Diatomaceous Earth also known as diatomite or kieselgur, is a naturally occurring, sedimentary rock that can be ground into a fine white a powder with the abrasive feel of pumice. Diatomaceous earth is formed from the remains of diatoms, a fossilized algae that have been left in sea floor deposits. Diatomaceous earth can be used as an insecticide because the fine white powder will absorb lipids from the waxy exoskeleton of an insect, causing it to dehydrate. Arthropods will die as a result of the water pressure deficiency. It can also be used against gastropods and is used by gardeners to deter or kill slugs.
Perlite is a naturally occurring amorphous volcanic glass that is usually formed by the hydration of obsidian. For horticultural uses, perlite can be used as a soil amendment or as a standalone growing medium for hydroponic systems or for cloning. If used as a soil amendment it helps prevent water loss and soil compaction. It can also be used as a good alternative to diatomaceous earth.
Sinsemilla refers to female marijuana plants or buds that are grown to be seedless. This is accomplished by eliminating male marijuana plants from the area to prevent the pollination process. The result is a female marijuana plant with larger buds, no seeds, and higher resin content.
