Eighteen hours just isn't A great deal time! One method to ensure the micro organism can fulfill this demanding deadline is to stack agar plates only 4 plates superior. An incubator full of tall stacks of agar plates can take for a longer period to heat up than an incubator with small stacks, as well as the plates in the middle of the stacks will even take for a longer period to heat up.
