Inexpensive options include standard plastic pots or cloth bags, while some growers choose to spend more on “smart pots” or “air pots”—containers designed to enhance airflow to the plant’s root zone.
As your plants get bigger and especially when they start flowering, they’ll start to smell more. Outfitting your grow with a dehuey or AC can help bring odor down.
So when growing weed indoors, you can control the size of your plants by flipping them into flower whenever you think they’re big enough in the vegetative stage.
What size pot do I need?
For growers who have a little extra money to spend and want full control over their indoor garden, environmental controllers will allow you to automate the process. These devices are essential for if you’re away from the garden for a long period of time.
It’s also a good idea to have oscillating fans to provide a constant breeze in your grow room as it will strengthen your plants’ stems, making them stronger and healthier.
Unless you’re growing in a large, open space with a lot of ventilation, you’ll need air-cooled reflector hoods to mount your lamps in, as HID bulbs produce a lot of heat. This requires ducting and exhaust fans, which will increase your initial cost but make controlling temperature in your grow room much easier.
Proper air circulation will help maintain temperature and humidity, and also bring down odor. Ideally, air needs to move through a garden every few minutes, and you should create a vent to the outside. Oscillating fans, and intake and exhaust fans can move air through your garden quickly, taking odors out with them.
Another visual cue is the color on the bottom of the flowers. Buds cultivated outdoors almost always have a light brown color surrounding the stalk at the base of the bud (don’t worry it’s not mold). Usually, the tiny bracts at the bottom of the stalk will be a light brown as well. Indoor buds, on the other hand, are bright green (or purple) throughout.
Example of high trichome density on indoor cultivated buds.
One of the most significant visual characteristics that can be used to differentiate sun-grown cannabis versus indoor-grown cannabis is the color. Outdoor cannabis tends to have a darker hue in general. If the cultivar produces green flowers, outdoor nugs will appear a darker green, possibly leaning towards brown if not cured correctly, while indoor buds will be a brighter, more vivid green. If the cultivar produces purple flowers, outdoor buds will turn a deep, striking purple while indoor nugs will stay lighter shades of purple (unless the strain’s genetics produce dark purple buds in any condition).
Running through all these characteristics, with some give and take, while analyzing the hundreds of buds available for purchase at your local dispensary will help you to differentiate the outdoor grown from the indoor grown. If you are lucky enough to have access to the same flower cultivated both indoors and outdoors, it is amazing to smoke them side-by-side and compare the flavor profiles versus bag appeal. Indoor typically has better bag appeal while outdoor has the better flavor profile — it’s all about what you’re looking for in your daily smoke.
First let’s get a base calibration to see where you are starting.
If you don’t want to destroy it, you can continue to grow it separately from your other plants. That way you don’t loose the harvest (though it will be full of seeds), but the hermie plant also can’t pollinate the rest of your females.
Once your marijuana plant grows its first set of regular leaves (i.e. not the seedling leaves), it has officially entered the vegetative stage.
Once you have the space, you want to get it ready for growing marijuana indoors. The easiest way to do this is to get a grow tent. You can find tons of inexpensive tents on Amazon and these cheap tents are good enough for most of us.
Flowering Your Weed Plants
But if you buy from outside the country, the worst that will happen is that they are confiscated at customs. That’s it. You don’t even get put on a list. Then you just contact the seed bank and they will send you a replacement shipment (if it’s a good seed bank).
Once their roots have expanded throughout their new pot, it’s time to give them a larger one so they have room for growth. An easy way to tell they are ready to move is when the roots start coming out the drainage holes in the bottom of the pot.
Some growers like to give a full 24 hours of light, but I recommend going with a schedule of 18 hours on and 6 hours off.
This does depend on the strains, though. If the strain is labeled as short, you can expect it to not double in size during flowering. If it is labeled as tall, you can expect it to more than double in size.
