💧🌡️ **HYDROPONIC WATER TEMPERATURE – ARE YOU GETTING IT RIGHT?**

One of the most overlooked factors in hydroponics is nutrient solution temperature. Many beginners focus on lighting, nutrients and pH but forget about what's happening around the roots!

✅ **The ideal water temperature is 18–22°C.**

🥶 **Too Cold (Below 18°C)**
- Slower plant growth
- Reduced nutrient uptake
- Potentially lower yields

🔥 **Too Hot (Above 22°C)**
- Less dissolved oxygen available to roots
- Increased risk of harmful bacteria and root disease
- Poorer root health and reduced growth

🌡️ **THE SOLUTION?**

❄️ **Winter:** Use an aquarium-style water heater to maintain consistent temperatures.

☀️ **Summer:** Use a water chiller to prevent your nutrient solution from overheating.

💧 **Don't forget pH!** Temperature changes can influence pH readings and nutrient solution chemistry. Always check your pH regularly.

Healthy roots = Healthy plants = Better yields! 🌱

🌱💨 UNDER-CANOPY AIRFLOW – HEALTHIER PLANTS, STRONGER RESULTS!

Good airflow isn't just about moving air above your plants. What's happening under the canopy is just as important!

💨 Inline Fans + Coolsox = Smarter Air Distribution

Inline fans provide the airflow, while Coolsox perforated air-distribution ducting spreads that air evenly along the length of your grow trays.

Positioned beneath the canopy, this combination helps eliminate stagnant air pockets and creates a more consistent growing environment.

✅ Improved Air Circulation – Moves air through the lower canopy where traditional fans often struggle.

✅ Better Humidity Management – Helps reduce pockets of trapped moisture around foliage.

✅ Reduced Disease Pressure – Improved air movement can help lower conditions favourable to mould and fungal diseases.

✅ Stronger Plants – Gentle, consistent airflow supports healthy stem development.

✅ More Uniform Conditions – Distributes air along the entire tray rather than concentrating it in one spot.

Whether you're running a small grow room or a commercial facility, getting your under-canopy airflow right can make a big difference.

CO₂ CONTROL FOR SEALED GROW ROOMS 🌱💨
In a sealed room, CO₂ isn’t something you want to guess — accurate monitoring and controlled delivery are essential.
A quality CO₂ meter/controller paired with a regulator lets you automatically maintain your target CO₂ concentration throughout the lights-on period.
✅ Accurate CO₂ monitoring — know your actual PPM in real time
✅ Automatic control — switches CO₂ delivery on and off around your set point
✅ Consistent environment — reduces large swings in CO₂ concentration
✅ Better use of supplemental CO₂ — controlled delivery helps reduce unnecessary gas wastage
✅ Supports higher photosynthetic demand — particularly in high-light, well-controlled environments
✅ Ideal for sealed rooms — where temperature, humidity, lighting and CO₂ can all be managed together
Once you move into a sealed environment, CO₂ becomes another parameter to measure and control — just like temperature, RH, VPD and light.

💧 Using tank water for your grow?

Rainwater can be a great water source — often with a low starting EC — but clear water doesn’t always mean clean water.

Tank water can contain bacteria, pathogens, sediment and organic matter, and its pH and mineral content can vary considerably.

🌧️ Keep gutters clean
💧 Use a first-flush system
🧹 Maintain and clean your tank
🧪 Most importantly — get your tank water tested.

Knowing what’s actually in your source water can save a lot of headaches when diagnosing plant and root-zone problems.

There’s nothing wrong with a grow tent. In fact, a well-dialled tent can produce seriously good results. 👌🌱

But moving from a tent into a properly designed **sealed room with CO₂** is a whole different ball game.

Think of it like going from an old Holden to a Ferrari. 🏎️💨

The Holden will get you there — and it can do a bloody good job.

But the Ferrari? Everything is supercharged.

In a sealed room you’re taking much greater control over the entire growing environment — temperature, humidity, airflow, lighting, irrigation and CO₂.

That extra control allows you to push the room harder and, when everything is properly balanced, achieve faster growth, stronger production, better consistency and potentially much bigger results.

But there’s a catch…

**The faster the car, the more important the driver becomes.**

Once you start pushing higher light levels and elevated CO₂, mistakes with temperature, humidity, irrigation or nutrition can become much more noticeable.

A sealed room isn’t just about adding CO₂. It’s about getting the **whole system working together.**

Tent growing teaches you how to drive.

A sealed CO₂ room lets you put your foot down. 🚀

02/09/2026

Whitefly can become a serious problem fast — especially in warm, protected growing environments.
A good Integrated Pest Management (IPM) program is about getting on top of the problem before populations explode.
🔍 MONITOR
Check the undersides of leaves regularly and use yellow sticky traps to detect adult whitefly early.
🐞 USE BENEFICIALS
Biological controls available in Australia include Eretmocerus hayati and Montdorensis predatory mites, including slow-release sachets. Introducing beneficials early gives them the best chance of establishing before pest pressure becomes heavy.
🎯 TARGET
If whitefly numbers start increasing, use appropriate, label-approved treatments. Remember — eggs and immature whitefly are predominantly found on the undersides of leaves, so good coverage matters.
🔄 ROTATE
Whitefly can develop insecticide resistance. Avoid repeatedly using the same mode of action and follow resistance-management recommendations and product labels.
🧹 PREVENT
Keep growing areas clean, remove heavily affected leaves and weeds, maintain good airflow and continue monitoring even after populations decline.
The key is simple: find them early, manage them early, and don't rely on one control method.

🌱 SPRING IS COMING — TIME TO GET READY FOR OUTDOOR SEASON!
As the days get longer and temperatures start climbing, now is the time to start preparing for the outdoor grow season.
Rhizo Pots & Geo Pots are two of our most popular choices for growers wanting a larger, healthier root zone without the problems associated with traditional solid pots.
🌿 Why use breathable pots?
✅ Improved oxygen around the root zone
✅ Excellent drainage
✅ Helps prevent circling and root binding
✅ Encourages natural air pruning
✅ Stronger, more fibrous root development
✅ Reusable and built for serious outdoor growing
Geo Pots are heavy-duty fabric containers available in large sizes and are a great option for growers wanting maximum root volume.
Rhizo Pots provide excellent aeration and drainage while encouraging roots to branch throughout the growing medium rather than circling around the container.
Whether you're growing in soil or coco, getting the root zone right from the beginning can make a massive difference later in the season.
☀️ Spring is coming. Get prepared early.
Rhizo Pots & Geo Pots in stock now at The Grow Shop Coffs Harbour.
