This is the upgrade attachment to the wicking bases from Vivosun, as well as the VGrow smart grow box. Is made to fit a Round Vertical Float Valve and replace the stock refill port. With a very minimal modification, this is a very efficient upgrade to make. Take watering to the next level with even more automation using this "NO POWER" system.
*Refer to the "VGrow Upgrade Video" on YouTube to see exact modification.
*Fits a 49mm Round Vertical Float Valve as pictured.
