Agar is used as microbial solid culturing media. The substance is often used in doses ranging between 0.5 to 1.0% (w/v) to solidify plant tissue culture media. Agar is an essential ingredient used for in vitro root development.
I have been using the PCT Supreme Grade Agar for plant tissue culture and orchid seed germination for several months and have found it to be very good in terms of performance, color (essentially colorless), clarity, and gel strength. At about 6.5 g/L it gives me a very good gel for my purposes. The price is very good too.
