First time marijuana grower?

Who can grow their own?
With passage of Proposition 64, anyone in California over 21 years old can have up to six plants. If you’re a medical marijuana patient with a doctor’s recommendation, you can have as many as you and your doctor decide you need.

That said, all non-commercial cultivation for recreational use (called “adult use” in California) and medical use is subject to local regulations. Many cities and counties require permits even for personal use and many ban outdoor growing entirely, requiring you to grow indoors under lights. Check your locality’s rules.

While we can sell plants to you and you can legally drive them home, you may be subject to restrictions on how and where you grow them.

Where can I grow my plants?
The best place is outdoors in sunshine and fresh air, where plants are happiest. Plant them in the spring or summer and harvest in the fall. However, if you don’t have access to garden space or your local jurisdiction doesn’t allow outdoor cannabis growing, you can grow them indoors under high-powered “grow” lights. Check with your local city or county officials to see if there are specific limits on where you can grow.

Growing any plants indoors under artificial lighting, but especially cannabis, requires some research, skill and practice. There are many books and websites dedicated to it.

We recommend outdoor growing in the normal gardening season, so most of what follows is somewhat specific to outdoor cannabis gardening.

First, some basics about cannabis plants.
Cannabis is a “genus”, a taxonomic unit used by biologists to classify living organisms, that contains several species: Cannabis indica, Cannabis sativa and Cannabis ruderalis. These interbreed freely, resulting in “hybrid” species that contain features of both parent species. (Note that Cannabis nomenclature is changing. Stay tuned.)

Cannabis has been the subject of such intensive breeding that there are virtually no “pure” sativa or indica strains. Virtually all are hybridized.

Boys and girls
Cannabis is also “dioecious”, which means male and female flowers are borne on separate plants. This may seem weird, but it is quite common in the plant world. Pistachios, date palms, stinging nettles and Gingko trees all have male and female flowers on separate plants. Just as only female pistachio trees produce nuts, only female cannabis plants produce the useful flower clusters commonly called “buds”. Male flowers are tiny and fall off once they’ve bloomed and shed their pollen.

The process of identifying which plants are male and which are female is known as “sexing”. It is an important part of cannabis cultivation that takes an experienced eye. At the nursery, we take the guesswork out of it and guarantee that our plants are all female.

While you can grow both male and female plants together, you will end up with low-quality “bud” that is packed full of seeds. By excluding the males, the female flowers will never be pollinated, allowing the clusters to grow bigger and more potent. Male plants, once identified at the nursery, are composted.

Seed-grown or clone?
Plant Humboldt is one of the very few cannabis nurseries to offer female plants grown from seed. This is the original Humboldt grow-your-own tradition. Many cannabis farmers—old-timers and first-timers, medical users and commercial growers—still prefer seed-grown starts.

Others prefer starting from rooted cuttings, known in the industry as “clones”. Clone plants start as small branches cut from a “mother plant” and rooted in trays indoors in a controlled climate under artificial lights.

There are advantages and disadvantages to both seed-grown and clone-grown starts. Seed-grown plants tend to be more vigorous, but can sometimes show variation in their production, and they need to be sexed properly to exclude males (something we take care of at the nursery). Clones, being genetically identical to the mother plant, will produce bud with consistent look, smell and potency, but are often less vigorous plants and have specific light requirements that can be tricky for beginning growers (see below). Clones are only cut from known female plants, so all clones are female from the start.

Along with seed-grown plants, we sell clones in 4” pots that are well-rooted and acclimated to natural light and air, so they are ready to plant in your garden straight from the nursery.

Night and Day
Cannabis is an annual plant and has two seasonal growth phases: vegetative and flowering. During spring and summer (“veg” phase), the plant puts on extensive leaf and stem growth, often in massive amounts.

As the days get shorter and nights get longer in late summer (August in the Northern Hemisphere), the plants are triggered into flowering phase (“budding”). If you’re an outdoor grower, you will typically plant in the spring and harvest in the fall, whether you’re starting your plants from seed or clone.

But, with clones there’s a catch. Clones are cut off of a mother plant that is kept indoors under artificial light for 18 hours or more per day, so the mother plant and the little cutting “think” they’re living in an endless summer of long days and therefore remain in vegetative phase. If you put that rooted cutting outside in the spring under natural daylight, when the days are short, it thinks it’s fall and time to flower. A seedling, on the other hand, will wait till the light naturally fades again in the fall to go into flower.

At the nursery, we add a few hours of supplemental light with low-wattage LEDs in order to trick the clones into thinking it’s endless summer and therefore keep them in vegetative phase. After about June 1st, you can plant a clone in your garden and it will grow normally, with no extra light needed. Before June 1st, you will need to add supplemental lighting for a few hours each evening (or early morning) or the plant will go immediately into flower and you’ll end up with a tiny plant with one little bud on it. Supplemental lighting can be as little as a single low-wattage bulb on a timer next to the plant. You don’t need expensive horticultural grow lights because all you’re doing is tricking the plant a little.

Cultivation Basics
Cannabis is as easy to grow in your garden as a tomato plant, but there are some rules of thumb that will dramatically improve your yield and quality.

Soil
We recommend all first time growers use commercial potting soil, not native garden soil. Master gardeners can grow cannabis successfully in natural dirt, but beginners will have much better results with bagged soil.

Container
The bigger the roots, the bigger the plant. You can dig a large hole and fill it with commercial potting soil or use a plastic pot or fabric grow-bag above ground. The bigger, the better. Many Humboldt commercial cannabis farmers use 200 gallon (or bigger) fabric grow bags, but these are expensive and require a lot of expensive soil to fill. For a personal-use amount of finished marijuana, a 20-gallon pot will be manageable and can be put on a patio or deck. In the ground, dig a hole at least 30” across and 18” deep and fill it with commercial potting soil.

Fertilizer
You can spend $100 on a bottle of plant fertilizer with a fancy label, but there’s no need to. Any organic fertilizer will do. Some commercial potting mixes, especially those formulated for cannabis, have significant amounts of plant nutrients included. In vegetative phase, cannabis likes more nitrogen (marketed as “grow” formula fertilizers). Once your plants switch to flowering phase they need lower nitrogen but more phosphorus and potassium (“bloom” formula).

Spacing
When provided proper care and large root space, outdoor, seed-grown plants can easily grow to be eight feet tall and equally broad. In some cases they can grow twice that size, all in one short season. Even for a beginning gardener, a well-cared for cannabis plant in a 20-gallon pot can still get four feet tall by equally wide, so plan your space accordingly.

Trellising/staking
Modern cannabis strains have been bred for heavy flower (“bud”) production, often to the point where the branches will break under the weight if not supported. As the branches grow out, gently tying them to thin bamboo stakes with plant tie wire (available at garden stores) will keep them from breaking off later during flowering phase.

Pest Control
Cannabis is relatively pest-free, but there are a few that can ruin your entire crop, particularly mites and molds. Detailed pest control descriptions are available online, in books and through cannabis-centered grow shops. Below is a quick overview of what to look for. We recommend getting a 100x pocket microscope and checking your plants regularly, especially the undersides of the leaves where mites live. These are available at most grow shops for about $20.

Mites
Spider mites and russet mites can destroy your plants and buds. Spider mites leave white “stippling” spots where they suck the juice from the leaves. Large infestations will build up webs on the plants. (Learn to distinguish from the webs of actual spiders, which are beneficial!) Spider mites are barely visible to the naked eye, but easy to identify with a pocket microscope. There are many available organic treatments.

Russet mites are microscopic, but visible with a 100x pocket microscope. The reason they are so feared among growers is that by the time damage becomes visible, the crop is often irrecoverable. That is why it’s important to do preventative pest control and maintain constant vigilance. Don’t wait till your plants look sick! Russet mites look like tiny milky colored maggots with four legs in front. They are much harder to spot at first and, unlike spider mites, are literally microscopic and can only be seen with a 100x pocket microscope. Growers are still struggling with organic control methods. Natural insecticides based on essential oils, neem and yeast enzymes all seem to work to varying degrees. Check with your local grow shop. We recommend doing routine preventative control even if you don’t see russet mites with your microscope. The good news is that anything you do to control russets will also control spider mites, thrips, fungus gnats and most other cannabis pests.

Detailed pest control is beyond the scope of this page, but you’ll need a small hand-pump sprayer and some organic pesticide. Any good grow shop can advise you. You don’t need to spend a ton of money to do basic preventative control. At the nursery, we use various organic pest control sprays preventatively about twice/week, but most home growers won’t need near that often of a spray schedule. If you are diligent with your microscope inspections, you may not need to do much at all if you don’t see any mites.

Fungi
Powdery mildew, also known as “powder mold” or “PM”, is a fungus that grows as a white powdery coating on the leaves and buds. In small amounts it will not hurt the plant, but you don’t want to be smoking it if it gets on the flowers near harvest. It is easy to control with dilute hydrogen peroxide, potassium bicarbonate, bacterial anti-fungal solutions (e.g. Actinovate, Serenade) and many other off-the-shelf and DIY concoctions. Look online, in books or ask at a grow shop for detailed information.

Brown/gray mold, also called “bud mold” or “stem mold” is a systemic fungus that rots buds from the inside out. The best way to prevent it is to keep the plants from getting rained on during flowering phase and to provide extensive dry airflow. Once mold is identified in a bud, remove and discard the infested part and harvest the adjacent bud to limit the spread.

Harvest and storage
The rule of thumb is that when most of the pistils (commonly known as “hairs” for their appearance) on the flower clusters (“buds”) have turned from white to brown, it is time to harvest. If possible, have an experienced friend take a look and give you harvest advice, or check online.

To harvest, cut the branches, remove all the large leaves by hand or with a scissors and hang the branches in a cool, dry place with plenty of airflow but minimal heat. There is an art to proper curing and it takes some experience to get it right. The main mistakes are drying too fast with too much heat, which causes the buds to crumble, and drying too slowly, which can cause mold. A cool, dry (not damp and moldy!) basement with a small fan blowing on a string full of branches is ideal unless you want to invest in specialized climate control equipment like commercial growers do.

The proper dryness is when the buds are dry, but not crispy to the touch. A good rule of thumb is to bend the stems below the flowers. If the stems snap but don’t break clean through, the flowers are probably about the right dryness. If the stems merely bend, let the cannabis dry some more. If the stems snap clean through into separate pieces, the flowers are probably too dry. If needed, they can be placed in a slightly more humid environment briefly to rehydrate so they don’t crumble when handled.

Once the proper dryness is reached, clip the buds off the stems and store in a cool, dry place. Glass jars in a closet are perfect. Be sure to check the moisture levels regularly to avoid mold.

Bag Seed vs Hype Seed: Is it worth it to buy cannabis seeds?

You found some cannabis seeds! Yay! Should you grow them? Or should you buy cannabis seeds online at an online seed bank like Seedsman or Seed Supreme? What about on social media or even at a dispensary? How important are the marijuana seeds you start with?

Sometimes you get lucky with plants grown from found seeds. This bag seed produce excellent quality buds (though weirdly, the starting weed was not purple at all)

Unpredictability is the biggest downside to seeds you find in your weed. I have seen incredible grow results with “bag seed” or seeds growers find in their weed, like the plant pictured above. The higher the quality of the starting weed, the greater the chance the seeds will produce good buds, too. That being said, bag seed can have problems including bud quality, poor germination rates, the potential for hermies, and unpredictable growth patterns.

Poor Quality Seeds = Confidence Killer!

Using random cannabis seeds (even from dank bud) can produce unpredictable results. Plants may grow wild or produce small airy buds with low potency, even if the original weed was dense and potent.

Pros of Using “Bag Seed” (seeds you find in your weed)

  • Seeds are free (buying cannabis seeds can get expensive!)
  • Easy (you already have seeds in hand)
  • May produce good bud if it came from good buds

Cons of Using Bag Seed

  • Bud quality may not be as good as the weed it came in
  • Potential for poor germination rates since seeds likely weren’t stored properly
  • Unpredictable growth patterns – for example, plants may get tall or take a long time for buds to mature before harvest
  • Potential for male plants (male plants don’t produce buds while feminized seeds produce all-female, all bud-producing plants)
  • Hermies are common (hermie plants produce seedy buds, which is often how seeds got in your bud in the first place)

Today we’ll investigate those potential issues so you can make an informed decision. Let’s do a quick deep dive!

1.) Bud Quality

Genetics makes an enormous difference to your results. For example, the following two strains were grown in the same space with the same grow medium, nutrients, and grow light, yet the results were completely different.

These strains were grown in identical conditions. The green plant produced almost double the yields. The purple plant produced far less yields but the buds were denser, smoother to smoke, and almost twice as potent (14% THC vs 26% THC). When you buy seeds, you can choose what you like instead of the results being left to luck.

2.) Germination Rates

Germination is the process of getting your cannabis seeds to sprout and turn into seedlings. Typically, seeds are removed from buds and stored in a cool dry place to keep them fresh and viable. However, if the seeds have been sitting in your buds and the buds, it’s possible they weren’t stored in optimal conditions. That can cause you to have low or poor germination rates, even if you’re using a proven germination method.

“Found” seeds may have poor germination rates, for example, they may start germinating and “stall out” like this one did. It seemed healthy but never grew past this point.

3.) Growth Patterns

Using random seeds (even from dank bud) can produce unpredictable results. Plants may grow wild or produce small airy buds with low potency, even if the original weed was dense and potent. This is because the genetics weren’t stabilized to produce consistent results.

Bag seeds may grow in unexpected ways!

4.) Male Plants

Cannabis plants can be male or female, and with regular seeds, about half of plants are male. Female plants produce buds, but male plants only produce non-smokable pollen sacs. That means most growers want to throw away male plants so they don’t take up room in the grow space. On top of that, if the pollen sacs open up and release pollen on any nearby buds, those buds will get pollinated and end up with seeds in them. If you found seeds in your buds, there’s a strong chance that pollen got on the buds while they were forming.

Why am I explaining this in an article about bag seeds? Because when you’re growing from bag seed, there’s a strong chance that about half of your seeds will end up being male plants. This is important because male plants don’t produce buds and male flowers make your buds seedy. You need to be on the lookout for them.

Unless growing with feminized seeds, typically about half of all seeds will grow into male plants like this one. Male flowers are pollen sacs, which look like bunches of grapes.

After a few weeks, male flowers open up and pollen gets everywhere.

If any pollen gets on your buds, it will cause seeds to grow. This is one way that seeds can get in your buds.

Whenever using found seeds, you should determine the sex of young plants as soon as possible. This lets you toss all the male plants before they start making pollen and seeding your buds.

5.) Hermies (Hermaphrodite Plants)

The other main way seeds end up in your buds is from a hermaphrodite plant, or “hermie”. A hermaphrodite is a plant that produces both male and female flowers (both buds and pollen). The pollen from the male flowers pollinate buds and cause seeds to grow just like if a male plant released pollen.

Why is this important? Hermie seeds often produce hermaphrodite plants, which means your buds will likely have seeds in them.

Notice how these plants are producing both female flowers (buds) and male flowers (the pollen sacs are circled). Remove this plant immediately because once the pollen sacs open up they will seed all your buds.

Another type of hermie produces small yellow growths often called bananas (the “banana” would normally be found inside a pollen sac but on some plants it will grow exposed on the bud). Bananas start releasing pollen immediately and also cause seedy buds.

The best way to ensure all your plants end up being female is to start with feminized cannabis seeds from a trustworthy breeder. (Do feminized seeds make hermies?)

If you plan to use bag seed, just remember that there is a chance the resulting plants will be hermies. Keep an eye out for pollen sacs and bananas.

Should I buy seeds on social media like Instagram or Facebook?

Many growers get seeds from other people on social media sites like Instagram or Facebook. Can these seeds be trusted?

You need to be wary of any informal source of seeds, especially from people you don’t know and trust. There are many scammers taking advantage of growers by sending poor quality cannabis seeds or even no seeds. Try to find at least two legitimate people who have ordered successfully from the same source before you send any money. It sounds like a pain but it can save you a lot of time and money.

Additionally, there are many scammers that pretend to be legitimate companies. For example, several people on Instagram have copied our account (profile and posts) then messaged people to sell seeds as if they were us. Then they seed seeds of unknown quality or don’t send anything at all. If you’ve been following our actual Instagram account, you may not notice the seller is @growweedeasy_ instead of @growweedeasy.

Double and triple-check your source before ordering seeds through social media. Don’t throw money down the drain.

Or even better, just order seeds from a proven seed source that offers high-quality seeds and a plethora of excellent strains. If you’re lucky enough to live need a cannabis dispensary, you can sometimes find quality seeds there.

Be on the lookout for scams when buying seeds on social media. Consider a proven source of seeds.

Conclusion: Get Hype Seed if you Can!

Use found cannabis seeds at your own risk. You may get decent or even great results, but you may be disappointed, which can be a real confidence killer especially for new growers. There’s nothing more frustrating than doing everything right only to get bad results after 4 months of growing. I highly recommend buying at least a few seeds from a trustworthy breeder to ensure you are happy with the weed you grow at the end.

One awesome strain that won’t break the bank (3 seeds for $30) is Critical Purple Kush. I’ve grown it in different setups and buds produce smooth and relaxing effects. A crowd favorite.

Critical Purple Kush buds are sparkly with great yields, plant growth, and bud quality.

New Weed Bag Seed Forget About It

All the plants started flowering under 24 hour light.

All the plants grew small buds and the weed sucked.

I’ve been traveling in my 2001 Chevy Express High Top Conversion van with Ricky, my 4 year old American Bulldog/Staffordshire Terrier mix, for the past year which has been really great. We’ve done over 15,000 miles and visited 23 states. I’m stuck home for the winter because I ran out of money.

What’s not so great? I haven’t been able to grow any weed and have been buying it in Colorado. The price hasn’t been too bad, $85.00 per ounce out the door at the Green Dragon weed store, but still, I can grow it for around $30.00 per ounce indoors and as low as $15, depending on how much I grow.

Note: I also get THC vape cartridges, $25.00 per 1 gram cartridge at the LivWell weed store while in Colorado. I think that’s a good deal.

Another Note: Black Market weed in the Midwest is around $225 per ounce which is the around the same price as illegal online weed. What a rip. The Black Market and online guys are cleaning up because my cost is actually more than their cost and they can get away with the high retail price because the legal medical and/or recreational weed in the mid-west is sold even higher than $225.

I buy my regular seeds here-click the banner then search regular seeds and you’ll see a ton of regular seeds for sale.

To be able to legally sell home grown weed would be so awesome but will never happen as long as the government has their claws in the industry. IMO, the worse thing to happen to marijuana is making it legal and controlled. It doesn’t need control or legalization, it needs nothing except be taken off the DEA list of drugs.

I’m stuck back at home for the winter saving money until we can hit the road again. Since I’ll be here for a while I started growing, popping my seeds the first week of November 2021.

There are a few things different with this grow.

  1. I’m using bag seeds I found in recently purchased weed in Colorado. I had no idea the strain, or the type of seed.
  2. I’m using 5 or 7 gallon fabric pots for the most part. I’m using a few 2-1/2 gallon pots because I’m low on soil mix.
  3. About the best thing that happens turning 70 years old; my income dropped liked a rock because of Covid-19 and I qualify for utility help. My electric bill is fixed at $45.00 per month no matter how much juice I use to grow.

I’ve been buying my seeds retail from Robert Bergman for several years now and I recommend him because I know you won’t get ripped off as they guarantee their seeds as well as delivery. All you have to do is contact them if you have a prob.

As you know, your electric cost is the number one expense when growing indoors at home. After analyzing my electric bill, it’s gone up about $50 per month since I stated growing. I’m using five, Mars Hydro 1000 watt white LED lights, and two, 300 watt older fashion purple LED lights along with 2 timers and a fan.

I started 10 bag seeds and they all popped. My plan was to let the seedlings grow until I could take one or two clones from each. Then I’ll mark the pots the mothers and their clones are growing in with the same number.

Using my grow tent I started to flower the clones using 12 on 12 off lighting so I could identify the males and females while their mothers were growing in another room in the veg cycle. I won’t lose any time doing it like this. You could also flower all the plants. You’ll be able to identify the males from the females then revert the females back to the veg cycle to continue growing.

First thing I noticed were five mothers in the veg cycle were starting to flower. I’m not an expert on auto flower plants but from what I’ve read, seeds from auto flower plants aren’t necessarily female, won’t produce plants that automatically flower and will most likely grow into hermaphrodite plants.

All the seed was from retail pot purchased in Colorado over the past few years. All I can surmise is that retailers are selling weed grown from auto-flower seeds. It’s surprising to me because IMO, over all, AF are a pain to grow, have less THC and the plants are smaller with lighter yields.

Out of the 5 mothers left, two were males and three were females. I was able to get six clones from three mothers and those will grow in the grow tent under 20 hours on and four hours of light off while their mothers are in their third week of the flowering cycle using 12 hours of light on and off.

The clones from the auto mothers started flowering so they are sharing a 2-1/2 gallon pot. I moved them into the flower room and we’ll see how they do. I can’t split them up because I don’t have enough soil mix and I don’t want to buy any.

In the past when I’ve grown auto flower seeds I used 14 hours of light and had good success. I like how they look with 12 hours of light so if I ever grow auto flowers again I’ll go with 12 hours of light on.

As it stands right now, from 10 bag seeds, I have the 4 original auto mothers plus 4 auto clones plus 3 females growing under 12/12 lights. I’m using four, Mars Hydro 1000 watt, white, LED fixtures and two, older Mars 300 watt purple fixtures for the flowering room. IMO the Mars 1000 LED fixture is a great deal. I’ve been using them for 2 years and they work perfectly.

In my grow tent I’m using one, Mars Hydro 1000 watt fixture. There are seven, five week old female clones. They will be in the veg cycle until they reach about 42” or so then I’ll switch to 12/12 light and start the flower cycle. I would like to veg my plants longer but because of limited ceiling height I have to be careful.

All the clones started flowering so I have them under 12/12 light. I’ve been harvesting the other plants and they are all leafy, not very sticky and frankly the weed blows. I barely get a 10 minute buzz.

In conclusion, you cannot trust modern bag seed anymore. Every seed I’ve grown found in recently purchased retail weed grows crappy plants.
