Also included was enough hydroton to fill the bucket completely.

I had to write this review to counter the 'What Trash' review, which seems to be written by a competitor intent on scaring people away from this product. What I can tell you is that I've used four of these buckets for 3 years and never had a single problem with them.

They do not leak, period. Which is nice because you might be growing in your home.

The drip rings do not clog easily. You need to wipe them off with a damp cloth occassionally but not very often. You can easily detach the ring from the t-connector if you need to rinse it out or want to be really thourgh.

The buckets can grow medium size plants. I found that trying to grow large tomatoes outside required the 2 gallon reservoir to be filled every couple of days. However if you want to grow larger plants then you simply upgrade to a larger reservoir. This bucket is a 'module' that can be connected to larger systems that General Hydroponics makes.

So in summary this is a solid purchase but I feel that you are paying a little extra for the modularity of the system, meaning the opportunity to upgrade to a large system. If you are sure that you'll only want stand-alone growing buckets or don't need the square form factor then you can probably get something cheaper.

Gone is the "elite 500" and with good riddance. GenHydro is now including a single diaphram pump that is adjustable. ADJUSTABLE. This is great for the larger plants that have a thicker root system, as the grow chamber can flood sometimes if the drainage isn't optimal. (Avoid transplanting anything bigger than a quart sized pot into this bucket.)
The three part Flora series was included...they are the 8oz bottles, but that should be enough to run a full cycle with the bucket. (Having the entire line of supplements from GenHydro will GREATLY augment your results.)
Also included was enough hydroton to fill the bucket completely. Burying the drip ring in hydroton will minimize overspraying onto lower leaves and keeps the top layer of pellets dry. (And algae free.)
I have successfully grown 5ft tall perennials in this system. It has never leaked, and this particular purchase was my second WaterFarm. The first one is still in GREAT condition, and has been incredibly easy to maintain. The only thing to note is that changing the reservoir can get tricky if you have a large plant growing in the grow chamber. What I've found is the easiest, is to set the whole module on an inverted bucket. (Don't jam your plant into the lights, be careful.) I then pull the blue tube out of the ring, and twist it until it is at a downward angle. The water will pour out of the tube and into a (hopefully) ready bucket. To refill it, just return the blue tube to it's upright position, and pour your nutrient solution in through the top of the grow chamber. If your drip ring isn't buried, then you'll probably notice a little salt buildup. Wiping with a damp cloth or running FloraKleen once a week for a day or two will minimize this.

Absolutely fantastic way to grow indoors or out!!!

So, I absolutely love gardening, but I SUCK at it. Whether it is overwatering or underwatering, I could just never seem to get it right, seriously, the only thing I ever successfully grew from seed to harvest was a lima bean sprout for elementary school. With this the goal is actually to have your grow medium constantly saturated, and the air pump provides aeration, so no more drowned plants! I wanted to wait till I had a great picture to post with this review, but I am so excited about this I had to write the review right away!

I literally just got back from confirming that the WaterFarm I put on our patio has sprouted buttercrunch lettuce from all three of the rockwool cubes that I put in!!!

This item is built extremely well, and I have no doubts it will be growing me some amazing veggies for years to come.

Now a little tip: a lot of gardeners will say not to add any nutrients when starting a seed, but the "Flora series" nutrients that come with this kit (which I also love) actually recommends adding nutrients, just much less than usual, and that is what I did. The lettuce is not leggy at all either, I just made sure 1 layer of clay pebble covered the rockwool, and the heads of lettuce sprouted just about 1/4 inch above the very top layer, and look perfect!

Side note: General Hydroponics is actually the granddaddy of consumer grade hydroponics products, and have been around since the 70's! I didn't know that at first, and I have no trouble at all believing it after using the products, these guys know what they are doing!!!

The reserve only holds about 2 gallons. 2nd month of a tomato plant and the roots have taken atleast half a gallon space. i'm left feeding her atleast once a day. Its a great system. works like it was engineered to do. I still run 2 gallons in mine but the nutes sit all the way up in the hydroten. The extra work maintaining the water has made it very time demanding.
