You can establish your laboratory for practically nothing, and then acquire the instruments and materials slowly, over the course of many years. I started dabbling seriously in science at about ten years of age. At age 13 I was able to set up a chemical laboratory.
Every lab needs some sort of table or bench.
These tend to be both shaky and flimsy. If you can, position the table in a corner of the room, so that the table contacts the wall on two sides. This will help stabilize the table against side to side motion. An ideal work surface I have used is a 3 by 6 foot piece of plywood supported on two two-drawer filing cabinets. This gives you a surface and a little bit of storage space as well.
