Hey,
Nice post! There are some proven & known disadvantages to using molasses however. As a career Horticulturist
I must say that molasses is not the best thing for cannabis or for that matter, put anywhere near it. The primary reason is that it is like vinegar. In the "right"amounts it does have some pest deterrent abilitys (not much though) Too much and it acts like an attractant in which the amateur (lay person) has no experience in measuring then must rely on trial & error. Which is not something many wish to do only to have their plants eaten up by sugar seeking pests! Molasses is not the best nutrient solution for growing cannabis. In my humble 19 years of growing my own, and growing for some researchers as well I have found that molasses acts like a "big turd" in the plants system (roots) as it tries to deal with sugars absorbed when applied. My best and professional advice is to stay away from it and stick with a good soil and fertilizer such as 5-5-5 to begin with. Compost mixes are best and the best is the compost pile you can make for yourself very easily without hardly much effort than tossing in your food waste at the end of the day. In the sum of things molasses is messy and attracts more pests than its worth. There is also a vast number of articles written then posted on the internet under the pretense of "fact" or penned by some scientific sounding individual but, the facts are that there is no scientific proof that molasses make cannabis (or any other plants) any bigger, better or anything purported in these articles. Many years ago a professional nursery owner wrote an article on using molasses in her plants. She stated that "she thought" it helped her plants. This is where many of these articles along with the speculation that molasses will work for cannabis originated from. I realize that many growers including some of the seed companys will tell their customers to use it but again, there is no proof that it works at all. Use at your own risk is my advice. Growers who do cite "better results" when used are more likely just the recipient of good genetically harvested seeds that did well compared to plants they grew before. In other words, their plants were going to grow great anyway and the use of molasses was unjustifiably attributed to it.
