At farmers Lab seeds we hand examine every seed we sell under magnification as well as perform dissections and tests on random seeds.
Why do we do this and what does it matter to you?
Marijuana seeds have 3 main structures that need to be intact in order to germinate and can be subject to damage.
- the seed covering (seed coat or testa);
- the embryonic axis and
- the supporting tissues also known as the endosperm
First, we conduct a Physical examination on every seed we sell.
The characteristics of a healthy seed is glossy and gray with sometimes green or brown shades. It will have a good weight from a healthy embryo and a fleshed out appearance with a distinct surface pattern.
Conversely an unhealthy or old seed can be crinkled or cracked.
An immature seed on the other hand is lighter, more green and spongier than a seed that is mature.
Second, we conduct randomized flotation and dissection exam from every batch of seeds we acquire.
First we drop random seeds in petri dish of water to see if they sink or float. A dry or an immature seed will float whereas a healthy mature seed will sink.
Next we slice open and examine random seeds from every batch. Seeds that are black inside are becoming ready for fertilization and have low probability of germination. Seeds that have a musky, oily smell are typically old and on the verge of going bad.
Finally, we germinate random selection of seeds of every variety to insure 100% germination.
After this process if the seeds are found satisfactory they are ready to be blister packed and sold.
