Dina 19-08-2019 Would love to know at what temp the frozen material must be kept at
Alchimia Grow Shop 20-08-2019 Hi Dina, It depends on the starting material but if it's Fresh Frozen then it definitely needs to be kept as cold as possible, although there's no need for industrial equipment. I keep mine in a regular chest freezer at around -20ºC. Hope that helps, all the best!
