This system is a great choice for the gardener who is space conscious. It's practical size and heavy duty design will last for years. The ebb and flow plastic tray itself is 5mm thick, 2ftx 3ftin size, with a height of 8 inches. I personally designed, constructed and tested this ebb and flow system andis used as a medium for growing herbal medicinal plants. Guaranteed to work with dramatic results. Plants grew about 8 inches in 2 weeks, leaves are greener, healthier and you will have a "sea of green" in less time. Can actually handleminimum of8 plants up to 18 plants in a 5-1/2" square pots. And the kit comes with the following items:

1. 2' x 3' 25 gallons capacity ebb and flow tray

2. A 130 gal/hr submersible pump with just the right amount of water pressureto fill up the tray, with water flow controller on the side

3. Fill-drain and overflow fittings

4. 1/2" size blue hoses

5. 2' x 3' 25 gallons capacity reservoir

Just provide the stand as shown in the photos, either made of PVC or wood. Make sure you place it on a flat surface like a table or even a well supported PVC stand. Use the reservoir that comes with it or as another ebb and flow tray, it's up to you. Or if you decided to put 5 gallon black buckets with interconnected hoses or a tall 30 gallon capacity black rectangularreservoir to prevent algaes. Warranties will be2 months on tray and15 days on pump, void if used in other instances than the intended purpose. Better get this one and i know you wont regret it. Sold two sets already and will keep on going.
