For a plant that’s so widely cultivated and consumed, cannabis can be a tricky to coax into full bloom, especially when growing at home. Myriad factors influence the final product: lighting, temperature, air circulation, nutrients, growing methods, and many more among them. This can be intimidating for beginner growers who want to get started but aren’t quite sure how. If tools and terms like TDS pens, NPK value, pH stability, and “nutrient burn” make you want to wilt, don’t worry – for one thing, you’re not alone, and for another, you can still grow cannabis indoors like a pro.
Episode 1: Choosing Your Setup
In the interest of providing a gateway for aspiring growers to plant their first cannabis crops, SuperCloset, which offers a variety of customizable and award-winning grow cabinets, hydroponic systems, and grow rooms to suit DIY growers’ needs, has developed a comprehensive series of instructional videos covering everything you need to know to grow. In these episodes of the Grow Like a SuperPro series, Rory will cover everything you need to know in order to set up your own indoor cannabis garden and make the most of your space as you get your seedlings started.
Episode 2: Germinating
Episode 2 introduces the steps of successful germination, breaking down the materials you’ll need to turn your seeds into cannabis sprouts. You’ll need a medium for the seeds, a pH testing kit, a TDS pen, a water basin, a seedling tray, a humidity dome, and a seedling heat mat. With your materials assembled, you’ll then learn how to alter the pH in your water supply to achieve stability, how to inspect your seeds and weed out the bad ones prior to planting, and how to ensure that your environment is actively encouraging seedling growth. In a few days, you’ll check back on the seeds to see how you’ve done.
Your plants may release more odor as they enter the flowering stage. At this point, you can further test odor neutralizers around your home, such as burning a candle in your living room or somewhere in the hallway. Although your closet may be tucked away in a more private part of your home, the odor may easily leak in the air.
#3 Setting up your grow medium
Your growing space needs to be clean. Closets, wardrobes or cupboards may often fall victims to negligence, hence there could be dirt or mold, especially if you are choosing a corner of your house that hasn’t been touched in years. So, ensure that your grow closet is well-cleaned. You can also paint the inside walls of the closet or blanket them with a reflective growing tent cover. That is, depending on how professional you want to go with your efforts.
#2 Installing your grow lights
Converting Your Closet Into a Grow Room
If you are a beginner, it’s best to stick with autoflowering seeds. Plants from autoflowering seeds are small and compact and they don’t exceed more than 3.2 feet (1 meter) in height. They also grow and flower quicker than other seeds. At all points of growing, combine 18 hours of light and six hours without lights to grow your closet autoflowers cannabis. Aside from controlling the size of your weed plant, you also need to contain any smell.
If you are growing weed in your closet, you also want to control the size as well as the odor that might be coming from it. First, it’s important that you select seeds that you know are not going to consume too much space as they begin to form into beautiful plants with flowers. Since you are growing in a closet, it’s easy to assume that your space is limited. If you are buying seeds from a local dispensary, ask the vendor for seeds that are optimal for growing in a small space.
If you are a starter and have no experience in growing weed whatsoever, you may want to stick with growing just one or a maximum of two plants. Having fewer plants means you are better able to observe the growing cycles of each plant and learn more from the process, plus it’s easier to discard your closet when you are done growing.
Mission Possible: Growing Weed in Your Closet
If you are growing a small number of plants it would help if you can circulate the air in the room where your grow closet is. Use fans and open the windows frequently. If you still notice a hint of a strange smell in the air, you can try to set up a small fan inside the closet.
Regardless of where you do your indoor growing, you can make use of the same grow medium options. If you are growing in soil containers, pay attention to how much water and nutrients you use for your cannabis plant. Overwatering and overfeeding are some of the most common growing mistakes that even experienced gardeners make. Too much water may cause the plant’s roots to decay, so treat your cannabis plant as you would treat a gentler flower.
You can also change the ratio during the flower period – so in early stages of flower, you can fine-tune your spectrum to minimize stretch.
How tall do cannabis plants grow?
Some newer models emit far-red and UV light, and can be precisely controlled to emit the exact percentages of each type of light.
This triggers the shade avoidance response and forces your plants to stretch.
In any case, now is the time to put your pruning and training skills to the test!
If nighttime temperature is the same as daytime temperature, stretch is reduced.
Later in flower (when your plants have truly stopped stretching), you should avoid creating a morning temperature dip, as you actually SHOULD create a positive day/night temperature difference (although not more than a 10°C/18°F difference, or you could cause excessive humidity and mold) in order to maximize cannabinoid and terpene production.
Airflow and Aroma
A four-pot Autopot system or similar with a 5-10 gallon tank would be ideal for a small closet grow.
