    Re: Utter noob looking for buying advice

    I originally was going to use 4 x 5G tubs. Cheap & the net lids are cool. My reasoning behind bins is:

    It allows me to have approx. 22G of water in the system for stability of pH & nutes. 4 x 5G + a 5G res would be less – maybe 15G before root growth? My past life fish tank experience taught me that a big tank is far more stable than a small one.

    It allows me to cluster the plants around the core light area better than 4 x 5G which would have to be staggered in a 2 x 4 tent leaving 2 out of 4 out of the prime light area. Doubling the light would work as well but that is not in the budget this time. And of course, one plant alone or 2 plants would be best for light but we all want more. Right?

    This plan drops the plant base by 4 inches, so more for growth.

    It will require 3 ½” pots (system level mandated) so I will have to fab support as required. I will also use mylar-covered acrylic sheets on top of the modded tote top surface for extra support.

    Much simpler plumbing hookup. 3 totes with flat sides are much easier to plumb to. This is an upstairs bedroom & leaks would be a disaster. The idea of barbed connectors & grommets on a cylinder gives me hives. I am sure Home Despot can supply whatever I need to securely feed PVC lines to straight-sided hard plastic totes. ½ or ¾ lines with 2” return. And thinking it through, I might put a float shutoff for the pump on one of the grow totes to prevent overflow if the filter clogs. But it is not like I won’t be inspecting all of the time anyway . . .

    Thanks guys.

    The final layout (for now)

    Just gunna throw this idea out there. Put a couple shut off (ball valves) on both the return and feed.
    Also use a union on the pvc incase you need to remove one of the totes or reservoir.

    I also see a lot of people use 1 1/2" pvc and use big grommets and silicone.

    Or these work well too

    You were reading my mind.

    Exactly what I want to avoid.

    Thanks.

    If you can't find what you need, just ask for "bulkhead connectors" - they should show you something threaded, with gaskets, that makes a sandwich (lol) with your tote's wall as the inner layer.

    Very useful things, unions. For anyone that doesn't know what they are... picture your plumbing system. Even if it's something like threaded galvanized water line, if you want to remove a section of pipe (etc.), you can't just start twisting that pipe; trying to unscrew one end just acts to tighten the other. That big center section (on metal unions, it's shaped for a wrench to hold it) gets turned and then you have separated your pipes. We used to sell them at the hardware store and people would wonder why they needed such a thing. I guess it's like wall sleeves, lol, if you need one, you'll know (too late )....
