Are there any harmful effects of OD'ing in fishless tank?

Will there be any harmfull effects of blasting co2 and dosing higher then normal concentrations into a fishless planted tank?

The reason I am asking is that I am attempting to start a low maintenance grow out tank, in which I would not need to monitor too often.

Thanks,
Jimmy

in order to use all the extra co2 and nutrients you'll be dosing you'll need that much extra light...

i think you'd end up with incredibly fast growth which doesn't lend well to low maintenance...

No problems that I can see - I'd go for it.

EDIT: ovenmit makes a good point, but if you just want a farm to produce plants, then crank those levels up! It won't exactly be low maintenance though, unless you keep the light levels cut back.

Ditto on what everyone said. The only side effect is a lowered pH, but hey, it's fishless.

In addition to the above statements, I think you are going to need to watch your KH. I chewed through mine (dropped it over 3 degrees from 8 to 5) when I had a CO2 OD.

Not sure how much you are thinking of putting through there, but something to keep in mind.

well, my tank will have 130w over 10g. Lighting should not be a problem.

What are the effects of low KH again?

Thanks again!

kH = carbonic hardness or buffering capacity.

It's the ability of your tank to resist changes in pH. Low kH can make your tank prone to pH swings. If you're keeping shrimp, you may want to buffer it somehow, but if you have liquid rock for water like I do then it may not be a problem.
