VIVOSUN DWC Hydroponics Grow System with Top Drip Kit 4 Buckets

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.

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

6wks in, growth unbelievable compared to growing in coco perlite mix. Rapid growth, dark green leaves, with lots of bushing out... just an amazing difference.

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.

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.

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.

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

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.

I'll note the title first. I setup the airpump outside my grow tent on a shelf. It's an incredibly large tent so the Included amount of airline was not enough for what I wanted to accomplish, no fault of the kit. Everything is included for success minus nutrients. Absolutely nothing bad to say about the kit. It would have cost me more to purchase everything individually and make it just as nice including the drip ring. Yes the air pump is more then enough to oxygenate the water plus run the included drip ring. I found I needed to turn the flow to the drip ring down that's running the largest 8 bucket kit and included pump. Proof is in the pictures it works for picky vegetables so I can only imagine it will be perfect for cannabis if legal in your country for personal use/growth. I'm going to actually try and grow some genuine wasabi in these kits as the drip ring puts out enough water to mimic a running brook. 5/5 stars it's "expensive" but you get everything you need and it just works. Thank you! 👍

parfait super

Easy to set up and maintain. Everything you need

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.
