Some will revert back to dips after being treated if they are not 100% Tet. If you breed dip to dip you will only get dip seedlings and the same with tets. The best way to check a converted plant to see if it took is measure the pollen, tet pollen is larger than dip. I mail my pollen to someone who does this for me. They can tell me if its dip or Tet and sometimes its both, which means its not a full conversion, but there may be enough Tet pollen to set seed. The following year this partial conversion most likely will revert back to all dip.
LLE is where I have got my best to date patterns and I will continue to use it and its seedlings.
