Without proper airflow, a grow space can experience rapid changes in humidity or develop pockets of CO2 depletion, neither of which are good for plant growth. CO2 depletion can lead to nutrient lockout, and areas of high humidity are prone to pest infestation, mold, or mildew.
It can be tricky getting the right balance of temperature and humidity because they affect each other—turning up your dehumidifier will lower the humidity of your grow space, but it will also increase the temperature of the area. This in turn may require you to turn on an AC unit—everything’s connected!
Below is a list of things to consider and equipment you will need to purchase to get started growing marijuana indoors.
Good soil for cannabis relies on a healthy population of mycorrhizae and soil bacteria to facilitate the conversion of organic matter into nutrients that a plant can use. Alternately, you can use a regular soil mix and then supplement your plants with liquid nutrients.
Many homegrowers use 4’ x 4’ tents for the flower cycle. That said, I personally prefer the 5’ x 5’x 6’8” CLOUDLAB 866 by AC Infinity ($189.99). The extra space promotes plant health and lets me hang side lighting just below the top of the canopy for a boost in yield.
While I would like to see zipper covers to protect against light leaks, the balance of high-end features and affordability makes for one of the best value buys on the market and one of the nicest tents I’ve used, period.
It does have a hefty price tag, but it’s a great kit if you don’t want to think about all the pieces involved in setting up a grow.
For most cultivation setups, a room where a human would be comfortable in a t-shirt is perfect.
But benefits aren’t limited to yield. Grow tents are outfitted with fan ports to swap hot, CO2-depleted air for a neutral, fresh breeze, improving a grower’s chances of raising healthy plants. Additionally, by limiting the size of a grow space, filtered exhaust fans scrub the air using far less electricity than they would in an open room—thereby minimizing a garden’s overall power consumption.
Best flowering & all-purpose grow tents
Flowering tents are taller and wider than those intended solely for growing plants in the vegetative phase. During the first two weeks of the flowering cycle, plants will double or even triple in size depending on the cultivar and environmental conditions. Growers give themselves as much wiggle room as possible for this phase, known as “the stretch.”
Homegrowers have flocked to grow tents for decades to minimize an indoor garden’s impact on a house while sequestering aromas, promoting plant health, and maximizing yields.
Additionally, each grow will cost about $150 in nutrient cartridges and carbon filter refills. However, co-founder and CEO Yoni Ofir said that eventually the company hopes to drop the price of the actual device and generate its primary revenue from refills (à la Keurig).
Leaf, a TechCrunch Disrupt SF 2015 Battlefield company, is leading the revolution with its automated “Plug N’ Plant” home growing system. Leaf’s device is a 4′ x 2′ box that will fit two plants, which will yield between 4-5 ounces of weed.
Today, the company is opening up preorders of its device. Leaf will be available to users with a medicinal card in any of the 23 states that allow medical marijuana, as well as in the four states where marijuana is currently legal.
This is all controlled from Leaf’s iPhone app, which will also serve as a social network for users to exchange recipes and share videos of their plants.
However, Leaf is much more than just a mini grow house. The system will monitor everything that your plants need to grow, including light, ventilation, nutrient levels and pH of the soil.
The system will also react to these measurements, meaning that if it senses that your plants are low on nutrients it can dispense more, or if it needs more light it can automatically brighten the environment. Users can also control these variables manually, effectively creating their own grow “recipes.”
However, as is the case with most new industries, slow regulation hasn’t stopped innovation.
Leaf has received a strategic investment from Advanced Nutrients, a major player in the cannabis nutrient space. The company will be supplying Leaf with nutrients that they will put inside individual, disposable pods, allowing nutrients to be replaced like an ink cartridge in a printer.
However, this technology comes at a cost. The device will retail for $1,499, which makes it much more expensive than simply growing your plant in the ground. However, the company says that the machine will technically pay for itself after just a few months, as the “retail value” of 4-5 ounces (one growth cycle) is around $1,200.
