Tetra 9 by Agrobeta is the definitive organic flowering booster, a concentrated elixir engineered to transform the delicate transition into bloom into a period of explosive growth and resinous abundance. This isn't just another nutrient; it's a strategic tool that fine-tunes your plant's metabolism to focus all its energy on producing the dense, aromatic, and potent buds you're chasing.
Does your flowering phase feel more like a slow crawl than the explosive sprint you were promised? You feed, you water, you watch... but the buds seem to take forever to stack, and the final aroma lacks that punch you know is possible. It's frustrating to invest weeks of care only to end up with a harvest that's good, but not legendary. That lingering feeling of "what if"—what if the terpenes were stronger, the resin thicker, the yield just a bit heavier—is the gap between a decent grow and a truly epic one.
Agrobeta's Tetra 9 bridges that gap. This meticulously formulated blend of macronutrients, micronutrients, amino acids, humic and fulvic acids, vitamins, and carbohydrates acts as a metabolic catalyst. It tells your plants, "Hey, it's showtime," right when they need to hear it. By applying it just three strategic times, you orchestrate a perfect symphony of growth, directing energy away from unnecessary foliage and straight into bud development, resin gland production, and terpene synthesis. The result? Flowers that don't just grow; they thrive under the spotlight.
Tetra 9 isn't a simple one-trick pony; it's a full-spectrum support system. Its organic composition ensures your buds develop with the cleanest, most natural flavors and aromas possible, avoiding any chemical aftertaste. The key is in the synergy of its components, working together to supercharge your flowering phase.
Imagine your flowering tent not just as a space where buds form, but as a resin factory operating at peak efficiency. From the moment you introduce Tetra 9, you'll notice a shift. The pre-flower stretch becomes more vigorous and organized, with sites for future buds spacing out perfectly. As flowering progresses, the calyxes swell with a noticeable intensity, and a glossy sheen of trichomes begins to blanket every surface. The air in your grow space starts to carry the distinct, complex fragrance of mature terpenes weeks before harvest. Your job shifts from worrying about whether you'll get a good yield to simply watching in awe as the plants do exactly what they're supposed to, but bigger and better.
While Tetra 9 is a star on its own, it shines even brighter as part of a complete regimen. Think of it as the lead guitarist in your nutrient band.
It's simple: three applications total. For indoor grows: 1) 10 days before switching to 12/12 (1.5ml/L). 2) On the day you switch to 12/12 (3ml/L). 3) 10 days after the switch (3ml/L). Outdoors, base it on plant signs: first dose when summer starts and plants begin to stretch, second at first pre-flowers, third 10-15 days later.
Absolutely. Tetra 9 is compatible with soil, coco coir, and hydroponic systems. Its formulation is designed to be readily available to plants regardless of your setup.
Yes, but timing is key. Since autos flower based on age, not light, apply the first dose when you see the first pre-flowers appear, then follow the same 10-day spacing for the next two applications.
On the contrary! Being 100% organic, it enhances the natural terpene profile of your strain, leading to a cleaner, more pronounced flavor and aroma compared to synthetic boosters.
This depends on the size of your garden, but due to the low dosage (max 3ml/L) and only three applications, a single bottle can easily cover multiple plants for an entire cycle, making it extremely cost-effective.
Let me be straight with you: I'm skeptical of magic bottles. But Tetra 9 earned a permanent spot on my shelf. I run a side-by-side test every season, and the difference is never subtle. The plants treated with Tetra 9 don't just flower; they announce it. The stretch is more uniform, the bud sites explode in number, and by week three of flower, the trichome production is visibly ahead. The real win for me is in the dry and cure. The terpene preservation is noticeably better, and that final smoke has a smoothness and flavor depth that's hard to achieve otherwise. My pro-tip? Don't skip the first application 10 days before the flip. That's the secret—it preps the plant's metabolism so when you hit it with the second dose on flip day, it's like lighting the afterburners. I combine it with my standard base nutrient line and a good carbon filter, because once those enhanced terpenes kick in, you'll need it!
