You’ll need to ensure that temperatures remain within a comfortable range for your plants, between 70-85°F when lights are on and between 58-70°F when off. Some varieties of cannabis—generally indicas—prefer the colder side of the range, while others—typically sativas—are more tolerant of high temperatures.

Remember, a common mistake newbie growers make is to overwater plants.
Tools to measure temperature and humidity.
Terra cotta pots offer a unique set of benefits to growers in hot climates.
Here are some ways to mitigate odor when growing weed indoors.
When growing weed indoors, you’ll likely have to add nutrients to your plants. You won’t need to add nutrients every time you water, but get on a schedule where you water every other time, or two on, one off.
Different lights produce different colors of light. Here’s a brief rundown of the most popular types of cannabis grow lights used for indoor growing.
Although you’ll be controlling the climate inside the grow space, climate outside the grow space will affect your plants. If the environment outside your grow space is very warm or humid, you’ll have issues controlling your grow space. Choose a cool, dry area with ready access to fresh air from outside.
One trick to avoid hot temps is to have the grow lights on during the evening, when it’s cooler outside, and leave the lights off during the day when it’s hot. This may help bring down the temps, but you’ll only be able to work on the plants at nighttime when the lights are on.
Fluorescent light fixtures, particularly those using high-output T5 bulbs, are quite popular with small-scale cannabis growers because:
LED grow lights.
That’s a big variance, but it really depends on how big you want your plants and how often you want to harvest—you can have multiple harvests of smaller plants, or less harvests of bigger plants.
In addition to bulbs, HID lighting setups require a ballast and hood/reflector for each light. Some ballasts are designed for use with either MH or HPS lamps, while many newer designs will run both.
Every space is different and there will be a learning curve to growing in yours.
Plants need fresh air to thrive and carbon dioxide (CO2) is essential to the process of photosynthesis. This means you will need a steady stream of air flowing through your grow room, which will allow you to move hot air out of the space and bring cool air in.
Generally speaking, it takes anywhere from 10-32 weeks, or about 3-8 months, to smoke what you’ve grown. (It’ll be quicker if you start with a clone or an autoflower seed.)
Watering and nutrients.
These come in different shapes and sizes and are a great way to get rid of odor in an indoor weed grow. Also known as “carbon scrubbers” for their ability to get contaminants out of the air, these employ activated and highly ionized carbon to attract particulates responsible for carrying odor, such as dust, hair, mold spores, and volatile organic compounds, and traps them in a filter.
The biggest variability in how long a marijuana plant takes to grow will happen in the vegetative stage—after the seedling phase and before flower.
When designing your space, you’ll need to take into account room for your plants, as well as space for lights, fans, ducting, and other equipment. You’ll also need space to work on the plants. Cannabis plants can double in size in the early stages of flowering, so make sure you have adequate head space!
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.
For small spaces or tents, clip-on fans can be attached to structures like walls, corners, or support beams. For larger grow rooms, use medium-sized oscillating fans or big floor models.
Carbon filters usually work best when positioned at the highest point in your grow space, where the most heat accumulates.
Next was the Gorilla Glue Auto plant. I’ve never been happy with this strain and I wouldn’t recommend it. Bud effects and smell are good, but plants grow weird and buds are ugly and airy. Two other examples of Gorilla Glue Auto plants I grew for comparison.
For example, these autoflowering plants are bushy and short because I trained them to grow in that shape (starting when they were just 3 weeks old). This bushy shape forces cannabis plants to grow many bud sites as opposed to just one main bud site at the top of the “Christmas tree”.
Plant pots are usually sold as a set online, but garden stores sell individual pots. Or DIY your own pot for free!
$5/grow to replace HPS bulb – The 150W HPS bulb needs to be replaced every 3-4 grows as they begin to lose brightness over time (not applicable if using an LED grow light) – $15 for a new bulb every 3 grows, or.
You’ve already got some of your growing supplies, so your second grow will be cheaper than the first one.
4.) Flowering Stage – Buds Start Growing!
You got this! Even if you follow just 80% of the directions in this tutorial, if you can keep your plant alive you should easily be able to yield at least 1 ounce!
As time goes on, your costs go down while your yields go up.
My recommended strains start at.
The total yield under the HLG 100 was 156.12 grams or about 5.5 ounces.
Your plants need a place to put their roots. You have lots of different grow medium options for growing weed, and the most common is good old-fashioned soil.
There’s nothing wrong with letting plants grow naturally, especially for your first few grows. But if you plan to keep growing inside under grow lights, plant training is important to achieving the best yields.
If you see pollen sacs (look like bunches of pointy grapes), remove the plant immediately from the grow area. Why?
Example yield from 150W HPS – 2 Autoflowering Plants – 3.5 oz.
Most cannabis plants naturally grow in a “Christmas tree” shape in the vegetative stage unless you take action to change it.
It’s hard to beat the convenience of a grow tent. While not necessary to success, grow tents can be put anywhere for an instant “pop-up” waterproof grow space that helps contain heat, light, and smells. Also great for keeping multiple grow spaces at the same time.
Seeds or clones – Starting at $30 for 3 seeds.
Another bud that’s ready to harvest. Notice how most of the hairs have darkened and curled in.
Future grows: As little as $48/harvest (for electricity, nutrients, mixing your own coco/perlite mix, and a new HPS bulb every few grows) – only $34/harvest if using the suggested LED grow light (it uses less electricity and you don’t have to replace any bulbs).
If you started with auto-flowering seeds…
If you’re buying new seeds every grow, it becomes an ongoing cost. Buying seeds can get expensive! If you stick to auto-flowering strains, you’ll probably have to buy seeds every new grow. However, after your first grow, you’ll have experience under your belt and be prepared to grow photoperiod strains. Initiating the flowering stage can be a little trickier but overall care is basically the same. Photoperiod plants give you the ability to take clones, which is the easiest source of basically free plants. Another way to get basically free plants is to breed your own seeds or even make your own feminized seeds at home.
Choose autoflowering feminized seeds from a trustworthy breeder to ensure every plant grows buds and is ready to harvest in under 90 days. This Cinderella Jack Auto by Dutch Passion produced many dense potent buds and was harvested 79 days from germination.
Possible upgrades for your grow environment (all are optional but nice)
If you’re starting with soil, you may be able to avoid using nutrients at all. Yet if plants use up the nutrients in the soil you’ll start seeing nutrient deficiencies and slow growth. To help ensure the best yields and bud quality, I recommend you get at least a Bloom nutrient (low in Nitrogen and high in Phosphorus/Potassium) for plants that are actively growing buds.
Grow light – Starting at $70.
This is the stage where plants start growing buds. It’s exciting! You’re getting closer to harvest every day.
The average cost of electricity in the USA is Total Cost of 1st Grow: $135 plus $10/month electricity (as little as $20/grow for supplies after that).12/kWh. At 18 hours/day, that’s an electricity cost of about $10/month for the 150W HPS, and $7/month for the HLG 100.
Here’s an overview of all the supplies you need to start growing cannabis via this method:
Other differences after first grow.
Your plants will only grow stems and leaves at first. In the vegetative stage, plants keep getting bigger but don’t grow any buds.
Main upgrades: A grow tent, carbon filter, and exhaust fan to contain light and smell.
This $70 grow light can produce up to 5 oz (average of 2-4 oz)
