Superthrive Dyna-Gro PROTEKT - Silicon Plant Supplement

$26.50 NZD

*Dyna-Gro is in the process of changing to new branding under the Superthrive brand name. There is no change to the product inside, just the label only on the outside*

*One free 3ml pipette included in every Dyna-Gro order*


Why choose Pro-Tekt?

It's in the name! Dyna-Gro Pro-Tekt does just that. Protects. Think of it like your plant's body guard. Tough. Strong. Ready to fight. The power of silicon is no secret to agricultural scientists. It's just taken us house-plant hobbyists a while to catch on to this clever secret-agent to protect our indoor plants. 

We simply shouldn't have to live with a constant fear of pests and diseases. Creepy crawlies and mysterious ailments. Then before you know it, your entire jungle's infested. Silica is the second most abundant mineral that makes up the Earth's crust. It makes up more than 95% of all known rocks. But indoors? Our plants rely on us to boost the silicon their soil is missing, so they can protect themselves the way nature intended

PLEASE NOTE This is for the taller, round bottle in the first photo, not the shorter, square bottle. I supply a free pipette with every Dyna-Gro order to make measurement easy.

What does Pro-Tekt do?

 Source of silicon and potassium for faster, stronger growth, and supporting your plant's natural defences against insects, fungal infections and disease.

Whether one plant or your whole gang are prone to pests or constant problems, Pro-Tekt helps them fight back. If the worse happens and you lose a plant, use Pro-Tekt to help prevent the rest becoming the next victims.

Frequent and often
is the best defence. Don't leave it too late. It's better to feed weekly, but if you're already dealing with bugs or disease, you can foliar spray for the fastest protection (see directions for use below). 

SUPPORTS: Thanks to stronger, broader stems, Pro-Tekt also helps nutrients and water travel more easily and efficiently to where they're needed. Even stubborn ones like calcium. Stronger stems support bigger, heavier leaves, flowers, veges and fruit too. 

RESISTS: A bonus side-effect is plants handle neglect and stress better too! Good news for busy plant parents and forgetful waterers, as well as the over-carers. Silicon helps plants be more resistant to drying out, able to cope better with inconsistent watering, and better able to handle both heat, cold and drafts (ideal for the NZ climate). 

The Secret of Silicon is worth a read to learn more.

Directions for use

Dilution rates vary. 
For adding to every water (recommended), 1ml to 1.5 litres is the maintenance levelSilicon is a very safe supplement so you can adjust dose to match your plant's needs. Check the Pro-TeKt directions for use before use. 


Pro-Tekt keeps silicon in an easily-absorbed liquid form using a high pH concentrate base. Most plant foods are low pH. Make sure you mix Pro-Tekt with water to dilute it first BEFORE adding other foods or tonics
Otherwise Pro-Tekt will turn into a lump of silicon gel! I mix Pro-Tekt with about 3/4 of the water I'm going to use, give it a stir, add my fertiliser, then add the last 1/4 of water and feed.

Dyna-Gro ProTeKt Reviews 

"I added this to my nutrient line up over a year ago and could not be happier. The plants are sturdier and more resistant to heat and pests." @doug_us

"This is one of the best additives for your plants. Silica makes your plants strong and resistant to everything." @smitty

"Used in conjunction with neem oil to kill the plethora of fungus gnats everywhere in my house. Have used 2 times and not only is the infestation 99.9% gone, my plants look very healthy and shiny now. This stuff is amazing!" @cua_usa 

"Great product!!! Use with neem oil to make a fantastic insecticide spray." @nathanaiel

"Tons of uses and no side effects, I recommend this highly for anyone serious about horticulture." @j_ayres

"Came upon this product at a greenhouse/grower I know and gave it a try. Fantastic product and very easy to use. I have over 70 plants in my house including orchids and I use nothing else but Pro-tekt and Dyna-Gro." @b.hamilton

"So many benefits from using silica. Makes plants strong and toughens plants leaves in a sense for a form of pest management. All dyna grow products are quality in my opinion." @christopher_s

"This helped my plants grow thicker and look healthier. A little goes a long way too." @JJ_voice

"Helps to strengthen root system and make the plant more resilient to changes in temperature and to disease. Highly recommended to all growers!"

"...It has indeed improved their resistance to drought. I used to water them every 2-3 days in the summer, but now I can go as long as 5-6 days or even longer between waterings in the warm season and they still don't wilt. My plants are extremely healthy and strong now. I used to baby them and tried to touch them as little as possible.

Now I can handle them, rough them up, brush by them when I'm walking and it doesn't bother them one bit. Even when the wind blows them over I pick them right back up and there are rarely broken stems or damaged leaves. Amazing! I use Pro Tekt on a wide variety of plants - from tropicals such as peace lilies to epiphytes such as bromeliads and orchids to succulents such as cactus and Euphorbia."

I love this web store

I really love the products this website sells, especially the Dyna-Gro series. I've been using them for a while, and they are truly effective. Whenever I need something, I always come here first. Also, I recently came across Anna's article in a magazine (New Zealand Gardener), and it provided us with valuable advice and shared experiences. Thank you, Anna. This website not only offers great products but also valuable knowledge and information for users. I'm very satisfied and grateful. Keep up the good work, and I look forward to more exciting content and products!

Love it

My Thai constellation is loving it. No more Browning leaves 🥰


I use this in conjunction with foliage pro and that provides all the nutrients my potted aroids need. The seller is personable, ships fast, and communicates well. Lovely buying from you thanks

Dyna-Gro ProTeKt - Silicon Plant Supplement

Good alone or because I'm also using GT foliage focus?

I bought the Dyna-Gro ProTeKt silicon supplement at the same time as GT foliage focus and am going to give the same review for both as I don't know if its one or the other or because I am using them together.
With respect to the GT product I water weekly and that means weakly really rather then weekly - we are heading towards Winter my plants do not need weekly watering but they do need the GT weakly. I have also been giving them the silicon supplement at the same time so it is hard to tease out what of either or is it both that my plants are enjoying. All I can say having used these for the last month - my 9 month old sanseveria (which I know are very slow growing) has suddenly taken off, my pothos N'Joy that was a propogation from a friend has had four leaves for 5 months has now got new growth and my going nowhere but not dying syngonium alba also has new growth. Is it the placebo effect and this would have happened with time anyway? I don't know ! but I do know that after months of nothing and in a time plants should be slowing down I introduced Dyna-Gro ProTeKt silicon supplement and GT foliage focus and my most sluggish plants have taken off. I'm convinced.
