Agar
    #26781099 - 06/25/20 03:56 AM (3 years, 7 months ago)

Hey everyone. I am new to mushroom cultivation and have a question about agar. Is there a difference in agar used in a lab (sold by scientific supply companies) and agar sold for use in cooking (on amazon). 500g of agar powder from a scientific supply company is working out at 65 euro but I can get 500g on Amazon for 22 euro. Are they just marketed differently, or is the food additive agar inferior for growing cultures and mycelium compared to the one sold by scientific suppliers?

I use the agar agar vegan gelatine sold on amazon for cooking/desert making. Never tried the lab stuff as you said it's more expensive but might be better I don't know.
The amazon agar has worked well for me and never needed to change.

The lab stuff is pure agarose I believe and is much clearer, has less colour, smell, particles in it, dissolves better. For "garage lab work" the food agar works great, and is much cheaper.
