GG Mono includes a wetting agent for superior foliar performance. This means that (like anything that bubbles) it does generate some foam when mixed in R.O or soft water, especially if strong air pumps are in use. The easiest way to avoid this is to simply add GG after CalMag so that you’re effectively adding it to hard water.

No need. In fact, adding it last is preferable as it will reduce any foaming in soft / R.O water. The whole “add Silicon first” reflex is due to other Silicon products being based on highly reactive, unstabilized Potassium Silicate which has a very high pH. Because of this it was necessary to add older products to water first, stabilize pH and then proceed to add other nutrients etc. As GG Mono is NOT based on potassium silicate, and is stabilized in the bottle, it is not subject to side reactions and does not cause pH swings – or dropout.

Not even too strong for seedlings – for a couple of reasons: First: monosilicic acid isn’t harmful to plants in the concentrations we recommend: any MSA not used turns into harmless trace silicates and the stabilization biodegrades rapidly after use. 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 – simply use less GG Mono!

Some first Generation 1% strength Mono products claim to be optimized at max concentration: they aren’t: all water based formulations are limited by chemistry to around 4% concentration. 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 a 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!

Also, as Silicon isn’t mobile once laid down in plants as Silica, around a week after you stop using GG Mono there’s nothing active left in your plants or system (except the MSA that’s naturally in there from tap water etc).

GG mono is completely stable until mixed with water. It does not decompose or lose effectiveness over time, however, we recommend storing GG in a cool place and using it within one year of purchase to ensure your GG mono remains in good condition. Please note however that as any water / humidity ingress will damage the water activated product, we recommend using it within 6 months of opening especially in humid conditions.

Via solution (applied to roots): our biodegradable stabilization progressively releases monosilicic acid over a period of about 7 days after first mixing with water. For this reason, there is no benefit to be obtained by using it or adding to your reservoir / tank more than once per week unless you’re running a recirculating system with Si hungry plants – if you have measured the system Si levels to be exhausted by all means re-apply.

Daily application of solution, for example if you’re running a dripper system, is absolutely fine – beneficial even. In hand watering situations it’s up to you. You can apply once a week or every time you water. More does more, but one application per week will still deliver tangible benefits.

Via Foliar spray (applied to leaves and not roots): If you need to (pest infestation or serious mildew pressure for example), on woody stemmed plants it’s normally safe to apply twice weekly for a period of a few weeks if fast growth is occurring and new leaves are forming. However, do not drench plants, and make sure you’re not allowing significant amounts of foliar solution to drip / run into the substrate as it’s a much higher concentration than the safe rate for roots.

Not recommended…That’s not to say if you make a mistake you’ll automatically damage your plants – we do build in a safety margin with our dosages – but there’s little advantage to be gained from exceeding our recommendations, and you risk overloading your plants. As with any garden product, significant excess dosage risks causing issues: in excess Silicon blocks access to calcium and your plants will wilt and potentially suffer permanent damage.

If you have over-applied GG mono, the best thing to do is flush your substrate through with as much water as is realistic – ideally a few times the container volume. In open soil water thoroughly. If everything is ok after a day or two, it’ll be fine (and it generally is).

If you can, do both. Foliar application biases silicon uptake 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.

Yes, GG mono really is completely pH neutral. The reason Silicon supplements are associated with aggressively high pH is because most of them are based on potassium silicate. GG uses totally different chemistry to other products and so doesn’t have these drawbacks. Add it after nutrients and final adjustment, or before – whatever suits you. NB: if you add GG to R.O water with nothing else you’ll get unreliable pH readings – add it after any soluble nutrients and you’ll see it has no effect on solution pH.

Yes! Their biodegradable stabilization progressively releases monosilicic acid over a period of 7 days after first mixing with water. This means the product is stable in an AutoPot Reservoir for up to 7 days!
