The four most important factors that go into maximum yield are as follows in order of importance: Genetics Often overlooked, it important to realize that genetics is the number one factor in obtaining maximum yield. As in raising any living organism, the genetic foundation is everything. The reason…
Factors that Maximize Yield

According to science there are 16 essential plant nutrients. These are divided into two groups: Macronutrients - carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, sulfur and magnesium are required in large amounts.  Micronutrients – iron, chlorine, manganese, boron, zinc, copper an…

pH is a scale of 0-14 which measures the acidity or alkalinity of a nutrient solution. This scale can be measured by its concentration of hydrogen ions. Pure water is neutral, neither acidic nor alkaline (it has the same number of positive charges (H+) as negative charges (OH-) which is a pH of 7. T…

Hydroponic gardens offer the root zone water without having to expend energy to look for nutrients or oxygen over larger areas. Due to the high availability of water this can cause the plant cells to swell giving the impression of a larger plant. This will also increase the fresh weight of a yield;…

RockWool Rock wool is the most widely used medium for hydroponic gardening in the world. Rock wool is an inert fibrous medium produced from a mixture of volcanic rock, limestone, and coke, melted at 1500 to 2000 degrees Celsius. The fine threads are pressed into woven sheets. Rock wool is slightly a…

Drip Systems When running these types of systems it is important to keep the root zone moist, this does not require as much water as it appears. It is not necessary to run a continuous open flow of water through the root zone. This will actually limit growth as the root zone will always be covered w…
Common Hydroponic Systems

What is typically called a dirt garden is not true soil. Peat and perlite are hydroponic mediums. Contrary to popular belief the yield and quality can be just as good. A dirt garden can be easier to manage for beginners granted they have the proper tutelage. If there is a large investment involved a…

Starting a plant from seed will not only produce a genetically fresh specimen it will also, if done correctly, ensure that the stock is disease free. Some gardeners neglect to see the importance of taking their favorite strain back to seed every few years. This can lead to a genetically tired plant.…
Starting from Seed

Producing plants by cloning is by far the most common and favored method of propagation as it is the quickest. Plants that have been cloned are already genetically mature; this enables a gardener to induce flowering with reasonable assurance that the plant will respond consistently. Due to the head…

Thorough planning is required in setting up any garden, and each one is usually tailored to the particular circumstances of the gardener. There is no absolute right way; there are many ways that will provide a beneficial environment. There are, however, basic pointers that when followed can save a w…
Setting Up the Garden

The reason that plants produce a premium crop indoors is due to the consistency of the environment. Plants love consistency. Consistency is achieved by using environmental controls to monitor the environment and maintain the parameters that have been set. The optimum environment is 80-85F lights on,…

It is necessary to match the correct ballast with the correct bulb (recent developments in electronic ballasts are offering units capable of running…

Carbon Dioxide (CO2) is processed into 45% of dry plant matter thus comprising half of our yield. CO2 is an absolutely necessary component of the process of photosynthesis. Without adequate CO2 to process water, light and nutrient, the light will literally bounce off of your plant. This makes CO2 on…

The main methods of odor control are ozone generators and charcoal filters. Charcoal filters have definitely become the preferred choice in odor control as they do not break down and do not produce an alternate odor such as ozone which is easily recognizable.

It is very important that the crop is flushed for 7 days with a flushing agent, or 10 to 14 days with straight water prior to harvest. Misting plants with straight water is what is termed reverse foliar feeding and will have the effect of leaching out the excess nitrogen. If your plant is turning ye…

Powdery Mildew To date there are thirteen different strains of powdery mildew some like to be dry, some like to be wet. The most common one in indoor gardens likes a hot and dry environment. Earliest signs will be a round white patch starting on the top of the leaf. Left unchecked it can cover the l…

To boldly grow where no man has grown before

There's a political side to me. There's also an organic side to me. I see things through spiritual wisdom and corporate efficiencies. We all want to improve ourselves and our lives and that's why we're all here.

I don't have much patience for people who hurt others for their own petty gains. In fact, I'm likely to punch you in the face if that is you.

I love driving and travelling into unknown territories filled with new people and things to experience. I also love coming back to the places I've been before.

You may have heard of me, I'm kind of a big deal. :P

the Garden Sage tm.


is a true cash crop professional that has been guiding gardeners to their greatest successes for over fifteen years. Working full time on the retail floors of busy hydroponic stores in British Columbia has allowed the garden sage to deal with an incalculable variance of challenging situations. With years of professional teaching experience under his belt he knows exactly what you need to know to increase your yields. Highly sought out for his valued consultation he has improved countless yields and directed the set up of thousands of gardens. He has been told many times that the information he has imparted in less than ten minutes has tremendously boosted yield resulting in increased profits.


Dear Fellow Growers,

Born and raised is surrey BC I grew up enjoying the fruits of our local harvest. In my early twenties I began working full time in hydroponic retail. This was like hydroponic boot camp! Back then - in the nineties - BC was EXREMELY busy, and Surrey was like the Meca.

After five years full time in such a demanding environment I thought I was a pro! I would tell clients what to do, they would do it, and things would work out.

When I began designing a course I realized I knew what worked but not 'why'. In my studies I finally understood the 'why.' I obtained the working model of a plant in my mind. I went on to teach very successfully for 2 years.

Over the last 10 years I have made this book concise and without distracting information. I know what you NEED to know. This is the book that I have been looking for my whole career and I had to write it to get it.

I put all of my jewels in this book - 15 years - 8 hours a day – tens of thousands of gardeners who have each done dozens of crops have brought their problems to me. This information is not opinion based but statistical information gathered from collective experience.

What is so special about this information you most certainly ask? Well, there are some aspects of knowledge and concepts that I have never seen put forth like my factors that create maximum yield in order of importance

  1. genetics
  2. environment (lights on temp/off temp, air movement, humidity levels, co2 levels, etc.)
  3. the system/the grower/cultural techniques/mistake/accident factor
  4. nutrients and additives.

You will probably notice that new gardeners conceive this order of importance in the opposite. They think that the solution is in a bottle and that they have to find the ultimate system. Logic will show the truth – good genetics in a good environment will usually yield well in many different systems with many different nutrient programs (I explain this in detail in my book).

Other parts of the knowledge may simply fill in gaps in current understanding. The real advantage of this knowledge is how it is delivered. It is designed to teach. To impart the working model in the mind of how plants actually work .

I have received excellent feedback on The Growers Handbook (it has been selling since December 2010). I truly believe that this is the most value packed $30 a person can spend on a indoor gardening book. You know how it is - some questions are $10,000 questions!
Readers love that they can read this book, containing all the essential knowledge, in a day or less. Some, read it cover to cover a few times and feel that the info has really become theirDavid and Phoenix own, others like to read each section individually as it pertains to the activity of the day.

If you want to grow indoors, someday, you will probably go into a hydroponic store to make purchases for your garden and I am the guy that you would want to find on the other side of the counter. Now, I can't be there to serve all of you, but I can give you my special understanding.

I am confident that everyone can benefit from reading this book, even if you have been growing for twenty years and that is my sincere intent.

Getting back to the Garden,

the Garden Sage
