VIVOSUN Professional Automatic Drip Irrigation Kits, 15W Output, All in One Professional Grow Kit- Includes Pump, Timer and Regulator, 8 Drip Emitters Garden Plant Watering System Indoor Outdoor

Works well, distributes water evenly between each nozzle.

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.

The pump and tubing are quite good. Vivosun supplies a generous amount of good quality tubing.The included timer is difficult to use and configure, and doesn't connect to wifi or anything fancy. I had one incident after programming it: it started at 8am as desired, but didn't turn itself off. At 11am, I came in to find my tent filled with 3" of standing water.Advice: use a wifi plug or regular timer for this water pump and get rid of the vivosun timer.

Edit: after a month, only 2 nozzles dispense water, nearly lost 3 plants because these unexpectedly stopped working. Such a simple propposition, pump water through a few plastic hoses. The issue with these are the injection molded splitters that come off the main tubes. Either don't work, fail after use or when they do work, dispense at vastly different rates from each other. If you need to rely on these, you'll end up with dead plantsOriginal reviw:I have all five other Vivosun products that I am very happy with. This "Professional" automatic irrigation kit is very disappointing. It only has to do one thing and that is pump water to the plants. I assembled carefully following directions and only 5 of the 8 irrigation lines had any flow. I made sure there were no kinks and that I was using pure clean water. Ultimately I had to take 3 of the lines off, one from one splitter and two from the other 4 way splitter (not easy to get off once they are on) and use a 1/16th drill to drill out the hole because it was not patent....defectively manufactured. So, if you use these, verify that each line works before you depend on this system to sustain your precious seedlings. After the non working lines were opened, it worked but each line had a substantially different flow rate, some dripped twice a second, others once every3-4 seconds. I would only recommend this for emergency use if going of vacation with no one to water for you. Even then there is a risk. 2 Stars because ultimately it did pump water, I had no time to return it before leaving on vacation or I would have.

Great product

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.
