If you aren’t already growing your own cannabis at home, that might be due to one of the following misconceptions about constructing an indoor garden:

And we’ll prove it! Building your own climate-controlled indoor grow can be easy, convenient, and inexpensive all at the same time.

This guide will help you build from scratch three different garden setups at three different price points. Each build will contain all of the necessary components needed for climate control, and will not require any technical proficiency to assemble.

All of the hardware used for each project can be ordered on Amazon. This opens up the opportunity for just about anyone with internet access to order and discreetly receive the parts necessary for these builds.

First-time growers, budget growers, and those who wish to keep their garden as inconspicuous as possible are a good fit for the Nano Grow. At 24”x 24”, this tent is small enough to fit in most closets.



The Nano Grow is designed to be the most budget-friendly and least technical design. This build focuses on trimming down the necessary components to eliminate any superfluous items. While the essentials will cost you just over $100, you can add an optional inline fan and thermometer/hydrometer for just bit more.

LED lights work well in this environment because they produce very little heat. Although filtration for a grow of this size is not necessary, those who wish to grow in a more confined space should  consider opting for the intake fan and thermometer/hydrometer. This will help to both increase air circulation and provide some fundamental metrics for maintaining a healthy environment for the plants.

With the tent height maxing out at 48”, plants grown in this space should not exceed 24” in height and we recommend using dwarf, indica, and auto-flowering varieties for best results.

The Micro Grow is a value-driven package designed to provide all of the essentials for a single tent grow. More advanced than the Nano Grow, it’s a complete system that can handle just about any grow style.

This build is a perfect fit for a small room or garage space. At 64” tall, the tent affords enough room to propagate most smaller, bushier cultivars. There is a canopy height limit of between 35” and 42”.

In this setup, 2 to 4 plants are recommended. You can squeeze in 6 plants if you grow small auto-flowering varieties and/or vegetate the plants for less time.

Unlike the Nano Grow, this build contains a complete ventilation system designed to filter and exhaust hot air while simultaneously bringing in clean, cool air. Additionally, the timer has been upgraded to the dual-outlet digital model for controlling both the light and carbon filter exhaust system. A variable speed vent fan controller is also added for maximum climate control.

With the 315w CMH (ceramic metal halide) lights, enough heat is generated to recommend this build for an open space to allow for the best possible air circulation through the tent. The included 3100k bulb allows you to use the tent for both vegetative and flowering cycles.

Filtration setup: The 315w CMH generates enough heat to require filtration from the top of the tent. Airflow should be directed upward by installing the 6” duct booster fan at the bottom of the tent using duct tape and zip ties with the 4” carbon filter exhaust system at the top. Use heavy-duty zip ties to fasten the carbon filter at the back of the tent. Duct tape may be used to attach the fan to the filter as well as the filter to the aluminum ducting. Guide the ducting through the top port and fasten it with zip ties and duct tape.

With this system, cool air will enter through the bottom of the tent, and warm air will be scrubbed as it leaves the top of the tent. The 6” clip-on fan should be placed just above canopy level on the back-left pole to help circulate air evenly as the plants mature.

The Standard Grow offers a complete package for growers who wish to maintain a perpetual cultivation operation year-round. It covers all of the essentials in housing, lighting, automation, and filtration for a standard home grow.

No matter what your legal plant limit is, this tent should be able to handle it. At 80” for the main grow chamber, height is not a problem, and just about any cultivar can be propagated successfully under this build. With a 630w 3100k CMH fixture, this room can be used for both vegetative and flowering stages.

For growers who want a full system capable of germinating seedlings, taking and keeping clones, maintaining mother plants, and have multiple chambers for various projects, this is the build for you.

However, this system tends to run hot and will need the open air of a large room or garage to function optimally.

The “Standard Grow” is designed to be a fully comprehensive cannabis cultivation and propagation system, offering an all-inclusive perpetual grow space packed into a 4×5’ build. For just under $1,000, you get a 3-chambered, 3-light tent with a full air filtration system, automation and metering included.

This build allows growers to cultivate at multiple stages in the plant’s life cycle as well as provide housing for multiple propagation projects.

The 4×4’ main tent is powered by a 630w CMH light and the 1×4’ two-tiered tent extension is built out with two 4-bulb t5 fluorescent light fixtures. Complete with four fans, two dual outlet timers, and adjustable intake/exhaust components, this 80” tent supports even the most ambitious of grows.

Filtration setup: For the main room, fasten the first 6” booster fan to the bottom-left port of the tent with zip ties and duct tape, directing air inward. The second booster fan should be fastened in the same way on the top-left side of the tent above the first. This fan will direct air out of the tent.

The 6” exhaust kit may either be fastened on the top of the left tent or on the bottom-right, each option directing air through the carbon filter and out of the top port. This room receives two 6” clip-on fans—the first will be fastened to the top-right support beam of the tent to help move warm air towards the exhaust. The second fan can be placed on the back-left corner to follow the canopy as it rises.

For the second room, a 6” clip-on fan is fastened to the back-left support beam of each tier to direct airflow throughout each small chamber.

LMFO ! What about the cost of um, about what your gonna grow in those contraptions? That would be the purpose of this incomplete Gardening article.. Figure in around $100 per plant in soil or hydro at the least. IMO grow organic for the best medicine and good luck happy farmers.

I think that this is article is grossly underestimating the cost of an indoor grow. Now if you wanna grow outside, then under $100 be done with good soil, a pot for pot, and some sun.
