The NZ supplier of Dyna-Gro may be sold out for some time sorry. They have not provided a date for when they might be back in stock.  

Plants can't wait? Have a look at GT Silica instead (same source of silicon as ProTekt).

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. But indoors? Our plants rely on us to boost the silicon their soil is missing, so they can protect themselves the way nature intended. 

What does Pro-Tekt do?

PROTECTS: Source of silicon 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 level. Silicon 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. 

*IMPORTANT*

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 nutrients. 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.
