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

I don't get all the negative reviews on this irrigation system. I usually buy from AC Infinity for these types of purchases, but they only seem to offer single water pumps rather than a all-in-one system like this product from Vivosun...and it rocks. Not sure why there are complaints about leakage and/or grow tent flooding. My experience has been just the opposite. I recommend barely, if any, adjustments on the regulators. This might be the issue for a lot of people. Opening them up too much will certainly cause a leak. Another culprit for flooding might be not following the directions to use the included tool to poke a hole in the hose at the top of the bucket so water isn't syphoned out into the grow area. The tubing I received was packaged perfectly- wound in a nice coil with ZERO kinks in it from the manufacturer. Maybe this was a quality issue that has been resolved by Vivosun. Either way, no complaints here. I can't speak on the included timer. I chose a third party option that allows me a bit more control than the Vivosun unit. The water pump itself is a durable 15 watt pump. I'm experimenting currently, but I have the pump cycling on for 2 minutes every hour. The pump cycles through without fail. Installation was a breeze and the instructions were easy to understand. Since this is a standalone system, you don't have to connect it to an integrated controller or anything like you would with a system that syncs an inline fan, lighting, etc. to one another. So no connection quality issues - just set up the included timer. Also, the $40 price point is fantastic considering you're purchasing a full irrigation system right out of the box. I didn't have to buy any additional components to get up and running. I went out of my way to leave a worthwhile review of this product due to it's ridiculous sub-4 star rating. I HIGHLY recommend this irrigation system. Some of the negative reviews here have to be chalked up to user-error or past supplier quality issues. Vivosun has earned my future business.

Once again VIVOSUN has made a great product! My entire growing setup is all VIVOSUN and I don’t have 1 complaint. They all work extremely well together, easy setup, and great quality. I’ve read many reviews on this irrigation system. I’m not sure why people are giving bad reviews. Follow the instructions and keep your tubing tight (not a lot of slack) and even lengths. I turned the pump speed to about 50% 2 stakes per 5gal pot. It takes about 12min depending on your medium to get adequate runoff. People complain about tent flooding. Well you need to expect runoff so I purchased some elevated trip trays and the system works flawlessly! I recommend flushing your pots about every couple weeks to prevent nutrient lock but other than that it saves tons of time and keeps my plants healthy!

So far things are working as planned. However my first grow wasn’t successful. Nutrient lock out

This thing is excellent - make sure to keep your reservoir fresh with a fountain or something that agitates the water- I ordered a very cheap package of different add-on strippers instead of the spikes. So the watering line actually sits above the soil and I can see it drip in. I like it better like that than the spikes

Everything in this kit functions - and it's still not worth it. The pump is very weak - with a 1 meter limit on raising the water. The emitters deliver too much water for a lot of plants and if you have a mix of plants you need more control. The app that controls the wifi plug is really just bad. It loses state and the schedule doesn't always work - which is rather the point of all of this. So in the end, after a few days all I'm using from it is the tubing, the Ts and the anti-siphon. Quite disappointing. Can't really return it but I can urge others not to bother with it.

Works great

Another reviewer posted that the hoses are rather kinked in the package. That is true. However, I did some flow tests, and despite the kinks, they all had approximately the same flow. Not enough difference for me to even measure. I have several dislikes besides the kinks. 1) The fitting in the included diagram that connects directly to the pump did not work for me. There is 2 of those fittings in the kit. I could not connect the main hose to either fitting. It just wouldnt go on. There was a 3rd fitting that kind of resembles the first two (though not shown in the parts list, and not shown on the diagram) that works just fine so I used it instead. I was able to get the tube onto that. Thanks for the unnecessary frustration as I dont have enough during the day. 2) It leaks. The parts that leak are the blue pieces shown in the diagram. I have made sure everything is tight as can be and it still leaks. It doesnt leak a lot (about a table spoon in 9 minutes), but they shouldnt leak at all. Other than those 2 irritations, the timer was easy to program and works great. The pump puts out more than enough fluid. At full setting on the pump(it is adjustable), EACH of the 8 lines put out just a tad over 1/2 cup (118ml) in just 9 minutes. So, all 8 combined put out just over 4 cups (appx 1 liter) in 9 minutes.

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.

Ich nutze das Bewässerungssystem von VIVOSUN in meiner Indoor-Growbox mit Coco. Die Pumpe ist leise, aber stark genug, um auch mehrere Töpfe zuverlässig zu versorgen. Besonders gut gefällt mir der mitgelieferte digitale Timer – er bietet viele Einstellmöglichkeiten und läuft sehr exakt. Die Schläuche lassen sich mit etwas Geduld gut verlegen. Bei mir war alles vollständig im Karton, inklusive der Tropfer und Verteiler. Wichtig: Einmal sauber aufbauen und richtig eindrücken, dann ist das Ganze auch dicht und wartungsarm. Was mir aufgefallen ist: • Die Tropfer lassen sich gut dosieren (von Tröpfeln bis kräftig) • Der Timer ist nicht wie bei Billigsets – sondern zuverlässig und präzise • Die Pumpe ist leise, auch bei Dauerbetrieb kaum hörbar • Ideal für 4–8 Pflanzen, je nach Setup Einziger Hinweis: Die Schläuche können anfangs etwas widerspenstig sein – ich hab sie kurz in warmes Wasser gelegt, dann ließen sie sich deutlich besser verarbeiten. Fazit: Für alle, die ein zuverlässiges, leises System mit gutem Timer suchen: klare Empfehlung. Ich würde es jederzeit wieder kaufen – Setup ist einfach, Leistung passt.

Très décevant! La longueur de tube entre la pompe et le répartiteur est beaucoup trop courte. De plus, la puissance trop faible voir l'absence de pompage sont insuffisant pour fournir un débit constant.
