7 Most Common Growing Myths
by Sirius Fourside

Some guy on an internet forum showed me a super-secret trick that he learned from his neighbor's cousin who is a master grower...

All you have to do is crumble 7 goldfish crackers per gallon of water into your nutrients every other feeding. The crackers use a wheat compound that’s impossible to obtain for non-commercial use, and this compound contains enzymes that make buds grow 40% larger!

Does that sound crazy? Good! Because it IS crazy!

One of the downsides to an invention as incredible as the internet is that crazy, nonsensical “tips” can easily be spread to thousands of new growers without any fact-checking. Unfortunately, many misleading tips just as crazy as this one not only exist, but are followed by inexperienced new growers!

That’s why today, we’re showing you the 7 myths we hear most commonly, and our verdict on their usefulness. Protect yourself against faux-info!
Myth #1 “You can tell the sex of your plant by looking at the seeds.”

Since only female cannabis plants produce buds, most growers are very interested in the gender of their plants! This means it would be incredibly convenient if there was a way to look at cannabis seeds and be able to definitively identify the gender. As appealing as that idea is, there just isn't a consistent way to visually identify the sex of cannabis seeds. Despite that fact, there is this persistent diagram that has been circulating the internet since at least 2008 and we get a few questions about it every year even though it's simply not true. 

This is Not an Effective Way to Identify Plant Gender! Growers Have Asked Us Regularly About This Misleading Diagram Since At Least 2008. Let's Put This Myth to Rest!
The main idea behind the "technique" is to look at the seed and identify characteristics that show the seed is female. However, it important to note that actual cannabis seeds don't attach in the same place as the seeds in the picture. In fact, those drawings probably aren't even cannabis seeds! 

Cannabis seeds don't actually attach to the plant at the place shown in the diagram. Compare the illustrations to real cannabis seeds below.
This technique for gender identification doesn't work for the vast majority of growers who try it. I have talked to one grower who told me they use this method on a regular basis, and he claimed that it works better than random guessing once you get some experience. But unfortunately, even he said the method has up to 70% accuracy in the best-case scenario. Those aren't good odds! That means about 1/3 of "female" seeds end up being male. It also creates false negatives, which means that about 1/3 of the "male" seeds you're throwing away are actually female...and those a best-case-scenario numbers!

The feminized seeds in the picture below all grew into female plants, but not one of them fits the description of a "female" seed from the diagram.
Did you know? The "tiger stripes" on cannabis seeds are actually part of a dark brown coating that can be easily rubbed off with your fingers. Seeds are tan underneath. 

Even if the technique from the diagram performed better than 50/50 guessing (it doesn't really seem to), it's definitely not a way to ensure that all plants you grow are going to be female. As far as we know, it's currently impossible to determine plant gender purely from looking at seeds.

The good news is, you can determine the sex of your plants by looking at their pre-flowers, which appear as early as 3 weeks from germination. They will have appeared on just about all plants by the time they're 6 weeks old, even if the plant is still in the vegetative stage! You can also start with feminized seeds from a reputable breeder, which guarantees that 99.9% of plants end up being female.

Due to recent advances in available technology, you can also test young cannabis seedlings for gender (when they're as young as 3 weeks old). You take a small piece of a leaf and send it in to a lab for identification. Learn How to Use Genetic Testing to Determine Gender of 3 Week Seedlings.

Myth #2 “You should urinate on your cannabis plants to give them extra nutrients.”
Don't pee on your plants!
Despite how bad this one sounds, urine does contain some nutrients plants can use, the most notable one being Nitrogen.

With that being said, don't do this. There are many cheap, effective, and readily available means of giving your plants Nitrogen without involving urine. 

A real cannabis nutrient system allows you to control exactly how much Nitrogen you’re giving your plant, so you give the right amount of nutrients at the right stage of life. More Nitrogen isn't always better, especially in the flowering stage.

Additionally, the amount of Nitrogen contained in urine changes depending on several factors and is extremely difficult to measure (who would want to anyway?). Peeing on plants may give them nutrient burn or a nitrogen toxicity, and sometimes may suffer from other nutrient deficiencies at the same time due to nutrient lock-out.

I don’t know about you, but nutrient burn due to urine seems much worse (psychologically) than the standard variety!
Myth #3 “You can grow weed in a [Insert Garden Gimmick].”
Many growers write into GrowWeedEasy.com to ask if growing weed in various garden gimmicks will actually work.

One common one is the Aerogarden. There are even growers who have written cannabis tutorials for it, and some swear by it as a cannabis growing method!

Weed can be successfully grown in an Aerogarden, that has already been established. But the reason the Aerogarden makes this list is due to the impracticality of growing weed in it.

An Aerogarden does save you from having to buy growing lights and a DWC (hydroponic) kit. But a better hydro kit would be cheaper, and the light provided isn’t strong enough to produce significant yields in the flowering stage. The lights are also way too close to the tops of plants, and the roots will overgrow the too-small reservoir in just a few weeks.

Another hydroponic option that's good for some plants and herbs but bad for cannabis is NFT (Nutrient Film Technique). These work best for small plants like lettuce. With cannabis, the plants at the bottom of the system often get nutrient deficiencies because plant roots are constricted and only get nutrient water after it's been used by several other plants. It's also common for plants to fall over and not be able to support their own weight.

NFT Systems Don't Work Well for Growing Cannabis
There are lots of better (and cheaper) ways to grow hydroponically that are much better suited to growing cannabis! Learn which methods are great for growing hydroponic cannabis.

It's a good idea to avoid most items that are intended for non-cannabis plants. For example, the "Topsy Turvy" is okay for tomatoes but causes upside-down cannabis plants to grow all the way around the outside to produce buds. Having to do that extra work may reduce overall yields compared to letting the plant grow out the top of a container.

The Topsy Turvy is designed for plants with hanging fruit, like tomatoes. It is not suitable for growing cannabis plants. Cannabis plants don't hang. Instead, they will constantly try to grow upward against gravity.
If the garden gimmick is made for herbs or other non-cannabis plants, it often isn't a great choice for cannabis! Before you invest your time or money in a particular product, take a moment to search Google or check online and see what results other growers are getting! 


 
Optimum Final Height for Cannabis Plants?

If you examine the structure of an indoor cannabis plant at harvest, you'll often see that there's long fat "colas" at the top, and underneath there are smaller buds. The further down you get on the plant, the smaller the buds are. After a certain point, the buds are so small that they don't really add any significant weight.
 This plant is the optimum height considering the setup and grow light. Why?

Look Who's Talking!


After 4 months I just harvested my first crop -- Wonder Woman and Aurora Indica seeds from Nirvana. WOW! I settled on a pretty standard setup: coco/perlite, 300W galaxyhydro LEDs in a 3x3x6 tent feeding with flora trio/calimagic/molasses. The results are excellent and I'm super stoked about the quality of the bud.

Truth be told, I didn't really expect to grow smokable pot. Just figured it was a fun little experiment and eventually the equipment would end up on craigslist. No way Jose. I definitely have the bug now and am already ramping up the next grow -- Blue Cheese and Chocolate Heaven, with more lights :)

Thank you SO MUCH for all of the information and guidance. Could not, would not, have done it without you.
