Welcome to

Growing Marijuana With Subcool
– An Introduction

I’d like to introduce myself for those of you that might not have heard of me. I have worn many hats in my life, a dealer, a grower, a breeder, a photographer, a journalist, and marijuana enthusiast.

I am a Hightimes Magazine Lifetime Achievement Award Winner but label that fits me
best is simply “Weed Nerd,” as I love everything about growing cannabis and the culture surrounding this magical plant.I am the founding marijuana strain breeder at SUBCOOL SEEDS and one of my strains “Vortex” won the first ever United States medical marijuana Cannabis Cup.

I’m the author of the “Book of Dank” as well as “Dank 2.0.”

These books are collections of cannabis photography and the stories that go along with each.
I’m a contributing writer/photographer for High Times, Treating Yourself, Heads, Skunk, Weed World and West Coast Cannabis Magazine Dope Magazine, The Grow Tube Roundtable Big Buds Magazine and many others.

I have designed this section to hold a vault of all the information available on the Web by me. I hope to teach my simplified methods to a whole new generation and I am very excited to reach a new audience. I have created a growing marijuana method that anyone that can follow, with simple instructions and perform the physical effort required can duplicate.
It has taken on the nick name the “Just add Water” method.

My Youtube Channel is quite popular and has over 7 million Views.

We call it Super Soil and it was derived from and old forum online run by Vic High the creator of Killer Queen and other famous strains.
Over the years I have changed Vic’s recipe substantially each time making small changes to improve the end results. The current recipe is used by people all over the world with many going to extra effort to use the exact same ingredients down to the manufacture.
Others get as close as possible using what products they have available to them with equally stunning results.

I expect people to question and make their own small changes and test the results from crop to crop.

Other topics I will cover in my marijuana growing articles will be my form of LST I call Bondage cause hey everyone likes a little of that.
Early topping and training, transplanting, cloning, trimming, making tinctures and extracts will all be covered in great detail but with my simple easy to understand way of explaining things.
I like to tell my stories with pictures as well so you will see lots of detailed photographs to help get the point across.

I will also be talking about marijuana genetics and current breeding projects I am working on for Subcool’s The Dank and showing off the latest bud porn from my travels around growing marijuana world.
I hope you make my section a weekly read, so you get the most out of your Subcool Seeds and all the other strains you grow.

New Creations from Some Of the Best Breaders In the World


  • The main man at TGA Seeds is “Weed Nerd” Subcool. He’s the driving force who’s created dozens of tasty, potent, unique marijuana strains in the past decade.

    We’ve talked about Subcool in many articles, and he’s written many fascinating articles for

    We asked him to provide a vocabulary list for words used in marijuana seed breeding.

    When you do marijuana seed breeding correctly, you gain genetic control over the kind of marijuana plants you grow, and the high you get.

    Take a look at the information provided by Subcool below, and this other marijuana seed breeding article.

    And when you want to get deeper into marijuana seed breeding, get the book Marijuana Botany, by Robert Connell Clarke.

    It’s an old book, but still considered the best explanation of marijuana breeding techniques and strategies.

    Now here’s Subcool’s marijuana seed breeding definitions list:

    Allele : One possible form of a gene that defines a genetic trait. All organisms have a pair of alleles for each trait, one allele for that trait received from each parent.

    Dominant : Said of an allele which by itself alone will produce a particular phenotype regardless of which other allele may be present on the other matching chromosome of the diploid pair; thus it takes only one copy of the chromosome to cause a dominant trait to be expressed in the phenotype.

    F1- generation : The progeny produced from a cross between two parents (P1) is called First Filial or F1 generation.

    F2- generation : The progeny resulting from self hybridization or inbreeding of F1 individuals is called Second Filial or F2 generation.

    Genome : The total genetic information possessed by an individual, a breed, or species.

    Genotype : The invisible genetic makeup of an individual organism, which includes alleles that may be recessive and therefore have no visible physical expression.

    Homozygous : An individual possessing (receiving from parents) identical alleles for a trait is said to be homozygous or pure for that trait, e.g. plant with RR alleles is homozygous for the seed shape. A homozygous always breeds true for that trait.

    Inbred Line- (IBL) : A cannabis seed line produced by at least five generations of sequential inbreeding, self-fertilization or backcrossing, accompanied by selection within and between lines so that the individuals are considered to be homozygous, or nearly so.

    P1: The name of the parent to which a marijuana hybrid is crossed in a backcross.
    Phenotype : The external (morphological) appearance of an individual for any trait or traits is called the phenotype, e.g. for seeds, round shape or wrinkled shape is the phenotype.

    Recessive : Said of an allele which will only produce a phenotype if the identical allele is present on the other matching chromosome of the diploid pair; thus it takes two copies of the chromosome to cause a trait to be expressed in the phenotype.

    As you can see from reading these definitions, there’s more to learn, and Clarke’s book is a great place to start.

    It’s worth it to learn how to do more than just grow out marijuana males and put their pollen onto female flowers.

    If all a person does is take male marijuana pollen and put it on female flowers, the seeds resulting from that kind of marijuana seed breeding aren’t going to grow out to be stable, consistent, and reliable versions of what you’re looking for.

    Maybe you could be the next Subcool–breeding incredible marijuana and selling tens of thousand of your seeds worldwide!

  • Marijuana seeds have many benefits when compared to growing from clones.

    The most helpful benefit is that marijuana plants grown from seed do not introduce pests or problems into a garden like clones can.

    Another benefit seedlings provide is health and vigor. Sometimes marijuana motherplants and/or clones can be old, tired, or even diseased without it showing visibly.

    Many growers opt for feminized seeds, but I feel that you do best, and can have efficient seasons, using regular marijuana seeds.

    One key factor for good germination is to select the right brands and strains of seeds.

    When selecting seeds, do homework online and find out what marijuana strains the  most successful marijuana growers are growing.

    Find out which companies are creating the best seeds, and choose carefully.

    A seed needs moisture and the right temperature so it can germinate.

    I recommend germination temperatures between 70-80 degrees. Temperatures in that range tend to produce a higher ratio of female marijuana plants. Temps higher than that create a higher ratio of male marijuana plants.

    Many marijuana growers still use the tried and true method of germinating cannabis seeds in a wet paper towel.

    With the invention of rapid rooters, you can get better germination. They’re made from composted organic materials bonded together with plant-derived polymers.

    These plugs are manufactured using a scientifically controlled process that yields large populations of beneficial microbes in the medium. We started using them to clone about three years ago and when I tried starting marijuana seeds in them, I knew I would never do it any other way.

    I flip the cone-shaped rooting plugs upside down so they have more stability.

    They’re made to fit into sectional trays, but that just adds cost and I try to keep things simple and low frills.

    Wash your hands well with a disinfecting soap to remove any oils or contaminants before you handle marijuana seeds.

    Make a small hole with a poker and place the seed point side up into the plug about ½ inch deep into the rooter.

    Place the plugs into a domed container and place it under florescent lights. I like to use plastic/Tupperware shoe boxes stacked on top of each other. They’re low cost and easy to find at any department store. Not everyone has access to a hydroponics grow shop at all times.

    Don’t let the cubes dry out.  That is really the only thing to worry about.

    It’s best not to drown them, but as long as they don’t dry completely I have always had great success using this method.

    Once the marijuana seeds sprout, I transplant them into one gallon pots filled with good quality potting soil, but make sure the soil isn’t too nutrients-rich, or it will be too nutritionally “hot” for your plants and will damage your seedlings.

    My company, Subcool TGA seeds, works hard to create unique marijuana strains and seeds that are guaranteed to have near a 100% germination rate and to grow out to be exactly what you wanted when you bought them.

    Check out the many articles written about TGA strains and TGA personnel, and my internet marijuana television program, Weed Nerd. I can’t vouch for other marijuana seed companies, and I often hear from growers that seeds from other companies have low germination rates and other problems.

    What I can assure you is that my passion in live is to help more and more people grow fantastic marijuana, and this is what motivates TGA Subcool seed breeding.
