Ok so i have been offered the prospect of free electricity and am thinking about buying some mining hardware, what is currently the best hardware and what else should i be thinking about?

thanks

Its very nice that someone does offer you a free electricity which is really good to consider when you plan to build a mining farm.The best hardware for mining is antminer s9 as of now and you should consider first on what place you will put those miners and also think off the maintenance.If you could able to handle these things then you will be profitable and reach roi faster since you dont have electricity charges.

I just did a calculation. If the difficulty rise 8% every 13 days, you cannot ROI even with 0.01 dollar electricty price.

You got it man even the price of electricity would be very cheap or free but the mining difficulty would be your enemy and as you said it rises 8% every 13 days which means roi would be very longer to achieved but theres a way to be profitable since OP have a free electricity building a mining farm which composed by 5-8 s9's miner would be good.
