hey amigo, thanks for stopping by!!!
I have a 1500 liter water tank outside the room. I cut a hole in the topside to make mixing and stirring easier. I have a homemade paddle that I use to get the water stirring before I add my nutrients. Once I paddle like crazy and get the water spinning I slowly add my nutrients to the R.O water that is now at 10ppms. I use silica and cal mag at around a 3 to 1 ratio just to "treat" my R.o water. I use General Hydroponics flora series expert chart nutrients and usually half strength. I go by ppm's not so much the instructions.
when I am adding nutrients to my 250 galons I add them one by one in order stirring each time between nutrients.
as you may or may not know you can NOT over water a plant. It is lack of oxygen what is bad not overwatering so I make sure that I always have as much disolved oxygen as possible. 1.I have constant air being pumped through air stones. 2. make sure each time you have to move the water from the rez to the controller or visa versa you cut the hose lenth so that the water must splash to add more O.
I have a chiller running directly to my rez to keep the water cool. cooler water equals more disolved O and warmer water more root growth. I prefer cooler. right now my rez is at 68F because of the lenght of hose that is exposed in the room. they hold some residual heat and will slightly warm the water a couple of degrees when it gets to the roots.
I am on 12/12 day 3 so I am currently running like 4 cycles per 12 hour day. the first cycle as lights come on, than every couple of hours and last feeding finishes 45 min before lights off.
Rh now is around 50%
I am adding 4 liters per hour to the room of water.
Inside the room on the other side of the wall is the controller bucket. I will take pictures tomorrow, but it has float sensors and a ebb and gro brain hooked up to a large plastic bin that has 8 3/4 in hoses hooked up to it. each line feeds around 30-35 10litre buckets.
