Nova OG makes a very good concentrate. The fact that Nova OG has about 20% THC and 19% CBD means that you can make a very potent concentrate with a very nice flavor profile out of it quite easily.
You can use a method such as butane blasting to create concentrates. It is important to know, however, that making butane hash oil is pretty dangerous. Butane is a highly flammable gas and has been the cause of many home fires and explosions from blasting it into the wax. Unless you are very well educated on the process and take all the necessary precautions, it is not recommended that you do it.
You can make any strain into edibles, and a strain like Nova OG would make some really great medicinal edibles. You must first decarboxylate your weed, and then mix it with a fat or oil. If you don’t do both of these steps, you may as well chuck your weed in the bin, as the edibles won’t work.
