thanks for breakin it down for me:thumbsup:
i was just reading throught the CAP ebb & gro instructions (pdf) and i was looking through the parts needed and everything is based on 1/2" tubing and connectors. I was going to use the 3/4" tubing and fittings. Anything wrong with that? i figured if i was using bigger buckets (5gal) it wouldnt hurt to use bigger lines and fittings. Anyway i noticed on the parts list i noticed they included 90 degree elbow fittings for the controller bucket feed line that have a hole in it to break the vacuum seal in the tube....
ive been googling for the past 20 minutes and i cannot find the part they have. could anyone supply me with a link to find this particular part? Maybe i dont even need it? could i just punch a hole in the tubing about an inch above the water level and it have the same effect? or would this create too many air bubbles in the water lines?

sorry for the million and a half questions lol im totally new to hydro and i just wanna do it right:rastasmoke:

You can stop googling, as long as you have a small drill bit. When the pump in the nutrients comes on, the pump of course sits at the bottom of the 50 gal barrel. it travels up to the top of the barrel where it exits and goes back down towards the control bucket. At the top of the barrel, rather than kinking the tubing, you need to install an elbow. Install the elbow, and then using the drill, punch a small hole into that elbow at such a place that when the water pump is on and pumping the water to the control barrel, the water will spray out through that hole and the water stay inside the barrel, not in your face or out the top! That's all it is
