Do you have expensive electricity and can only mine at night?
I do not understand your problem, so I will give the main opinion.
The mining farm should work 24 hours a day, if you have problems with electricity, then look for other places where you can install your mining farm. If it is expensive or unprofitable, look for other opportunities to earn money.
A mining farm could actually even only run from time-to-time, just depends on the costs of running it (usually, the biggest factor being electricity).
Such moments need to be considered before buying a mining farm. If electricity is expensive, then it is better to buy cryptocurrency or look for other places where there is cheap electricity. Profit is already falling, and if the mining farm works 50-75% of the time per day, this will increase its payback period.
