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.
Quality seeds are the key to healthy plants and good harvests. While proper feeding/watering and good light quality obviously also affect the health and yield potential of your plants, starting a grow with top-shelf genetics is equally, if not more important. But how exactly do you tell quality cannabis seeds apart from the rest? In this article, we’ll show you exactly how to spot top-quality cannabis seeds, avoid duds, and start your grow off right.
Growing Seeds From A Bag (Bagseed)
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.
Are your seeds light or dark in colour? Are they tough or do they turn to dust when you press them between your fingers? These are just some of the ways to tell if a seed is healthy and worth growing. Keep reading to learn more.
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.
Autoflowers can be started in early spring and will flower during the longest days of summer, taking advantage of high quality light to get bigger yields. Or, if you get a late start in the growing season, you can start autoflowers in May or June and harvest in the fall.
To create a dark, protected space, take another plate and flip it over to cover the seeds, like a dome.
Tips for growing autoflower marijuana seeds
If growing outside, some growers prefer to germinate seeds inside because they are delicate in the beginning stages of growth. Indoors, you can give weed seedlings supplemental light to help them along, and then transplant them outside when big enough.
If you don’t like the flavor, effects, or even the look of the bud, then it’s probably not worth growing.
Autoflowers don’t need lots of nutrients because they’re small and don’t spend much time in the vegetative cycle. They won’t need as much veg nutrients—such as nitrogen—but will need more bloom nutrients.
However, a greenish colour is a clear sign of immaturity, which means that the seed hasn't developed fully or it hasn't received all the necessary resources to reach full maturity. In this particular case, if you purchase seeds with this colour you need to contact your supplier immediately and try to have them replaced.
If, on the contrary, the seeds seem too big, this may be caused by a lack of macronutrients during the plant's growth cycle. As any grower with certain experience will know, calcium deficiencies are corrected by adding calcium and magnesium, a combination that helps reestablish the perfect nutritional balance of plants.
Some customers, for instance, contact us to tell us that they have bought Critical + seeds and they believe they look too small. But this is a normal feature of this strain: we've seen millions of Critical + seeds and we can confirm that they are naturally smaller than others. It is therefore incorrect to think that this is a sign of poor quality.
So we can openly say that this difference is simply visual. If we take the example of a Moby Dick seed, its dimensions will most likely be bigger than those of Critical +, although you can also find slight variations between seeds from the same strain. Don't forget that, as with all living beings, cannabis seeds are also biologically different amongst themselves.
Critical + is a clear example that colour, contrary to what many growers believe, is not necessarily a quality indicator: these undeniably high-quality seeds exhibit a very light grey, almost whitish grey, to a medium grey colour.
This could be compared to a newborn whose physical appearance quickly evolves during their first few days of life in order to adapt to the completely new outside environment.
In some cases their shape is more linear; whereas in others one of the extremities can be rounded whilst the other is more pointy. But this is no reason for concern: as with size, these slight differences in the outline of the seeds are purely visual and have nothing to do with quality.
