Pro Silicate by Grotek is the structural reinforcement your crop needs to transform from fragile to indestructible. This additive, rich in silicon, calcium, and potassium, is designed to harden cell walls, ensuring your plants can support the weight of massive buds while creating a natural shield against external threats.
Many growers focus solely on NPK and boosters to fatten buds, forgetting the skeleton that has to support all that weight. You might have experienced the frustration of seeing a spectacular branch snap under its own weight just weeks before harvest, or watched your plants wilt helplessly during a sudden heatwave because they lack internal hydration retention.
Ignoring the structural health of your crop is a ticking time bomb. Weak stems mean you have to use stakes and nets everywhere, complicating your work. Furthermore, a soft cell wall is an open invitation for sucking insects and fungi to penetrate your plant's tissue effortlessly. Basically, without silicon, your plants are fighting the elements naked.
The solution is to integrate Pro Silicate into your feeding chart. By hardening the cell membranes, this supplement acts like a bulletproof vest for your weed. It not only allows the branches to hold heavy flowers without bending but also makes the plant less appetizing to pests and much more resistant to dehydration.
If you grow in Hydroponic and Aeroponic Systems or inert substrates like coco coir, Pro Silicate is not optional; it is mandatory. These environments usually lack silicon naturally. Without it, plants grow fast but often weak and "lanky."
By adding this Grotek supplement, you artificially provide that missing element found in the earth's crust. The result is a hydroponic crop with the structural robustness of a soil-grown plant, capable of pumping nutrients at full speed without collapsing.
For the outdoor grower battling the elements, this product is your best ally. Intense sun, strong winds, and temperature fluctuations can ruin a harvest. Pro Silicate improves the plant's water management, preventing it from losing moisture too quickly through transpiration.
It creates a physical barrier. When insects try to bite a leaf treated with silicon, they find a much harder surface, often discouraging them from establishing a colony. It's a clean way to reduce the need for harsh Insecticides cannabis later on.
Not sure if you need to add silicon to your mix? Check these points to see if it fits your style:
Add 0.5 ml per liter of water during the vegetative stage and early flowering. It is crucial to add it to the water before any other nutrient to avoiding precipitation (cloudy water).
Yes, and it works great. Mix 0.5 ml to 1 ml per liter of water and spray the leaves on both sides. Do this in low light conditions (when lights go off or at sunset) to avoid burns.
Yes, Pro Silicate is alkaline and will raise the pH of your nutrient solution. Always check and adjust the pH after adding it to your tank.
You can use it throughout the vegetative phase and up to the mid-flowering stage. It is recommended to stop a few weeks before harvest to ensure a clean flush.
I consider silicon one of the "secret weapons" of veteran growers. I personally use Pro Silicate mainly in summer crops or when I know the temperatures are going to spike. The difference in how the leaves stand up to the heat is night and day compared to untreated plants. Also, if you are doing LST (Low Stress Training), using this product helps the stems recover and harden much faster in the new position. A must-have in my arsenal.
