s alcohol may completely disappear from the body in just a few hours. In comparison, weed lingers much longer.
Drug tests can detect tetrahydrocannabinol, or THC, in urine, blood, and hair for many days after use, while saliva tests can only detect THC for a few hours. This is because of the way the body metabolizes THC.
THC is a lipid-soluble chemical. This means that it binds to fat in the body, which increases the length of time it takes for someone to eliminate THC completely.
Research on the amount of time a test can detect marijuana shows a wide range of averages. Research from 2017 estimates a detection window for a single marijuana cigarette of about 3 days.
The same study emphasizes that detection windows vary and depend on how often a person smokes.
For someone smoking marijuana for the first time, tests may detect it for about 3 days.
In someone who smokes marijuana three or four times per week, the detection window is 5–7 days.
For people who smoke marijuana once a day or more, tests may detect it in their system for 30 days or longer.
Detection windows also depend on the kind of test a person undertakes. General estimates for various marijuana tests are as follows:
Urine tests can detect marijuana in the urine for approximately 3–30 days after use.
Saliva tests can detect marijuana for approximately 24 hours after use. Some saliva tests have detected marijuana for up to 72 hours.
Hair tests are the most sensitive tests, detecting THC for up to 90 days after use. However, these tests are testing the oil in skin that transfers to hair, and so they may occasionally show a false positive. A person who comes into contact with a THC user could, theoretically, test positive on a hair test.
Blood tests can only detect THC for 3–4 hours.
Where Is Cannabis(Marijuana) Legal?
Step 1: Find a Place to Grow
Growing indoors is much more private than growing outdoors and you also get more control over your growth.
Indoor canabis grow can be surprisingly cheap to get started and maintain, especially if you plan on growing just a few plants.
You have more control over everything in an indoor growing environment, which means that indoor growers can consistently produce dank buds. However, this dank weed-growing power comes with more responsibility. As an indoor grower, your plants are 100% reliant on you your care if they are to survive. If you don’t provide everything your plants need, they will die.
What space works best?
You can grow canabis almost anywhere that has easy access to water and fresh air…
a spare room
even the inside of a computer case!
I recommend a Space Bucket instead when thinking about where to grow indoors, you should also consider the temperature (also referred to as ‘temps’) of your grow space and remember your temps will rise once you have your grow lights running!.
A thermometer - Temperature is important when growing canabis indoors. Young growing cannabis plants grow fastest when temps a bit warmer, in the 70-85°F (20-30°C) range.
When plants are a bit older, in the budding/flowering stage, it’s best to keep temps slightly cooler, around 65-80°F (18-26°C) to produce buds with the best color, trichome production, and smell.
Because temps are so important, it’s best to be able to have some amount of control over the temperature of your grow area. When growing indoors, your grow lights will give off heat. Generally, the more powerful your lights, the more heat they give off.
If you want to install a lot of bright lights in a small space, you will likely have to install an air conditioner in addition to your exhaust system to make sure you keep your temps in the right range.
If you’re growing just a few plants in a grow tent or box, usually you can install a fan to pull hot air away from the hot lights and out a window to keep things cool enough.
Some lights tend to cause more heat than others, and we’ll help you find the right lights for your space in Step 2.
Step 2: Choose Your Light
LEDs are much more powerful than CFLs or any other fluorescent lighting. They are top-tier grow lights on par with HID l
