How to grow different strains of weed

Some sativas can exhibit extreme stretching when they go into flowering, even tripling their height! Obviously, this can become a problem when space is limited. You will have to become good with training and bending your plants so that you can avoid massive sativas starving your other plants of light. Likewise, when it gets overcrowded in your grow room, this can also lead to other problems such as powdery mildew and mould, increasing the risk for pests in kind.

Let’s look into the pros first. After all, this is why you want to do it in the first place, right?

For a variety of reasons, many cannabis growers cultivate only one type of strain. Maybe you grow just one strain because you like its effect, aroma, and taste. When you grow several plants of the same strain, it means that your plants will require the same nutrients and watering regimen, and it ensures a fairly even canopy so that all your plants receive sufficient light for good yields. You can also expect to harvest your plants at about the same time. In short: If you grow only one type of weed, it can make things easier.

Growing a number of different strains will (likely) mean more work. Maybe you have experience growing indicas, but now you also want to grow a picky sativa lady along with it. Since both can vary greatly when it comes to watering and nutrient requirements, this can easily mean much more work since you now have cultivars that want to be treated quite differently.


If you have never grown multiple strains at the same time, we recommend that you start out with varieties of the same strain subspecies. For example, you could plant several types of indicas or hybrids. Even if you stick to strains of the same type, you can grow weed with different flavours, effects, and potencies without much trouble. The advantage here is that your plants will still grow quite similar, with only minute differences in growth pattern. Things will get a lot more complex if you want to grow sativas and indicas together, simply because these plants normally differ greatly in the way they grow and when they’re ready to harvest. So before you start, choose strains that you believe will grow somewhat harmoniously under the same roof.

You need to decide whether this one is really a disadvantage for you. Some growers prefer to harvest their crops all at once, which normally isn’t a problem if you grow the same strain. But if you grow quite different varieties, the harvest window for each plant can vary in weeks. Sativas take much longer for flowering as compared to indicas and most hybrids. If you still want to keep your harvest at about the same time, with maybe only a few days in between rather than weeks, then you should grow similar hybrids, making note of their flowering time before you plant your seeds.

Although this will depend on the strains you’re about to grow, growing multiple strains will often also result in increased yields. Here, it is important that you keep all your plants in a relatively flat shape (despite their differences) and that you aim for an even canopy. This is what can increase your indoor yields. If you grow different strains, but they are the same strain type, say only hybrids or indicas, maximising your grow so that all plants get about the same amount of light for an optimal harvest will be the best approach.


Growing different cannabis strains in the same room can provide you with nice perks. You can enjoy harvesting weed with different flavours and effects. It can also mean higher yields. But it can also pose some challenges. Here are the pros and cons of growing different strains in the same room.

No cannabis smoker is the same. There are those who love their indicas all day long, while others can’t get started in the morning without the kick from a sativa. Others still may swear by hybrids that give them the best of both worlds. But despite the preferences everyone has, there is really no reason to stick to just one type of weed, seeing that there is so much variation out there. In the worst case, you might be missing out on a really great strain just because you never tried it before. And well, unless you grow it, how would you know?

Most plants about doubled in size after the switch to 12/12, but this one in the corner tripled. It’s a good thing the grow tent was 6.5 feet (2m) tall.

When you have a lot of plants in a very limited space – like a grow tent with only a few feet in each direction – it can be easy to overgrow your tent without even noticing it.

A few weeks later, after some plant training and right before the switch to the flowering stage

Bend all the tallest stems over so they’re the same height as the other colas and plants, and secure in place. Just following that principle as your plants grow will give the shape you want

Minimize small height differences by using bending or moving tall plants to the edges to increase their distance from the grow light

A Tale of Two Strains (Indica vs Sativa)

How Strains Differ From Each Other

Each strain has different tendencies when it comes to overall growth speed and estimated height. Some strains grow tall and stretchy, while other strains grow short and bushy. Additionally, different individual plants of the same strain may grow differently from each other, especially if they come from seeds as opposed to clones (which are exact copies of each other).

Choose matching strains (same estimated height and flowering time) to help keep the grow space as uniform as possible
