    I am happy that you have found a system that works for you. I will go with my scientific evidence, and decades of experience over the anecdotes of an old fogey. Too each their own!

    Cannabis Photoperiod Hacks

    Hi Submarine Girl, The intensity of light pollution is more important than the duration. A brief exposure to light during the night period can affect the photoperiod if it is of sufficient intensity. If you can read a large print book when your light is on, it will affect the plant's...

    Cannabis Photoperiod Hacks

    Hello MP Friends, A lot of growers are leaving money on the table due to a failure of imagination. The idea that cannabis should always veg at eighteen hours of light and flower at twelve is wrong. Cannabis plants do not require total darkness to flower and trivial light leaks will not...

    Clones dying

    How to Grow Better Autoflowers

    Happy 4/20 Marijuana Passion! I have a confession to make. I am big on autoflowers and have been for a long time. I have been teased mercilessly for this by other commercial growers, but I really don't give a snit. I just published an article on growing autos, and I would love to get some...

    Hi, I'm Stew

    Hey Big Sur, Obstacles are interesting. I am always encountering new issues that are difficult to diagnose. Fusarium is a ***** indeed. If it is present in your outdoor soils there is no way to eradicate the pathogen. There are some strains with natural resistant traits, and you have to run...
