    Well, small pipe pipe work and specifically the connectors are way cheaper than there bigger versions.

    ie, 25mm tank connector is £4~ and a 50mm is £15/20~

    I use 25mm outlets in my veg system, but it’s got a really low flow pump for circulation and before the plants get too big they get thrown in the flower system with twin 50mm outlets.
    I would not like to try finish in the veg system without trimming roots etc, you might get away with it a few times but eventually it will block and you will end up with water everywhere.

    I’ve got 56mm pipework on mine, you think just that will get blocked with veg then flower ?

    I’d imagine you should be fine with that. But I’d never like to say it would never happen because it still could. Im thinking about building overflow pipe work in to the new system to avoid this problem.

    if you balance your return pipes you will not get any roots in the pipes.
    im using 40mm returns, cheap and plentiful, and have never had a root blockage, never...because my system is designed properly.
    its also had 25+ ounce plants in it, with no issues

    ahh sorry for not getting back sooner, balancing them only applies if you have a gravity return, which your system doesn't.
    yours is using a pump to putt the nutrient thru the buckets and is more of a proper recirculating system.
    when I said balancing the returns , I meant that if you keep the returns in the exact centres on both sides, the pull from the gravity returns will be equalised from both sides meaning the roots don't get drawn to or thru a pipe, they just kinda float.
    because yours is a single pipe in, single pipe out system, and nutes are pulled thru the system, your best bet is to rotate the pots a 1/4 turn every day or 2, to prevent roots migrating down the out pipe. placing an airstone near the out pipe also helps float them to avoid root blockage issues.

    Ah rite I get you matey yeah, the flow on my pump is 1050 an hour but I think it will be less than that after it is ran up and through the chiller and back. So the flow isn’t stupidly quick in which I hope will help in some ways.

    I’ll deffo take on board what you said about the air stones though.

    If it doesn’t work I’ll just do another design lol

    What are your thoughts on how many pots should go in what area? I could stretch to a 1.5m2 tent.

    Also your thoughts on pot size would be nice too.
    Evening braking bad my self I've run both a 4 pot and 2 pot with header tank rdwc homemade setup in my 1.2m x1.2m tent and done really well if you want to grow trees go for it they will love you for it Click image for larger version.
