Dr. Atomic Blueberry Jam is the second designer seed strain that I have grown.
I grew out 4 different phenotypes and all came out female. They all looked the same until flower stage. Very short and stocky, very puffy large buds. After drying, a 1/2 ounce looks like an ounce, the patients really like that. Each of the phenotypes were all very different from each other when it comes to taste and appearance of the finished buds.
I seem to have gotten lucky with this one. One of the phenotypes I grew was the right one, a keeper. It is more potent, has great smell and taste of blueberry jam, the aroma is very strong, and is capable of producing large yields. The flower time on the phenotype I kept is about 9 weeks. I am still growing it today, some of the best buds I have had.
On the bad side, the strain is very finicky. I have the best luck growing it under 400W HPS. It can be very difficult to harvest at just the right time to keep the aroma and taste just right. There is a large variety of phenotypes that are lower in quality in regards to potency and taste. The other phenotypes that I did not keep, required a much longer flowering time, at least 10 weeks. This strain can be difficult to obtain the correct phenotype and can be very difficult to grow under 1000W lights.
This strain is decent for making concentrated oil, however, it is a little heavy on the amount of chlorophyll. It is a great plant for topping, it stays short and fills in like a scrog, without actually setting it up for a scrog grow. This plant is equally great not topping it too.
