Odor becomes much more difficult to manage in the final six weeks of a marijuana plant’s life, when trichomes and terpene production ramps up. You can also get odor-absorbing gels, which replace weed smells with other scents. Keep in mind that odor gels don’t eliminate odors, but simply mask them.

Fans are a must in a grow space to move air around, so buy some of those before an AC unit. If you find that fans aren’t bringing down the temperature enough, then you may want to invest in an AC.

You’ll need a dedicated space for your marijuana plants—you won’t be able to move them around. Ideally, the space is next to a window so you can vent air from the grow space outside. Growing weed plants smell! Especially when flowering kicks in, you’ll want to redirect air so your house doesn’t reek of weed.

The flowering stage will always take about eight weeks—some strains take seven, some nine, some even more, it depends on the strain.

Make sure air is circulating through your garden

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.

For most first-time gardeners, we recommend buying a quality potting soil that will provide your plants with enough nutrients to get them through most of their growth cycle without having to add many amendments or liquid nutrients. This pre-fertilized soil—often referred to as “super-soil”—that can grow cannabis plants from start to finish without any added nutrients if used correctly.

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.

Dehumidifiers and ACs

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.

There are many different media to choose from, including good ol’ fashioned pots full of soil, rockwool cubes, a hydroponic tray, and more.

Although there is a larger size MH/HPS grow light available (1000W), at that size it starts going outside the scope of a “hobbyist” grower as far as ease and yields. In addition to needing a lot of extra cooling, a 1000W HPS grow light is less efficient compared to a 600W grow light (as far as how much light is put out for electricity used). I think most hobbyist growers would be happier with a 600W, or even two 600W lights, over a 1000W.

Initial Setup Cost: $780.00

Average Yield: 5-10 oz Per Harvest

Medium Grow Setups

600W MH/HPS

Over the years we’ve had lots of people request “starter” shopping lists for new growers – it can be frustrating trying to figure out exactly what supplies you need to start growing cannabis indoors! So today I decided to make a few comprehensive shopping lists for common setups that include everything from nutrients to grow lights to rope ratchets. I’ll even tell you what yields, electricity cost and cost/ounce to expect with each setup.

Average Yield: 7-14 oz Per Harvest

Small Grow Setups

400W MH/HPS

I tried to include everything in these lists, as if someone were growing marijuana completely from scratch. For each example I calculated the cost as if you were buying everything online off of Amazon.com from the included links. A lot of these items cost less money if you shop around online or buy them in person, and you may already have some stuff lying around the house already.

Average Yield: 5-10 oz Per Harvest

After doing some simple math, you’ve reached a value of 3000W and now you know that, for example, if your light fixture consumes 400W and your exhaust fan 150W, it comes down to a total of 550W and the max wattage for that circuit is 3000W so everything should run smoothly.

To build a grow tent, you will need wood, metal or plastic poles, and a plastic sheet.

Unfortunately, you cannot make them at home (unless you have experience with electronics), so you’ll have to buy them.

Helps control humidity

The result of your DIY grow tent or grow box should be something similar to this:

The plastic sheet should be measured on the grow tent before cutting so you don’t have to redo it, make sure it doesn’t have holes to avoid light leaks and if it doesn’t get too hot where you live you can use 2 layers of the sheet to make the tent more resistant.

When growing cannabis, ventilation is super important; Having a proper grow room ventilation system will not only help you control humidity but also keep the temperatures down among other benefits, so for those of you who are thinking it’s not worth it to spend a couple of bucks, here are some other benefits that will make you change your mind:

3. Building your own indoor grow step-by-step

A grow tent is the best DIY grow space because (depending on how you build it) you can easily disassemble it when you need to and then mount it again without needing anything else.

After you have the structure mounted, you need to cut the plywood to start closing the sides of your grow box.
