Thermite,

I find that fewer plants in larger containers is much less hassle than a bunch in small pots... Regarding a plant going into shock because it was repotted, I wouldn't worry! Mine never slow down... When you do, you may want to add a little vitamin B to your nutrient mix.. I use AN B-52. This generally prevents any slow down when either repotting or severe pruning.

Peace,

Farmer Rich
