VIVOSUN DWC Hydroponics Grow System with Top Drip Kit 4 Buckets | 5-Gallon Deep Water Culture, Recirculating Drip Garden System with Multi-Purpose Air Hose, Air Pump, and Air Stone

Very easy to set-up, and very high quality materials. Vivosun booklet included has valuable grow information. Grow bucket has an external water level tube which also serves as the drain. Since the tube is at floor level, you need to raise the bucket to periodically drain by rotating the tube to floor level. I installed a 1/4 inch by 16 inches long stainless tube and a small water pump (both Amazon) into the lid via a 3/8 hole (using the extra rubber sealing ring Vivosun included) With this setup I can test e.c. and p.h. levels as well as do a periodic drain. Vivosun should incorporate this handy feature.

Well I am in love... This is probably one of the best units.

Forget raising your suspiciously-fast-growing plant in soil or coco. It craves a constant stream of water, nutrients, and oxygen. A DWC system is exactly what your plant wants, and you'll find yourself growing a jungle if you let it get it out of hand. The engineering is well thought and simple: the air pump pushes air into the tubes, which in turn moves the water up and oxygenates it. The assembly was not hard, but took a few minutes of focus and precision to get the tubes hooked up right. Put this bucket system in a Vivosun grow tent, with a big grow light and some good genetics, and you'll be growing the most potent medicine in the neighborhood.

The product is of decent construction, however I have a few gripes. One of biggest gripes with it are the high level of noise coming from the top drip constantly making gargling sounds which I can hear throughout my house. The air stones are not the best, one of mine didn’t work at all. I confirmed air was coming through the hose and replaced it with one of vivosun’s stones that I bought separately and found that air still isn’t coming through. It seems the pump simply isn’t putting out enough pressure to push air through the air stones since the same pump is pushing air through the top water drips which is a path of least resistance for all of the air. They should have designed the pump to separate the air for the top drips and the air stones Lastly the clay stones that come with it make a ton of dust/mud when wet. Even after rinsing them all off out of the bags they came in, they break each other down too easily IMO. I get that they should be semi porous to hold water, but still. Edit after using for a few months: One flaw of using this air powered siphoning system for recirculation is that the water will spray against plant stems which I’ve found to cause rot and damage due to the liquid plant foods present in the water. I would rebuild this system to use a water pump instead that circulates water in a steady stream rather than using air siphoning causing the water to spurt out to avoid this. Another edit: I’ve been using these now for over a year and I’ve been able to make them work better. One tip would be to bury the rings in the stones. This not only protects the stems of the plants from being damaged by being sprayed with the liquid fertilizers, but also prevents algae and reduced the noise of the system. Since doing this my plants are much happier and thriving.

Haven't used it yet but everything looks good there a good deal for the money

This is a good system with flaws. First and foremost, the air is interconnected, but the buckets do not circulate with each other. Great if you end up having a problem with one of the plants. Because it's one air unit, all of them need to be running, which can be challenging if you don't have four plants going at once or if they are not on the same grow cycle. The biggest flaw with this is the top watering ring. I've seen newbies leave this on 24/7 and wonder why their plants are dying. Top watering is so unnecessary for this setup. It's nice that it has an on/off switch though. In the early stages, I will top water for 30 seconds to 1 minute max to get penetration, but that could be accomplished by filling through the pebbles anyway. Overall, it's not a bad setup, but if you're brand new to DWC, you will struggle.

It's Great! Super easy to set up. I had it up and running with nutrients and plants in a few hours. Works well with some lighting and how things are turning out it stays pretty versatile

This is a great kit for the money. Installation was the only downside, getting the tubing through the gromets is super painful but other then that it's an easy process. Note that unlike the picture the system does not stream a continuous stream of water out of the ring, it comes in spurts and sputters. It's actually quite loud, and not in a "zen" garden type way but annoying and inconsistent. I get that a fountain pump per bucket would be costly and maintenance heavy but the air pump is loud and the sputtering is loud, so if you plan on putting it somewhere by a living space keep that in mind. Plants love it, put 4 cucumbers in there and got 100's of cucumbers over the course of a few months, and they are still going 4 months later.

Die Qualität wirkt robust, lediglich die Pumpe ist mir etwas zu laut - wie es sich in der pflanzenzucht macht muss sich noch zeigen

All parts were included and the assembly instructions were carefully thought out. Take your time to assemble as instructed and enjoy the results. A well engineered product and worked exactly as anticipated.

Took 10-15 mins to set up, with just a pair of scissors as the only tool. Instructions were easy to follow and results are great so far! One cherry tomato and one Fresno chili plant.

Do what is suppose to do.

Nicht falsch verstehen der Topf ist in Ordnung, aber bei einem 3-stelligen Preis hätte zwingen auch ein paar Hydroanzuchttöpfe mit Inhalt dazu gehört. So ist es ein teures NICHT direkt nutzbares Set. Meins geht definitiv wieder zurück, für so eine Mogelpackung schmeiß ich kein Geld aus dem Fenster.
