About Silas Sativarius

Silas Sativarias

With an educational background in science and electrical engineering, Silas Sativarius has over 30 years of consulting expertise in commercial lighting technology, environmental controls and systems, and computer systems and networks. His clients have ranged from major corporations to universities. Hence the necessity of using his nome d’ plum Silas Sativarius.

Roughly 10 years ago, sometime after the immortal 420 law was passed in California, Silas, a long-term advocate against drug prohibition and in particular the patently ludicrous demonization of Cannabis, jumped into the grow-your-own movement with both feet.

But Silas can never just DO something. A chronic infomaniac and subsequent know-it-all, (he would annoy the shit out of you in person) Silas has to become an EXPERT on anything and everything he does. And so over the last 10 years he has applied his deep scientific knowledge and hunger for information to cracking the code of OPTIMAL cannabis cultivation.

Silas has amassed a deep and thorough understanding of ALL the factors that affect this miraculous plants growth and health, and in this forum he will provide you the reader with the knowledge and expertise to maximize your yield and quality, while minimizing the work and heartaches.

Forget all those supposed “experts” who are just ex-growers, would-be growers, or just trying to make a buck,  Silas is a recognized scientist and engineer who just happens to have been a passionate grower.  So in this forum he will not only discuss WHAT to do, but also give you a thorough  and detailed explanation of WHY it works.

To those who grow, we salute you!

  1. Hi Silas, I’m another engineer who decided to grow. I’m really working on root zone temperature using aeroponics. I noticed that you do not want roots to be any hotter than 75F. What are your thoughts on the 1944 Nelson paper on hemp with root temps of 84F that did just fine?

    1. Great question Kirk. The suggestion of keeping root temps below 75-78 stems from the fact that the oxygen content in water drops rapidly above that temp. Obviously if you have a system that can provide oxygen without dissolving it in water, then higher temps can be efficacious. I don;t remember where, but I did mention that plants actually do continue to grow faster as the roots get warmer so there is some advantage, but you have to weigh that against the problems that can come with lower dissolved oxygen. So it is a tradeoff. But yes, if you can manage you flora and air in the root system I suppose you could run the roots as hot as the plant and see metabolic increases from it. I tend to be somewhat cautious in this since no where in the world do soil temps ever rise above around 70 so plants and the root flora have millions of years of evolution supporting that temp. Bottom line, if you can keep enough air to the roots without dissolving it, such as aeroponics, then you should actually see gains in growth rates from higher root temps. Thanks for the great question..

  2. Silas,
    I stumbled upon your site in an effort to better understand the relationship between temp/RH/CO2 and found a gem. I really appreciation your freely giving of information that you’ve spent years studying and hammering out. I’m a relatively new grower but, have had a love for this plant for more than half of my life. I am a person who isn’t satisfied with satisfactory and love to learn. Thanks for what you do and helping me
    become a better grower and understand this wonderful plant more deeply.
