Some of the rarer CBD oils come from the same hemp plants but grown in more tropical conditions. Some environments have highly mineralized water while some farms don't. Many of the hemp fields that were corn or whet fields are now growing hemp. The profits per acre of hemp are up to 20+ times the reward of wheat or corn but many of these fields are depleted in their soil. If a farmer can get twenty times more per ton of hemp stalks and the lower price per ton for grain, many farmers are ditching their grain business.
Some industrial hemp fields are very dense while others are more spread out. It is easier to grow the more common strains and there is less risk of any growing problems. The rarer strains are already so low yielding and if there is a drought this can give a negative profit to a farmer after their growing expenses.
Note: the hemp that is harvested closer to October when it gets cooler is the type that I would want a lab analysis on. I am hearing stories that the big pioneer companies buy the summer harvest and the 2nd harvest when the hemp may or may not be matured. I personally would want to know if they are cutting down the hemp plants that are not even 50% mature.
The percentages of pinene and myrcene for example, in the summer harvest may have larger percentage rather than a trace amount compared to the summer harvest. I avoid fall harvests. I know that the fall harvest is cheaper to wholesalers than the summer harvest that has higher percentages of monoterpenes and sesquiterpenes which go into the CBD oil. If sending a sample to the Colorado lab, different batches have different results.
NOTE: JUST BECAUSE A LAB TEST ON A BRAND ON THAT TEST SHOWED HIGH TERPENES, ETC., THAT DOESN'T MEAN THE CBD ON THE NEXT FALL HARVEST HAS THAT. MANY PEOPLE SEE A LAB REPORT AND TRUST THAT BRAND BUT NEXT YEAR PEOPLE ARE STILL SEEING THE LAB REPORT FOR THAT CBD OIL THAT IS NOT THE SAME.
If there was a drought that summer, then I would expect much less constituents in that CBD that harvest.
So, if the vegetative cycle is 140 days and they know there is a drought coming, they might cut the industrial hemp at 130 days where if they just waited 10 more days the hemp plants would be mature enough to cut down. It would be nice if they cut the price since the CBD oil might not have the same constituents that people think are in the bottle.
The quality of the really rare industrial hemp is grown from different types of hemp seeds. Some seeds are very large and some seeds are smaller. The rarer seeds will not be as hybridized and will naturally deliver more oil contents that will be later extracted.
In the rare circumstances where the hemp plant gets to grown within its full growth cycle and there is perfect water conditions (with structured water), and there are more sunny days, the terpene profile should be closer to 200 than the more common CBD oils that are sold at a reduced price. Farmers that have an outstanding lab test can demand the highest price for their hemp by the ton while the buyer's that know the lab test showed a much lower terpene count will not be willing to pay as much.
So, when people see a price of one brand that is much cheaper, many people think they are getting a better value but when doing more research it is easy to know that the oil is no where near the quality of the expensive oils that are full spectrum with the highest constituent count in their CBD oil.
I do the testing for people whenever there is a new batch from different harvests. What is my favorite this harvest might be different next time. When all the industrial hemp is harvested at the end of the summer, I get them tested and see which one's are really worth using and which aren't.
I will pick out the CBD product based on your answers.
