Extracts from the yucca plant commonly contain micronutrients like iron, zinc, manganese, and copper. Therm X-70 is considered a natural wetting agent and contains saponin derived from the yucca plant. This active ingredient serves in plant defensive mechanisms against microorganisms and various insects that affect cannabis plants. Part of why saponins make great wetting agents is because they produce a foam when dissolved in water. Water and fertilizer uptake increases when saponin reduces surface tension.

Saponin is a natural plant extract found in hundreds of different plants that contains antimicrobial properties, helps spread sprays across the plant’s surface, and works well to increase water and fertilizer uptake (4). Natural wetting agent containing saponin by American Extracts.

You will typically find harpin proteins in powder form in products such as Axiom. They are relatively new to agriculture, as harpin protein products were first registered in the United States in the year 2000 and have only been gaining in popularity among growers since.

Harpin proteins are considered safe and are non-toxic to humans as well as the environment. Commercial production of Harpin αβ comes from genetically modified E. Harpin αβ is a protein molecule that consists of fragments from other harpin proteins. There are Harpin proteins and Harpin αβ proteins available for purchase at many hydroponic grow stores and they are similar. Increasing a plant’s SAR is ideal because unlike pesticides it does not allow pests to develop a resistance to the substance (2). Unlike most pesticides, harpin proteins will not interact with fungal spores and bacteria directly, instead it increases a plant’s Systemic Acquired Resistance (SAR). This defensive response can make a plant more resistant to several different fungal and bacterial diseases. Harpin proteins act by initiating a defense response in plants when applied. Harpin proteins product from Rx Green Technologies known as Axiom. Implementing a sound foliar feed schedule is easy, applications are usually repeated at 14-day intervals or as otherwise stated on the product label. Some of the most common products used for foliar feeds include: Heavy 16 Foliar, BioAg Ful-Power, Regalia, Photosynthesis Plus, Superzyme Biological Growth Factor, ThermX-70, and General Hydroponics Armor Si. Foliar feed solutions should have their pH adjusted according to the label, but when in doubt it is safe to use the same pH level that is used for nutrient soil applications. Common Foliar FeedsĬertain nutrients for plants can effectively be applied as a foliar feed at certain stages of growth. Leaf damage and stress can occur and in extreme cases it can kill the plant if done incorrectly. It is possible to damage plants if concentrations of nutrients in foliar applications are too high. Leaves have a waxy cuticle that restricts water entry and causes water to bead up on the plant, preventing nutrients from being absorbed by the plant which is why it is also recommended to use a wetting agent (surfactant) to increase the coverage of the spray on the leaves. Even though the major pathway for nutrient uptake for cannabis plants is through the roots, it is still possible to provide plants with nutrients through its leaves. Why Foliar Feed?įoliar feeds will not replace a good soil or nutrient regimen, but can provide necessary nutrients for less stressful transitions, to improve Systemic Acquired Resistance (SAR), and provide nutrients for optimal growth. The goal is to provide plants with the necessary nutrients at an accelerated rate than uptake through the roots which is great for correcting nutrient deficiencies and other grower mistakes related to the plant in the garden. These sorts of sprays can be applied to clones, vegetative plants, and plants in early flower stages of growth. A spray with a smaller droplet size preferred for foliar feeds to increase its effectiveness. Foliar fertilizers are diluted fertilizer solutions, proprietary blends of nutrients, microbes or bio-stimulants that are meant to be applied directly to plant leaves.
