In the world of hydroponic gardening, much of the conversation centers on the essential primary and secondary nutrients. We meticulously balance nitrogen, phosphorus, and potassium, and ensure our micronutrients are in check. But there is a powerful, often overlooked element that can fundamentally change the health and resilience of your plants: silica. The Role of Silica in Plant Structure Silica is not classified as an essential nutrient, yet its impact on plant health is significant. When plants absorb silica, it is deposited into the cell walls of leaves, stems, and roots. This process creates a physical barrier that strengthens the plant's entire structure. Consider a plant without adequate silica—its stems may be thin and its leaves prone to wilting under stress. Now, visualize that same plant with silica-fortified cell walls. The structure is reinforced, much like rebar within concrete. This internal strengthening makes the plant better equipped to handle environmental stresses like heat and drought, and provides a physical defense against pests and fungal diseases. The hardened cell walls are difficult for pests like spider mites to penetrate, and they can inhibit the spread of common issues like powdery mildew. A Strategic Approach to Application Timing is crucial when integrating silica into your nutrient regimen. For maximum benefit, it should be introduced early and consistently. I recommend starting with a low dose during the vegetative growth phase and continuing its use throughout the flowering or fruiting stage. This allows the plant to build a robust internal structure from the very beginning. When adding silica to your reservoir, it is important to add it first. Silica products typically have a high pH and will raise the pH of your water. Adding it first allows you to adjust the pH back into the optimal range (typically 5.5 to 6.5) before adding your other nutrients. This prevents any potential issues with nutrient availability or precipitation.

I made this video hoping to help people understand all of the crazy acronyms surrounding hydroponics and indoor gardening. A few of these I went over yesterday, but I hope there are at least a few that will be new to you :)

So, we all know hydroponics works to grow leafy greens and some fruiting plants like tomatoes. Has anyone ever tried to grow cabbage or cauliflower? What about asparagus? Or grains like oats or rice or quinoa? Horseradish? Ginger? Onions? Rhubarb? How did it turn out? Is there a favorite crop that you dream about growing? Peanuts?🤔🧐 Cotton?

Hi all just started and I have never gardened before. Just wondering what the start up costs could potentially range from. Looking at some of the posts it seems like it could add up quickly. Also it seems as though you need a range of lights for various wavelengths. Any suggestions? Thanks!
