If grown outdoors in proven soils and carefully processed, industrial hemp can be a viable source of CBD. But it is not an optimal source of oil rich in CBD for several reasons. Industrial hemp typically contains much less cannabidiol than highly resinous cannabis, rich in Sera Labs CBD Oil, and large amounts of rare hemp foliage are required to extract a small amount of CBD.
This increases the risk of contaminants since Hemp is a bioaccumulator, which means that the plant collects toxins from the soil. This is an excellent property for phyto-remediation purposes, but it is not very good to make ingestible medicinal oil concentrates.
The highly refined CBD paste derived from industrial hemp foliage is a poor raw material for formulating CBD rich oil products. Typically, imported hemp paste and products with pure Sera Labs CBD Oil powder derived from hemp that proliferate online, include a solvent agent, which dilutes the oil that is heated and inhaled by vape pens users.
