i'm wondering how the suckit bucket is working out for you.

i have a couple of questions:

1. i want to keep things simple and just mix rockwool croutons with hydroton. have you tried just mixing the stuff rather than layering it? about what would you say your ratio is of rockwool to lavarock?

2. it seems that the trick would be to alter the "drippiness" of the medium so that upper bucket fills at about the same time that the level in the lower bucket rises to the point of actuating the autosiphon. this seems tricky. the rate of drainage from the top bucket to the bottom bucket could change as roots grow and fill the holes. is this where the layering comes in? any trick to getting the timing right everytime (fool-proof)?

thanks in advance
