Bio-Nova pH- Liquid pH Down, 1 Litre – Premium pH Regulator for Cannabis Nutrient Solutions

The Bio-Nova pH- Liquid pH Down is your essential, no-nonsense tool for dialing in the perfect nutrient environment for your cannabis plants, ensuring they can absorb every last drop of goodness you feed them.

Ever feel like you're pouring love, light, and expensive nutrients into your plants, only to watch them struggle with weird deficiencies? You check your feed chart, you've got the best cannabis fertilizers, but something's off. The problem isn't what you're feeding them; it's whether they can actually eat it. When your water's pH is out of whack, it's like serving a gourmet meal but locking the fridge – all the nutrients are there, but your plants just can't get to them. This leads to stunted growth, yellowing leaves, and a harvest that's a shadow of what it could be. It's frustrating, wasteful, and totally avoidable.

That's where the chaos begins. You start chasing deficiencies with more additives, complicating your mix, wasting product, and potentially making things worse. Your grow room becomes a chemistry lab of guesswork instead of a zen garden of growth. You're left with weak plants, underwhelming buds, and the nagging feeling you're missing a fundamental piece of the puzzle.

Enter Bio-Nova pH-: the simple, powerful solution to end the pH guessing game. This concentrated 24.5% phosphoric acid solution is your precision instrument for lowering pH. A few drops are all it takes to bring your nutrient solution into the sweet spot (5.5-6.5 for most substrates), instantly making all those premium nutrients bioavailable. It's the key that unlocks the fridge, letting your plants feast and thrive.

From Complicated Chemistry to Simple Success

Forget juggling a dozen bottles trying to fix problems caused by incorrect pH. Bio-Nova pH- tackles the root cause. It works seamlessly with any nutrient line, whether you're in soil, coco coir, or a full hydroponic system. By centralizing your pH control with this one reliable product, you eliminate a major variable and simplify your entire feeding routine. No more second-guessing, just consistent, predictable results.

Frequently Asked Questions

Is Bio-Nova pH- really all I need for pH control?

For lowering pH, absolutely. It's a concentrated, reliable acid. You will also need a quality pH meter to measure your levels accurately. For raising pH, you would need a separate pH+ product.

Can I use it in both growth and flowering stages?

Yes, you can use Bio-Nova pH- from the first week of growth right up until one week before harvest. Just remember a proper flush is mandatory before harvest when using any pH adjusters.

How do I know how much to use?

Start with 2-4 ml per 10 litres of water, but this varies greatly depending on your water's starting pH and nutrient concentration. Always add slowly, stir thoroughly, and measure with your pH meter after each adjustment until you reach your desired level.

What if I accidentally add too much and pH goes too low?

If you overshoot, you'll need a pH+ product (like Bio-Nova pH+) to raise it back up. This is why the "add slowly and re-test" method is crucial.

Does it store well?

Yes, keep the bottle tightly sealed in a cool, dark place. The concentrated formula has a long shelf life.

Personal Experience of Pevgrow’s CEO (Alan)

Look, I've been there – staring at a plant showing every deficiency in the book despite feeding it a cocktail of the best boosters. It's maddening. For years, I treated pH adjustment as an afterthought, something I'd do if I remembered. That changed when I started treating it as the first step, not the last. Keeping a bottle of Bio-Nova pH- and a calibrated meter on my mixing station transformed my consistency. My advice? Don't view pH- as just another bottle; view it as the conductor of your nutrient orchestra. It doesn't play the music, but it makes sure every instrument (nutrient) is heard. My routine now is dead simple: mix, measure, adjust with a few drops, water. The difference in plant vitality and my own peace of mind was night and day. It's one of the few products I consider truly non-negotiable for a clean, professional, and stress-free grow.
