So I got this flask of gigantifoliums. It was way over due for a de-flask (or preferably re-plate) evidenced by the fact that every seedling only had 2 good leaves left and 2 or 3 dead ones and no live root tips anywhere. They obviously ran out of nutrients long ago!
Anyway, rather than take them out as is, I decided to try to introduce some nutrients back in there before I disturbed them. It was a plastic whiskey bottle so I cut the top off and left them for one week. There was only very mild contamination of the agar. Then I gave them a hit of very week fertilizer with all nutrients. (swished around just enough solution to cover the roots and the base of the plant, let it sit for a few minutes then emptied) A week after that I gave them some IBA rooting hormone. There was little change in leaf colour but a week or so later that I noticed that most seedlings had a tiny new root emerging from their bases.
A successful kick start I think!
They are now in community pots and looking quite ok.
