Soil: First and foremost, invest in top-quality soil as this will impact the entire growing process. Pick a nutrient-packed soil that contains organic substances like compost and worm castings. Pay attention to the pH levels of the soil as well — aim for a range of 5.8 to 6.3. Other qualities to look for in soil include good drainage ability, high oxygen levels, and effective water retention. You could also make your own super soil.

Once you have the best greenhouse for you, it’s time to put your cannabis cultivation skills to the test. Here are the most important aspects of growing top-quality weed in a greenhouse.

The ideal spot for your DIY grow room will be facing the sun. A slightly shaded area is fine, but make sure nothing is keeping the natural light from reaching your greenhouse. The more hours of light, the bigger the yield.
Lighting: A greenhouse gives cannabis plants the benefit of natural light without exposure to the harmful environmental stressors of outdoor grows. Using natural sunlight is energy efficient, so you can save money on electricity costs by not using artificial lighting.
The key word when it comes to growing cannabis in a greenhouse is control. Greenhouse cultivation provides the natural sunlight, fresh air, and other benefits of growing outdoors while eliminating the unpredictability of Mother Nature. Periods of rain and wind can wreak havoc on your weed garden, but a greenhouse protects plants from the elements. Likewise, pests, bacteria, and diseases are less likely to invade your plants in the shelter of a greenhouse.

That’s it! The above is a great option if you’re on a budget or lack the DIY skills to create something more sophisticated.
Adding the Walls
A greenhouse combines the large yield of outdoor growing with the control and security provided by indoor growing. In general, the average cost of one ranges from $7,000 to $28,000, according to Home Advisor.
