how small are marijuana seeds

However, slight patience is required when conducting the float test, as results are not immediately apparent. You’ll have to wait for approximately 1–2 hours before confirming the results. Some good-quality seeds will need adequate time to absorb enough water for them to sink. Use this time to go water the garden and get some much needed pruning done. Upon your return, any seeds that remain on the surface are most likely not viable and won’t be worth further time and effort.

The one true method to test the genetic potential of a seed is to simply put it in the soil. It won’t take too long to see the results. This option is best for the hobby home grower who has time and space to spare for a risky project. Growers cultivating cannabis for commercial use likely don’t have the excess time to invest.

Immature cannabis seeds, on the other hand, tend to be green and have a soft outer shell that breaks when any kind of pressure is applied to it.

Conducting The Float Test

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.

We do not recommend taking the size or shape of a seed into consideration as a sign of its quality. Some strains simply produce smaller seeds than others, and sometimes the same plant can produce seeds of different sizes and shapes. Never discard a seed just because it is smaller or of a different shape than another one.

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 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.

As most of the cannabis varieties that are currently on the market are polyhybrids, the size of the seeds can vary depending on their genetic line.

Another aspect that can be misleading is the fact that a ripe, freshly-harvested cannabis seed has a brighter and darker colour than after it’s been packaged for 1 to 2 months.

The size of cannabis seeds

This article has been conceived to answer all the key questions that we often get asked by clients and growers regarding the physical characteristics of our main product: premium-quality cannabis seeds.

Although it is true that ripe cannabis seeds tend to have a dark shell that can go from brown to black, with lines that look like tiger stripes, this cannot be regarded as a quality indicator by itself.

So in this case, an increase in size could be a direct indicator of this addition of calcium and magnesium, which is carried out in order to alleviate that macronutrient deficiency during growth. This has no impact on the plant’s potential for germination, growth, flowering, or yield, nor on the development of the organoleptic properties of the buds (aroma, flavour and effect).
