Well the aero cloner, after some dialling in, is exceeding my expectations. I'm literally going to bed seeing nubs and waking up to roots. I'll try getting before and after pics to illustrate this, but what can I say, I think I've actually got more clones than I need.
Dan's opinion of aero cloning=10/10
So far. I'll try a few different strains before I recommend that you go out and buy one, but buy one! I saw an unquestionable increase in rate of rooting when I added a timer set to 15 mins on/1 hour off. Possibly root growth rate could improve with a longer 'off' period. I'll try it and see and post the results.

Edit: I had cuts from the exact same strains in rockwool as in the aero cloner as you may see in previous pics. They barely had nubs or anything, while the dome ones had roots and were ready to pot. Both cut at same time, same mother plant. Moved them into the cloner and roots showing after 3 days.
I'm a 'try both and see' kinda guy :) aero cloner pissed all over the rockwool
