Startrex BioTabs is the ultimate 100% organic soil improver and probiotic fertilizer, designed to bring your tired, lifeless soil or coco back to life with a powerful kick of beneficial bacteria and essential nutrients. It's the secret weapon for growers who want explosive root growth, superior nutrient uptake, and a thriving, living ecosystem right in their pots.
Ever feel like your plants are just going through the motions? You water them, you feed them, but they never seem to reach their full, vibrant potential. The problem isn't you—it's your soil. Most commercial potting mixes are sterilized, which means they're dead on arrival. They lack the microbial life that transforms nutrients into food your plants can actually use. You're left feeding a ghost town, wondering why your growth is stunted and your yields are just... meh.
It's frustrating, right? You invest in quality seeds and top-shelf nutrients, only to have your efforts bottlenecked by inert substrate. Your plants struggle to establish, roots stay weak, and you miss out on the explosive vegetative growth and heavy flowering you know is possible. You're not growing in soil; you're growing in dirt.
That's where Startrex comes in. This isn't just another additive; it's a soil resurrection kit. By mixing Startrex into your medium, you're inoculating it with a massive army of probiotic soil bacteria and fungi. These microscopic allies immediately get to work, breaking down organic matter and unlocking nutrients, turning your substrate from a passive holder into an active, living partner in your plant's success.
Startrex is a concentrated, 100% certified organic powder with an NPK of 3-1-2. But the magic isn't just in the macronutrients; it's in the living components and powerful carriers.
Imagine a grow where your plants explode out of the gate. Seedlings establish faster, clones root with vigor, and your vegetative plants become lush, green monsters. With Startrex, you're not just feeding the plant; you're feeding the soil ecosystem that feeds the plant. This creates a self-sustaining loop of health and vitality. Your nutrient schedule becomes more efficient because every drop of fertilizer is fully utilized. You'll see stronger stems, denser foliage, and a root zone so healthy it's practically buzzing with life. The best part? This benefit extends through the entire cycle, leading to more robust flowering and ultimately, better yields.
Startrex is the perfect foundation for a complete living soil system. For the ultimate organic setup, combine it with other microbial powerhouses and natural fertilizers from our catalog.
For new soil/coco: Mix 2 tablespoons (approx. 25g) into every 5 liters of substrate. For reusing old medium: Remove the top 5cm of old soil, clear large roots, leave small ones. Mix 25g of Startrex with 1 liter of new soil/coco and use as a fresh top layer.
Absolutely! Startrex works brilliantly in both soil and coco substrates to introduce beneficial life and improve nutrient dynamics.
Yes, it's very simple to use. Just mix it in as directed. It's a perfect entry point into organic, living soil growing.
You'll notice a difference almost immediately. Plants will show improved vigor, greener growth, and faster root establishment within the first week.
While designed for organic systems, the microbial life and fulvic acid in Startrex can improve the efficiency of any nutrient regimen. However, for best results, follow the complete BioTabs organic method.
Let me be straight with you: I used to be a "sterile medium" guy. I thought keeping everything clean and controlled was the key. Then I tried Startrex on a batch of clones I was struggling with. The difference was night and day. The ones in the Startrex-amended coco exploded with white, fuzzy roots in days, while the control group just sat there. It was a lightbulb moment.
Now, I won't start a single plant—whether it's a prized cannabis cut or a tomato seedling for my garden—without mixing in Startrex. It's like giving your plants a probiotic smoothie for their roots. The substrate feels alive, and the plants just look happier and more robust. My top tip? Don't skimp on it when reusing soil. That old, spent mix from last run? A healthy dose of Startrex brings it back to life better than any flush or recharge product I've tried. It's the cornerstone of my organic grows and the first thing I recommend to anyone wanting to move away from chasing pH and EC and towards growing with the soil, not just in it.
