The ALIEN V-SYSTEM puts a new spin on recirculating deep water culture by directly injecting fresh nutrient solution from the header pot to each growing pot virtually simultaneously. This means that when you're adding nutrients or adjusting pH, the system stabilizes- completely mixing the entire volume of nutrient solution- within just a few minutes. Other RDWC systems force the nutrient solution to go through each pot in a row in turn, meaning the system can take half an hour (or much longer!) to stabilize.
The video below shows just how fast the V-SYSTEM stabilizes after adding nutrients or pH adjustments.
