It can be the seed genetics, the hemp grower, climactic factors, or just plain bad luck It can be a combination of all. Genetics play the largest role, as you cannot change what you have in front of you. The grower needs to be attentive, observant and give the plants the correct amount of nitrogen and water. The important part is timing for testing, any tardiness can give a crop a hot reading. Both poor climate and/or animals gnawing on them cause stress to the plant. Stress can change or speed up the CBG, CBD to THC process or slow it down. Climate problems can be somewhat mitigated.
We here at Las Vegas Greens have achieved the lowest THC percent for our strains in the State of Nevada. We grow in our climate controlled greenhouse, we apply our proprietary nutrients and create our own STS spray. In an effort to help growers avoid a hot crop, we strongly advise you to test your crops by an Independent Lab 7-10 days into flower. The test results should come back with a 0% THC reading and a scant CBD reading. If ANY THC shows up on the testing you must keep a watchful eye on your crop, do additional testing and then harvest your crop about 2 weeks early- proactivity is the key. Also, the rule of thumb is that your initial CBD test number can be multiplied by five, which will give you your final CBD percentage. You can take all of the guesswork and anxiety out of your end result.
