Jiffy Peat Pellets. Our customers prefer Jiffy Pellets for seed starting. The outer net of the pellets is decomposable, which means it will degrade under compost conditions (speed and degree will vary with conditions), while retaining its strength through the critical seeding and transplanting stages.ur customers prefer Jiffy Pellets for seed starting.

Heterochromia means different (hetero-) colors (-chromia).. Usually the term is used to describe the condition where a person has different colored eyes â one blue eye and one green eye, for example. Other terms to describe different colored eyes are heterochromia iridis and heterochromia iridum. Iridis and iridum refer to the iris of the eye. The iris is the thin, circular structure that surrounds the pupil and contains the pigment melanin, which gives our eyes their distinctive color.
Melanin. At the most basic level, the answer to what causes eye color is the pigment melanin. Because melanin isn't fully present at birth, many babies have blue eyes at birth that will later change to brown or green. Melanin can deposit in either the front or back layer of the iris.ris color can vary widely. Eye color in humans varies from very light to very dark. Eye color should more accurately be called iris color, since the iris, the central part of the eye, contains the different colors.
