Coco coir substrates are a popular choice for cannabis cultivation. Coco coir is a sustainable and renewable resource and can be easily composted after use. It can be purchased loose or compressed (for growing in containers) or in compressed grow cubes (as an alternative to rockwool blocks). Coco coir can be used once and discarded or used as a top …
FOR CANNABIS CULTIVATORS Cannabis cultivation requires careful planning and strict protocols to avoid crop failure from microbial contamination. Integrated pest management is a concept that includes cultural, mechanical, biological and chemical control methods. These methods are intended to be incorporated at a preventative level to counteract the risk of exposure to pests and diseases and subsequent economic losses. Chemical control …
Pest management in Cannabis cultivation is crucial to optimizing yield and quality. The selection of the right pesticide and dose for the target pest are important decisions made by growers. Making the right decisions in how the pesticide is applied is equally important in optimizing pest control. The following paper outlines important considerations for optimizing pesticide applications in Cannabis. These …
NUTRIENT RUNOFF & EC MONITORING The electrical conductivity (EC) of soil is an indicator of soluble salts that may be present in the root zone. Soil salinity is an important factor of soil health. Excess salinity can affect crop yields, nutrient availability and soil fertility. Although EC does not provide a concentration of specific elements, it has been correlated to …
Plants take in essential nutrients for growth and development through root systems anchored in soil or other growing substrates. The interactions between plant roots and the growth media determine whether plants receive sufficient nutrients. The plant nutritional status is dependent on three key components of plant and substrate interactions: 1. Soil environment 2. Plant nutrient 3. Plant physiology In this …
Successful seed germination requires optimal conditions including moisture, warmth and suitable grow media. Light is not necessary until the first leaves, or cotyledons, have emerged from the seed shell. Once seeds germinate, it is important to maintain substrate and environmental conditions for optimal seedling development. Seeds can be started in a variety of growing mediums, including rock wool, peat moss …
RHIZOSPHERE PH ANDNUTRIENT AVAILABILITY UNDERSTANDING RHIZOSPHERE pH The rhizosphere is the area of soil directly surrounding the plant’s roots. Root secretions and microorganisms affect the soil chemistry and biology of this area. Compounds found in root exudates consist of water, amino acids, organic acids, carbohydrates, proteins and vitamins. Many of these compounds serve as food sources for microorganisms in the …
MANAGING CANNABIS FUNGAL DISEASES Cannabis plants can be susceptible to a wide range of diseases, including those caused by viruses, bacteria and fungal pathogens. While viral and bacterial diseases are not as prevalent in cannabis as they may be in other crops, fungal diseases present often and with a vengeance. Root and stem rot, bud rot and powdery mildew are …
WATER QUALITY ASSESSMENT Water from different sources has broad variability. An irrigation water analysis can determine what components, if any, exist that may present a clogging risk. The presence of suspended solids, high pH, organic matter and hardness drastically increases the chance of irrigation system complications. Poor water quality will also affect nutrient performance and availability to plants. There are …
ARE THEY WORTH IT? Essential plant nutrients are classified as such if they are required for the function of plant metabolism. To date, there are 17 known essential plant nutrients, but there are also some elements that are considered to be beneficial to plant health and growth. This means that the plant’s metabolism will function without them, but there are …
Plants require light, water, carbon dioxide, and minerals to grow. Plants are unique in that they are sessile and must receive elemental nutrients through roots in a growing medium. There are 14 elements that are essential for growth and development that plants receive through roots. Each nutrient plays a different role in the plant from structural components to regulation of …
