Thankyou for such a quick and helpful post again, yeah the tubs are all houned together with 32mm hose like in the photo i just added, thats a top view obviously and thats just for the bottom layer, tub 1 & 2 have another tub on them with a rockwool slab in it like in the other photo i just added. Yes i see what you mean about water following the path of least resistance, it will only goto tub1 and when i want i just block the hose on tub1 to get it to flow to tub2, but im going to just add another
pump and hose so the reservoir will have a direct pump going to tub1 and another one going straight to tub2. Any idea how fast i want the pump to be pumping into the tubs to circulate the
nutrient solution? the tubs are 45ltr ones i think and the pump i have at the moment i think is just a 350ltr an hour pump and i have it turned to maximum.
Thankyou so much for your time mate.
I also have a few questions about the drip feed if your up for it lol
