I always love runnin the waterfarms, all in all it is a killer little system with a few tweaks here and there from experience.
This is my old mother setup that has been just sittin in the corner for as bit doin nothing.
Runnin feca rocks (hydroton) instead of coco because i can stand fightint he fungus gnats that ultimately invade because the media just stays to wet all the time. Quick flips it is not as big a deal but if your holdin plants in the farms to long the hnats come in strong.
I put a 185gph inline pump on the backside of the bucket rows. This lets me run the pump regularly and circulate the water from bucket row to bucket row, this elliminates the customery one ph bitch bucket and they all stay the same on the nute level as well as ph levels. The pump also helps with res changes so you can empty the system real quick when needed. I will do a full res change every week this round to get the full effect.
Side lighting will be 2-4 400w
hortilux base up base down daylight blues, hanging verticle on bare bulbs. I am goin to try and build a rig using a oscillating fan stand and put a mogul base on it so that the light is actually sittin on a pedestal coming up from the bottom with full hieght adjustment. That way i can put a 400w right in the middle of 4 plants that are already sitting upder a 1k hood. I have been wrestlen with a way to mount these lights under a 1k and I think this will work.
House and Garden baby!! Roots Exelurater will grow roots on a rock so get ready...They are the dutch gurus for sure, I even put them above Canna or Hesi.
