Can't find any info, Id think somebody would have tried.. dusting roots with ga3 (along with Mycorrhizae... ithink worth an experiment.. I'll give this a go with next seedlings I get going.. love some info if there is any out there..

I understand the test itself will require a learning process, in which case I am willing to listen to any sensible...
