Some options for heavy pot fillers are broken ceramic, broken pieces of crystal, brick, large rocks, or wood logs. Heavy materials work when we need to support a large tree in a lightweight container or do permanent installations.
Milk jugs and juice bottles with he lids. Most planters get filled with plants that require less than 5'' for rooting. Just put clean capped milk jugs or plastic juice jugs in as tightly packed as possible. You can add a layer of landscape fabric then top with soil.

I put a broken up paver or two in the bottom of mine. It keeps the pots from tipping over and allows me to use less soil. You don't need a false bottom, just a bunch of Styrofoam or peanuts with landscape fabric over the top so the roots don't get down. It's not perfect but it will do.
However, because landfills are overfilled with non-biodegradable products, many Styrofoam packing products are now made to dissolve in time. It is not recommended to use Styrofoam peanuts for potted plants now, because they may break down in water and soil, leaving you with sunken-in containers.

Instead of throwing it in the trash, an easy way to repurpose spare cardboard is to line them on the bottom of your raised garden beds. One frequently asked question is whether you can put cardboard in your raised beds. The answer is yes.
Raised beds that are small and shallow (under 12 inches deep) are typically only filled with soil. Adding other organic materials to shallow beds usually isn't a good idea. Sticks, twigs, and other materials further reduce the limited soil space and can interfere with plant root growth and water drainage.
Using Pot Fillers
Besides soil, consider using sand, small aquarium pebbles, marbles, or even glass beads. The idea is to add enough volume or weight to your planter to stabilize the arrangement.
You Can Use a Layer of Cardboard at the Bottom of Raised Beds to Prevent Weeds. If your budget doesn't allow for weed barrier cloth, you can add several layers of cardboard to the bottom of your raised bed before filling it with soil. The cardboard will decompose in about 4 to 6 months.

Plastic sheeting is the best material for lining a planter with. Pond liners work well for lining the bottom of planters as they are robust and can easily be shaped into the perfect size to fit the dimensions of your planter.

Pea Gravel: Small, smooth, and round, pea gravel is both aesthetically pleasing and effective in allowing water to pass through quickly. River Rock: Larger and more decorative, river rock can be the best choice for a significant drainage project.
One of the best things to put at the bottom of a planter for drainage is broken pieces of pot.

Adding a layer of broken pieces of pot like this will prevent compost loss out of the drainage holes.
