No problem! We say do both because foliar biases silicon slightly towards leaves, and when applied via irrigation there is a slight bias towards the internals of the plant. So ideally do both. BUT: One of the unique attributes of mono is the ability to provide plant-wide benefits via foliar application alone. Other forms of silicon only provide system wide protection and faster growth via irrigation. Why? Again, because they have to be turned into mono first before they work….not so with mono. So if you can only irrigate, or only spray: no problem! You’ll still get plant-wide benefits and protection with Grow-Genius.
No. It is completely neutral. Add it before or after nutrients and final adjustment. Whatever suits you.
In short: a variety of structural and metabolic ways. This ranges from improved uptake of water, to better protection of the plant’s epidermis from heat and wind thanks to thicker and more plentiful trichomes (hairlike structures on stems and leaves).
Unlike mystery “stress reducing” products based on PGRs, silicon is a fundamental plant nutrient that has been thoroughly studied and evaluated by independent scientists and researchers. This doesn’t mean we have all the answers to all the details of each mechanism yet: but the results are not debatable. We encourage you to read through some of the hundreds of studies into various aspects of silicon performance in different crops: many are easily accessible online such as this fascinating look at water management from the US National Center for Biotechnology Information: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5844968
No. GG mono is completely stable until mixed with water. It does not decompose or loose effectiveness over time, however, we would recommend using it within three years of purchase to ensure the bottle remains in good condition as any water ingress will damage the product.
No. For a couple of reasons: First: monosilicic acid isn’t harmful to plants in excess: it’s just wasted if you use too much. We recommend the dose we do because it’s optimal for silicon loving plants when applied weekly (most competing brands require more frequent application).
And second: if you know your plants need less (if for example, the species is a ‘silicon rejector’) – you simply use less GG Mono!
Some first Gen 1% strength Mono products claim to be optimised: they aren’t: all Gen 1 water based formulations are limited by chemistry to 4.2% concentration max. Now, that doesn’t mean they aren’t effective: they are: even at 1% strength – but it’s not a reason to pay the same for 1% as you could for 40% strength product! So in short: there’s no risk to 40% mono: and if you want it weaker: use less, and save even more money!
