Growth Technology

Growth Technology pH Probe Cleaner is a specialised cleaning solution developed for safe and effective cleaning of pH probes and electrodes, suitable for BLuelab and Milwaukee. It removes accumulated mineral salts, nutrient residues and organic contaminants that can affect measurement accuracy. Regular use extends the life of pH electrodes and maintains maximum measurement accuracy.

Every pH electrode gradually becomes contaminated during use, especially when measuring nutrient solutions, water with high mineral content or organic solutions. Deposits on the sensitive membrane can lead to a slower response, inaccurate measurements and difficult calibration.Growth Technology pH Probe Cleaner was developed specifically to safely remove these contaminants without damaging the electrode's sensitive structure.

Regular cleaning restores the probe's response speed, improves measurement accuracy and reduces the need for premature electrode replacement. The manufacturer recommends that, after each cleaning, the probe be recalibrated using pH 7.0 and pH 4.0 buffer solutions to ensure the most accurate results.

Growth Technology pH Probe Cleaner is suitable for all Bluelab pH probes and pH meters, including Milawaukee and those from other manufacturers.

📋 Instructions for use

1. Rinse the pH probe with clean water.
2. Apply a small amount of Growth Technology pH Probe Cleaner to a soft brush or directly onto the electrode.
3. Carefully clean the glass membrane without applying excessive pressure.
4. Rinse thoroughly with clean water.
5. Store the probe in pH Probe Refill and Storage.
6. Before the next use, calibrate with pH 7.0 and pH 4.0 buffer solutions.

⚠️ Important: Never store a pH electrode in distilled or deionised water. After cleaning, use pH Probe Refill and Storage to prevent the sensitive membrane from drying out and maintain measurement accuracy.

💡 Urban Botaniks tip: Clean the pH probe regularly, especially when working with nutrient solutions high in minerals. Combining pH Probe Cleaner, pH Probe Refill and Storage and regular calibration significantly extends the electrode's life and ensures reliable measurements with every use.

Spidermite Control - the natural insect eliminator.

• 100% organic
• 100% safe
• 100% control
• helps against: Powdery mildew*
• effective against: Spider mites*, Aphids*, Whitefly* and many more
• Enough to make 4 litres of full-strength spray

Why use Spidermite Control?

• Spidermite Control is made from specially blended plant extracts; it is harmless to children and pets and safe for use on edible fruits and vegetables, as well as ornamental plants, from seedling to harvest.
• Spidermite Control will not harm beneficial insects. 
• Spidermite Control is completely safe, leaving no harmful residues; it evaporates as it suffocates and eliminates pests.
• Use Spidermite Control as part of your "Plant Care Programme" to achieve the best results in your home, garden and greenhouse.

How does Spidermite Control work?

• Spidermite Control works through a physical mode of action, blocking pests' respiratory passages and thereby causing death by suffocation.
• Insect eggs are unlikely to hatch because they are encapsulated in the medium and evidently unable to develop successfully into adulthood.

What are spider mites?

• Spider mites are a gardener's enemy. They are a serious pest of both outdoor and houseplants because they are difficult to see before they damage plants. Spider mites gather on the undersides of leaves, suck plant sap and remove chlorophyll. Visible signs include webbing and white or yellow spots on the leaves; defoliation occurs in severe cases. Spider mites are smaller than 1 mm and can vary in colour. They lay small, spherical eggs that are initially transparent, and many species spin webbing around the eggs to protect them from predators. Spider mites are generally more common in hot, dry conditions. Spider mites can hatch within 3 days, reach adulthood in only 5 days, and a female can lay up to 20 eggs per day and live for around 4 weeks. This means that a single adult female can produce a population of one million spider mites in just one month.

Active ingredients:

• 1% Coriander Oil
• 94% Rapeseed Oil
• 5% Triethanolamine

Recommended use:

• Shake well! Dilute 25 ml SMC in 1 litre of water! Spray the upper and lower sides of the leaves with a fine mist! Spidermite Control can be used at all stages of growth.

Growth Technology Root Riot® 77 is a professional tray with 77 organic starter cubes, intended for germinating seeds, rooting cuttings and producing healthy seedlings. The cubes are ready to use and made from finely processed organic material with an excellent water-to-air balance that promotes rapid development of a strong root system. Suitable for growing in soil, coco and hydroponics.

Root Riot® is one of the most preferred media for germination and rooting among professional growers. Thanks to their porous, sponge-like structure, the cubes retain the optimum amount of moisture while providing sufficient oxygen for young roots. This significantly speeds up seed germination and the formation of a healthy root system.

The cubes are made from an organic, composted peat substrate, enriched with biologically active ingredients, micro- and macronutrients that support early plant development. The material is buffered so that pH and EC remain stable even after moistening or using a weak nutrient solution.

Thanks to their excellent structure, roots easily penetrate the cube and continue developing after transplanting without stress. This allows young plants to be moved directly into soil, coco substrate, mineral wool or a hydroponic system without disturbing the root system.

Root Riot® cubes are biodegradable, clean to handle and dust-free, making them exceptionally convenient for both hobbyists and professional nurseries. The manufacturer recommends combining them with Clonex Rooting Gel and Clonex Mist for an even higher successful rooting rate for cuttings.
