Top 10 Myths about Growing Marijuana You Should Know

Posted on Jun 23 , 2020

Now more and more people begin to grow cannabis indoor with LED Grow lights. But there are so many grow marijuana myths on the internet, below are top 10 myths and the right answer.


#1 Determine the gender of the cannabis plant by the number of leaf spots


This is completely incorrect. Gender can be known as early as 4-6 weeks before the plants bloom. Females produce delicate white tendrils, while males show distinct miniature bananas with beads underneath.


#2 The More Nutrients, The Better The Plants Grow


Cannabis needs three key macro-nutrients to survive: nitrogen (N), phosphorus (P), and potassium (K).


The fertilizers you’ll find at a grow shop carry different concentrations of these nutrients depending on whether they are designed to be used on vegetative or flowering plants. These fertilizers deliver nutrients directly to your plants’ roots, where they can be absorbed really quickly.


Once you overfeed your plants, it will cause nutrient burn. This stresses cannabis plants, stunts their growth, and can even end up killing them if not dealt with.


#3 It Takes A Lot Of Money To Grow Marijuana


It certainly can take a lot of money to grow marijuana, but It can be as simple or as complicated as you like.


Careful planning and a little effort are much more important to a successful grow than expensive equipment.


Outdoors, all you need to grow great weed is a sunny spot, a pot with some good soil, some fertilizer, and patience. Indoors, you’ll want to invest in a decent grow light. If you’re able to grow outdoors, you’ll be able to grow a few plants for less than $50. Indoors, you should be able to set up a simple grow space for under $100.


#4 It Is Hard To Grow Cannabis


In fact, many beginner growers start by just throwing some seeds in soil. Once they are out of the seedling phase, caring for cannabis plants can be as simple as just watering, feeding, and some light pruning.


#5 Don’t Feed Any Nitrogen During Flowering Because It Will Affect The Flavor Of The Buds


Nitrogen is an important nutrient throughout the grow cycle of cannabis.It is a basic building block of amino acids, which the plant needs to produce enzymes, proteins and chlorophyll. Be careful don’t over feed nitrogen.


#6 Add Potassium To Stimulate Flowering, Increase Speed Of Flowering, Trigger Flowering Or Ripen Buds


Potassium has four major roles in the physiology of cannabis (or any other plant, for that matter).


  • Regulates water and nutrient movement between plant cells.

  • Activates over 50 key enzymes

  • Is a building block of DNA, and therefore essential for the production of new cells and healthy growth.

  • In some plant species (lemon, cotton and peppers for example) it increases the amount of fruit set.


Extra potassium is not the magic fix to stimulate bud production.It does more good to boost phosphorus to support strong growth during flowering.


#7 Marijuana Needs A Constant Temperature Of 72-79 Degrees


Cannabis like most plants that evolved in non-tropical climates, is thermoperiodic. This means it is healthiest when nighttime temperatures drop 10-20 below daytime highs.


#8 Check The pH Of Your Water Or Soup Every Time


Marijuana is tolerant of a wide range of pH levels. If you are growing in soil the pH of the water you use is usually irrelevant. Use decent tap water, and be more concerned about the high mineral content of hard water than pH levels. If you are growing hydroponically, pH is a much greater concern. Just keep in mind that the way most people arrive at damaging pH levels is by using products designed to increase or decrease pH.


#9 Improve The Taste By Watering Plants With Juice, Cool-aid Or Other Flavorful Liquids.


Unfortunately giving your marijuana plants OJ doesn’t make the buds taste like oranges.


#10 Skills Can Improve The Quality Of Buds


This is partially correct. Of course, your skills as a grower will have a significant impact on the quality of the harvest. But the genetics that grow with you are just as important.


There are countless types of cannabis, each with its own unique characteristics. If you plan to grow your own cannabis, regardless of the skills of the grower, it is especially important to invest in quality seeds from a professional seed bank. This is the only way to ensure that you really grow the top shelf buds.


If you want to grow marijuana indoor and need a cannabis Grow light, I recommend you buy from VANQ LED. The VANQ GLIC650 is an actual wattage 600W commercial-grade LED grow light tailor-made for commercial cannabis cultivation.
