It is important in the laminar flow cabinet to have the box into which the tissue cultures are being planted open for as short a period as possible, to reduce the risk of infections. Larger boxes with larger cells with more plants will take longer and this increases the risk of infection. For the transplanter there is no advantage to have larger trays with more plants, as it is able to transplant out of multiple Nic-In trays at once. For instance we have a transplanter that currently transplants out of 3 Nic-In trays at once, transplanting 21 plants at a time.
