The really useful boxes are great like, but it would be easier just butying the right one eh?
I bought some 60 litre ones from Ikea, but the edges were too sloped, and they leaked at the bottom of the connector. I will try using bigger fittings and extra thick rubber seals.
The bloke who own Alien is a bit of an odd ball, who seems to decide the price of stuff depending on his mood tho.
If you want bigger plants, veg them longer.
the benefit is that the return tubes will simply screw in without the need to drill new boxes.
the really useful boxes are much shallower, and you would have more chance of the roots blocking the flow of water to the return pump
oh yeah, and for the same pressure at the source, water will travel through smaller diamater pipes faster, altho bends and other resistance comes into play. Also, the pumps we use dont offer continual pressure, they are always working against the pipe size.
Ive never noticed much difference in the outlet pressure between 34,22 and 15 if im honest, cos when the pipe is full, its full if you get me.
