Highest point, usually close to the supply from what I recall.will i get air locked if the elevation of my pipes works like this? my res is on the floor same as the trays. if so where would i put the air bleed valve? ive attached this very detailed drawing to illustrate (LOL)

You can put it vertically in the tray near the plants, but a small hole just above water line in reservoir would be advisable or you could put the valve in reservoir in horizontal position.
I did not because I wanted the falling water column in the riser pipe to assist unseating the air valve and the impeller style pump isn't harmed by a little reverse flow. The water in the lines from top of reservoir to height of distribution manifolds will drain out to plants once pump is shut off. Also my installation of air valve is not perfectly horizontal but is tilted down maybe one degree. I found less water burbs during pump turn on in this position. Did I explain well enough to make sense? I am a bit high.okay i think im gona put it at the top in my reservoir. did you put a check valve above your pump? if so why or why not.
cool i think i have enough info i sorta messed up my first try. actually no i failed lol. i was trying to keep everything self contained including the manifold with the little hoses inside the reservoir but i didnt have enough room so i went on a second trip to the hardware store i cleaned them out this time. im going to try again when i have more timeI did not because I wanted the falling water column in the riser pipe to assist unseating the air valve and the impeller style pump isn't harmed by a little reverse flow.
