After the first pair of embryonic leaves receives light, the plant will begin to produce another small set of new leaves. These leaves are different from the first two and may have some more noticeable marijuana characteristics, such as the threerounded, finger-shaped points. As the seedling grows, more of these leaves are formed and bush upward along with the stem. Some stems are very weak at this sub-stage and need the support of a small, thin wooden stake tied to the seedling with some fine thread. The seedling sub-stage can last between one and three weeks. At the end of the seedling sub-stage, your plant will have between four and eight new leaves while some of the original bottom leaves and cotyledons may have dropped off.

This is a seedling that is approaching vegetative growth. It is around this time that growers may move these plants to the main grow room.

This is a cutting, or clone, that is being prepared for propagation. You can tell the difference because the cutting looks more like a branch than grown from seed.

This is a mother plant that is kept as a clone donor. You can identify mothers by their many branches, created by the grower to provide lots of areas to cut from.

Here we have a range of plants in vegetative growth in the grow room. Notice the healthy upward pointing leaves.

This is a good example of how a high trichome count can undermine the principle that a high calyx to leaf ratio is a desirable trait in marijuana plants. Here the trichomes almost seem to be covering the plant in a balm.
