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.
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.
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.
Source Your Seeds Well
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.
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.
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).”
Some smokers might be pleased to see some cannabis seeds in their bag, and might think themselves lucky. However, finding seeds in a bag is bad for various reasons. For one, this means the grower has messed up and allowed their female plants to be pollinated by an invading male. When flowers are pollinated, they stop producing THC-containing resin and divert their energy toward producing seeds. Secondly, the seeds will have added to the overall weight of the bag, which means less weed for your buck.
All types of cannabis, including white strains, are dioecious or unisexual plants, which means that they are capable of producing male and female flowers in various individuals. However, both types of flowers can be found in hermaphrodite plants. You can reduce the risk of males by choosing feminized seeds, and most white strains sold at weedseedexpress.com are feminized seeds.
White Widow is widely regarded as the queen of the ‘White’ family. She has often been used to form other ‘white strains’ or share genetic material with other ‘white’ varieties. Other denominators are that white strains are covered in trichomes, have a high THC level resulting in a powerful high. Popular white strains include Snow White, White Widow and Amnesia Haze x White Widow.
The white color in cannabis occurs in nature occasionally, as a consequence of a double recessive gene responsible for the absence of chlorophyll or because of a genetic mutation of the genes involved in pigmentation.
Do white cannabis seeds grow?
The short answer is ‘yes’. Most cannabis seeds are dark brown, but some are a silvery white and grow into beautiful plants with frosted white buds and even leaves that are laced with white.
Apart from the white weed seeds we want to go a little deeper into white weed species.
White weed is delicious, and often less intense than other varieties, so it is good for indoor or stealth grows. White strains are normally Indica-dominant and grow thick, bushy colas and have a rapid flowering phase. Even though most white strains are directly descended from White Widow, this isn’t always true – some white varieties are classed as White because of their high resin content.
Chlorophyll is the pigment responsible for giving color to plants. Its purpose, however, is more than aesthetic, as it is vital for the photosynthesis process. The chlorophyll of marijuana leaves is responsible for absorbing sunlight, triggering the chemical reaction that enables the plant to generate energy from carbon dioxide (CO₂) and the raw sap derived from water and mineral salts.
