When the grow room is 4 x 4 x 8 feet with a 600-watt HPS lamp, expect to get 5.0 to 10 ounces of weed. Advanced growers can easily get 21 ounces.

Not surprisingly, using high-quality soil and fertilizer will also lead to bigger yields. As we can see, many variables can affect both the quantity and quality of the weed we can harvest. Therefore, we will focus on them to get the nearest estimate of the yield.
Expect to get lesser yield in soil since it acts as a buffer to the nutrients, making the absorption rate much slower. The maximum yield is 1 gram per watt, which means that 600 watts of HPS lamp will produce 600 grams or 21 ounces of weed.
While getting this kind of yield seems exciting, it takes a lot of pruning and longer vegetative time. Also, in the unfortunate moment that it gets sick, we will be left with no replacement.

On the other hand, a 3.5 x 3.5 x 7-foot space and a 400-watt HPS will provide 4.5 to 9.0 ounces of weed. But for advanced growers, the yield is 14 ounces.
Now that we know how much weed to expect in one plant, let’s learn how to boost the yield.
Under perfect conditions, an outdoor marijuana plant can make up to 500 grams or 17.5 oz of weed. As mentioned, ample space is vital for the plants to flourish. This means that each plant must have at least 2 meters or 50 liters of soil in a container.
The overall yield of the crop is the top priority of marijuana growers. To get maximum results, know exactly how much weed to expect in one cannabis plant.
Nutrients – The number of nutrients you feed a cannabis plant can as much as double an average pot plant yield. Proper nutrients when using soil are established by either creating a super soilor using a fertilizer. The most effective and least strenuous on a marijuana plant is fertilizer that is present in the dirt before the plant is even established.
Temperature – The temperature and moisture in your grow room will also aid a cannabis plant in producing not only more substantial amounts but even more important, more potent buds. You should always maintain an average of 24 C to 26 C with a humidity level that hovers just above 50% for optimal results.
Lighting – An experienced grower should expect to see approximately one gram of dried weed for every watt your light produces. As an example, a seasoned grower should be able to produce 600 grams using only a 600-watt light. They key to getting the most out of an indoor grow room is adding as much light as possible.
Room to grow – Marijuana plants will require a sufficient amount of space to grow in. If any of your plant’s leaves are touching walls or light fixtures than your average pot plant yield will suffer for it, not only will it not be able to stretch out, but it will be impossible for the entire plant to receive sufficient light as walls that are too close create unnecessary shadows.
How Much Can You Harvest from One Weed Plant That Is Grown Indoors?
Average pot plant yield in grams
Air quality – Cannabis plants thrive on higher levels of CO2. To reproduce this, you will need to have sufficient air exchanging that will be consistently drawing in air from outside.
Your average pot plant yield is going to depend on several determining factors. The most significant contributing factors will be the strain you choose to grow and the environment in which it will live in. However, the average pot plant yield is usually between 150 and 300 grams of dried weed. To more specifically determine your crop’s potential, we will focus solely on indoor growing methods, requirements, and average yields.
There are some pretty significant discrepancies between the lowest and highest average yields that should be expected. Lower estimates are geared more towards inexperienced growers, and higher ones can be produced by seasoned growers. The general rule here is that you should never have more than four plants per light and that your fixtures and the square footage of your grow room are both essential parts of producing the highest yield possible.
Your average pot plant's yield is going to depend on several factors. The most significant being whether the strain you choose to grow and its environment.
