how viable are split cannabis seeds

Splitting is a really aggressive high-stress technique, and we only recommend it to experienced growers. Also, we do not recommend stem splitting on autoflowering strains, as it can be far too intense for them.

1. First, start by measuring the part of your plant’s stem that you’ll be splitting. You’ll want to make a cut of around 10–20cm right beneath the lowest branches of your plant. Use some tape or rope to mark out both the top and bottom of the cut.

3. Use your knife to cut down to the lower mark you made earlier. Make sure your cut is as straight as possible. Once you reach the bottom of your cut, keep the knife stuck in the stem and use a pencil/chopstick/skewer to pry open the cut, then pull out your knife.

WHAT ARE THE RISKS OF STEM SPLITTING?

Stem splitting is a very aggressive grow technique that’s generating a lot of discussion in the cannabis cultivation community. Those in favour of this technique argue that it stresses the plant in a beneficial way, forcing it to take up more nutrients and produce bigger, more potent buds. Could this be true? Keep reading to find out.

The theory behind stem splitting is no different. However, it’s a lot more controversial than other high-stress techniques such as topping, fimming, or super cropping. After all, taking a knife to the stems of your flowering cannabis plants is pretty hardcore.

There are many different theories on the best time to put scalpel to stem, but most growers suggest doing so in the last week of flowering. While some growers recommend splitting in the last 3 days before harvest, we recommend slightly earlier (7–10 days before harvest).

2. Next, take your knife and cut through the stem, starting at the highest part of the cut. Be sure to make a clean cut right through the centre of the stem.

Unlike other agricultural crops (like vegetables, fruit, or grain), cannabis hasn’t undergone the vigorous breeding techniques that ensure a stable crop. This means that you’ll sometimes sow a pack of seeds technically labeled as the same “strain,” but may end up with very different looking plants. It also means that the individual seeds you buy from a seed bank can vary in appearance.

The alternative to this is to risk buying seeds from a hobbyist. This isn’t to say that hobby growers cannot produce fantastic genetics, but if you don’t know them or their skills, there’s no way to know whether your seeds will grow.

Appearance And Feel – Checking The Color, Size, and Shape Of Your Seeds

A quick web search will bring up all kinds of myths about how to tell female cannabis seeds from males. One of the most popular ones comes from a chart showing 5 different seeds that claims that the female seeds have “a perfectly round volcano-like depression at the bottom (from where the seed was attached to the plant).”

A solid way to obtain great seeds is to find a reputable seed bank. These companies pride themselves of their breeding skills and make sure that their customers receive exactly what has been advertised. They have reputations to cater to, so delivering anything less would only harm their image.

Keep in mind that the simple process of packaging and storing cannabis seeds can also affect their appearance. Abrupt changes in humidity, temperature, or light exposure can make some seeds appear darker or lighter than others, but ultimately have no effect on their quality.
