BioBizz Bio·Down is the organic grower's secret weapon for perfect pH control, a gentle yet effective solution crafted from nature's own citric acid to keep your nutrient uptake on point without compromising your soil's life.

Ever feel like you're fighting your water instead of growing your plants? You mix your nutrients perfectly, only to watch your girls show signs of lockout a week later—yellowing leaves, stalled growth, the whole frustrating saga. It's usually your pH playing tricks on you, creeping up and locking away the food your plants desperately need. That alkaline swing doesn't just stress your plants; it wastes your time, your effort, and your precious nutes.

This constant battle creates a cycle of guesswork and corrective flushes that can devastate your soil's ecosystem. Harsh chemical pH adjusters might fix the number, but they scorch the beneficial bacteria and mycorrhizae that are the heart of a living organic soil. You end up with a sterile medium, weak plants, and harvests that never reach their full potential. It's the opposite of what organic growing is all about.

Bio·Down ends the war with your water. This isn't a harsh acid; it's a 100% organic pH regulator derived from citrus fruits like lemons. It smoothly lowers your nutrient solution's pH into the optimal 6.2-6.5 range for soil, doing its job effectively while leaving your substrate's micro-life totally unharmed. It's the peace treaty your garden needs.

What it feels like to dial in your pH with Bio·Down

Using Bio·Down is like giving your plants a clear path to the buffet. Suddenly, everything you feed them is actually available. You'll see leaves stay a deep, lush green, growth becomes vigorous and steady, and those worrying deficiency signs just fade away. The best part? You're doing it all naturally. There's a real satisfaction in knowing you're correcting a fundamental issue without introducing a single synthetic chemical into your system. It's the confidence of a dialed-in grower.

The process itself is stupidly simple. No protective gloves, no worrying about fumes—just a few drops, a quick stir, and you're done. It integrates seamlessly with every other product in the BioBizz nutrient line and works in any substrate, making it the universal fix for high pH woes. It's the one bottle that guarantees your carefully selected premium genetics get exactly what they need to express themselves fully.

How to squeeze the most out of your Bio·Down

For flawless pH management, follow these steps:

  1. Mix First, Measure Second: Always add your base nutrients and supplements to your water first. Stir well, then measure the pH.
  2. Start Low, Go Slow: Add Bio·Down drop by drop. A general rule is 0.1 ml per litre to decrease pH by about 0.5 points.
  3. Stir and Re-test: After adding, stir vigorously for 10 seconds and test again. Repeat until you hit your sweet spot (6.2-6.5 for soil).
  4. Use Every Watering: Consistency is key. Use Bio·Down in every feeding from veg through flower to maintain stable root zone conditions.
  5. Pair with a Reliable Meter: Don't guess. Use a quality pH meter and calibrate it regularly for pinpoint accuracy.
  6. Store Smart: Keep the bottle at room temperature and away from direct light to preserve its potency.
  7. Embrace the Full System: For the ultimate organic experience, use it alongside BioBizz Light·Mix or All·Mix soils and their complete nutrient range.

How it fits with other products in your setup

Think of Bio·Down as the essential facilitator in your organic toolkit. It doesn't replace your nutrients; it unlocks them. Whether you're running a simple Grow & Bloom schedule or a full suite with additives like Top Max or Acti Vera, Bio·Down ensures the pH is perfect for uptake. It's the final, crucial step after mixing your nutrient solution, whether you're hand-watering or using a drip system. For growers using hydro or coco, remember the target pH is lower (5.5-6.1), but Bio·Down works there too. It's the universal key to a stable root zone.

Frequently Asked Questions

Is BioBizz Bio·Down really organic?

Absolutely. It's certified for use in organic farming (EU and NOP standards) and is derived from citric acid found in citrus fruits. No synthetic strong acids here.

Can I use it in hydroponics or coco coir?

Yes, you can. While it's especially beloved in soil for its microbe-safe properties, it works perfectly in any growing medium. Just remember to target the appropriate pH range for your system.

How much should I use per litre?

Start with 0.1 ml per litre of water/nutrient mix. This typically lowers pH by about 0.5 points. Always add slowly, stir well, and re-measure. The amount needed can vary based on your starting water quality.

Do I need Bio·Up as well?

It depends on your water source. If your tap water is naturally soft and acidic, you might only need Bio·Down. If it's hard and alkaline, you'll likely use Bio·Down regularly. Bio·Up (a humic acid formula) is for raising pH, which is less common but handy to have on standby.

Will it affect the taste or smell of my final buds?

Not at all. Because it's used in such small quantities and is a simple, natural compound, it leaves no residue or flavour. Your terpenes will be pure and untouched.

Personal Experience of Pevgrow’s CEO (Alan)

Let's be real, I used to hate messing with pH. I'd see the meter drift, panic, and reach for the harsh stuff, only to later wonder why my soil felt dead. Bio·Down changed the game for me. My tap water is a nightmare—hard and alkaline. Now, my ritual is simple: mix my nutes, give it a stir, check the pH (usually around 7.8), and add a few drops of Bio·Down. Watching the digital readout smoothly drop to 6.3 is weirdly satisfying. The difference in the garden is night and day. My plants are calmer, deficiencies are rare, and I know I'm not killing off the life in my All·Mix. The biggest lesson? Don't underestimate the power of getting the basics right. A stable pH is the foundation everything else is built on. My pro tip? Always mix it in a separate container before adding to your reservoir or watering can. It distributes more evenly, and you avoid any hot spots. It's a small step that makes a huge difference.
