Highest Yielding Strains in 2020: 10 Best Cannabis Strains for Growing


For pretty much every cannabis grower worth their salt, quality is going to be more important than quantity. We grow and consume weed because we love the bud’s rich aroma, the perfectly chilled or intense highs, and the knowledge that we produced something beautiful.

However, there are some strains of weed where you don’t have to sacrifice quantity for quality. Depending on the seeds and your growing techniques, some strains will still deliver you an impressive yield without compromising any of the good stuff we love about the plant.

What to Look for When Buying the Highest Yielding Strains – Buyer’s Guide

There’s a lot to bear in mind when buying marijuana seeds for a high-yielding plant. You want to be sure to master the process of cultivating these seeds to their full potential. Individual strains need particular conditions and care to achieve that maximum yield you’re seeking.

Here’s a summary for novice seed buyers on what to bear in mind when buying the highest yielding strains:

Harvest Time

Patience is critical when taking advantage of a high-yielding marijuana strain. Certain strains will reach a flowering stage sooner than others. If your objective is harvesting as much as possible, bear in mind that some seeds will reach this stage sooner than others.

Also, remember that some strains may give the impression that they are ready for harvesting when, in fact, giving them another week will deliver more bud. Do some research on each strain’s particulars when it comes to this aspect of cultivation. There’s a wealth of information online on this topic. Doing this research before you choose a particular strain will also be helpful since you may be cultivating under time constraints.


For maximum yields, plants need additional nutrients, regardless of whether they are being grown indoors or outdoors. It stands to reason that plants with higher yields need more energy than plants that produce fewer (or less dense) flowers.

When choosing a strain, you must understand the plant’s nutritional needs. You may live in an area with soil that provides some specific nutrients, or you may have limited access to other types of nutrients.

When cultivating outdoors, it is extremely important to understand what a strain’s nutritional needs are and to compare these against the soil you’re going to plant your seeds in.

If you’re planning on growing indoors, a strain’s nutritional needs still matter. However, you can circumvent some issues by purchasing soil custom-produced for your needs.

Again, researching your strain’s requirements from this perspective and choosing an appropriate soil is a vital part of achieving maximum yields.


Since marijuana plants produce buds once they start receiving less light, the control of light is critical if you want to maximize your plants’ output.

Outdoor growers have less control over the light their plants receive, but it bears mentioning that if you are a novice grower and you do not have the option to grow indoors, give a lot of thought to your strain’s requirements from this perspective.

Some seeds are even Autoflowering, meaning that they will not need natural changes in light or light manipulation to flower. If you’re facing constraints in the light-department, these strains are an excellent choice.

If you do have many outdoor locations with different light qualities available, have a good look at each strain’s light requirements before choosing one or deciding where to plant it.

When growing indoors, the process is somewhat easier, but your strain’s light needs remain essential. Don’t assume that you can take a one-approach-suits-all route when you have the luxury of manipulating light. Research each strain’s light requirements and choose one that suits your ability to manage the light.

Final Thoughts

Investing in a strain that is known for delivering high yields is the right decision whether you are planning to consume, share, or sell your harvest.

The strains on this list – all of which yield a large number of buds – are also relatively easy to grow and are typically extremely hardy. In some cases, pruning or staking is necessary, but the majority of these plants will thrive with minimum effort.
