VIVOSUNFlexFeed Drip Irrigation Kit, 4W Automatic Irrigation System with Pump & 4 Drip Emitters, App-Controllable Professional Plant Watering Drip Kit for VGrow Smart Grow Box

Works great. Good flow

I first tried using only the flex feed watering system and placing the 5 gallon grow bags on them to grow carrots. Unfortunately my carrots never grew after seedlings despite the system keeping the soil moist. So I added the irrigation pumps for the flex feed and the carrots are on schedule for growing. Carrots thrive with consistent watering and they like the coco coir, vermiculite, greensand, worm compost and slow release fertilizer. It got unusually hot in my greenhouse and with the temperatures in the 90s, the reservoir became low and the irrigation pump made a squealing sound warning me so I filled the reservoir and it started pumping the water as usual. The reservoir indicator would have let me know it was low if I looked at it, too. I like the fact each pump doesn’t take much energy to run and they can plug into a separately purchased multi charger unit. Great quality products to use in my root garden I can grow year round in my greenhouse.

Plants are looking their best!!! Very good system!

With vgrow system it only turns on when a serten temp or humidity is reached you can make it run manually with the app as will but ultimately best if you gust water it yourself

I understand the listing makes no reference to the Growhub smart controller. I decided to try it anyways because the growhub has an irrigation controller setting page in it and Vivosun sells no other pumps that they say work with the app or have a USB.I hooked it up using an OTG adapter that adapts USB type C to standard A USB. Powers up fine with a PD USC C type charger. However, when connecting to the Growhub, it will not work. I tried several variants using Vivosuns USB-C Y adapter to add a power source in addition to the Growhub. While I could get it to power up just fine, the Growhub would not recognize it.As an aside note, I also have an AC infinity smart WIFI controller as well. I was unable to get this to work on there as well.In that case, why does the Vivosun Growhub smart controller have an irrigation (or humidifier) setting when they sell no products or adapters that support it? I have even been to the Vivosun website to check just in case it was not sold on Amazon and they had nothing either.I am guessing these options for the Growhub were future plans VIvosun was planning to release but never got to releasing. In other words, vaporware.This just leads to the consumer (myself) being having a bad experience due to an confusing incomplete product ecosystem with gaps in it.The only reason why I bought this as opposed to a higher quality pump in the first place was to use out of the box with a smart controller.Because I can no longer do that, I am returning this, and buying a better quality pump I will just hook up to my AC infinity controller with their wall outlet adapter.

It works flawlessly. When paired with a smart power plug, it becomes a perfect solution for enabling remote internet operation

The new Vgrow upgrade integrates seamlessly right out of the box. Connect one hose to the pump, install, and plug into the USB 2 in your Vgrow. I love that it allows my plants to be watered on a schedule according to the recipe or manually with the Vivosun app. If you own a Vgrow, this is a must have addition!

This does work and works well, the problem is, the VGrow itself has a humidity problem IMO and once you add this, it seems to get a little worse or at least for me it did.I have 2 VGrows and 1 of these, so might do some testing down the road.
