Hesi pH+ Plus – Premium pH Up Adjuster for Hydroponic & Soil Cannabis Cultivation

Hesi pH+ Plus is the definitive tool for mastering one of the most critical aspects of indoor cultivation: water pH management. This concentrated potassium hydroxide solution gives you precise control to raise the pH of your nutrient mix, ensuring your plants live in their perfect environment for explosive growth and bountiful harvests.

Ever feel like you're feeding your plants a gourmet meal, but they're just picking at it? That's the frustration of pH imbalance. Your nutrient solution could be packed with everything they need, but if the pH is off, it's like the door to the pantry is locked. Your plants show signs of hunger—yellowing leaves, stunted growth, weird deficiencies—even though you're pouring in the good stuff. This silent thief steals your time, your nutrients, and ultimately, your yield, leaving you guessing and stressing instead of enjoying the grow.

The Home Grower's Secret Weapon

For the hobbyist with a tent in the spare room or a dedicated cabinet, pH+ Plus is your stability anchor. You're not running a commercial lab; you need simplicity and reliability. Mixing your nutrients in a bucket or reservoir, you test the pH and see it's too acidic—maybe your tap water is soft, or the nutrients themselves lower the pH. A few drops of pH+ Plus, a gentle stir, and you're back in the perfect 5.8-6.2 range for hydroponics or 6.0-6.5 for soil. No more guessing, no more panic. It turns a potentially complex chemistry problem into a quick, one-step fix, letting you focus on training, defoliating, and watching those buds swell.

The Hydroponic Pro's Precision Tool

If you're deep into DWC, RDWC, or NFT systems, precision isn't just nice—it's everything. Your plants' roots are bathing directly in the nutrient solution 24/7. A pH swing here isn't a minor issue; it's a root-burning, growth-stopping crisis. Hesi pH+ Plus offers the exact, predictable adjustment you need. Its potassium hydroxide formula is clean and highly soluble, allowing for minute, controlled adjustments without throwing your carefully calculated EC/PPM readings wildly off track. It integrates seamlessly into your automated dosing systems or manual checks, providing the rock-solid stability that high-performance hydroponics demands for those record-breaking yields.

How to Choose Your pH Management Strategy

Wondering if you need this in your arsenal? It's simpler than you think.

• If you check your water's pH and it consistently reads below 5.5 (for hydro) or 6.0 (for soil) after adding nutrients, you need pH+ Plus.
• If you use reverse osmosis (RO) water, which is naturally acidic, pH+ Plus is non-negotiable.
• If you see recurring nutrient deficiencies (like calcium or magnesium lockout) despite feeding correctly, a pH issue is likely the culprit.
• If you value predictability and want to eliminate one of the biggest variables in plant health, keeping a bottle of pH+ (and its counterpart, Hesi pH- Minus) on hand is a smart move.
• If you're a beginner, mastering pH is your first step toward pro-level results. Start with the right tools.

Advantages and Benefits You'll See Immediately

• Precise Control: Potassium hydroxide allows for fine, drop-by-drop adjustments, giving you total command over your solution's acidity.
• Optimal Nutrient Uptake: By locking pH into the ideal range, you unlock 100% of the potential from your base nutrients and boosters, like Hesi Bloom Complex.
• Prevents Deficiencies: Stops nutrient lockout before it starts, eliminating those confusing yellow patterns and purple stems caused by pH-induced hunger.
• Clean Formula: Designed to work seamlessly with the rest of the Hesi line and other major brands, without causing nutrient precipitation or gunking up your system.
• Boosts Plant Vitality: Happy roots in a stable pH environment translate to explosive vegetative growth and dense, resinous flowers.
• Saves Money: Stops you from wasting expensive nutrients that your plants can't absorb. Every milliliter of feed goes to work.
• Foundation for Success: It's the unsung hero that makes all your other efforts—from perfect lighting in your grow tent to dialed-in climate control—actually pay off.

Frequently Asked Questions

How do I use Hesi pH+ Plus?

Always add your nutrients to water first and mix thoroughly. Then, test the pH. If it's too low (acidic), add pH+ Plus drop by drop, stirring well after each addition, and re-test until you reach your target range (5.8-6.2 for hydro, 6.0-6.5 for soil). Start small—it's powerful!

Can I use it with organic nutrients?

Yes, absolutely. While many organic soils have buffering capacity, if you're mixing liquid organic feeds or using coco, pH management is still crucial. pH+ Plus will work effectively.

What's the difference between pH+ and pH-?

pH+ (this product) raises pH. Hesi pH- Minus lowers pH. You need both in your toolkit because your starting water and nutrient mix can swing in either direction. They are the yin and yang of perfect cultivation.

How often should I check and adjust pH?

In recirculating hydroponic systems, check daily. In soil or drain-to-waste coco, check every time you mix a fresh batch of nutrients. pH can drift over time, especially as plants absorb ions.

Is it safe for my plants?

When used as directed—adding small amounts to your nutrient solution, not directly to plants or soil—it is perfectly safe and is a standard practice in professional horticulture.

Personal Experience of Pevgrow’s CEO (Alan)

Let's be real: for years, I was the guy who thought, 'My tap water is fine, how off can it be?' Then I wondered why I kept getting random calmag issues. pH+ Plus was the game-changer. I keep a bottle right next to my mixing station. My process is simple: fill the reservoir, add my base feed and additives, give it a good stir, then test. Nine times out of ten, especially with our soft local water and potent nutrients, the pH needs a nudge upwards. A few drops of this, stir, test again—bam, 5.9. Perfect. It's eliminated one of the biggest guesswork factors from my grow. I don't run complex hydro; I'm a coco guy. But even in coco, stability is king. This bottle gives me that stability. My advice? Don't see it as an extra expense; see it as an insurance policy for every other euro you spend on seeds, lights, and nutrients. Pair it with a decent pH pen (calibrate it regularly!), and you've just leveled up your grow game significantly.
