After hearing the price of an ez cloner at my local hydro store...400+ Yikes! i decided to buy some of those nice rotary sprinkler heads that dont jam, they cost about 2 bucks a piece but i think they have better coverage than the ez clone ones... anyways long story short i built one of these bad boys and it was a little trouble to get the clones to take root quickly.... after a little rhizotonic, a slight of hydroguard and some pbp grow the clones started to root rather rapidly. Thanks for such an informative thread... and to those of you who were considering making one of these... go for it! they are the best.
