RDWC – Recirculating Deep Water Culture – Medium-less Cultivation Systems
Make growing fun again. Explosive yields with the greatest of ease.
Tired of over complicated irrigation schedules and clogged drippers? Then RDWC is for you.
Trusted by professionals for decades, Recirculating Deep Water Culture has been producing premium quality crops and awe inspiring yields for growers across the globe. Sophisticated enough for those looking to optimize production while still simple enough for the novice hydroponicist, Under Current systems deliver results.
UC systems have been the industry standard for more than 2 decades due to its smart design and ease of operation. Aerated nutrient solution is circulated throughout the system to provide ideal growing conditions for crops ranging from heirloom vegetables to medical cannabis and beyond.
- Media-less growing: No substrate like rockwool, coir, soil, peat or grow rocks is needed.
- Semi-Automated Operation: No timer, scheduling or complications. Keep solution balanced and the system does the rest.
- Redundancy: Water and Air pumps ensure plants are kept in ideal conditions 24/7
- Simple to use: Requires no guess work or crop steering to get great results.
Benefits of RDWC:
-
⚖️ Consistent pH and EC levels across all plant sites.
-
🚀 Fast growth rates due to high oxygen and nutrient availability.
-
🔁 Efficient use of water and nutrients with minimal waste.
-
🧪 Easy to monitor and adjust from one central reservoir.
-
📈 Scalable — great for medium to large commercial grows, especially for high-value crops like cannabis.
Available in a number of configurations to suit various applications, these RDWC systems provide consistent, repeatable results time and time again.
Ideal Plant Spacing for Flower Cultivation:
Quality – RDWC is widely recognized for producing the hydroponic crops with the highest terpene expression and diversity.
Productivity – Hydroponic crop production provides unmatched growth rates, reducing veg times and increasing the number of crop turns per year.
Medialess – Under Current water culture systems require no messy substrates such as rockwool, cococoir or grow rocks, saving on input costs and reducing labor.
