Within min. Of coming in contact with water, the marijuana seed reacts. Inside the shell, a tiny embrio that has been in a state of suspended animation begins to produce a set of three chemicals that enduce growth: Auxin, Cytokinin, and Gibberellin. Auxin is found in the growing tips of both the roots, and the stem. It directs orderly new growth and develops the shape of the plant by inhibiting growth of the lower branches.
Cytokinins promote lateral growth and cell devision.
Gibberellin directs stem and leaf growth.
Together, these plant chemicals induce germination.
Whithin a short time- typically between one to five days, depending on the temperature and the seeds age, the root tip breaks through the surface of the hard seed shell. the root continues to grow and absorb water, but it still depends on the nutrients packed in the seed with the embrio.
Then from the other end of the soon-to-be stem, a pair of embryonic leaves (Cotyledons) emerge.
Sensing gravity, the plant orients itself so the roots point down and the leaves grow upward. Once the initial shoot emerges from the growing medium, plant growth follows the source of light the Cotyledons unfold, and spread out to face the light, sometimes with pieces of the cracked seed shell still attached to them.
The Cotyledons immediately start producing sugars using the process of photosynthesis.
Which requires light for the Cotyledons to absorb.




Hope that helps

Germination/Lift Off Germination complete, will place them in some of my trusty soil concoction (2 parts Canadian peat, 1 part cow manure, 1 tsp "Plant-Tone", Perlite & some Vermiculite) that worked out pretty well in my last grow. Will place the seedlings in a few small plastic cups & into my trusty closet under some indirect 45W fluorescent lights. More to come. Sic Semper Tyrannis :abduct: Rating: 5
