control system for the growing process.

The next thing is to set up a self-monitoring device to keep track of everything. We know you can’t be in your grow room for the whole day! You’ll have to buy a timer and a cooling system that can be adjusted. You can use the latter to automatically turn on your exhaust fan as the temperature rises above a certain point. As a consequence, the humidity level and temperature spectrum are reasonably constant; thus, resources and money are saved.

Buying a 24-hour timer will be the most important thing. When the cannabis plants enter the vegetative phase, the light must be turned on for at least 16 hours a day. Your plants would need an equal 12 hours of light and darkness until they have reached the flowering phase.

We also suggest purchasing a pH meter to track the consistency of your soil and water daily. The suggested pH for growing on soil varies between 6 or 7. For a hydroponics system, the pH should be around 5.5 to 6.5.

Step 5: Choose a Marijuana Growing Medium

You have two suitable alternatives for growing weed indoors: on soil or hydroponically. If it is your first time growing weed indoors, the soil is usually advised. It is less expensive, easier to use, and more accommodating than a sophisticated hydroponic system.

Growing in the Soil vs. Growing Hydroponically

The soil will cost you less, is easier to work with, and has a larger error margin. However, you must choose the soil wisely since the consistency will differ greatly. When you incorporate nutrients into general soil regularly, it works. Soil that is pre-fertilized soil, on the other hand, is a safer choice since it saves you from any guesswork. This kind of soil demands very little upkeep.

What you need are good soil and a nutrient-rich, well-balanced growing mix. Mycorrhizae and bat guano microbes, along with additional compost nutrients, are ideal products.

An automatic hydroponic system can assist you in achieving faster growth and better yields. Unfortunately, this is only possible if it is handled properly. You’ll be wasting a lot of resources if you don’t!

A hydroponic system uses osmosis to supply the required nutrients and minerals to the plants submerged in water. Some experts tend to do it by hand, picking their nutrients and minerals by hand. This, though, requires a lot of time and practice.

If you choose hydroponics over conventional soil, there are some excellent kits available that are simple to use and fail-safe.

The drawback of growing hydroponically is that you will have to spend a minimum of ten times more than what you will pay for high-quality soil.

Step 6: Decide on a Cannabis-Growing Container

If you opt for growing your weed in soil pots, you won’t have to buy another container. A 3-gallon container or any ordinary bucket may also be used to cultivate plants. Marijuana plants, on the other hand, dislike being submerged in water. Perforate the container’s bottom to allow water to flow when desired.

There are several fantastic pre-filled soil pots on the market that have been developed specifically for improved airflow. When determining where to start growing your marijuana plants, keep these factors into account.

Step 7: Give Your Plants All The Nutrients They Need

Getting the correct nutrients for your plants is potentially just second in importance to ventilation. To grow top-quality weed, proper nutrient collection and implementation are essential. Though cannabis is tough, growing it in less-than-ideal conditions reduces production and potency.

You need to provide your weed plants with the seven most important macronutrients, whether you’re cultivating hydroponically or in an organic soil mix. The following is a list of nutrients in no special order:

  • Potassium (P)
  • Phosphorus (Ph)
  • Calcium (Ca)
  • Magnesium (Mg)
  • Nitrogen (N)
  • Iron (Fe)
  • Copper (Cu)

Finally, certain strains need more calcium as compared to others to yield strong, durable nugs. Explore the strain you’re growing. This procedure allows you to have a better understanding of the types of nutrients it likes.

Step 8: Water is a must-have for cannabis plants!

The belief among novice weed growers is that the more you water your weed, the healthier.

Though this is valid to some degree, overwatering does exist. Your cannabis plants can die if you overwater them!

A few apparent factors decide the level of watering and the quantity you have. These factors include the growth period of the weed as well as its size. For instance, marijuana plants do not take nearly as much water during their early growth phase compared to mature flowering plants.

Ensure that your growth medium has pre-drilled holes in it to allow water to flow. When watering, don’t saturate the soil; instead, moisten it.

Step 9: Carefully Trim The Cannabis Leaves!

The last step is to harvest your weed. Many first-time growers believe that the nugs appear on the branches independently. They will then pluck them out, ground them up, and smoke them. It’s a tad more tricky!

A multitude of leaves is mixed in the nugs on a good, “pre-harvested” vine. You’ll have to cut the leaves with scissors to get the nugs. After getting used to it, you will find the process to be fun rather than boring.

Final Thoughts on Indoor Weed Growing

Growing weed indoors is a delightful experience. It’s one we’d suggest to every cannabis enthusiast who is interested in all facets of the herb. By growing weed indoors, you gain a great deal of knowledge regarding weed in general. The majority of growers agree that each harvest teaches them something different.

There is no denying that there is a learning curve. You’re bound to have a few errors. But believe us when we claim that you will find it to be worth all the hard work in the end.
