Paul, this is what I use. It works out well for me in my home. If you need another cart, check out these. Cosco or Sams Club, possibly others such as box stores, sell the unit I have on the far left. I have seen them several places and they are about $80.00 (without the lights)I have found they are so easy to hang lights onto. Just hang the hooks on the wire shelf above. The shelf (comes with 4) is easy to adjust if you need more room for tall plants. They are on castors for easy moving.
The other two units came from Housermanns, they were more expensive, come with two shelves, and the lights come with it. I much prefer the cheap metal ones.
Also pictured is a metal pipe rack, which I built myself, to hang my vandas and other hanging baskets.
All my plants sit on large trays with drain tubes which drain into a bucket which I pump out with a sump pump. You can see the rubbermaid bucket between the two left carts. Under the very bottom trays I use an 'under the bed' tray and I pump it, with a cheap pond pump, into the larger bucket. I'm not as young as I'm sure you are, so I try to make things easy to care for.
