The fact that cannabis seeds can vary in appearance has led some growers to think that the size, shape, or color of a seed dictates its quality.
If you are still unsure about the quality of your seeds after analysing their appearance and toughness, it’s time to put your lab coat and goggles on. Well, not quite. This test is extremely easy and only has two possible outcomes. Fill up a drinking glass or glass jar with water (preferably spring or distilled) and place your seeds on the surface.
Appearance And Feel – Checking The Color, Size, and Shape Of Your Seeds
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.
This is absolutely not true. As we explained earlier, cannabis seeds naturally look different, and no single physical trait of a seed can tell you whether that seed contains the genetics for a male or female plant. The only way to tell a female cannabis plant from a male is by looking at its flowers when it begins to sex. Don’t be fooled into throwing out perfectly healthy seeds just because a popular internet chart told you so.
It’s important to only conduct this test if you are planning to germinate the seeds immediately afterwards. The viable seeds that sunk to the bottom of the glass will have taken in water, crossing the membrane of the seed and signalling that it’s time to come to life—activating germination.
Because they grow and flower quicker, growers can fit in multiple autoflower cannabis harvests into the span of one regular harvest.
Immature seeds tend to be light in color and have a soft outer shell.
Tips for growing autoflower marijuana seeds
Many marijuana growers start autoflowers early in the season, and at a different time than a regular crop, so keep the season and climate in mind when growing and harvesting—your plants still need warmth to grow, and rain can give them bud rot. Consider growing in a greenhouse to protect them.
Aside from producing cannabis through seeds, or sexual reproduction, you can also reproduce the plant through cloning, or asexual reproduction. A clone is a cutting that is genetically identical to the plant it was taken from—that plant is known as the “mother.”
If you’re ready for a more serious approach, make sure you have the space for a proper garden and pop the seeds to see what fruit they bear.
A well ripened cannabis seed had sufficient time for hardening its shell. Healthy cannabis seeds are therefore provided with a hard smooth skin without cracks. You can test the hardness of the shell by taking the seed between your fingers and applying gentle pressure. Immature seeds will easily crack or crumble while qualitative cannabis seeds won’t damage.
Although it isn’t always visible with the blind eye, on a quality cannabis seed you can see a pattern of “tiger stripes” or dark spots.
Cannabis seeds have a unique shape. They are oval, have the shape of a drop and are small in size. On average, a cannabis seed is about 2 to 5 mm long and 2 to 3 mm thick. If you want to know what you can expect in advance, then we can advise you to take a look at the seeds of a tomato.
Shape and size of a cannabis seed
Fertile cannabis seeds are black, dark brown, red-brown or gray with a shiny glow as if there is a bit of wax on the peel. Cannabis seeds with a different color such as white, yellow or light green will probably also germinate, but indicate lesser quality. Such seeds have been harvested too early and haven’t had enough time to ripen.
The quality of a seed can be partially assessed by looking at the appearance. However, you have to know what a healthy cannabis seed looks like and that can be difficult. Even for the experienced grower. In this blog we therefore answer various questions such as: what do weed seeds look like and how can you see if a cannabis seed is healthy and viable?
Healthy cannabis seeds are sufficiently matured and therefore have a different appearance than unripened cannabis seeds. For example, viable cannabis seeds meet a number of criteria. Think of the size and shape, hardness of the outside and color.
Note: this test isn’t 100% accurate and only provides an indication of the viability. In addition, the water will activate the germination process. Therefore, only carry out this test if you want to germinate the seed immediately. After performing the float test, you can’t longer store the seed.
