so based on Jacks thread about the octa bubblers and such i wanted to share this. i have for a while now been wanting to integrate a system that could allow me to use a nute rez and a h20 rez. i wanted it to feed, feed, then water, then repeat. i figured it would help overall in addition to giving me extra time in between rez fills plus now i know exactly what time they feed over a guesstimate that i got with the titan apollo-2 () that i used to use. now i also know how much time until the next feed and etc. so i started looking online and at HD to see what my options were and wanted to kinda see how cheaply i could do this.
this is also coinciding with a new crop in larger pot sizes. last run was 9 plants in 7 gal and this run will be 3 in 7 gal with a 75/25 coco/hton and the other 6 are in 10 gal with pure
canna coco. with those 6 pots being bigger i knew an upgrade to the 12" halos was gonna be required so that meant more pressure as the halos need extra push as it is. so that meant new pump and basic rework of the plumbing. whats shown here is what i ended up with.
the "start box" is the pump start relay. this one was $55 at my local plumbing/irrigation place, their cheapest one, but u can get an orbit brand online for like $35. next is the controller. i got a hunter xc800 at HD for $98. i unfortunately passed up a hunter pro-c, brand new, off ebay for $35. make sure when u get a controller that it has a "master valve/pump" output, some of the cheaper ones dont. the soleniod valves are orbit and are from HD @ $13 each. i elevated the rez and did the plumbing underneath. a mag-9.5 draws down through the spin clean for the chiller circuit. ap-1oo w/ 8" disc for air. the h20 rez was one of my ro rez's so it has a float in it so i extended the ro discharge to its new postion so now it will always be full. the front outlet with the rad ball valve is so i can manually feed a tea using the pump.
i decided on the flotec 1/2 hp utility pump from HD (). after a little fine tuning of the ball valves its providing sufficient pressure to all 9 ladies.
i set program a for everyday at noon, for 1 min, for station 1 (nute). program b is on the odd days at midnight, for 1 min, station 2 (h20). so now i know that even if the nute rez runs dry, within a max of 48 hours they will atleast get water.
here.....we....go!
