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.
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.
Some people believe you can see the gender of the strain based on the appearance of the seeds. Well, we can tell you that ain’t possible. Both female and male seeds look exactly the same.
Shape and size of a cannabis seed
Note: the moisture from your fingers can damage the seed. Please use linen gloves to prevent this.
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.
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.
It’s important to know what to expect and what to look out for before you buy cannabis seeds. In addition to important factors such as sufficient water, nutrients and light quality, a successful crop starts with high quality healthy cannabis seeds. But how do you determine whether a cannabis seed is healthy, viable and of high quality?
Cultivating marijuana plants from a seed rather than a clone can be quite exhausting since it requires a lot of care for the plants to germinate. There are some good practices that you should undertake before planting a seed to ensure maximum germination. First, you should start by soaking your seeds in container containing lukewarm water in a dark environment for 12-24 hours. Soaking the seeds accelerates germination by softening the outer shell. During planting, use seedling pallets soaked in water for 10 minutes. Place the seeds in a small hole ¼ in deep and then gently cover with dirt from the pallet.

Marijuana seedlings are very sensitive to light, and therefore you should ensure that you provide just the right amount of light. If grown outside, seedlings should be provided with direct sunlight. If inside, provide them with half a day of sunlight through a sunny window sill.
6) Leaves & Hardening Off
For young plants, it’s best to use bottled water as it has no chlorine added. If using tap water, let it sit for 24 hours before watering to dissipate any chlorine. Chlorine can also be eliminated by boiling for 20 minutes. Under normal conditions, after soaking your seedling pellet, it should contain all the moisture your plant needs before it comes above ground. As it grows, it will only need about a shot glass worth of water at most per week to keep the medium damp. Seedlings don’t drink a lot of water, which makes sense given their size. Your plant will do better in a growing medium which is damp. Overwatering is just as deadly as drying out.
When the plant has hardened off, roots will start emerging from the bottom of your seedling pellet and the plant is ready to be transplanted into a bigger pot. Be very careful not to damage the roots during this stage. Any stress will slow its growth.
Now bury it on top of the rooting pack so the base of its stalk is level with the top soil. Give it a proper watering to set the roots in the ground, then skip your next watering so the roots can take hold.
