Canna Flush – The Ultimate Flushing Agent for Cleaner Buds & Better Taste

Canna Flush is the definitive solution for growers who demand the cleanest, best-tasting harvests possible. This specialized flushing agent is designed to strip away excess nutrients and salts from your root zone, resetting your medium and allowing your plants to finish strong with unparalleled purity in their flavor profile.

Ever opened a jar of your hard-earned bud only to be greeted by a harsh, chemical aftertaste that masks the natural terpenes? That's the signature of nutrient lockout and salt buildup—a silent killer of quality that happens when your medium becomes saturated with unused minerals. It's frustrating, wasteful, and completely avoidable. Without a proper flush, you're essentially smoking the leftover fertilizer, not the fruit of your labor.

Before Your Final Flush: The Setup for Success

Integrating Canna Flush into your routine is straightforward, but timing is everything. You'll primarily use it in two scenarios: to correct an overfeeding issue mid-grow, or to execute a pristine pre-harvest flush. For the legendary final cleanse, plan to start your flush about 10-14 days before your planned harvest date. Have your pH-balanced water ready and your feeding schedule paused.

• Gather your tools: You'll need your mixing bucket, a reliable pH meter, and of course, your bottle of Canna Flush.
• Check your runoff EC: Before you start, test the EC of your runoff water. This gives you a baseline of the nutrient concentration in your medium.
• Mix at the correct ratio: For a pre-harvest flush, use 5ml of Canna Flush per litre of water. For correcting overfeeding, use 2ml/L for soil and 4ml/L for hydroponic systems.
• pH your solution: Always adjust your flushing solution to the ideal pH for your medium (5.5-6.5 for coco/hydro, 6.0-6.8 for soil) to ensure maximum effectiveness.

During the Flush: Resetting the Root Zone

This is where the magic happens. As you water with the Canna Flush solution, it acts like a magnet for excess mineral salts. It chelates and mobilizes them, pulling them out of the medium and into the runoff water. You're not just drowning your roots; you're actively cleansing their environment. For a pre-harvest flush, apply the solution for the first 3-5 days of your flush week. You'll likely see a significant drop in runoff EC after the first couple of applications. Follow this with plain, pH-adjusted water for the remaining days until harvest. Watch as your plants naturally begin to fade, pulling the last of the stored energy from their leaves—a sign they're finishing clean.

After the Flush: The Reward of Purity

Once you've completed the flush and harvested, the difference is in the dry and the smoke. Properly flushed buds burn to a clean, white ash, a telltale sign of minimal mineral content. The smoke is smoother, less harsh on the throat, and the true flavor and aroma of the strain shine through without any chemical interference. Many growers also use Canna Flush to cleanse and rebalance their medium between grows, especially when reusing soil or coco, saving money and creating a blank slate for the next cycle.

Short- and Long-Term Advantages and Benefits

• Immediate Problem Solver: Quickly corrects overfeeding and nutrient lockout, getting stressed plants back on track.
• Enhanced Final Taste: By removing stored nutrients, you taste the plant's natural terpenes, not the fertilizer.
• Smoother Smoke: Flushed buds burn cleaner, resulting in a less harsh and more enjoyable experience.
• Medium Rejuvenation: Cleanses soil, coco, or hydroton of salt buildup, making it ready for reuse or rebalancing.
• Microbe-Safe Formula: Unlike harsh chemical flushes, it won't harm the beneficial bacteria and fungi in your living soil.
• Universal Application: Works effectively in all growing media—soil, coco coir, and hydroponic systems.
• Precision Tool: Allows for a controlled, effective flush without the guesswork and massive water waste of traditional methods.
• Quality Assurance: An essential step for commercial and hobbyist growers alike who prioritize top-shelf end product quality.

Frequently Asked Questions

When should I use Canna Flush?

Use it to correct overfeeding symptoms at any stage, or for a controlled pre-harvest flush starting 10-14 days before chop. It's also great for cleaning mediums between grows.

How do I use it for a final flush?

For the last week, feed with a solution of 5ml Canna Flush per litre of water for the first 3 days. Then, finish with plain pH-adjusted water for the remaining 4 days before harvest.

Is it safe for my organic living soil?

Yes! Canna Flush is designed to be gentle and will not harm the beneficial microbial life in your soil. It only targets excess mineral salts.

Can I use it in my hydroponic system?

Absolutely. Use at a rate of 4ml per litre to correct overfeeding in recirculating or drain-to-waste hydro systems. It helps clear salt buildup from lines and reservoirs.

How is this better than just using lots of plain water?

Plain water alone can take 3-5 times the pot volume to achieve what Canna Flush does in 1-2 passes. It's more effective, uses less water, and is less stressful on the plant's root system.

Personal Experience of Pevgrow’s CEO (Alan)

Let me be real with you—I used to hate flushing. The mess, the gallons of runoff, the uncertainty. I'd just drown my pots in water and hope for the best. Then I tried Canna Flush, and it changed my end-game completely. Now, my routine is dialed. About 10 days before I plan to harvest, I stop all base nutrients. For the next three waterings, I mix 5ml of Flush per litre, pH it to 6.3 for my soil, and give each plant a good soak until I see about 20% runoff. I watch the runoff EC plummet after the second application—that's how you know it's working. I then switch to plain pH'd water for the final few days. The difference in the final cure is night and day. The smoke is unbelievably smooth, and the terpene profile on strains like our Lemon Cherry Gelato or Zkittlez comes through with crystal clarity, no chemical backnote. It's the final polish that turns great bud into legendary bud. I also keep a bottle on hand for those "oops" moments—if I ever get heavy-handed with the bloom boosters, a single treatment with Flush at 2ml/L gets everything back in balance without missing a beat. It's not just a product; it's an insurance policy for your harvest's quality.
