You can mix perlite and vermiculite in a 50-50 ratio (or any other ratio you desire) to get a combination that retains more water than pure perlite, but less water than pure vermiculite. Depending on your gardening needs, you can also look to the various alternatives, such expanded clay, expanded shale, pumice, and peat moss.

Expanded clay (LECA) and other light weight aggregates such as: expanded shale, pumice, slate, perlite, bottom ash etc. have been successfully used in the production of lightweight concretes (LWCs) over the decades [1,2and 3]. Use of those aggregates has property to the sustainable

Loosens clay soil; Improves drainage and aeration ... Expanded perlite is formed when normal pyrite is heated. Heating perlite to a range of 1,560-1,650 °F (850-900 °C) causes the mineral to soften. As it does, the water that's trapped in the volcanic glass vaporizes and tries to escape. This causes the glass to expand to 7-16 times its ...

I should look for bags of clay instead to make brick then, and maybe mix in either Leca or Perlite in the rocket bricks. Well, need to find out if this is an option at all.
