Some growers choose to estimate their yield based on the strength of their lamps. And while this is far from an exact science, it can be a bit more accurate than calculating your yield per plant, especially if you choose to grow multiple smaller plants, rather than just a few larger ones.
Ideally, you’ll want to grow in at least 18-litre pots. With this amount of soil, some decent nutrients, and some light pruning/training, you should be able to grow large, healthy plants that reach at least 90cm in height. Given they get a full 4–5 weeks of vegetative growth and solid lighting that penetrates right through to the lowest bud sites, plants of this size should be able to produce at least 100g of dry bud per plant.
Growing cannabis can be challenging, but there are plenty of things you can do to improve your yield as a novice grower. These include:
Remember, the weight of your buds will drop dramatically after drying and curing. So don’t get too excited when you weigh your buds right after trimming. Instead, multiply your wet yield by 0.25 to get a rough estimate of how much dry bud you’ll end up with.
While yields vary a lot, there are some ways you can get at least a rough estimate of how much weed you’ll produce.
Growing hydroponically gives you a lot more control over how your plants feed. With the right equipment and experience, this can greatly improve the size and quality of your yield. Experienced hydro growers, for example, can encourage yields of up to 1.2g per watt of lighting. By this logic—and using a 600W lamp—a good hydro grower can harvest over 700 grams of bud (genetics depending)!
• Read up on training techniques. Training your plants to grow a certain way maximises their exposure to light, which will ultimately improve your yield.
There are many different grow media out there, and they all have different effects on the overall yield of your plants.
Whether you grow indoors or outdoors will have a big impact on your plants.
