sorry to jack your thread dispostiton, but i must share this......rain drip makes 360 sprayers, they are pure garbage, they have the red caps that break easily, but 2 of 5 fail anyways, so i like to space my sites 9 inches apart, for a standard spray head this is too far unless you make it individually for each site a spray head, what i did was get a 1/4in barbed Tee, put it were i would have a spray head, directly between 2 plant sites, put about a 1inch peice of 1/4 poly tubing and put a sprayhead on each side missing the cap, so in both directions instead of a fine mist, i got a strong jet and i had unbelievable results, i may have achieved a faster vegg rate and hardcore root growth, the jets violently splash against the net pots, giving the aeroflo effect...i highly recommend this if you dont have enough sprayers and your plant sites are far apart, also the raindrip heads are dirt cheap compared to ez cloners for $1ea, i tried to save with BGhydro's for .60ea and wasted money
