Similar to most plants that can be consumed, the cultivation of cannabis starts with a seed. Also known as marijuana, cannabis comes in the form of a seed and can be purchased online from an array of vendors all over the globe. Some businesses only sell the most popular types of cannabis seeds while others sell more breeds and crossbreeds than most individuals can name. Despite which types of seeds are purchased, the nurturing process is relatively the same. Every plant requires proper soil, specific levels of warmth, adequate lighting and the right amount of water for optimal growth.

Understanding Cannabis

Cannabis, a member of the Cannabaceae family, can be categorized as a dioecious plant. Essentially, this means that the plant can be either male or female. Despite being able to survive as either sex, only the female plants can actually be consumed and have the proper effects. Scientists believe this is due to the fact that the female plant is trying to protect itself from harm. As an annual plant, cannabis lives a normal life span from approximately April until September. There are four species within the genus family, which are sativa, indica, afphanica and ruderalis. Of these four, the two types that can reach outstanding heights are sativa and indica. Truly impressive stalks can grow over twelve feet and produce females that may feature up to 29 percent THC, or tetrahydrocannabinol.

Buying Seeds Globally

As laws are changing, more and more individuals are testing their green thumbs with the plant cannabis. Websites like Marijuanaseeds.co.uk, founded in the United Kingdom, rely on their bountiful list of products and sell more types than most individuals would care to grow. Amsterdam Marijuana Seeds, on the other hand, are becoming quite popular for those wishing to grow cannabis year round. This particular site only sells the most popular brands, such as Big Bud, Northern Lights or White Widow.

Cultivating Cannabis Requirements

For those deciding to grow cannabis, many of the methods from typical plant growth can be applied. The specifics change with each plant, but this general guide should keep the leaves from wilting. The reason to know the exact methods is much like a farmer understanding his crop. Under the wrong conditions, the plant will be less healthy, which means that the consumption process will not feature the expected nutrients. Cannabis seeds require light, soil, warmth and water.

1. Light

Growing indoors is known as artificial lighting while growing outdoors is known as natural lighting. Artificial lighting needs to mock natural setting so a rotation of light to dark is recommended for ideal growth. When using artificial lights, it's best to light the plant for 16 to 20 hours per day and leave the plant in darkness for 4 to 8 hours per day. Plants can handle 24 hours of light but the dark period reduces the risk of decreased photosynthetic response or having issues with overall vascular development. For those having trouble reaching the flowering stage, researchers have found that rotating the plant to 12 hours of light and 12 hours of dark may trigger this effect. The prolonged darkness causes the calyx development to initiate, but the darkness range truly depends on the type of plant.

2. Soil

Except for hydroponics, soil is generally required for any seed to grow. Despite the brand, each type of soil must include the nutritional elements nitrogen, phosphorus and potassium. These four elements are usually added through fertilization. Commercial fertilizers, even those labeled as organic, often have the means to cause a rise in pH levels within of the soil. This rise can harm the plant as it makes the soil more acidic. Generally, most types of soil aren't harmful, but when growing a plant for consumption, it's always wise to take caution.

3. Warmth

When growing the cannabis seed, the ideal temperature is between 75 and 85 degrees. Plants in ranges below 75 or above 85 tend to slow down in terms of growth expectations. Not only is the height or flowerization of the plant in harm's way, the plant may also lack THC potency, which is what gives cannabis its medical status for pain relief. Despite growing a prize-winning plant of a dozen feet or more, if the plant only features a one-percent potency, it's essentially a failure. In most cases, necessary warmth comes from natural elements and proper lighting.

4. Water

Temperature and light highly affect the amount of water necessary for a healthy cannabis plant. The size and age also factor into the plant's complete ability to handle water. Plants with weak or wilting leaves may be suffering from a lack of water. Over watering, on the other hand, can actually kill a plant and is more difficult to recognize. Generally, try and keep a strict schedule for the overall health of the plant.
