Greenhouse needed? Is rainwater an issue?

    I suppose this could be a question for any aquaponics system but I'm wondering when a greenhouse becomes necessary. I live in Northeast Florida and we get great sun as well as rain. If I were to have one of Murray's 3 tote toteponics systems for example would it be detrimental to have it openly exposed to rainfall? Is there a rule of thumb on how large a system needs to be before it needs to be covered in a greenhouse? Thanks.

    I live in Northeast Florida where sun isn't an issue and we receive a healthy amount of rainfall. How does rainfall affect aquaponics systems? Is it detrimental to expose an aquaponics system to rainfall? What is/are the rules around this subject?

    Depends (of course )

    Large rain events can cause large Ph swings which may be an issue for you .

    If you have 10 square metres of exposed grow bed and fish tank and get 3 inches of rain overnight your fish tank / sump level will rise quite a bit.

    Hearting lettuce in my experience rots

    I have two systems , one under cover , one isnt . Im guessing this winter (our wet season ) the uncovered system may overflow the sump a few times which will lose valuable nutrient base , as my fish barely feed during the cold weather , a cover or part there of , even temporary is something i should look at .

    I haven't been able to cover my system - though plans are in the works for some time down the track.

    I've never really had a real issue. As long as you cater for your system to be "overfilled" with some sort of overflow in the sumps etc.

    Aside from a little diluting of nutrients it's not too much problem.
    Though as Terra points out above - i have seen a little rotting where it gets wet and doesn't dry out. Nothing major, but it does happen.
    Of course, as with all gardening - the plants can be damaged in a heavy downpour - that's probably the largest potential issue.

    I think covering it if you're able is certainly "better" - but you're not going to ruin all chances of success or anything if you don't.

    Thanks,
    Rob
