This sounds very Cooool.... BD just sent me the instructions for my Phals, thank goodness because I have no clue. By useing this "S&H" it would change the watering procedure all together, wouldn't it? I kinda like "old school" however, I do like the idea of being able to see the roots... they remind me of "spiders" and the roots are part of what attracts me to the plants! It would be cleaner too, I supose. Is it very exspensive? I would only need enough for four pots!
