I will be using either grow rock or hydroton. I am really hoping to go the grow rocks way to get away from the clay dust of the hydroton.
Thanks Carolina for the suggestion of octabubblers. Which colour of inserts to you suggest I run to control the flow of the drippers ?
Johnie, thank you so much for your reply. Your ideas are great and sound !
I will be able to cool the nutrie
nt water as we will be using water chillers to cool the rooms and a bonus of water chillers are you can hook up cool coils on a thermostat to keep nutrient reservoirs cooled.
I am so excited with this build. So many great advancements with lights, buckets, everything in the last couple of years.
How many gallon reservoirs would you suggest given there will be 50 buckets to drip into.
Love your idea in letting the drips run 24 hours not just when lights are on.
Any other benefits to running 24 hours of dripping other than to help prevent clogging? Could the dripper pump be one that's not submerged in the reservoir tank but rather on the outside of the tank to help prevent unnecessary heating of reservoirs?
Thanks again so much for your reply and help
make sure all drip lines are of equal length precicely and that all dripper outputs from main line are cut precicely the same spot for each line everywhere. Also, the opposite ends of the line from the tank, do not just cap drip line at the end, wrap it all the way around having all the drip system at that end in rectangle/square shape path of water line.
| = main water line.
Not | with a cap
Do [] so it all wraps around. this will help all drippers to have equal flow.
And run drippers all the time low slow flow, rather than on a cycle, for stability of EC/pH in such a large system is my suggestion, always running during lights on, and on a cycle during the night, so the tank must stayu very cool with a pump running and the pumps must not make water too hot. If you cannot maintain cool water with pumps always running, then scratch this idea. running always drippers also will keep entire system cleaner. you must also have a way to clean and drain the whole sysytem, having a T connectio0n somewhere so instead of reciculating back to tank will shoot water right through to waste.
Also, you may want to have a second tank of water for easy emergency refill of main tank/s working off a float valve, so if you are not there and for some reason the water would of run dry, at least they will have fresh water and not die until you get back.. so a second tank with fresh water set to pump into main tank working off of a float switch inside the main tank if the water level drops below certain point.
Make the hole for the drip line over a plant, and use this drip line to feed the plant next to it. all of them like that for nice equal lines, and if it leaks right there at drip/main line connection will be over the pot and not between the pots for example if you made holes there.
Good Growing!
Nice setup!! I would connect all buckets with hard pvc pipe at the bottom bucket to bucket and run drippers 24/7 so when they drip inside this will create splashing and humidity and no need for air pumps individually inside, it will have this booster effect just from the drip and stability of EC/pH/temps/and clean this way recirculating constantly for such a large system.
