Different types of marijuana

I will be talking about the differences between the Indica, Sativa and Hybrid cannabis types. They’re all marijuana but the differences are huge. Not only in appearance but also in growing needs, smell, taste, high and medicinal qualities. Here are some main differences between the three main types.
Also make sure to check the article “Different types of marijuana” to see what type you prefer!

Sativa
Perfect for growing outdoor.May help with ADD and depression. Energetic, euphoric effect. Sativa’s mostly grow very tall. An artists’ favorite because it helps free flowing creativity.
Indica
Perfect for growing indoor. Looks bushy and has wide leaves. Helps with anxiety, insomnia and pains for example. Relaxing, couch-locking effect. Mostly has a strong sweet or sour scent.
Ruderalis
Has a pretty short stature growing between 20-25 inches in height. This plant has very thick foliage. Hardly contains THC. Its genetic material is used for breeding autoflowers.

How to double your harvest with autoflowering plants

Have you ever wished you could grow outdoor marijuana plants more than once per year? Well, you’re in luck because you totally can!

All you have to do is grow autoflowering marijuana plants rather than photosensitive ones.

If you plant the first batch early enough in the year, then harvest them and plant a second one during the middle of the summer, you can accomplish two harvests in the span of one grow season!

That’s right, folks, that means double the harvest (in theory at least).

And as a bonus, they’re really easy to grow!

Are you excited?

What is an autoflowering marijuana plant?

Most marijuana plants are photosensitive (or photoperiod) plants. That means that their life cycle changes are based on the changes in lighting caused by the sun. Once they start getting a certain amount of uninterrupted darkness, they will begin to enter the flowering phase. This is their way of sticking with the seasons and flowering before it gets too cold for them to survive.

It used to be that autoflowering plants were always ruderalis strains (which are low in THC). They weren’t popular with the general marijuana crowd for obvious reasons, but once they were cross-bred with indica and sativa strains (high in THC), they created the autoflowering beauties we now see today.

What’s with the hype?

There are tons of reasons why everyone is excited about autoflowering marijuana plants. They include (but are not limited to):

  • Smaller in size (my nephew has a couple in his windowsill)
  • Fast growing
  • Great resistant to pests and diseases
  • Shorter grow season (ready to harvest in 10 weeks)

Check out the way autoflowers grow!

Have you ever seen an autoflowering marijuana plant grow? It’s known for its fast growing. We got an awesome timelapse where you can see a little one come up!

What you need to know about autoflowers

The main thing to consider is the fact that no two strains of autoflowering marijuana plants are the same.

Simply ordering “autoflowering” plants is not going to cut it — you’re still going to have to do your research.

The main thing to know about autoflowers is that their lifespan is shorter. So, it’s extra important to start out strong with the grow season because there is less time to compensate for a slow start. That means you should give your seedlings a lot of love!

If your first harvest is disappointing, just remember that you have a second try! In fact, your second grow cycle may be better mid-summer because they’ll get more sun right off the bat.

How Much Marijuana Can I Yield Per Plant? A Pound!

Marijuana A pound per plant

One of the most popular questions regarding marijuana is “How much marijuana can one plant produce?” or “How much will a 600 watt HPS yield?” There are no simple answers to this question as each situation depends on a number of variables.

Many people take up growing weed and they have a variety of reasons for doing so. In every case, you want to get the most out of your crop. Whether you’re growing for medical reasons or you just want to make a little money on the side, the overall yield is a top priority for all growers.

In this article I will discuss all everything there is to know about marijuana yields. Got questions or tips? Place them in the comments below this article.

Maximum yield per plant indoors

Lights are of the utmost importance when you’re growing indoors. Experienced growers can produce about a gram of marijuana per watt of light (1 gram = 0,035 oz). So, a 400-watt HPS grow light can potentially translate to 400 grams or 14 oz of dried, usable cannabis.

HPS grow light

600watt HPS grow light with reflector

Likewise, a grow room with 1200 watts of light can yield 1.2 kilograms or 42 oz of cannabis. Having the right equipment, adequate nutrient solutions, beneficial air quality, and other valuable factors is important for producing the highest yields possible. Making sure the plants have space to grow is also key.

Average expected yield per plant indoor from soil

If you are using soil to grow indoors, you can expect somewhat less of a yield than if you’d grown hydroponically. This is because hydro growers can fully control the amount of nutrients their plants receive.

Check out these pics below. You can see that hydro plants grow faster than soil plants

Although soil growing can potentially lower your yield, it also is easier to grow. This is because it not only creates a buffer for error but it also holds nutrients within the soil. When growing in soil, there is room to make mistakes with pH and TDS and pay for it in yield. In terms of numbers, expect a maximum of 1 gram per watt. That means a 600watt lamp can produce 600 grams of marijuana or 21 ounces.

Average expected yield per plant indoor from hydro

Growing hydroponically yields up to 20% more, as long as you do not make any mistakes. With hydro growing, there is no room for errors. You must be very careful about the TDS and pH levels because the roots are directly in water (and not soil) and incorrect levels can immediately effect the plants.

Check out these pics below. You can see that hydro roots grow faster than soil roots

There are rarely small mistakes while growing hydroponically. Even the most minor error can ruin your yield. However, those who do it correctly will be rewarded. You can expect up to 1.2 gram per watt, which means a 600watt HPS lamp can give you 720 grams of marijuana or over 25 ounces.

Cannabis plant yield calculator

A simple way to calculate your yield is by using a cannabis plant yield calculator. Yield O Rama has an excellent one that lets you select the type of light you’re using, the light intensity (lumen), your level of growing experience and your growing medium.

Marijuana yield calculator

When using the yield calculator, keep in mind that an HPS grow light produces around 150 lumens per watt. For the exact amount of lumen that your bulb produces, check with the manufacturer.

The calculator has a few limitations- you cannot adjust it for the strain, and it’s only for indoor grows, but it is still quite handy. Check out the cannabis yield calculator here.

  • An average of around 1.5 to 2.0 oz  (3.5 oz for advanced growers) with 200-watt CFL lamps in a grow cabinet that measures 3.5 x 1.5 x 6.5 ft.
  • An average of around 3.0 to 5.0 oz  (9.0 oz for advanced growers) with a 250-watt HPS lamp in a grow cabinet that measures 3.5 x 1.5 x 6.5 ft.
  • An average of around 4.5 to 9.0 oz (14 oz for advanced growers) with a 400-watt HPS lamp in a grow room that measures 3.5 x 3.5 x 7 ft.
  • An average of around 5.0 to 10 oz (21 for advanced growers) with a 600-watt HPS lamp in a grow room that measures 4 x 4 x 8 ft.
  • An average of around 9.0 to 18 oz (36 for advanced growers) with a 1000-watt HPS lamp in a grow room that measures 5 x 5 x 8 ft.

  • An average of around 100 to 250 grams (400 for advanced growers) with a 400-watt HPS lamp in a grow room that measures 1 x 1 x 2.5 m,
  • An average of around 150 to 300 grams (600 for advanced growers) with a 600-watt HPS lamp in a grow room that measures 1.2 x 1.2 x 2.5 m.
  • An average of around 250 to 500 grams (1000 for advanced growers) with a 1000-watt HPS lamp in a grow room that measures 1.5 x 1.5 x 2.5 m.

How much does one marijuana plant produce

Indoor growth doesn’t bring with it a lot of certainty in terms of yield per plant. If you have only four plants per lamp, then you’ll yield much more than you would with total of sixteen plants for every lamp.

You should consider these things prior to choosing how many plants you want to grow:

  • If you’ve only got 4 plants, your yield will be 25% less if one gets a disease or dies

 

splitting the stem of your marijuna plant?

splitting the stem

Not many people know about this trick, but I’m sharing it with you today. Have you ever heard of splitting the stem of your plant?

No? Well, did you know this will force your plants to create heavier and denser buds? And it also increases THC production up to 20%!

Don’t hesitate and order your seeds to try out this trick with your plants as well!

split marijuana

The purpose of stem splitting is to disturb the flow of nutrients and water right at the base of the stem.

This will cause the plant to start producing more trichomes which means heavier and denser buds with higher THC levels.

Make sure to read my article How to split the stem to increase THC levels in my FREE Marijuana Grow bible after I tell you how to do this in 3 easy steps.

How to split the stem in 3 easy steps:

Step 1 Tie the stem with a rope or cable tie right at the base. Tie a second rope or cable tie a couple inches above that.

Step 2 Take a very sharp knife and cut from the top tie to the bottom tie. There should be one vertical cut that is a few inches in length.

Step 3 The knife should remain inside until you have a pencil or chopsticks to replace it with. This is to keep both sides of the marijuana plant from touching each other.

Check out this picture gallery and learnHow to split the stem.

Splitting the stem causes stress on the plant and forces it to create more trichomes.

Trichomes serve as protectors of the marijuana plants. Specifically against pests, diseases, low temperatures and wind.

Because of this protective feature, more trichomes are produced during times of stress. Take advantage of this special feature and read about splitting the stem and many more secret tricks to grow huge buds and increase your yield.

Tip 1: Apply this technique 3 days or a week before harvest, not sooner!

Tip 2: Try it on only 1 of your plants until you’ve mastered the technique

Tip 3: Ever extended the dark period to 48 hours right before harvest? Read more here

What is the best grow light?

What is the best grow light?

For indoor growers, you will need to choose a specific type of light. Growers use CFLs, LEDs, MH lamps, HPS lights, and more.

CFLs are most commonly used by beginners since they are so inexpensive. If this is your first time, it might be a good choice.

LED lights are higher in power and higher in cost (significantly) but they require less electricity than MH or CPS. The latter cost less than LED upon purchase and highly powerful but require quite some more electricity. If you have a small grow setup, however, CFLs are likely the simplest choice for you.

If you feel like splurging on the very best, go for a smaller MH/HPS grow light instead.

Which growing medium to choose

Most beginner growers start with soil, since it is the easiest option out there for the inexperienced among us. If you want to try something besides soil, you can choose between perlite, coco coir, vermiculite, and more.

These are considered soilless mixes, which are a type of hydroponic growing, technically speaking. Hydroponics involves growing your marijuana plants directly in water, which can be a complicated system but a highly fruitful and rewarding one — it is said that the highest yields are achieved in hydroponics systems.

Of course, you can also go the organic growing route: composting your own soil. It takes more work but leads to great taste and yield results, plus it makes for a very wise choice for the environmentally minded.

How To Make Marijuana Clones

how-to-make-marijuana-clones-36051-w800

The knowledge and ability to make marijuana clones is an added bonus for any successful grower – as well as growers of any type of plant. Cloning is a reliable way to have a better harvest and yield without risking certain important factors such as potency. As long as you know which of your plants are the healthiest and most successful, as well as which are males and females, you will be able to clone correctly. If you don’t know these things at this stage in the growing season, you may want to take up a new hobby.

You might even have a specific favorite plant already, which will make the decision process quite easy when it comes to cloning. Cloning is about as close to a guarantee as you can get in the marijuana growing business, so proceed with confidence because it has a very high success rate.

This article will help you successfully clone any plant that you want. We will cover the various methods for cloning and transplanting, as well as more advanced techniques and options that you as the “cloner” can look further into if you are interested. Keep reading and learn to clone like a pro!

What is cloning

What is cloning weed plants

Cloning marijuana plants itself is actually just using the clipping of one of your plants and moving it elsewhere to begin growing by itself. It’s as simple as that!

While the theory is extremely simple, the actual practice isn’t foolproof for some people. For outdoor growers, cloning is the most successful when it’s done in a region with a long growing season. Even with a very long growing season, you can’t expect your clones to reach their full height potential. This is unlikely since they will only start growing about 3 months into the growing season when your original plant is mature. That being said, even short clones can end up with a superb yield, sometimes having a top full of buds.

Most cloners prefer to take the bottom branches from their plants since those branches would receive less light and struggle for survival anyway. If you take between two and four of each of your plant’s bottom branches to make clones, you have at least doubled your harvest. Do you understand now why cloning is such a popular practice?

Although cloning is relatively risk-free since it does not risk the health of the original plant and your main harvest, clones often die before they are even able to root. It is not uncommon for just one out of ten clones to survive, so don’t be discouraged when most of them die.

Select a mother plant

Select a mother plant make cannabis clones

Don’t be hasty when you are trying to decide which of your plants to clone from. You need a plant that is hardy, growing rapidly, with great yields, large roots, and strong buds. When taking cuttings to clone your plants, you should make sure that your plant is in a vegetative state. If you take them during the flowering stage, then it will become much more difficult for your plant to take root, thus making your clones’ mortality rate will be higher.

If this is your first time cloning, then you may not actually know your plants well enough or have enough experience to know which ones are the best to choose. Regardless, if you choose a female that is in its vegetative state that appears relatively healthy, then you are probably choosing one that will work fine for cloning.

At the absolute minimum, your chosen plant needs to be two months old. In fact, it should have been in the vegetative state for two or three months already. If you wait this long to remove branches for cloning, then you should be able to get many clones from the one plant.

Once you decide on a plant, be sure to prepare it properly. It should receive ten percent less nitrogen than normal starting a week or two before you clip its branches. This will help its clones have a higher chance of successful rooting after you have clipped them off.

Cloning Techniques

Cloning techniques weed

When you cut the branches from your plants, make sure you end up with 6 to 8 inches of each branch. Also be sure to leave at least one pair of leaves on the branch so that two new branches can sprout. Remember to cut out branches from the bottom, since they aren’t as productive as branches higher up on the plant anyway. This will promote faster rooting in the clone. That being said, you also might want to consider cutting from the top if you want the resulting plant to flower more quickly.

You will need a knife that is quite sharp (to avoid any ripping during the cutting process). Make sure you always cut diagonally, since this will maximize the surface area from which roots will hopefully sprout. Buy cloning gear like knifes, rooting gel and rock wool cubes at this link

Rock wool method. All you have to do is trim healthy cuttings from healthy plants. Make sure to clip off most of the leaves, but leave the top ones intact. Dip each cutting in rooting gel or powder and then place it in a rock wool cube under a CFL light. The ideal temperature is around 72-75*F (22-24*C). The roots should start showing up in 8-12 days. Make sure to soak the rock wool cubes in pH 5.5 water for a few hours.

The Potting Soil Method. Because you will want the cutting to use all of its resources and energy for sprouting roots, take away any mature leaves that are on the stalk. Then wet the sliced bottom of the stalk and dip it into rooting gel or powder. Right after that, stick the plant into the saturated potting soil under cfl lights, where it should remain while roots are forming.

The Water Method. You should also remove the mature leaves from the cutting with this method. After that,  get a container of some sort (a plastic bottle of about 16 ounces is best, since it has a narrow neck that will be helpful in holding the plant up) and fill it with water that has been treated with plant food. Submerge the stalks of your plants into this water and leave them there, mixing things up every couple days to make sure algae doesn’t grow too much. If you do discover an algae problem, you can change the water.

Keep sunlight indirect or less intense than normal until new leaves are growing at the top. This new leaf growth usually happens at the same time as root growth. You should soon have a nice ball of roots as a sign that it’s time for a transplant.

Transplanting clones

Transplanting cannabis clones

Since you probably have already transplanted your seedlings during this growing season, you will already have the knowledge for transplanting your clones that have rooted in soil.

Clones that were rooted through the water method, on the other hand, will require a new technique. First, dig a hole that is one foot deep and one foot wide. You will then need to move the actual container that is holding the rooted plant and its water all the way to the site where you will transplant it. It is crucial that you do not expose the roots to the air, so despite the inconvenience this is an important part of the transplanting process.

Put the plant in the hole and fill the rest of the hole with potting soil mixed with dirt that was dug up. Pat down the soil firmly but gently, then water the entire area with a half gallon or more of water mixed with plant food.

In general, clones that have already taken root have a very high chance of survival. This is simply because the original plant they were a part of were already mature and strong, meaning that a clone with roots is no different. It should begin the flowering stage within two or three months. Take note, however: sometimes the clone ends up being a different sex than your original plant, so don’t be shocked if it happens.

Caring for your clones

Caring for cannabis clones

You should keep your Marijuana clones’ grow room temperature a bit warmer than standard room temperature, so between 72 and 77 degrees Fahrenheit. Since cuttings don’t have roots yet, watering the soil around them will not do any good. Instead, spray them with water several times a day so they can absorb the water through their leaves. You may also want to consider spraying a mild nutrient solution as well. Make sure it’s also hitting the leaves since they will also absorb the nutrients through their leaves as well.

If you invest in a mechanized cloner, you won’t have to worry about monitoring the moisture or temperature. The cloner will do it for you, thus (more or less) automating the entire thing.

Some growers make the decision to not use any lights at all for a day or two while the clones are adjusting to their new surroundings. Others start with a bright light and then use a dimmer grow light after a couple days. For roots to form, you should also ensure that there is at least some darkness each day. Try 18 hours of light and 6 hours of darkness.

When you are using powder or gel that is designed for rooting, ensure that it has been stored properly. It, like many products, needs to be stored in a cool, dry place. If there’s any chance that it has been contaminated, definitely do not use it under any circumstances. Whether the packaging wasn’t sealed properly or anything fell into it, even natural materials like leaves or dirt, it could have a negative effect on your plants.

In general, the most effective way of giving your clones a chance at growth is to keep a constant, close eye on them.
