You can achieve almost any size or shape when growing indoors as long as you use plant training. But if a cannabis plant is left to grow outside with tons of sun and without any plant training, the sky is the limit for how big they can get!
In response to the need for more tutorials aimed at new growers, Nebula co-founded GrowWeedEasy.com in 2010 with fellow grower Sirius Fourside.
Although it isn't the be-all end-all when it comes to size, strain is still definitely something to keep in mind when it comes to height. Although you can control the exact height and shape of your plant no matter what the strain with plant training, different strains grow differently and you want a strain that makes it easier to get the results you want. When growing with bagseed (seeds that you find in your buds) you often don't know what to expect until the plant actually starts growing.
Growing Method – soil tends to be the slowest growing medium, and hydro tends to create the fastest growth
But that's a huge range, right?
These plants were trained using manifolding. They were about 5 feet tall at harvest, and produced more than a pound of bud!
This is especially true for indoor growers, where you are in charge of nearly everything. When growing outdoors, you still have a bit of control over plant height, but you are also at the mercy of the sun and the elements.
A: Most plants are ready to harvest after 65 to 70 days of flowering. A good way to tell if the plant is harvestable is to get a 45x magnifying glass from a grow store and check out the trichomes on the flowers. Trichomes are the translucent resin glands that contain the cannabinoids. When they turn amber or a milky purple, you know they’re ready. This sounds difficult, but it’s actually pretty easy for the layman to do.
Kayvan Khalatbari is operations head of Denver Relief, a marijuana-growing dispensary and consulting business, where every plant is tracked througout its growing life.
A: All sorts of prepackaged items are available, like grow boxes or grow tents, that are probably best for a small space like a closet, or fo r someone who doesn’t want to get into growing marijuana too intensely.

An overview of the basics
Q:How are the plants fed and watered?
Q:How would a home grower comply with the rule that limits them to three plants in flower?
A: When a plant is fully mature, some people cut it off at the base, then cut off the fan leaves and hang it upside down. After it’s dried, they’ll trim off all the outer “sugar” leaves (the single leaves close to the bud).
A: Many people use 5-gallon plastic buckets, but those create problems because the roots just wrap around themselves and form a large root ball. If you use a 3- to 5-gallon fiber pot, the root sticks through the pot and (the plant) air-prunes itself, while feeder roots grow in the pot. That gives the plant a larger nutrient intake.
This was the longest solid cola I’ve gotten from a 250W HPS grow light; it was about 12″ long. Below that point, the plant still made buds, but they were individual buds as opposed to a long cola. The final height of a plant should generally be about twice the height of your longest main cola. That tends to be the “sweet spot” for a lot of strains.
Optimal Plant Height Depends on Your Grow Light. Bigger Lights Can Support Bigger Plants and Longer Buds!
In this example, the plant was “lollipopped” (the lower part of the plant was stripped of leaves and bud sites before being switched to the flowering stage). However, on the parts of the plant that weren’t stripped, you can see significant buds going a lot further down. This plant likely would have yielded even more if it’d been allowed to keep more bud sites. The grower could have still stripped all the leaves, but they may have gotten better results if they’d left bud sites for at least a few more inches if not all the way to the bottom.
So What’s the Best Plant Height?
Note: Defoliation (removing leaves to expose bud sites) lets you produce bigger buds further down into the plant! That means your light could potentially support slightly taller plants with longer buds if you use defoliation. This is why it’s important to always test your plants with your light and your setup, as everyone’s results will be a little different based on their strain, environment and personal growing techniques.
