OK, I've got this fishfood for hatchlings which is powdered stuff. This is something Tom Hayes turned me onto a few years ago and I have had mixed results with it. I've never done any controlled experiments but some plants seem to like it, a few don't (montana tomentosa comes to mind). I use very little of it at once, dipping a toothpick into the powdered stuff. I've also wet it in the past. The biggest problem is that it will grow fungus/mold pretty quickly in a very humid terrarium, but occasional misting will take care of this. Also, runoff into the soil can't be too good.... You might want to experiment with spray fertilizers as its a lot easier to apply the stuff. However, my experiments with Miracid vs. Miracle-gro have had mediocre results. I think the Miracid is better BUT must be used in moderation. The control (sprayed with H20) grew pretty well. The Miracle-Gro plants nearly kicked the bucket after a few applications. I could have used too much / too frequently. Anyway, after my next plant sale (when I hopefully free up some space), I think I am going to do some more experimentation. I would have tested Superthrive as well but I couldn't find my bottle so had to reorder it....
