Types of Hydroponic Systems
With hydroponic systems, there are 2 main categories: Drain to Waste and Recirculating. The most popular recirculating hydroponic systems used in the grow room are the DWC (Deep Water Culture), Ebb & Flow, and Drip Emitters. There are also passive, wick based hydroponic systems available, but we are only going to cover the more popular systems to help save you some time.
The systems below are very common and easily found at local hydroponics shops. General Hydroponics, Flo-n-Gro, Current Culture H2O and Hydrofarm Active Aqua are the manufacturers that we have become familiar with over the years and all offer quality products that are easy to set up and get you growing quickly. Your budget may dictate which system is the right solution for you. The Current Culture H2O systems is the most advanced and most expensive setup. The Hydrofarm Active Aqua Root Spa system is the most budget friendly. Both the Flo-n-Gro and the General Hydroponics waterfarm setups are mid-range systems offering a good balance in cost and features.
Current Culture H2O - Under Current DWC Hydroponic Systems
The Under Current® system is the world’s only recirculating water culture hydroponic system to feature our patented Sub-Current Culture® circulation method. Sub-Current Culture® (SCC) technology utilizes negative water pressure to recirculate highly oxygenated nutrient solution through the plant’s root zone. This continuous fluid motion supercharges the nutrients with dissolved oxygen, creating hyper-aerobic conditions perfect for explosive plant growth. Constant 24/7 nutrient circulation ensures pH and EC levels are uniform throughout the entire system.
Our unique water culture application is unprecedented in layout versatility and ease of use. The Under Current® consistently delivers awe-inspiring yields for any sized application, from hobby to commercial greenhouse.
Under Current System Features:
- Modular Design
- Multiple growth module sizes and plant spacing options
- Easy to set up, break down and expand
- 60+ system configurations to suit any size plant and grow space
- Designed to accommodate a wide variety of lighting footprints

Just set the fill and drain cycles, and the controller unit does the rest!
As for safety, the Grow Flow is the only unit available with fail-safe overflow protection. If the float valve stops operating, the LED indicator lights up on the control panel and the emergency shut-off valve automatically shuts down the system, preventing any spillage or damage to your growing area.
