PPM (Parts Per Million) 🌱

In RDWC systems, PPM is everything! Make sure to start out right, by using clean water, such as distilled.

Overall, PPM measures the concentration of nutrients in your solution, making sure plants get the right balance at every growth stage.

During a grow, adjusting the height of your lights is crucial to support healthy plant development! 

🔆 Vegetative stage: Lights should be lower for more intensity, encouraging growth. 
🔆 Flowering stage: Gradually raise the lights to prevent light burn and focus energy on bud development. A good rule of thumb is 18-24" above the canopy at all times and if you're serious about your lighting, we suggest a PAR meter to assure your plants are at a comfortable lighting.

As your plants grow taller, your lights should be adjusted accordingly 💡

Oxygenation 🌬️

In hydroponics, oxygenation is the process of enriching the nutrient solution with dissolved oxygen to support healthy root respiration and plant growth.

Tools like Hydra Venturi Circulators help maximize oxygen levels, so plants thrive with each cycle! 🌱💧

How is Hydra Unlimited using Media-Less Growing? 🌱

With our patented Root Halo media-less Snap-In Netpots, you no longer need a traditional grow media to anchor or help saturate your roots. We developed a reusable base that utilizes a neoprene collar to hug your plant, while roots are suspended down into your water and nutrient solution.

This approach minimizes waste, reduces the risk of pests and diseases associated with soil, and enhances oxygen availability to the roots, promoting faster growth and higher yields in a clean, controlled environment.

This provides the perfect environment for roots to thrive in, and is one of the easiest and cost-effective upgrades a grower can make. Healthier roots, lower costs, and a cleaner grow environment—this is hydroponics done right!

Find the Right Water Level! 🌊

When starting out, it's easy to go overboard on water levels—but less is more! Aim to keep water just touching the roots without soaking the whole stalk or media. This helps roots breathe and prevents early issues, setting your grow up for success. 🌱💧

Here is a quick video and visual guide: https://www.youtube.com/watch?v=x8I-ET0eJz8&t=2s
