Silicon impacts on endogenous phytohormones are commonly analyzed in response to stress conditions. In rice plants exposed to heavy metals, Si reduced endogenous concentration of jamonic acid (JA) and salicylic acid (SA), while abscisic acid (ABA) first increased and then decreased after 14 days of treatment ( Kim et al., 2014): the ABA has an antagonist behavior with JA/SA biosynthesis. The effect of such phytohormonal changes on the expression of genes involved in heavy metal response still needs to be elucidated in Si-treated plants. Kim et al. (2011) also reported that Si reduced JA concentration in response to wounding, while Lee et al. (2010) reported an increase in gibberellins concentration in Si-treated plants exposed to salinity.

All of the supplements will feed into your plant and this silica source is as pure as they come. Whether you’re a new gardener or an expert, I would highly recommend this silica. How to Add Silica to Your Plants Today, we’re going to be looking at an organic source of silica for plants and the best sources. Although not a major plant nutrient, silica is still considered to be important in any grow room. One of the most abundant components in the earth’s crust, silicon is a major contributor to the plant kingdom. Yo dawg that is silica burning your skin. I do not want to overdo the silica. for that reason I do not apply more than one time a week. (note: my medium of choice is coco coir so keep that in mind if using different medium)Improved root system : Silica can help develop more robust root systems, increasing the surface area for nutrient absorption. It turns out silica can do a cannabis plant a world of good. Although they don’t need it, it can certainly increase their chances of survival, and potentially even the quality of their flowers. We recommend opting for supplements with a silicon dioxide concentration of at least 8%. Not only will this drive more silica into the cells of your cannabis plants, but it will saturate the soil and increase the availability of the chemical to your roots. Some products contain as little as 3% silicon dioxide, which might leave your plants hungry for more. How To Use Silica in Cannabis Growing You can apply silica to your plant either as a foliar spray or to the roots; but for maximum absorption, you should apply minerals with the aid of a foliar spray. Remember to dilute the silica and add the solution to the reservoir to avoid contamination with other elements.

Administer the silica as often as you do your other nutrient solutions—or less—as you don’t want to upset the balance. Better to underfeed than overfeed, as is the case with most nutrients. However, with silica this is even more the case. As a plant may grow well without it, underfeeding should not have any adverse effects. Using Silica With HydroponicsSilicon is needed as part of a balanced diet for every healthy individual. It plays a major contribution to bone and teeth development and as such should be included in our diet. The ligaments, joints, tendons, and tissues in the body require silica for strong and healthy development. The mineral also helps to balance the release of insulin by the pancreas. The skin, hair, and nails are not left out as they require essential minerals to be able to develop properly, and apart from calcium, silicon also helps out in that department. You also need to remain mindful of soil pH to get the most out of your silica products. As an alkaline substance, the chemical will increase the pH of your soil, so you’ll need to use a pH meter and pH down solution if things get out of hand. Wollastonite: A naturally occurring mineral, wollastonite offers a high source of soluble silicon while neutralizing soil acidity similar to lime. Similar to diatomaceous earth, research has proven wollastonite delivers levels of secondary nutrients such as calcium while suppressing plant stressors such as powdery mildew. However like we said earlier, silica isn't considered one of the primary nutrients which is why some growers can easily overlook it as part of their regiment. The Benefits of Silica It’s actually one of the most common minerals on Earth. Silica is the second most abundant nutrient found in the Earth’s crust. Thus it's highly concentrated in many soils, which in turn makes it a major part of plant tissues.

That being said, plants still need nutrients, and have to defend themselves from pests and disease. With the available evidence, it seems that both stopping and continuing to administer silica during the flowering stage are viable options. If you use silica, however, this chance decreases. The reason being that silica increases plant tissue. Seasonal adjustments : Adjust the application frequency during the dormant season, as the plant’s need for silica decreases. During this time, you can reduce applications to once every 1-2 months. Overapplication can lead to waste or unwanted buildup in the soil, so monitoring your plant's response and adjusting accordingly is key. Your soil is a living medium containing various microbes and bacteria. Some assist cannabis crops, but others cause problems, and silica might be the surprise cure. It helps protect against outside threats, increases productivity, and shields against toxins.

Conflict of Interest Statement

Mix about 4.4 ounces of powder for every 2.6 gallons of water, depending on the brand of potassium silicate you use. Liquid versions typically require 2–3ml.

CYA, In case this is not clear: The point in concentrated product is to use less not to supply more and overdo it. Keep in mind that silica is alkaline and could increase your substrate pH, so test before and after and adjust when necessary. Give silica to your plants as often as you would any other feed, or as stated on the product’s instructions. Using silica when growing cannabis hydroponicallyNo, you shouldn’t. All the advantages are made redundant by feeding your plants silica during flower. Although it makes the buds more resilient, it also diverts resources that could enhance the development of valuable terpenes and cannabinoids. Can you mix silica with other nutrients? But that’s not all. Add silica to poor-quality, low-nutrient soil, and you can increase the capacity of cannabis roots to extract every last molecule of goodness from it. Moreover, add it to healthy soil, and as your plants use up the stores of food in the soil, they’ll be able to extract more as the levels deplete. Protection against toxic metals
