No more guessing, no more deficiencies. Just healthy, vibrant growth and the kind of yields that make your inner grower grin.

Frequently Asked Questions

What is the ideal pH range for cannabis?

For soil, aim for 6.0–6.5. In coco or hydro, keep it between 5.5–6.0. Plagron pH Plus helps you hit and maintain that target every time.

Can I use pH Plus with organic nutrients?

Absolutely. It’s fully compatible with organic, mineral, and hybrid feeding programs—just adjust after adding your nutrients.

How much pH Plus should I use?

Start with 0.5 ml per liter and adjust gradually. Always use a calibrated pH meter. The exact amount depends on your water and nutrient load.

Is potassium hydroxide safe for plants?

Yes—when used correctly. KOH is a common and effective pH adjuster. It also supplies potassium, a macronutrient your plants need in large amounts, especially during flowering.

Can I use it in DWC or recirculating systems?

Yes. Its clean, low-foam formula works perfectly in hydro setups. Just monitor pH daily and adjust as needed.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve tried a dozen pH adjusters over the years—from generic lab chemicals to fancy organic blends. But Plagron pH Plus is the one I keep coming back to. When I’m helping a friend set up their first grow tent, I hand them this bottle and say: ‘Start with one drop per liter, test, and adjust.’ It’s that simple.

For my own grows, I use it in both soil and coco. I love that it adds potassium—especially during flowering, when demand spikes. I’ve seen fewer deficiencies and denser buds since switching. Yes, it’s caustic (wear gloves!), but so is every pH Up. The difference? Plagron works fast, lasts long, and doesn’t gunk up my lines. If you’re serious about growing, this isn’t a luxury—it’s a necessity.
