i will wait a few days until everything gets settled in before making initial photos....there are some variations to size but it hopefully will not be a factor if the coffee yields noticable benefit. It would need to be a substantial to justify it's application considering the havok it has the potential to wreck on the media.
my initial hypothesis however is if the roots are able to absorb the coffee without being damaged it will be of great benefit to smaller drosera especially SG ones but not so much to larger ones which can catch their own food. i wish i had enough plants to go around....would like to make a 3rd test with 30-10-10 fert. eh maybe another time if the coffee helps......common sense dictates if the coffee is ineffective then the 30-10-10 would be as well.
