Editor’s note: This is part seven of a seven-part series on what readers should know about adult-use, or recreational, cannabis in Connecticut.
A s we mentioned in Day 1, growing cannabis plants at home won’t be an option until July 2023 — unless you’re a medical patient who was allowed to get started in October 2021. Either way, the rules are the same.
Let’s take a look, courtesy of Hearst Connecticut state government reporter Julia Bergman.
Medical patients ages 18 and older may grow up to three mature and three immature cannabis plants at home, with a cap of 12 total plants per household. The same rules will apply to all Connecticut adults 21 and older come July 1, 2023.
Plants must be grown indoors at your primary residence and can’t be visible from the street or anywhere people under age 21 can access them.
Where do I get seeds?
You can buy seeds online, but perhaps the simplest way is to get them from someone who is already growing cannabis plants. Under Connecticut’s law, you’re allowed to give away cannabis as a gift.
Seed prices vary depending on the strain and quantity. A quick look online showed prices ranging from $25 to $1,000 depending on the strain.
Which kind of seeds should I get?
Traditional cannabis plants are either male, which produce seed pods, or female, which produce flowers that can be harvested.
If you’re buying regular seeds, you have about a 50/50 chance of them being male or female.
Autoflowering feminized cannabis seeds are often recommended for first-time growers. These seeds produce plants that flower on their own and don’t require any changes in lighting.
Autoflowers also take less time to grow and are compact, which makes them ideal for growing indoors in small spaces.
The downside? They produce fewer flowers and lower THC levels, Connecticut hemp farmer and Wepa Farms CEO/founder Luis Vega said.
What’s the difference between a mature and immature plant?
Mature plants are in the flowering state, which is when they produce THC, the psychoactive ingredient. Immature plants are in the vegetative state — the period of growth between germination and flowering.

What about the lighting?
Plants should get 18 hours of light when they’re in their vegetative state and 12 hours of light when they’re flowering.
Joseph Raymond, founder and president of New England Craft Cannabis Alliance, recommended purchasing LED grow lights, which are more expensive “but definitely worth it,” as bad lighting can ruin the process.
What other equipment do I need?
Raymond and Vega recommend purchasing a specialized tent to keep a controlled environment. Raymond also suggested supplemental CO2.
You’ll need a fan for air circulation. Raymond prefers a peat moss-based soil, or a coconut coir-based soil for hydroponic growing, in which specialized watering systems replace their natural counterparts, sun and rain.
Raymond said growers should water plants one to three days per week. Overwatering and not providing the soil with enough nutrients such as nitrogen and phosphate fertilizers are among the most common mistakes people make, said Kebra Smith-Bolden, a registered nurse and the CEO of Connecticut’s CannaHealth.
How long does cannabis take to grow?
Indoor growing times vary but, on average, from seed to harvest it usually takes about three to four months — but this largely depends on lighting and the equipment used.
Growing autoflowering plants takes 8 to 10 weeks on average.
How much cannabis will I be able to harvest from my plants?
That depends on many factors, including the strain and how long you let your plant grow. Raymond and Vega said on average people should expect to get 2 to 4 ounces of pot per plant.

How Long Does It Take To Grow Weed?
How long does it take to grow weed is a very commonly asked question. Usually it takes about 3-4 months to grow the average cannabis plant – but with the right tools and strategy, you can grow the weed plant you want in as little as 8 weeks. Let’s take a look at the question of how long does it take to grow weed and the time needed for each step.
How Long Does it Take to Grow Weed – Growing Timeline
The timeline below lays out a seven-stage process of a typical grow schedule. If you’ve been searching online for “how long does it take to grow weed?” you’ve likely run into a range of time periods. Generally, a marijuana plant can take 14 to 32 weeks to grow, which translates into about four to eight months to grow. This is for growing a marijuana plant from seed.
The length of time it takes to grow a weed plant can be broken down into multiple phases from seed to harvest:
- Getting your equipment (1 day to 2 weeks)
- Getting your clones or seeds (1 day to 4 weeks) (12 hours to 8 days)
- Seedling phase (1 to 4 weeks)
- Vegetative phase (2 weeks to 6 months)
- Flowering phase (6 weeks to 3 months)
- Harvesting phase (1 to 3 days)
Step 1: Getting your weed growing equipment = 1 day to 2 weeks
If you know what you are looking for then this could happen quickly. We will help you with this later on as we set up the grow-rooms and do some grows with different styles and grow mediums.
Step 2: Getting your clones or seeds = 1 day to 4 weeks
Getting clones (cuttings from healthy mother plants) is easy to do in areas that allow cannabis cultivation. But in states or countries where it is illegal to grow, obtaining healthy clones can be a challenge. Seeds, on the other hand, can be ordered on the internet and generally take 2 to 4 weeks before they arrive by mail.
Step 3: Germinate The Seeds = 12 hours to 8 days
If starting with clones this can be skipped. The average time to germinate is 2 or 3 days. Make sure to check your seeds every day because seedlings can sprout in as little as one day. You’ll know your seed has germinated when your seed has popped and displays a tap root formation.
Check out our guide on the best method to germinate marijuana seeds using paper towels and water.
Step 4: Seedling Phase = 1 week to 4 weeks
Once again, can be avoided if using clones and not seeds. As your cotyledons begin to take shape, so will your cannabis leaves in a single leaflet form. Generally, growers can give their seedling a light amount of nutrients after the third set of leaves begins to appear.
Step 5: Vegetative Phase = 2 weeks to 6 Months!
Yes, that is correct. This stage in the plants life has a huge fluctuation in how long it needs to take. You, as the grower, hold all the power and get to choose how long this phase is. Once you change the light cycle that the plant receives to 12 hours of light, and 12 hours of darkness per day, the plants will switch to the next phase, which is flowering.
If you want to, you can switch the lights to 12/12 right away and force your plants to flower! The sooner you change to 12/12, the faster your plants will flower, and the sooner you can move on to the next crop. But, keep in mind, the less amount of time you keep your plants in the vegetative phase, meaning getting at least 18 hours of light per day, the smaller your plants will be, and the less marijuana you will have to use.
If you are concerned with how big your plants will grow, maybe because you only have a small space to grow in, you can grow cannabis that only grows only a few inches tall, and you could even grow it the entire time in a little plastic cup if you wanted to!
Keep in mind that buds do not form for at least 2 to 3 weeks in the vegetative phase when beginning with seeds. Most growers allow their plants to stay in the vegetative stage from a few weeks to a few months so they get big enough and will end up with a sizable harvest. Bigger plants produce more buds!
But, many growers choose instead to grow small plants and to harvest more often with smaller yields each time. We recommend at least 3 weeks or more in the vegetative stage with at least 18+ hours of light each day for optimal yields. Even 24 hours of light per day is sometimes better, with certain strains.
The more light, the more buds!
Keep in mind that cannabis plants usually double in size from vegetative phase to when they are done flowering. This means it’s sometimes best to change to 12 hours of light and 12 hours of darkness once the plants are one-half the size that you feel your grow room has adequate space for.
During the vegetative phase, you can use a number of cultivation training techniques such as super cropping, crimping, topping, tying, bending, sea of green (SOG), screen of green (SCROG), and trellising to alter the growth, direction, height, and quality of your crop.
Autoflowering strains, however, have a different vegetative time period than regular feminized seedlings. Autoflowering strains will have at least two to three weeks of vegetative growth before they automatically start showing any bud formations regardless of photoperiod.
Step 6: Flowering Phase = 6 weeks to 3 months
In nature, cannabis plants start to flower in the fall months, when they are receiving less light. The decrease in light signifies to the plants they are nearing the end of their life cycle and its time to begin flowering.
How Long Does It Take for Marijuana Seeds to Sprout?
Growing your own weed takes time and energy, but when you obtain your first harvest, you’ll know how rewarding it is. Growing weed isn’t hard science, especially if you have previous experience with growing plants, so if you learn the basics the rest will quickly follow.
This article focuses on the germination process of growing weed, and the most common germination methods, as well as some tips for success. Whether you’ve chosen indica or sativa, or regular or autoflowering seeds, germination is crucial to the plant’s growth process and the start of its lifecycle, so keep on reading for some helpful tips and information.
How Do Weed Seeds Work?
Weed seeds are the small oval-shaped fruits of the cannabis plant. They’re covered in a subtle membrane, albumen, which keeps the center of the seed healthy until it’s time for germination. At the center of the seed you can find the embryo from which the new plant grows from. This embryo contains the plant’s genetic code and is the place from where the taproot starts forming.
Similar to other plant seeds, cannabis seeds are the fruit of the pollinated flowers of female weed plants that don’t contain any psychoactive effects. However, they can be consumed as food since they’re the source of a lot of vitamins, minerals, and beneficial proteins.
Pros and Cons of Using Cannabis Seeds
When it comes to cannabis cultivation, germinating cannabis seeds is one of the methods you can choose. This method of cultivation has a lot of benefits, but also a few downsides.
Some of the benefits of cultivating marijuana seeds include:
- The presence of the taproot from the germinating seeds provides more support in the initial growth stages of the cannabis plant.
- You don’t inherit pests from the mother plant.
- As a result of the expansion of the cannabis market, you can choose from a huge variety of high-quality seeds from a lot of seed banks all over the world.
- Seeds can be stored for a long time without going bad and still germinate.
On the other hand, the downsides when using cannabis seeds include:
- Having to wait until the plant reaches the flowering stage in order to differentiate whether it’s a male or a female plant.
- Seeds can take a while before they pop (germinate).
- Germinating seeds is harder for newbie growers since it requires more skill.
Cannabis Seeds vs. Clones
Compared to cannabis seeds, cannabis clones are an example of asexual propagation, or replicating from a single parent. The cutting is taken from a stable mother plant and is grown into a genetically stable ang genetically identical plant under the right conditions. The benefits of using clones for weed cultivation include:
- Ensuring that the gender of the new plant is female.
- Knowing which traits your plant will have.
- The cultivation process is several weeks faster compared to a seed that needs to sprout.
- The clone is less delicate than the seed is at the beginning.
- Growing clones is easier since you only need to “plug and play”, so beginners will find this process easier.
How Are Marijuana Seeds Grown?
You can grow marijuana seeds both inside and outside, depending on the conditions, space, and resources available. Generally, growing marijuana indoors requires a dedicated space and equipment, like fans, grow lights, and heating pads. This method is more private and gives you better control, but at the same time, it’s more expensive and demanding. Growing outdoors is the easiest and cheapest way to grow, provided that there’s enough sunlight – at least 6 hours of light daily. The downside is that you’ll be limited to the growing season even though outdoor marijuana yields a lot more weed because the plants grow bigger. If growing outdoors isn’t an option for you, or you want to grow all year long, you can always invest in some quality lights.
Marijuana plants usually start out as a seed, but some growers use clones as well. Basically, a clone is a cut-off from a plant that’s used to grow another plant. Growing weed from seeds is a little more convenient, especially if it’s your first time growing weed, plus, seeds give a stronger plant.
Before the seeds turn into a beautiful marijuana plant, they need to be prepped for transplanting, or in other words, they need to germinate.
What Is Seed Germination?
Seed germination is the process when a plant starts sprouting from seed and continues growing from there. During the germination process, the food reserves present within the seed are converted into sugars that the plant uses to increase in size, causing its root to start breaking through the shell. This is the first sign that they have germinated.
Once emerged, the root is crucial to the plant’s survival as it provides the necessary nutrients from the environment. After this process, the germinated seeds are ready to be planted in the growing medium of your choice.
The simplest and most common one is soil, but in recent years, hydroponics are also becoming popular – Rockwool cubes and coco, especially. The downside of these growing mediums is that you need to be well-versed in pH levels and maintain the optimal pH and nutritional status of your plant at all times.
Germinating Your Cannabis Seeds
There are three most common germination methods.
Soaking Cannabis Seeds in a Glass of Water
This is the simplest method and it’s especially helpful for older seeds as it helps to wake them up, or even seeds with hard shells. The process is pretty straightforward: you need to fill the glass with lukewarm water and soak the seeds. At first, they should float in the water, and sink to the bottom after a few hours have passed. If some of the seeds don’t sink, you can try pushing them gently to the bottom.
After you’ve soaked the seeds, put the cup of water in a dark and warm place, and leave them for 36 hours at most. The seeds that have started sprouting will have a tiny white root sticking out. If, after 36 hours some seeds have no signs of sprouting, we recommend you put them in a warm and moist place to encourage the germination process.
The Paper Towel Method
This method is probably the most popular one among weed growers. You’ll need a kitchen paper towel and two plates. We recommend you use a nonporous paper towel (usually the cheaper brands), as this will retain moisture for longer. Here’s a brief step-by-step guide:
- Moisten two sheets of paper towel and put them on one of the plates;
- Carefully place the cannabis seeds over the wet paper towels;
- Fold the damp paper towels over so that the seeds are well covered;
- Cover with the other plate to create a dark space, but make sure to leave some room for oxygen, i.e. don’t align the plates perfectly;
- Check on the seeds often, about every 5-8 hours, and if you notice that the paper towels have dried even a little, spray them immediately to maintain the moisture.
If all goes well, the seeds should take 24 hours to start sprouting, but if they haven’t (this might happen with old seeds), leave them for up to 72 hours and check on them constantly so they don’t run out of moisture. With this method, you’ll need to be patient, as some seeds just need a little more time.
Germinating Seeds in Potting Soil
You can also mimic nature’s way by germinating marijuana seeds directly in a growing medium. This method allows the seeds to sprout in potting soil and continue living there without the need for transplanting. The upside of this method is that the marijuana seedlings will get used to its home environment from the beginning and it’ll be easier to thrive.
To do this, you need to put the seed about ½ inch deep in moist (not wet) soil. Put some soil over the hole to cover it and press lightly. The seed will germinate under the surface and, in about 4 to 10 days, it should slowly spring to the surface.
So, How Long Until They Germinate?
As you can see, the germination of cannabis seeds depends entirely on the type of seed and the chosen method. A rule of thumb is that it takes approximately 24-48 hours for the seeds to start sprouting, however, there can be some exceptions to this rule, of course. Just remember that moisture and warmth are very important and remember to check on the seeds often.
What Do Marijuana Seeds Need for the Germination Process?
Seeds need the ideal environment to break through and start germinating. Seeing as this process is one of the most important steps in growing your marijuana plants, here’s what you need for achieving the best germination rates:
- High moisture levels – your cannabis seeds need a lot of moisture (about 80%) to help them expand, however, be careful not to add too much water, and always make sure you use clean tap water;
- Warm temperatures – the marijuana plant is a warm-season plant that thrives in springtime, so ideally, you should put the cannabis seeds in a warm place and maintain the temperature between 68°-72° Fahrenheit or 20°-22° Celsius;
- Minimal interference – you’ll need to avoid touching the germinating seeds while they’re going through the process because the taproots (cotyledons) are very fragile and prone to breaking. If you must handle them, wash your hands first, or use clean gloves.
Remember that when the seeds are healthy, they will respond well to this basic setup and you won’t need to do or add anything extra to help your cannabis plants grow.
A Few Don’ts for Successful Marijuana Seed Germination
Even though seed germination is a relatively straightforward process, knowing a thing or two beforehand can help you avoid making mistakes and make the most of your seeds.
- Don’t let the germination container dry out. Moisture is very important to kickstart the process, but maintaining the moisture is even more important. Whichever method you choose to germinate the seeds, we recommend you check up on them daily to ensure that there is enough moisture. This especially applies when you use a heat source to achieve warmth as it may cause the water to evaporate faster than normal.
- Don’t leave the seeds to germinate for too long. This means that you shouldn’t wait for the taproots to grow very large, as they will be very delicate and make the subsequent transplant more difficult for you. Plus, leaving them for too long means that they’ll be exposed to air which puts them in danger of oxidation and further damage. Therefore, make sure they’re about ½ -1 inch long at most.
- Don’t plant the seeds too shallow or deep. This is a common mistake that weed growers make, but it’s easy to be avoided. When you plant the seeds too deep, the seedling won’t get enough air and it may suffocate deep beneath the surface. On the other hand, if you sow the seeds too close to the surface, it will result in weak and underdeveloped stems. Your best bet is to plant the seeds at about ½ inch depth.
- Don’t germinate seeds in the same container. Cannabis seeds need plenty of room to grow, so if you plant several in the same pot, they will compete for light, nutrients, and space, resulting in little branching and weaker roots. This will, in turn, affect the quality of your plant. So, unless the container is big enough, you should give the seeds enough room to thrive.
So, How Long Does It Take for Marijuana Seeds to Sprout?
Seed germination is an essential step in the process of growing your own weed. The average time for marijuana seeds to germinate mostly depends on the type of seeds and the germination method. However, the usual time frame is between 24-48 hours. The most important elements that support seed germination together are warmth, moisture, and peace.
