The chemical composition includes specialized terpenes and cannabinoids, mainly tetrahydrocannabinol (THC), and cannabidiol (CBD).
Imbibition of water through the membrane of the seed shell is the first step in the germination process for cannabis. Dry cannabis seeds are floating, a convenient way to verify a successful imbibition is to put them in water until they sink, which takes about six hours when submerged in an infuser, and about 12 hours when they are floating on ...

[2] The plant produces large amounts of tetrahydrocannabinol (THC) [ 3 ] [ better source needed ] and tetrahydrocannabivarin (THCV), with total cannabinoid levels being as high as 53.7% [ scientific citation needed ] .
Appearance. Advanced oxidation processes (AOPs), in a broad sense, are a set of chemical treatment procedures designed to remove organic (and sometimes inorganic) materials in water and wastewater by oxidation through reactions with hydroxyl radicals (·OH). [ 1 ] In real-world applications of wastewater treatment, however, this term usually ...
The spores of rust fungi may be dispersed by wind, water or insect vectors. [13] When a spore encounters a susceptible plant, it can germinate and infect plant tissues. A rust spores typically germinates on a plant surface, growing a short hypha called a germ tube. This germ tube may locate a stoma by a touch responsive process known as ...
Coagulation-flocculation process in a water treatment system. In water treatment, coagulation and flocculation involve the addition of compounds that promote the clumping of fine floc into larger floc so that they can be more easily separated from the water. Coagulation is a chemical process that involves neutralization of charge whereas ...
Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. The resulting soft water requires less soap for the same cleaning effort, as soap is not wasted bonding with calcium ions. Soft water also extends the lifetime of plumbing by reducing or eliminating scale build-up in pipes and fittings.
