I've already completed a grow with a 3 pot system I made and it worked perfectly but I've now almost finished building my room in the loft
So I'm upgrading to a 6 pot system with a external res outside the room
Here is the basic layout of the system
They are 42 ltr really usefull boxes with a 78 ltr res
The pipework at the bottom is 40mm floplast pushfit connectors with washers inside and outside the pot
There are tank connectors on either side of the pots so there will be 2 returns or maybe 1 on the outside of each row of pots and 1 in the centre connecting each row of pots
I've also got floplast 22mm connectors and pipe (solvent weld)
For the spray bars running through the top of the pots
There are a few things I'm not sure on though
The size of pump needed I've got a hailea 8860 8000lph pump laying about
(Think it could be a bit overkill) which has got a 19mm outlet
so how would I connect that to the 22mm spraybars
Or would I be better running 2 smaller pumps to feed each row of pots
I'll get better pics when I go up later to finish the pipework off
