We’ve decided to write a full post on the exact materials needed to grow cannabis efficiently and affordably for all of the beginners out there that are a bit overwhelmed.
When you grow cannabis indoors the biggest giveaway is usually the intense aroma that cannabis plants let off during their flowering period. If you don’t want anyone calling the cops on you, we highly recommend installing an odor filter of some sort.
For your inline system to pull as strong as possible, your ducting will need to be as straight as possible. Every bend in your ducting system means that you’ll lose a bit of strength, around 50%, which can reduce your carbon filter and end up stinking up your building as well as being quite bad for your plants, providing them with less fresh air than they need to successfully grow.
Extraction fans are essential when growing cannabis indoors for two reasons. The first reason is that your plants need fresh air; they can’t sit in the same air for too long. All plants need certain levels of CO2 and Oxygen, which they use for different processes depending on the time of day (if it’s daylight or nighttime). The second reason is that if you don’t have an extraction fan, heat will build up in your grow room which is disastrous.
1.2×1.2×2 = 2.88 x 60 = 172.8m 3 . This is the strength that your extraction fan will have to reach to be as effective as possible.
Proper ventilation is incredibly important for plants to breathe, and an oscillating fan does wonders for rustling your plants’ leaves which induces breathing. If you grow plants with absolutely no fan or any sort of air movement in the room, your plants will grow super weak, as a slight breeze helps them to get stronger and hold up more flowers. Plants grown indoors without a fan are also more susceptible to insect and fungi infestations.
Before buying anything, the first thing you’ll need to do is figure out where you’re going to set it up. Are you using a full room, a wardrobe in your house, or a grow tent designed for cannabis growing? Depending on your chosen method, you’ll have to spend more or less money.
This calculation allows you to keep the temperature in your grow room at a 4C° difference compared to the outdoor temperature. If you’re taking in 20C° air, your grow room will stay at 24C°.
The yields mentioned above are the average numbers obtained under normal growing conditions. Professional growers can definitely harvest more than that, and beginners will most likely harvest less. When it comes to the lamp distance, this can also depend in the growing conditions and your plants’ health. These numbers are simply a guide.
The materials needed to grow cannabis indoors vary quite a lot; we've put together a list of 10 of the main things you will need to grow cannabis indoors.
Cannabis needs three macronutrients to grow: nitrogen (N), phosphorus (P), and potassium (K). Different nutrient formulas will carry these compounds in different concentrations. But beyond standard NPK formulas, you’ll also want to feed your plants micronutrients like calcium, sulphur, zinc, boron, manganese, copper, and iron. Give your plants a healthy combination of all of these nutrients, and you’ll be well on your way to producing some killer harvests.
• White Widow Automatic: White Widow is a world-renowned, classic Dutch strain. For this autoflowering variety, we crossed a potent, profit-yielding White Widow phenotype with a sturdy strain of _Cannabis ruderalis_. The result is a potent autoflower that goes from seed to harvest in just 8–9 weeks and produces great results regardless of your skill as a grower.
• Standard flower pots: Standard plastic flower pots are cheap, easy to get your hands on, and serve their purpose. For growers with a limited budget, simple 12l nursery pots are perfect.
To grow the best weed indoors, you need to have complete control over your plants’ environment. Two of the most important variables are temperature and humidity, so you’ll want to monitor both of these closely using a thermometer/hygrometer.
Remember, cannabis has different growing requirements than other plants. It likes slightly acidic soil with a pH of roughly 6–6.8 (5.5–6.5 for soilless grows). In terms of nutrients, cannabis needs varying concentrations of nitrogen, phosphorus, and potassium during its life cycle, as well as a rich balance of micronutrients like calcium, manganese, iron, copper, sulphur, and more.
• Royal Cookies: If you want to grow top-shelf US genetics at home, this is the perfect option. Royal Cookies was bred by crossing two unique Forum 1 phenotypes to create a super potent Cookies strain with up to 23% THC, capable of producing massive yields to suit. With a flowering time of just 8–9 weeks, this is a great intermediate strain that will produce some top-shelf bud every time.
• Miracle-Gro Potting Mix: Miracle-Gro is a well-established brand, and its Potting Mix is very popular among cannabis growers. It’s very well-suited for beginner growers as it contains all the nutrients your plants need in order to grow big and healthy. In fact, Miracle-Gro contains enough nutrients to feed plants for up to six months and promises to double your harvest without any extra work on your end.
Seedlings, for example, like high humidity levels of around 65–70%. During the vegetative growth phase, you can gradually lower humidity by 5% every week. In the final weeks of vegetative growth, the humidity in your grow room should sit at roughly 40%, which is where it should stay during flowering to avoid issues with mould and mildew.
Ensure you are aware of the laws of your country.
Are you daunted by the thought of setting up your indoor grow room? Don't be. Here's a checklist of everything you need to grow great weed indoors.
