The image shows a plant ready for your NFT system. If your plants are not at this stage DO NOT transplant. It is always better to delay transplanting until correct root stage is reached in order to achieve best results in the end.

The reason for this is that if white roots aren't abundant on the outside of the propagation block at transplanting to NFT the block will absorb a large volume of solution. The roots inside the block will be saturated but with no access to oxygen. As a result they will die-back and successful introduction to NFT will not be possible.
