silica spray

Monosilicic acid (MSA) is the only form of silicon that is readily available for plant uptake, whether through roots or as a foliar spray. Some silica compounds, like potassium silicate though, may not be readily absorbed through leaves. Some may oversimplify the process or make misleading claims about silica absorption, makes it challenging for growers to choose effective products. Cannabis is a dicot plant. While monocots like rice and grasses are known for significant silicon accumulation 10-20%, many dicots, especially those in agricultural settings, can utilize only 0.5% in its leaf. Doesn't mean it's not useful, it's super useful especially when under wayer stress, but grosssssly over marketed, handful of diatomaceous earth in your soil will do you good entire grow. Silica is immobile within the plant so I would not advise foliar applications of anything that is immobile as it will stay locked into the leaf it absorbs. Anything else is a sales pitch. Probablly won't hurt, I'd just stick to letting the plant uptake through its roots and let it decide for itself how much silica it needs.

Years ago it was mentioned on label, that it can be used as foliage spray too. Buddha’s Tree Solar Green Power Chatgpt says its still on, haven't used it for at least 4 years. Liked the product.
