Why Plants LOVE Silicon

Ever heard of liquid silicon? Plants will survive without it, but they’ll be much hardier with it! We're talking about liquid silicon!

 

When absorbed by plants, it:

 

• Strengthens roots, stems, leaves & branches

• Improves disease & pest resistance

• Builds heat, cold, humidity & wind tolerance

• Prevents nutrient deficiencies

• Enhances growth

 

Use it, and you'll get bigger, stronger crops that grow and yield better. Here’s the science behind silicon.

What's Silicon?

 

 

It’s a natural element that helps create everything in the universe.

 

You can find it as sand (silicate dioxide).

 

It’s also in sheet silicates, which form over 90% of the earth’s crust! Sheet silicates are made of silicon, oxygen, metals & minerals.

 

Silicon is extracted from sheet silicates as a monosilic acid, which makes it available to plants.

 

How it Works

 

 

Silicon mostly strengthens the physical structure of your plants.

 

It thickens cell walls and the bonds between cells.

 

When plants take in silicon, they’ve got about 24 hours to decide where to put it (between or in cell walls). Silicon deposits then set in place - like cement! As a result, cells become thicker and stronger.

 

All areas of your plant are affected – roots, stems, branches, leaves.

 

Increases Disease & Pest Resistance

 

 

Silicon bolsters cell walls and the bonds between them. This makes it tougher for pests and diseases to get a foothold & spread.

 

On top of this, plants are able to create a thick outer coating that bugs won’t break through (even aphids & spider mites). Diseases won’t fare much better - that includes powdery mildew, Pythium (root rot) & botrytis (bud rot).

 

Best of all, plants are pretty clever when it comes to silicon. They can direct freshly absorbed supplies to stressed or vulnerable areas when under attack! That's an intelligent natural defense system for you! It's one of the reasons why you need to dose often.

 

Prevents Wind Damage

 

 

Over time, stems strengthen to the point bulky plants can stay upright through challenging conditions. That’s without support devices like yo-yo’snetting (still use them).

 

With a structure like that, rushes of air are less of a risk. Plants are way less likely to snap or topple over when hit by gushes of air. Instead, they’ll bend and flex with the movement of air.

 

Supports a Bigger Yield

 

 

In flowering, plants can support heavier fruits and flowers, encouraging plants to yield more.

 

Enhances Growth & Development

 

 

Silicon helps build a bigger, stronger Phloem and Xylem in the stem structure. This means plants can translocate more nutrients and water, at a quicker pace.

 

This, in turn, means plants absorb more elements that are tough to uptake (e.g. calcium). As a result, plants grow bigger and faster.

 

Boosts Heat, Humidity & Stress Resistance

 

 

Since plants are working more efficiently, they can function better under heat, humidity & other extremes (like lack of water!).

 

For example, at temperatures over 30oC, plants stop turning food into energy. They just don’t have the water they need for it - too much is lost through transpiration (sweating).

 

With silicon strengthening cell walls, water can be moved at higher temperatures and the rate of transpiration drops. This means plants can continue turning food into energy.

 

Strengthens Cuttings & Seedlings

 

 

Toughen cuttings and seedlings from day 1 by applying silicon as a foliar spray. Doing this lays the foundations for future growth!

 

Increases Photosynthesis

 

 

All of those rich, green, wide spanning leaves that silicon helps plants produce are exposed to sunlight, CO2 and water. That means plants can photosynthesise more. That’s where plants use CO2, H2O and sunlight to make sugars.

 

Prevents Nutrient Deficiencies & Toxicity

 

 

Silicon encourages plants to absorb more:

 

• zinc (for growth & photosynthesis)

• calcium (for growth, enzyme activity metabolism & uptake)

• nitrogen in soil (for veg growth & most plant functions)

 

It also balances the uptake of phosphorus, to prevent toxicity.

 

Because plants absorb more zinc, calcium and nitrogen, they absorb less of the nutrients they don’t need much of - like aluminium, manganese & iron. This stops unhealthy & excessive nutrient consumption.

 

How to Add Silicon

 

 

In soil, hydro & coco, you can boost silicon levels with SHOGUN Silicon.

 

It provides a soluble form of silicon (potassium silicate), which is readily available to plants. As a bonus, it’s a good source of potassium, which we all know is vital in flowering.

 

Bottled base nutrients do not contain silicon because it needs a high pH to stay soluble.

 

So, to include it in your base feed:

 

• Add your silicon to water

• Mix through and reduce your pH to just below 7

• Add your base nutrients

 

Remember, plants only have 24 hours after absorption to deposit silicon. This means, a little and often dosing strategy is best.

 

To really see the benefits of silicon, you need to apply on a regular basis, throughout your grow.  We recommend applying it as a root feed, with an occasional foliar spray when needed.

 

Propagation:

 

Propagating plants are still very delicate. Apply silicon as a foliar spray

 

In Soil:

 

Soil already contains some silicon – about half the amount plants can use.

 

To get the best out of plants, add some more as a foliar spray.

 

In Hydro & Coco:

 

Unless you add it yourself, plants won’t get any silicon. You can add it as a root feed or foliar spray.

    Fantastic info thanks. I have had a few problems in my hydro set up. Things were fine in veg a little thin the branches tho. Then on flower things just went south. My fruits dragged the branches down drastically. So if I was to add silicon your saying this wouldn't happen maybe as much? The fruits weren't even that big but still the branches really dropped resulting in me having to tie them up. Thanks for your info hope silicon helps in my next lot.

      Hi Billy, the SHOGUN Silicon will certainly help with this. When using silicon, it is important to add it to your water and adjust the pH to below 7 before adding any other nutrients and boosters to avoid precipitation in the solution. It is also a good idea to use some form of plant support like yo yos or crop support netting if you are growing heavily fruiting plants.

      Hope this helps.

      Hi there,

      SHOGUN Silicon strengthens a plant's defence system, making it more resilient to attacks from bugs. Using the product will significantly reduce the chances of thrips showing up, but you'll also want to have a general pest control spray to hand so that you're ready for any sudden outbreaks - we highly recommend Protector. If the dreaded insects do manage to launch an invasion you can order thrip predators through us, which promise to effectively treat the problem. Nematodes are great for destroying the eggs and larvae of thrips, just not the winged bugs that actually produce them.

      Hope that helps!

    Hi there GroWell,

    Silly question: you mention silicon is only to be used as a foliar feed with soil - why can it not be used during watering of the soil?

    Cheers

      Hi Nick,

      A certain amount of silicon is normally available in soil already, so we tend to recommend foliar spray application rather than root drench. However, silicon can be used during watering of the soil if required - we've amended the article to more clearly reflect this point.

      Thanks for your question!

    Hi there,

    I can't find the correct dosage of silicon to use for a foliar feed - is it 1ml per litre, as per the amount for soil?

    Cheers,

    Nick

      Hi Nick,

      The 1ml per litre dosage recommendation is for root feeds and foliar feeds. You could even go as high as 2ml per litre for spraying on leaves, stems, etc.

      After dilution the solution will be very basic and the pH may climb above 9 with the higher dilution, so you will need to adjust this back down to between 5-7 before application takes place. Make sure you do this a few minutes prior to turning off your HID lights to avoid any radiant heat evaporating the solution on the leaves - otherwise this can cause damage to the tissue.

      Thanks for getting in touch!

      Hi there,

      We would only recommend using SHOGUN Silicon with BioBizz products if it is applied as a foliar feed... but you will still see a positive change in your plants! You can actually apply SHOGUN Silicon as a root feed but a certain amount of silicon is already available in soil so foliar feeding works better, providing a tremendously beneficial top up.
